- Neat little trick to get more explosiveness from SVS Subwoofers... Click MORE
I found this hack when comparing the PB-3000 to the PB-4000, and there was just a slight difference in the graph, and this change made the graph much closer.
Granted, a graph doesn't really show the true difference in explosiveness from 1 sub to another, and all ported SVS subwoofers have a similar "in room" response, which is to say a very deep sound.
The PB-3000 was released with some degree of concern, as several people at SVS were concerned that the PB-3000 would poach PB-4000 sales.
Rightfully so, the split wound voice coil really does give the PB-3000 extra kick that seems to be more impressive than it's 800 watt RMS rating would typically deliver.
There are still some strong reasons to go with the PB-4000, but the PB-3000 is for those who are more budget conscious, or just want a smaller form factor. The difference in weight alone is substantial.
And to be clear, an upgrade is still an upgrade, and there are other aspects to consider, but this Hack is just a way to get a real, noticeable sense of what an upgrade might feel like, and a way to get a little bit more out of your current SVS subs.

The goal of my channel is to be as helpful as I can to regular people, who might not have the time or the interest to dive super deep into the audio hobby.
I try to keep my content and responses approachable, easy to understand, and welcoming.
Nobody was born understanding frequencies, DSP, Dynamic EQ, crossovers, and SPL. We all started with no knowledge at all.
I feel that distilling years of exploring the nuance and unexpected audio lessons is worthwhile, hopefully saving you time, money, and countless headaches trying to make sense of it all.
I hope you find my content useful. - Věda a technologie
Like always, you hit the mark with another hack. I have had my dual SVS PB-16 ultras for over 4 years and I never thought that they could get any better, but with this hack, they are on a new level. I can't believe how explosive they've become. Thanks man, I hope to see more videos on SVS sub hacks using the app. Awesome.
I was waiting on a report back from someone with PB-16 Ultras, and it's what I was hoping for! It's the one sub I didn't get to try it with, but there's no reason why it wouldn't have the same effect.
I appreciate your kind words, and I'm happy you got even more out of those babies!
I had The Accountant but had never watched it, that 1 minute scene absolutely rocked by room - dual PB2000's WOW Thanks and glad to see you back adding content.
It's usually my first demo for people, then transition to a few other scenes, then some music to see that it doesn't need to be imbalanced or overdone to sound amazing for both movies and music.
Glad to be back!
Glad to see u in better health and making videos on my favorite subject. Keep it up sometimes life knocks us down, but your back doing what you love and that's great..
I appreciate it! Honestly, my health hasn't improved, a bit worse really, which is the normal trajectory.
But I am enjoying my life more than I used to, and it's nice to be producing content again.
The difference is the editing tools I use now. Artificial intelligence is doing a LOT of the frustrating, time consuming work that took most of my time.
I can cut 30 minutes of otherwise unusable video down to 12 minutes of usable video, in about 5 minutes. Something that size would typically take weeks of suffering.
My 1 v 2 v 4 video was shot in October. Just recently published it.
I'd been hacking away at it for months, causing severe symptoms. Only an hour or so at a time,
*maybe* twice a week, was all I could stand.
Found my current editing systems, and basically started from scratch, and I was able to get it done in 2-3 weeks, putting in the same time, (I'm still limited) but far less detrimental than how I used to do it.
A larger screen has also helped.
Overall, I'm happier, which means a lot to me. More enjoyment and satisfaction in life.
That's a massive win, even for someone in perfect health. I really appreciate the kind words. It's good to be back!

That's the main thing that you're join your life. I have watched all your videos and got concerned when u disappeared for a while.
I do have a question. I have 1 pb-2000 and want to get another one when I have the cash and find a good deal on marketplace. The PB-2000 i have now I got it for $400 with 4years left on the warranty. My question is should I move up to the new 2000 or will the original subs be good enough. I don't know that much about DPS and how to get it dialed in rite. I have a Marantz SR-5013 7.1 it has 2 sub inputs but I think there programed together. Could u give me pointers on how I would do that DPS or should I drop even more money and get the PB-2000 pro's.
@tommyboy3737 I appreciate it, I had a 2-3 year rough patch there. Definitely in a much better place and state of mind now.
A couple of points worth considering:
The PB-1000 Pro's are equivalent to the original PB-2000, despite the lower wattage. Every sub that got the app was a step up, not just a new model.
The app is not difficult to use, nor is it necessary to ever touch it if you don't want to. Definitely easy to learn.
The PB-2000 Pro's would be a definite step up, especially going from a single original to dual Pro's.
I'm not a big fan of mixing subs, so if it were me, I'd grab another PB 2000 original, or step up to a dual PB 2000 Pro set.
Granted, the closer the subs are, the better. So mixing an original with a Pro will still sound great, but the weaker sub holds the stronger one back.
Obviously I'd love for you to follow my affiliate links, but if you can find a cheap PB-2000 original, it would be the most economical move.
Also, if you purchased the original PB-2000 direct from SVS, you might still be able to trade up. If you're a couple of days over the 1 year mark, it's always worth asking. That might take the sting out of the cost.
Let me know what you decide, and ultimately how it works out for you.
I definitely appreciate your concern, it really does mean a lot.
So glad to see you back again, thank you for the info 👍
Great to be back!
Glad to see you back! 👍
I appreciate it!
I do have the Blu Ray of The Accountant, but, have not watched or heard it on my current system. I watched the scene you pointed out (wow, I didn’t know it sounded like that) (I do have dual PB1000 Pro’s) I changed the Peq, and watched that scene again. I did hear a difference. I wanted to get the 4K, but, maybe not! I listened on DTS:HD + NeuralX. Imma have to watch the entire movie.
It's a great movie in general, I really enjoy it.
I have the 4k version, but honestly if you have DTS Master already, you have the good stuff. Granted, if your set-up really shines with 4k over 1080p and you can easily tell the difference, then that's another consideration, but I typically look for the audio formats first and foremost.
Definitely a shocking scene to the uninitiated. Fun to watch reactions!
What Q setting would you recommend on the sealed version?
Why not just make a house curve? And would this work with a house curve? I have one sb3000.
So the when the Pre EQ is on, that top right corner light should be on or off? 🤷🏻♂️
Thank you
Is this hack specifically for multiple subs?
so the svs app doesn't work on pb 2000 non pro. keeps telling me sub not in range.
My wife said she could feel the floor shake upstairs. The Continental shootout in John Wick 3 was insane.
It's a fun little trick!
I’m gonna try it with my marantz cinema 50 Dirac live bass control using 2 pb4000s in front and 2 pc4000s in the rear.
I have to wonder if there would be a difference between boosting in the SVS App, vs Dirac?
Might make no difference at all, but it's remotely possible.
Whats to stop you from boosting +6db at 20hz, 30hz and 40hz? would it sound better, more umph? or just muddy?
I think it's a bit like seasoning, too much probably isn't always a good thing.
I like this particular hack because it still seems to keep the overall balance right. Not too crazy one way or another.
That said, experiment! See how it goes, you can always go back to totally stock very easily, just disable the PEQ's.
Disabling the PEQ's is also a good way to toggle back and forth to get a feel for the changes you're making.
I think if you're going to go ham with the PEQ's, it's probably a good idea to use Room EQ Wizard to see the results from the changes, and compare it to stock response.
Does this work with dynamic eq on or off?
So the way i understand this is, you run normal audessey, once complete go on svs app and add 29hz 3+db or more?
I keep dynamic eq on, and dynamic volume off, personally. And you are correct, you want your PEQ's disabled before running room correction, and do the hack after that's done.
It should still have an effect if you don't use dynamic EQ, but I prefer it, and flat rather than reference.
Would that hack work with my dual sb 3000 subwoofers even though they are sealed and considering room gain and such?
It will definitely change the response, just like ported, but I don't know what the actual points will be to make it sound good. If nothing else, it's a good starting point, and if you don't like it, you can easily disable it.
The in room response curve is a little different with sealed vs ported, and room size plays more of a role in how room gain will behave.
Smaller rooms have more low end room gain with sealed, but ported subs are less sensitive to room size. The smaller the room, the deeper sealed subs sound. Ported subs don't do that.
I could see your frequency point maybe being a little higher, like 33 hz, but that's pulling a guess out of mid air. 29 hz might still be ideal.
Since sealed varies with room size, there may not be a good, single frequency point for everyone, the way it is for ported.
The large living room and the small space in the motorhome both did well with 29 hz.
If you decide to tinker with it, let me know what you find.
Try some frequency sweeps, where the frequency is on the TV screen, and a few different songs that will flush out bad behavior.
Eminem's "kill shot" should be very powerful on the low end, but not overdone.
Metallica "Lord's of summer" should sound thick, punchy, and appropriate.
Holly Cole "Jersey girl" should be good and thick, but not overdone.
Alice in Chains *unplugged* performance "Rooster", "Nutshell", and "Down in a Hole". "Brother" is a little heavier than it should be, so I wouldn't use that as a reference.
If you have the Eagle's Farewell 1 Blu Ray, with DTS Master on (it defaults to 2 channel, and you have to change it every time), "Wasted Time", "Life's been good", and "love will keep us alive" are good.
During each song, you can toggle back and forth, and look for the improvement, as well as any negative effects.
When everything above sounds great, then you've got it right, and movies will be better as a result.
Trying to tune with movies is just too challenging.
I feel like I just gave you a homework assignment! Lolz...
@Subwoofer101 ty I will give the hack a try and my room is small that my sb3000s are in like 11by 13 feet with about 9 foot ceiling old house 1890. I gotta tell you though they sound very very impacted now as I gave them setup with a slight boost and q adjustment at about 16hz and about 2o hz too......not much mind you just a tad bit.and they play very deep if the material is in the soundtrack like the John wick movies or transformer movies....very gut wrenching a n d sometimes shocking impact.....I do have a very good ear for audio as I sold med to high end audio years ago when I was younger...now u am 67 years old....the audiologist keep telling me last 10 years that my hearing is about on par with 40 yr old as far as freq range....lol whatever that's worth....thank you so much!!! By the way love Eagles music and do have the farewell tour on blu ray too...got a very diversified taste in music!!!
Trying this tonight on my dual PB 3000s, thanks!
Right on!
Did you try it yet? I have dual PB 3K's also, so I'm curious. Thx!
@@sixohdieselrage I did, and it helped the low end really punch. Anything helps at this point. My duels are not properly tuned, and my room has terrible acoustics.
Thanks for the video ! Just a quick .. iam already using mini DSP for PC4000, can I still make this changes ?
Sure, it's always worth a try. I just ran room correction with the PEQ enabled, and I need to disable it and run it again.
It's just a good idea to have all PEQ's disabled for room correction.
It depends on what changes you made with the DSP, but just follow your ears.
You can also measure the difference with your Room Eq Wizard.
You can also make the same change with your DSP 2x4.
@@Subwoofer101 excellent, thanks for you inputs ! It's always worth listening to you ❤️
Do you know some good PEQ setings for more kick/slap in music?
Honestly, I would think your gain is too low.
That said, it depends on where you want that increase. Music is pretty broad.
I would also make sure your speakers are set to Small, and at least 90hz or higher crossover, even with towers.
Assuming you are working with SVS subs, you can run a lot more gain than your typical subwoofer.
My adjusting subs by ear is a good place to start.
If none of that brings you what you're looking for, keep in mind that some music just doesn't have the kick it should. White Room by Cream is a good example.
But if you want to play around with it, you can boost the 40-75 hz range by 2-4 dB, and a wide Q of .3 to 1.75 (the smaller the Q, the wider the effect on both sides of the selected frequency.
Try various frequencies, and see if you can hone in on what you want.
It will take some tinkering.
Also, if you aren't running matching dual subwoofers, a lot of that pinpoint slap is lost to the standing wave effect.
Kind of just throwing everything out there. Lolz. Let me know.
I am using 29hz, 4db boost and 2.5 q factor....But also using Audyssey reference instead of flat with dynamic Eq on.....For movies flat doesn't feel good to me.... Reference works best.. You please do some video on Reference vs Flat and its major impact on subwoofers especially
I think I might differ on my preference, I prefer flat over reference, but I'll take another look at it.
How did you determine 29hz?
Trial and error, using Room Eq Wizard to see the measured results of the changes, and then letting my ears give final approval.
If I just went with what I thought the graph should look like, I would've reached a different result.
I did that at first, but I didn't like the overall effect. 29 hertz gave me the results I wanted.
Great question for sure!
I can feel it at my MLP!
+3dB boost means twice more power, and +6dB boost means 4 times more power. Any risks for the loudspeaker and/or the sub amplifier ?
I've had no issues whatsoever. It's all just a matter of relatively.
At listening levels for most people, they are probably going to be in pain before the subs are.
Loudspeakers shouldn't be impacted at all as they stay at the same relative volume according to the main volume control of the AVR. Only the sub is affected.
@@Subwoofer101 sorry for my english ! I wasnt talking about bed layer when I said "loudspeaker". I meant "risk for the sub membrane"
@@Subwoofer101I ask the question because when you do EQ it's better to cut the Peak and not boosting dip to avoid distorsion and other issues. Too much boost is never good when you EQ
haaaa! long time no see xD
Thanks for stopping by! I plan to be much more active than I used to be.
What about PEQ2 and 3?
You can use them if you need to. If you measured a spike in your response using Room EQ Wizard, you could pinpoint it and shave it down to have a smoother response.
Generally speaking, I don't need to use them, because the response is already plenty good after room correction with duals.
Where they really come in handy is when you don't have room correction.
So when I put the Micro 3000 in the SUV, I had to be my own room correction, so all three PEQ's are used.
I'd use a frequency sweep, and based on the spikes I'd hear, I'd shave down those areas, using a high Q value for sharp spikes, and low q value for broad areas. As an example, I had a large spike between 31 and 45 hertz. That's pretty wide, so I used a 1.8 Q at 38 hertz and lowered the level by 5dB or so. Going from memory.
I had an even bigger spike at 33 to 37 hertz, so I used a higher Q 4.5, and reduced it by another 5 dB or so at 35 hz. So I had some overlap in the PEQ's, but sometimes that's what it takes!
Definitely takes a lot more time than room correction would, but it did the trick.
The biggest thing to keep in mind is that boosting a dead spot usually isn't a good idea.
Cancellations aren't typically resolved by boosting them.
Cancellations are resolved by having two matched subwoofers instead of one, and/or my distance hack, which is shifting the phase or timing to reduce cancellations caused by the interaction from mains and subwoofers.
Long answer to a short question, but if you don't need them, don't use them. Not harm in experimentation though.
@@Subwoofer101 I just recently downloaded REW, and just received the Umik-1. I am waiting on the boom mike, and I will than take some measurements. After using PEQ1, and listening to The Accountant, you’re right, don’t really need 2 and 3. I’m really pleased with the sound I get from my speakers, but, just wanted to see what they are doing in the room.
I have dual SB-16 Ultra
I'm curious if you've tried this, and your impressions. Sealed behave a little differently than ported, so I don't know how well it will translate.
I'm thinking the frequency would need to be set higher for the boost on sealed subs.
If I push my sb3000s too hard on low frequencies it sounds like it's gargling mouthwash 😁. I'll try this hack soon but likely will be a bit higher for the frequency
Gogo Joe, what is your subwoofer gain set at?
Large vs Small, crossover for each speaker channel?
I've found that the gain structure on sealed subs are more of a big deal, it's how I figured out the Gain Hack, on SB 2000 originals.
Essentially bottom out the AVR subwoofer level, +.5 (-11.5 out of -12.0) and raise the gain on the subwoofer to compensate.
I'm guessing your gain should be at least -15 on the SB-3000's, maybe as high as -9, I don't know for sure.
You can definitely run into clipping if the AVR subwoofer level is high, and subwoofer gain is low.
I'm not 100%, it's been a while since I've messed with sealed subs, but I do know that they require more relative power.
And if your speaker channel crossovers are too low, anything under 80 hertz, it can make proper integration nearly impossible.
I personally run Small 90 hertz at a minimum, no matter how big the speakers are.
Let me know.
