- One of the first questions many people ask when choosing a new powered home subwoofer or replacing an old one is, should I go with a ported or sealed box cabinet enclosure?
In this video, the SVS Sound Experts discuss the differences between ported and sealed home theater subwoofers as well the unique acoustic properties of each. You'll learn which type of subwoofer is ideal for max SPLs (sound pressure levels) and deep bass extension as well as which tends to be more musical, with tighter and punchier bass. We also cover the visual and physical impact each subwoofer has on a room and which is ideal for various listening preferences.
One of the SVS subwoofer design philosophies is to narrow the gap between ported and sealed box subwoofer designs. Meaning, SVS sealed box subwoofers have amazing output and low frequency extension and SVS ported box and ported cylinder subs are exceptionally quick with pinpoint accuracy and speed in transients.

I have a PB-1000 and it just kills. I love that thing, just need to go dual next, too many dead spots but the sub itself is awesome. For the money it's incredible. I find it great with both music and movies.
Thanks! Dual subs will definitely help with those nulls in the room..
With good room correction, the PB-1000 is all you really need. And dual is just awesome.
Lucky you... I'm still trying to convince the wife we need one! Iv'e even told her how lovely she is first thing in the morning,
when she actually looks like a bag of crisps!
I hate the question, "Whats wrong with the one you have?"
It's not an SVS!
"What's an SVS?"
A proper sub!
"I thought your current sub was a proper sub!"
Oh forget it, go back to sleep!
lol, love the transcript.
Frank, buy first ask permission later!
educating the public on the science of your product is really good advertising. i really think more companies should do stuff like this... and i'm not talking about fake advertiser talk, I mean real information like this video had.
Thanks for noticing. We're big on providing useful information over inflated hype.
That's because they sell both. So win, win. If they only specialized in just one design they might not be so forthcoming. Maybe?
I've has both ported and sealed subs. Ported gives you a nice rumble, but I find the sealed to be more satisfying for movies and music. Feeling the sound like an earthquake is cool and all, but I prefer the cannon ball blast to the chest that sealed gives you. Scarier.
Well said!
Great video, questions answered and information exchanged very quickly. Thumbs up 👍
Very good information. I just discovered this company about a week ago and am looking forward to adding some of your components to my theater room.
As i see it, when you have power and response, sealed is always a better choice. Except in situations where speaker is small and you want to compensate that with a big box that helps creating the deep sound. For example, that is why pretty much all small 2.1 desktop setups are ported. But in this case we are talking about 500W rms drivers that go down to 19 hz or lower. For me, frequency response is most important thing. I want my speaker to be able to reproduce everything i play through it. Then goes the power. So, when you play music or watch movies you want your speaker to be able to reproduce sound as quickly as possible, driver has to be able to return to its "default" position as quickly as possible and sealed does that better because of the vacuum that helps it. I have a feeling that ported woofers create sound that doesn't really exist. Because its "free", driver moves a lot longer then in sealed one and it doesn't have the time to go to "zero" when new sound has already begun. That maybe sounds more fun especially in movies where there is continuous rumbling but in my opinion that is just not realistic. And that's especially a problem if you listen to electronic music like me...psy trance or drum and bass...A lot of fast sounds at the same time so speaker can't separate them because it never stops moving. But when you have a 500W pig that goes to down 19 and is sealed...it simply does everything great. Plus, its small.
Anywho, that's just my opinion and how i explain the difference to myself. You guys have great woofers and although i am currently using 1 ported 160w subwoofer connected to my stereo amp and second 400W rms sealed car subwoofer powered by car amp which is powered by 30A/13.8v laboratory power supply and connected to my computer sound card (yes, it works like hell, got me sued for disturbing peace in my building and messed up rigidity of my kitchen elements :)), i am definitely planing to get SB-2000 to replace them both in the near future.
Thanks for the insights, you offer some excellent thoughts on sealed vs. ported subwoofers and your description of a sealed cabinet's advantage when it comes to speed in transients is spot on and the reason why sealed subwoofers are considered more musical.
Im sitting here waiting patiently for my BK xxls400 to be delivered. Its sealed and a bit of a pig (your words). i want it to have time to go to zero when playing my drum and bass and psytrance. your comment is calmimg my bones. Movies - meh, who cares. its about the music for me. Thanks :)
It just arrived - EEk
My thought exactly.
I really love all your videos. They are explaining so much that has confused me for a long time. Thank you.
Glad you found the info useful!
@@SVS_Sound Very much, thank you. I have two SB1000 Pro subs on order.
SVS has one of the best customer service that I have experienced. I have had subs of different brands in the past but SVS is quick as lightening to respond and make you comfortable with your purchase.
Ed Mullen and the other team members like Jack Gilvey are really great to interact with concise and precise replies in clearing out your doubts. What I like about SVS is that they hear you out and don't make you over spend but rather improve your existing purchase with their expertise. Their reputation is built on hard work.
Pls note that I don't work for SVS but have been their customer in the past and have had a great experience with them.
Thanks for noticing. Taking care of our community it as important to SVS as making amazing speakers and subwoofers.
@@SVS_Sound That's really reassuring for buyers.
dam you Home Theater subwoofer is almost as power as my PA dual 18 inch that are 1600watt rms and 6400 peak watt power, dam no cap @@SVS_Sound
fantastically clear and precise and correct information, thanks!
The acoustic suspension aka sealed box also has magnitudes less group delay.
I just ordered a PB 2000 Pro. This is the first subwoofer I ever bought, not sure exactly what it will sound like in my room, but based on everything I read, I’m very excited for it to get here
You guys are great at responding to your supporters of the channel! With that being said, in the foreseeable future could there potentially be dual drivers in a single cabinet with the 16 inch drivers?
Not with the 16's in the near future, though we will never rule it out.
well for my room the sealed sub is working fine...I would like to get two in the future!
Some of the technical differences they left out is that in a sealed design there's a law of physics that states that every time you go down 1 octave in frequency, a SEALED speaker must stroke back and for 4 times further to produce the same volume (loudness). in other words if the speaker is moving just 2mm at 80hz it has to move 8mm at 40hz and then 32mm at 20 hz to keep up the same level of volume. This typically causes a sealed speaker to get quieter and quieter the deeper you play at some point while at the same time it moves more and more the deeper it plays. Eventually it will move too far and either "run out of steam", damage itself or have significant distortion (or all 3). A properly ported design overcomes some of this by essentially having the ports "help out" where the speaker starts to fall into this "roll off" area. The ports help to boost the volume where the speaker is starting to have trouble (as the notes get lower) and they also dampen the movement of the speaker so the speaker moves less and less as notes get lower instead of more and more (at least up to the tuning freq. of the ports).
Overcome the problem with brute force. I am breaking in my PSA S7201 today. I've always had ported subs going all the way back to my car audio days. It absolutely does take a lot for a sealed sub to match a ported sub, this one bridges that gap.
lampim , exactly, it also takes more power to drive a sealed speaker system vs. a ported system.
Solution passive radiators
A passive radiator is basically the same idea as a port. Both the PR and the port have a tuning frequency and will invert the backwave of the speaker at certain frequencies which contributes more output as though there was an additional driver.
Super helpful video, thank you SVS
Glad it was helpful!
I recently got a svs sb4000. Thing is amazing in my small/medium sized room . Watched Mad Max Fury Road. All I can say is wow. Unbelievable bass for its size.
I am considering adding a second one just to add to the experience and won't have to work that single one quite as hard.
Right on, thanks!
I made my own sub 12 inch woofer in a 4 order bandpass box feeding it 2,400 watts in a 2 ohm load and it hits hard real hard!
Best of both worlds sealed and ported all in one!
video?
So what are the limitations of the ultra series subs? Particularly the SB16 ULTRA
great interview and great questions, thank you
Glad you enjoyed it!
SVS subs are VERY expensive here in Europe !!! While americans pay $2.300/2.500 for the SVS PB16-ULTRA, we pay at least 3.500€ ( $3996,04). Even the less expensive SVS SB-1000, we pay 600€ ($685,03), while americans pay just $250/300. I would love to have dual SVS subs, but it´s just ridiculous to pay 7.000€ ($7992,07) for two subs !!! For now i will keep my Rel Acoustics Storm 3...but one day i will buy an SVS sub...or a JL Audio sub. If i were rich, i surelly would buy the Legacy Audio Foundation subwoofer. Greetings from Portugal. Cheers
Hello I own a SB 3000 sub. Can you tell me if the PB 3000 can perform exactly like SB 3000 when the ports are closed?
What type of box shall I make for my Infinity Reference 9603ix (300 Watts) Speakers Ported or the Sealed type ? I am already using One JBL GTX 1300T Sub Woofer & Four Infinity Reference 9603ix (300 Watts) Speakers.Now I want to make Box for those Four Infinity Reference Speakers Plz suggest what type of box will sound best ported of sealed.
If my room is not enormously big and I go with two identical subs will I notice any difference between SB16 and PB16 in case of LFE? I guess that higher output level on PB16 will not really make sense as I will have to set them below the reference level anyway. And I mostly listen to music (90% of the time) and sometimes movies.
In the case of LFE, you will not likely reach the max output level for either 16-Ultra subwoofers, especially with duals, so there wont be much noticeable difference. Given your music preference, the SB16-Ultra subwoofer has the edge with speed in transients, an important quality for rendering instruments and snappy basslines with accuracy, precision and control. It still has plenty of punch and extension for movies but may be a better fit given the 90/10 split for music.
thats why im using a sundown sa 12 for my home theatre. going to build a custom ported box into 4 cubes out of my 8 cube shelf for an sa 15 to get the even richer lows, and so after displacement and box build its going to be perfect tune and spec for the sub
Looking to add a pb-2000 to my setup but the lack of a magnetic grill and the recent price increases have given an edge to the competition.
Talk about how the cheaper ported speakers can also offset the cone output and how the port can also make its own “wind sound”.
Nice review svs rocks 🎵🎶
I have been torn between the SB2000 Pro & the PB2000 Pro. I want a sub more for music than for a home theater setup yet I listen to a lot of bass heavy electronic music that reaches down to the lowest of frequencies (not mid ranged electronic music that's more main stream). It seems like the consensus online is that the SB is better for music and the PB is better for home theater due to its larger output and lower frequency range. How ever the response on the PB seems to be almost as flat as the SB. I would be doing most of my listening in a small bedroom that's about 10x10ft and a living room that's 20x20ft. I also produce music a little bit and want an accurate sub. I suppose in end my question is are those extra 3hz worth getting the PB and will the SB have enough power to relatively blow off my pants in a 20x20 room. Thanks!
Did you ever make a decision? I would assume the SB2000 would be the better choice for you.
This video was very informative . Learned a lot about the differences in ported VS non- ported. I've always wondered what the difference was.
Thanks, glad it was useful.
SVS great product, great service!
I Have Question @SVS, active subwoofer have amplifier inside, by too much vibration, this amplifier will not broke up?
The amplifier is reinforced as part of the sonically inert cabinet to ensure no damage is caused by the driver motion or energy.
When you guys talk about application and room sizes, it would be nice to put that in context. For example, room volume to subwoofer matching. How do I know if a PB-3000 is enough? Or duals? or a PB-4000? Or a PB16-Ultra. This is where something like THX marketing helps. You know based on a certain room volume whether you need Select or Ultra, etc. How do I get this info from SVS? Thanks!
Thanks for the comment, you bring up a great point. Since all rooms are different, it's best to email (custservice@svsound.om) or call 877.626.5623 or chat in with our support team who can give you the best recommendation based on room size and layout. We'll also discuss creating a separate video that addresses choosing the best subwoofer based on room size.
ports have no place in speaker design, its just a crutch to helps with output. sealed actually go lower since don't have the phase issue below port tuning.
sudd Lol Opening a can of worms there.
sudd Both can work great. In big rooms I think ported is better but in small sealed is. In small room you get room gain so the sub will go much lower and louder at the lower frequencys. This is Why the sb- subwoofers have that roll off slope, to take advantage Of small rooms
Bak Oe what size of room indicate as small room and big room for home theatre?
Hello, I'm trying to decide what would be better for my home theater, some help would be greatly appreciated. My home theater room will 1300 cubic feet, 17f wide 13f length and 8f ceiling. There will be a a walkway behind the media center with no door besides that it's a closed off room, I'm trying to decide between a pb1000 or sb 1000. Also it will be a domby atmos set up and mostly for movies. Thanks
Hi - If you are watching mostly movies and using for home theater, I would recommend he PB-1000 for a room of that size. It will play lower and produce greater dynamic impact and slam for your system.
I am looking to get a ported 1000 next month. Hopefully on cyber monday.
Do your subs suffer from the port turbulence? I'd like to get a PC-2000. Why don't you have it in sealed form (SC-2000).
Hi Dave - We do everything possible to mitigate against port turbulence, including custom-tooled outer port flares to ensure maximum airflow with no noise. I would encourage you to look at 3rd party reviews to verify the sound quality of our ported subwoofers at all drive levels. We tested both enclosures early on and discovered the cylinder cabinet acoustics are better suited for the benefits of ported subwoofer designs. If you'd like more technical information, please send us a private message.
Hi
I have two 30-watt 6.5-inch subwoofers that correspond to the old edifier r401 speaker.
I want to design a common subbox for both and then build,
So that it produces maximum volume and volume, as well as deep bass and sufficient vibration (the best and most optimal mode).
However, the space limit for this subbox should also be considered, which can be up to 35-40 cm wide, up to 50-60 cm long and up to 70 cm high.
In the speaker specifications, the minimum response frequency of the 32 Hz speaker is written, which is probably mentioned with its box.
Very helpful!
Overwhelming options!! :) I'm planning to build a home theater room. I am considering the ultra 16 sealed because the price of both ported is high. But what is considered a small medium room? I have no chance to go to a showroom before buying so I will ahve to make a decision based on reviews... excellent video
Thanks. Small to medium is roughly anything below 15x15. Above that, you'd want to go with 4000 or 16-Ultra, or dual of one of the smaller series. If you email custservice@svsound.com with specific room dimensions, we'll make a recommendation.
Both works for movies or music and both are good. it's all about the taste. For clear quicker detailed with sound quality SB and for boomy deeper bass PB.
Thanks Ed
How many SB-16 ultras would it take for a equivalent, spl output of one PB-16 ultra?
Output is frequency dependent. At 50-80 Hz they have similar max output. At 40 Hz and deeper the PB16-Ultra has progressively higher max output.
40 Hz 1.5X
32 Hz 2X
25 Hz 3X
20 Hz 4X
Very good explanation there
Thanks, glad it was helpful!
I have a dual PB-2000 setup and love it!! 🙌🏼
Me too. Will eventually get two more for the other corners. It's awesome as it is though.
advsoft Without a doubt. Dual is the only way to go unless you have such an overpowering sub. Experts say four corner loaded subs would be ideal to equalize the frequency throughout the room but I think dual does that pretty good.
Can you tell me when you said room size which is good ? My room 15 by 19 by 8ft. I’m planning to get sub. Which one is good for me. Thanks guys !
It also depends on your speakers and listening preferences, but in general, a single SVS 3000 Series model would be good for a room of that size? Or dual 2000 Pro Series.
Heres a question for SVS, can you do a dual sub mix of the PB3k and the SB3k? Or do they need to have identical qualities?
It's best to avoid mixing ported and sealed subwoofers as it can create phase issues. You can mix different ported or sealed models as long as it's with another of the same cabinet type.
You say sealed designs are generally tighter and better suited for music. What if I get a ported sub and run it in sealed mode (closing the ports and, if it has EQ settings, set it to sealed)?
Does this work for music in a similar way to sealed designs, or am I better off getting the sealed sub from the start?
I want to have the best of both worlds so I'm thinking to get a ported subwoofer for movies and music. When I need the sheer output I can always open some ports.
Yes, that is an advantage of ported subwoofers with variable port tuning, you can enjoy the acoustic benefits of the sealed design for music.
SVS so would you say sealing the port in a potted subwoofer might give desirable results? Is this even recommended? I remember people use to stuff a pair of socks in the port to tighten the bass output
SVS I'm curious about dealing through ports for musicians well! Recommended?
easy man. . just build a box which is both ported and sealed.well u get both advantage.I did it and its cool.solved?
I put a foam inside the port of my z623 to lock the port because lower frecuency around 40 hz is very loud, works very well and can turn up the bass dial to get more midbass wihout having the low frecuency overpowering
Can you please give examples of a small room and a large room? I have a 20’x24’ living room/home theater room. 90% movies and 10% musics. What SVS subwoofer do you recommend? Thanks
Room size is not as important as many people think, it's more about listening preferences and the speakers you are running. That said, anything smaller than 12x12 would be small, 20x20 is medium, and from there, its large. Depending on your speakers, dual PB-3000s or a single PB-4000 or PB16-Ultra would suffice. We also have our subwoofer matching tool here: www.svsound.com/pages/merlin
Dual PB-1000's great for both along with Prime towers and a center plus 4 sat. going on 2 1/2 years now.
Thanks Toby!
I'd like to add a subwoofer to my bedroom and am looking at the PB-1000 and SB-1000. I don't know the exact dimensions of my room, but it's definitely not large. I'm into music, movies, and gaming, so I was thinking that the PB-1000 would be a good compromise to satisfy all of those areas. It might be a little overkill for my setup, but I love hard-hitting bass! Any recommendations are greatly appreciated. Maybe a smaller subwoofer would be just as good? My budget is $500.
The PB-1000 would certainly be a great option if you like deep, hard-hitting bass. It's also very musical for a ported subwoofer so you'd get great response for anything you're listening to. The SB-1000 will be a little quicker and punchier, but not as capable of massive output or depth so I think your first instinct of PB-1000 is right on for a $500 budget.
Looks like my eyes are set on the PB-1000 then! Appreciate the help, and thank you very much for the quick reply.
I would love to hear more about placement. Is there a difference difference in that aspect?
Great questions. Sealed models tend to have enhanced bass when placed in a corner of the room (corner loading). This blog helps explain the science in ab bit more depth. www.svsound.com/blogs/subwoofer-setup-and-tuning/what-is-subwoofer-room-gain
I always wanted to see a svs in action I need to upgrade from my velodyne ch10
The battle of the titans.
This question is for Ed: Can a SB16 Ultra be paired with two PC13 Ultra (2 ports opened)?
Yes - they can be run together, but you will achieve the best results when the two PC13-Ultra are run in Sealed mode. Mixing ported and sealed subwoofers can sometimes result in phase cancellation due to the differences in phase response, particularly near port tuning. -Ed
At the moment i just got one Dali basis 100. But now i want better base for my 5.1 system. Will start to buy one and add one more later. I'm not realy sure what i should get at the moment. Listen to both music and movies. I have checked your sb 2000 but im abit worried if it's too low output, becouse its realy small. I got a apartment and pb 2000 are abit too big for me i think. /cheers
You may be surprised by the output and extension of the SB-2000 since it has significantly more amplifier power than the current model you own as well as additional driver surface area. It can hit below 20Hz (the limit of human hearing) and really energize a space so I think it would deliver what you need.
In a multi-sub setup, should you keep the woofers of the same type, or might it be a good idea to mix sealed and ported?
Never a good idea to mix sealed and ported as it can create phase issues, which results in misaligned bass. Always keep sealed with sealed and ported with ported and match the driver size and amp power as closely as possible as well.
@@SVS_Sound Ah, thank you, I was thinking 2 sealed (back) and 2 ported (front) (same series) with active dsp (MiniDSP)
How to get svs sound systems in india...???
What if you bought the ported SVS subs, and anytime you wanted to change the way it sounded just plug the ports from none to all three ports to figure out what best fits your room or you can ajust to what you are listening to, I believe SVS has round foam port plugs to do just that.
Yes, our PB-3000, 4000 and 16-Ultra subwoofers all come standard with port plugs so you can change the tuning frequency of your subwoofer based on listening preferences and room response.
svs sb ultra 13 is "the one"
Are the same transducer used for either box?
For most of our ported subwoofer designs, we use what's called an underhung design , while sealed uses an overhung. This video helps explain the differences. czcams.com/video/6oDfPbT0H5w/video.html
What is the minimum distance we must keep the sub in order to hear the accurate low frequencies in a song? I have a Kenwood SW-305 which is a Ported subwoofer and im not able to get the exact response whereever i place, but if i go past my room to other room im hearing very nice response, unfortunately my room is smaller i think....it also has crossover controls and reverse function but it didnt help much either...
Wish we had a better response, but it really depends on the room. One thing that would definitely help would be adding a second subwoofer to smooth bass response throughout the listening area.
@@SVS_Sound thank you that makes sense since we have two in everything...
Joseph Karthic Placement is key, both listening position and Subwoofer placement.
I had to lean on my bookshelf speakers to aid in the 50hz + area as placement of my subwoofer is very limited (see it on my channel, it's a bit big for my room lol)
Normally adding a second sub is one of the easier ways to smooth out the response.
But you make do with what you have and learn as you play around with it.
Is extended mode a compromise between sealed and ported, or for another purpose.
Extended mode allows you to get slightly deeper extension without as much output. Not so much a compromise as an adjustment to personal tastes.
I have a 15 square meters room then and thinking of sealed subs for my room then. Movies/music and video games is 1/3 for each then.
As much as i love svs...i use 2x 18 inch jbl jrx100 passive subs i use a crown xls1502 4ohm 1225watt in bridged mono crossovers set to 47.5hz and these subs are ported...ideal for home theater.
Super happy with it and lot cheaper
Michel Linschoten Same, I personally use a Dayton Ultimax 18, and recommend them. (Dayton in general)
But to the non DIY inclined people, I recommend SVS as I see alot of good things from them.
Sadly haven't personally heard one yet.
After trying both sealed and ported in car and home theatre, I prefer sealed in car, and ported at home.
Can the SVS sub play at 136db with less than 1% harmonic distortion at 20hz?
Not currently.
What about now? Any new and exciting products on the horizon?
Ported subwoofers output will always be out of phase and you'll feel that it is lagging behind the song if you don't have a proper dsp to adjust the delay. Go with the sealed sub for the sake of simplicity.
if I seal a ported subwoofer box will it make the bass sound cleaner and more flat with less high peaks?
We don't recommend sealing a ported subwoofer unless you have the ability to change the port tuning frequency of the subwoofer, as you can with our 3000, 4000 and 16-Ultra subwoofers. Plugging a port can cause the subwoofer to be less accurate in frequency response even if it does give it slightly better transient speed.
realflow100 I tired that when I was learning back in the day... Long story short, save yourself the trouble and buy a better subwoofer when you can afford it. While it was fun, unless it's designed for that, it's pointless.
I hear SVS subs are good. (hint hint)
I have a PB13U and it's awesome at rocking the listening sofa when the movie soundtrack calls for a lot of 15-30hz effects. However it's just not punchy. It can't slam my head to a wall in a way a great sealed, high capability sub will. Can't have it all. :-)
Satfgk you want something that can slam your head to the wall? lol...
My PB13 U slams the hell out everything and everyone in earshot. Just curious about how you are running it? It's a slamming beast...
What exactly qualifies as a "larger room"? I am planning a home theater that measures 25x14x10. Is that a larger room?
Yes, that would be on the larger side.
Just purchased 2 svs SB3000 to go with 4 RP8000 and a 64 iii center.... I can't wait to get it all hooked up. Running a Denon 4500h... was wondering if I should have gone with the pd3000. This is not a dedicated theater room. It is the living room for the home, that is 23'×17' with vaulted ceilings I go from 15' to 8' high with three opening to other rooms. 90% of the use will be movies.
It's a different kind of sound, but dual SB-3000s will absolutely take control of that space and provide effortless bass response below the limits of human hearing. If you're still wanting more, please send our support team a note and we can work with you, custservice@svsound.com
Clint Qualls that'll all come down to personal taste, I know people who regret getting sealed as they just want the most output, but they didn't know until after they got the subwoofer.
I'm sure both sealed and ported SVS subs sound great though. (Never experienced one yet)
I have the Ultimax 18" and I don't think I could sacrifice my big ported box for sealed accuracy. (It sounds great as is already)
Guys, i want to purchase the svs pb16 ultra (bas reflex version), but i still don't know what speakers and receiver to fit with it.
The receiver is not as important since the PB16 has it's own internal amplifier. There's a lot that goes into choosing speakers, but our Ultra Towers and Prime Pinnacle speakers would blend seamlessly with the subwoofer and wouldn't require a ton of power.
@@SVS_Sound Thank you for your answer, Prime Pinnacle are on my wishlist anyway ! :D So now, i'm sure what to get.
Can I combined the ported and a sealed in one room, it is fine?
It's generally best to avoid using ported and sealed together because it can cause phase issues which results in bass that isn't blended as evenly in terms of timing.
So no accelerometer on it?
Can you include a ported and a sealed sub in your 7.2 system or do you have to match up two ported/two sealed subs?
Hi Robert - We don't generally recommend mixing ported and sealed subwoofers because it doesn't get you the best result, but with some DSP, you can blend them pretty effectively. As an alternative, many SVS ported subwoofers have variable port tuning so you can plug the ports to achieve a sound that is closer to a sealed design in varying degrees.
ok what is the difference in sound between a sealed unit vs a ported unit that is sealed with the plugs? is it comparing apples and apples or the sealed ported unit with a larger cabinet size has different sound characteristics?
The ported subwoofer with plugs will provide slightly deeper extension and output than the sealed unit. It wont quite reach the same level of musicality and crisp transients as the sealed, but it narrows the gap significantly.
@@SVS_Sound wow thanks for the detailed response. Can i ask another question? your website let's you pair your current speakers with an svs sub. I have a set of edifier s3000 pros and it says i should look into the sb/pb2000 or sb3000. How is this calculated? Would a pb1000 be enough?
Superb
So
ported = lower and louder
sealed = better precision
I personally am willing to trade the precision for lower notes at home. In my car I think ported boxes take too much space.
Yes, that's a simple way to explain it.
Actually, sealed designs have a much flatter response. Ported subs go louder, but their frequency drops like a stone after their specified frequency, say 17 hz. A good sealed sub, with a similar frequency rating, will extend to as low as 8 hz in the right room. Not as loud, but definitely more tactile.
Always Ported but with very good BoX and tune
What about ported vs passive?
John Smith Forgot I made this comment, lol. I think I was asking if a ported enclosure is better than an enclosure with a passive radiator. I just worded it poorly.
Sealed all the way for me unless a servo sub.
In a smaller room, would a high quality sealed sub or ported sub be better for action movie with lfe?
Hi Davide - In a smaller room, the sealed sub generally works better because it has a smaller footprint and the additional room gain can produce punchy, high impact bass. If floorspace isn't an issue, a ported subwoofer will give an edge in total output and low frequency extension.
I live in a condo building and the living room that I plan to use the sub is 17' X 12', my question is would the ported or sealed be better if I want room shaking bass that I can FEEL at really low loudness levels, I can't play anything loud or the neighbors will complain. sucks to be me.
My suggestion, regardless of what the cabinet type will be, is to try and put the sub closer to your listening position. This will allow the sub to vibrate the couch or whatever you're sitting in at lower volume levels giving you that impression of feeling without having to have the listening level too high for your situation. Another option you may consider (although I don't have any personal experience with this) is a bass transducer. In short it vibrates whatever it's mounted to to simulate the feeling of bass. I've heard both good and bad things about them but could be what you're looking for.
Andrew - A sealed subwoofer will give you great punch and slam at any listening level while the ported will go lower and produce greater output. It sounds like sealed might be your best bet and you may consider an SVS SoundPath Subwoofer Isolation System to accompany. It decouples the subwoofer from the floor so the energy is not transferred into the walls and ceiling, but rather into the room which lets you feel it at lower levels while keeping the neighbors happy.
Thank you. A sealed one it is then, and SB-16 Ultra will work for me at low volumes correct?
Andrew Wong ported if you really want bass I have a jbl control 10 it's from the 90s the bass is still as good. But yes my friend ported so you can hear the sub low frequency
I am already using a dual sub config that consists of an Energy S.10 and Definitive Technology SuperCube II. I just want more punch at a really low listening level. I want to feel it. Not hear it.
I have a logitech z506 sigh meanwhile theyre talking about 2,500 subs while my entire audio system is 100 dollars
Edit:I'm only ten so I guess it evens out because I have a mini home theatre in my bedroom
That's a good start, keep building and having fun with it!
That's cool make a video on a bass test.
That just means you have something to look forward to when you grow up. Just remember to protect your hearing (no loud headphones) so when you do get older you can still hear well enough to appreciate it.
Kavvy, good choice on surround 5.1 for your own “bedroom theater.” I had a similar Logitech desk/workstation setup after graduating from college for my first job. Now I’m rocking Atmos and reviving quadraphonic music mixes. This is a good video because it presents sealed vs. portable concepts that have some commonality across manufacturers; even Logitech has options for ported and sealed. ‘Learning’ and ‘spending’ money are two different things - in fact, ‘learning’ more of what you like and appreciate will help you ‘spend’ less.
@@rossimarti Oh no you didn't just use quadraphonic in a sentence.
what is the difference between a car subwoofer and a home theater subwoofer. Can I able to play a car subwoofer by connecting it with a amplifier and a crossover in my home. Please advice......
It' generally not recommended to use a car subwoofer in a home audio setting. Home subwoofers tend to be much more efficient so it would require more power to get a car sub to play equally loud since home subwoofers are specifically designed to fill larger spaces. There's also factors around impedance values and general cabinet design that make using a car sub for home theater impractical. You are much more likely to get a great home bass experience at home from a subwoofer designed for that application.
Thank you sir.
there are certain car sub-woofers that can be used in diy home applications like a JL W6 or W7 in fact the SVS subwoofer resembles the W7 design.
@@yaghiyahbrenner8902 This is what I call a gangster system.
I love you man.
So what I take away from this is that lets say the SB3000 and PB3000 will sound exactly the same for movies until I reach the limit of the SB3000? Only beyond that limit the difference between them will show?
Not exactly the same. The ports give the PB more palpable output where as the sealed cabinet tends to be quicker, punchier and more musical. This extends across the entire low frequency spectrum. The ports and larger cabinet also allow the PB version to dig a bit lower. That said, SVS has worked very hard to narrow the delta in performance between the two cabinet styles.
@@SVS_Sound Thanks for the detailed response.
What is the perfect SVS theater System for a basement area1400 sqft. $4000.00 buget two woofers
Tough question there as there are a lot of variables. You can't go wrong with a Prime Pinnacle Surround System (www.svsound.com/products/prime-pinnacle-surround-system). For that sized room, a PB-2000 Pro or SB-2000 Pro would be solid and total cost would be just around $3,500.
I have a Logitech ported subwoofer part of Z 323 speaker system
6th order bandpass is your best bet if you want the best output and bandwidth, but this requires building your own enclosure since no company makes these enclosures.
I have one in my room for a single 12” sundown sa 12. Rear section is 2 cubic feet tuned to 20 hertz with 5sq inches of port area per cube, front section is 4 cubic feet tuned to 45hertz, port area is roughly half of cone area.
It plays completely flat from 13 hertz to 53 hertz within a db or 2
I'd like to build my own sub but alas my house has no space for woodworking projects. WRT best sounding sub I think a servo controlled open baffle is best for music.
Passive radiator subs are best, if designed properly but SVS do not make one. They offer the best of both worlds and I have had many of each type myself.
you should try a tapped horn
How about having one each in my setup?
It's generally recommended to stick with ported or sealed and not to mix. If you choose ported , some models (like the SVS 4000 and 16-Ultra Series) have variable port tuning so you can plug the ports and run with an optimized frequency response in sealed mode. That gives you the most flexibility.
I've had that setup in my system before, and I just couldn't get the bass balanced in my setup when playing music. I'm not saying it's impossible to get right, but in my rectangular room, no matter what I did, the ported sub would always reveal its location in the sound stage, particularly when reaching the lower frequencies. I tried tuning the ports, which improved it a little bit, but in reality I was only changing the sub to operate in the way it wasn't designed to. Got rid of it, because I realized by then that I obviously prefer the characteristics of a sealed sub.
Sigurd Endemann, I bought two sealed subs. They may not be the lowest but it’s enough for my theater and music sounds incredible.
Have just changed my a SVs pb 200 sub paired to Canton dm 75 Soundbase to a Samsung q90r atmos set up.
The new speaker works well with great sound separation and does the job however I can honestly say the base is although it does it’s job it’s almost boarder line pathetic .
The moral of the story I guess is if you like your base there ain’t no going back after Svs.
How does plugging a ported sub compare to a sealed sub?
The ported subwoofer will still have greater overall output capabilities and the sealed will still be a bit more transient and musical but it narrows the delta significantly.
Is a down firing sub better?
It's just a different sensation, not better or worse. Our down-firing ported cylinder models perform and measure almost exactly the same as our front-firing ported box models, they just require less floorspace and release air through ports in the top instead of the front.
Less critical placement -- against the wall. Unlike rear ported.
I was disappointed they didn't talk about different genres of music. Psytrance for example needs lots of bass and I much prefer a ported sub then a sealed. out doors it should be a front folded horn. Im surprised he didn't mention a passive sub as an alt to both sealed and ported when talking about music
That's a great point, certain music definitely favors ported over sealed. We may need to drop another video to dive into this topic a bit deeper.
Ported subwoofers all the way!
حاجه روعه
There's a reason why JL audio doesn't make any Ported subs look into them before making your decision
Seems like the jbl hdi 1200 is ported! I have the jbl l890 and I was looking fir something better from jbl,and hoped this hdi 1200 to be sealed to! Anny advice?
shagrathborgir2003 I think he means “JL” audio not “Jbl”
@@marcuskoolrt jbl....there is no jl! Also,seems that jbl hdi 1200 is ported,so no sealed jbl sub,after l8400
Passive radiator: The fuck am I? Chopped liver?
Ported for me. As a Mobile sound operator that plays non stop my speaker should be vented otherwise it will be cooked, specially when performing in a battle of the sounds where you push your speakers almost to its limit.
