LFE+Main Subwoofer Mode Explained
Vložit

- I find there is quite a bit of confusion regarding the LFE+Main setting in Denon and Marantz AV receivers. Some think it duplicates LFE from the subwoofer into the towers - but it doesn't do that. So, what exactly does LFE+Main do, and should you use it? Let's discuss.
- Zábava
Great explanation.
I had no clue what it meant for several years until I actually bought a higher end avr that had the explanation given on the setup screen as well as a detailed explanation in the manual. Great explanation.
Best explanation on this I’ve found so far. Thanks for the clarity
Great video. Extremely helpful. I just bought a Cinema 50 and had the exact questions you addressed. Your time and effort is appreciated. 👍🏾
How did you set your system up. I just bought the cinema 50 and for the death of me i couldn't get my subs to work. I didn't have this issue with my Yamaha, first time marantz user and already don't like this.
Great Great explanation of LFE + main. Thank you for posting. I have always wondered how to properly set up my subwoofer and this video helps a lot.
i seen so many videos on this and only this one makes sense.Thank you, sir.
glad it helped!
Thank you, someone finally explained it so I could understand!
Great breakdown Sir! Also note that the crossover in your subs should be turned up to the highest point to keep the two from competing (sub crossover and receiver crossover). The receiver is the primary EQ component.
Do you know how can I tell if my receiver has a built in crossover? Or perhaps all the receivers with subwoofer out have built in crossovers?
1st time i understand what LFE really does and how to configure it! Big thx !! :)
Best explanation so far!
Thank you for this!! I've just got into a high end AVR system. Currently running a Marantz Cinema 50, with Polk Reserve R700/R400 front and centre, and two SVS SB-1000 Pro subs. When listening to stereo music I was wondering why I was not getting any "extra" bass as the towers seemed to be doing most of the work. But this explanation made it all clear to me, thank you! Now I can go back and tinker some more!
Lucky you getting a set of R700's.
Im hoping i see them in stock in the near future as id really like to upgrade from my 30+ year old Klipsch KG 5.2s.
Every review ive seen on the R700's have been nothing short of stellar. Though id really like to hear them in person. Unfortunately I live in northern Maine and to my knowledge, no place in Maine has a listening room set up with them.
@@markvogeler7564 I have to admit that I hadn't realised how in demand these speakers are, even I ordered them back in December. It did, however, take a month for them to be ordered in from Sound United and then delivered. You're right, the reviews are all nothing but positive, and the sound, to me also, fully justified the cost. I am hoping to improve upon what the Marantz can give them by eventually getting two monoblocks to power them.
So everyone we listen to music we have to turn on LFE plus Main I guess
@PIPERBOYWILLIAMS you can go to the option=2 channel. And set it for 2 channel listening, main+Lfe, change fronts to large, that'll automatically be set for u when you choose 2 channel playback. Have it set definitely in the area he showed so it's back to small when listening to anything other then 2 channel playback.
Also, set your main crossover at atleast 80 hertz, that way your not getting real low bass. Same area, 2 channel.
Thank you! great explanation, I have set it to LFE only and all speakers set to small, immediately I heard a better sound difference, so this is the best setting / option in my opinion.
Super clear explanation on the subwoofer settings, thank you.
youre welcome!
Thank you for explaining this.
Ive been recently setting up a system in my new home using some new and some older components.
Marantz 6006 reciever
Marantz 7055 amp
Klipsch KG 5.2 main towers
Klipsch R-120SW sub.
Though the KG's are very dated and still look and sound like new (new bass drivers several years back after one voice coil smoked) ive struggled to get the sound I had hoped. Being very new to Marantz products, ive been trying to learn the settings with very little information available as that reciever is a bit dated as well.
I did speak with a tech at Marantz and they told me to set it to LFE and the main speakers to small. Which I did. Prior to the new amp i received last week. Though with the added power of the new amp, i believe i set the mains to large and have since struggled to get low frequencies to not sound mushy.
I suspect this having my KG's set to large and them playing full range is why its mushy.
Ive also had to turn my sub power way way down in order to not have a huge peak between 40 and 100hz.
Again, now this is all starting to make sense now so tonight ill have a far better direction on what to change and most importantly - why.
Thank you again.
Mark
Excellent video my brotha!! My little 510BT is set correctly now, good lookin out!
Holy crap that makes so much more sense now! Thanks!
Thank you, I was looking for exactly this
Excellent explanation 👍
Very well explained. Clear. Thanks a lot !!!
Thanks for making this video. It help me setup my surround.
Thank you for explaining this head scratcher to me 😊👍
saved my ass i found a $500 sub at goodwill and i’m using it now with my dads old bose speakers and denon reciever, thanks for the explanation i feel educated on it now!
Great explanation. Thanks.
Great info, well delivered. Thank you
My front speakers are massive 15 inches woofer, without LFE+MAIN they sound starving , when is enable they go back to life .I have 2 subwoofers with my denon and I have the independent subwoofer output feature , Also my front stage is power with 4 channel external power amplifier at 150w each channel at 8oms so my Denon receiver have a easy job for only powered my rear ant height channels .By the way your explanation is clear and very intuitive
Put it then on 150 hz not 120, bass will be more straight and not rumble. Try it I would say
Very good clarifying explanation! I also have my speakers set to Large because they look large to me, I didn’t know it messed them up like this.
My 5.1 Bose system I have them setup as small of course because they are small but my B&W are Large so that’s why I set them up as large.
Frankly the manual doesn’t really explain this at all and this is a very confusing subject and a lot of trial and error.
This is the reason most people nowadays just buy a soundbar, it’s fast and simple and sounds good.
The whole industry needs to simplify the system.
My center has always been muddled when playing Atmos material, I have a decent mid range set up running Svs 2000 pro, just changed from a Denon 960h which I loved to Sony an 1000 for the center channel features, still muddled. Over the course of a year I’m still trying to fix this maddening issue, I think you have helped and will be applying your advice. Thank you
Finally someone that explained it to me! 😁
YES!!!
explained perfectly really helpful thank you
Very Informative! Thank you!
What a explain i would like to see more video Sir Great Job
glad it was helpful!
Very informative video.Glad I found your channel.I have subscibed.I too have the Svs Pinnacles with the Ultra center and prime towers for surrounds.What do you suggest that i have all my settings at?
Great video. Very informative. Appreciate the detailed explanation.
Quick question, what's the rationale of setting the LPF for LFE at 120 Hz and how would varying this impact the sound output of the Sub and/or speakers.
I am using a Denon AVR with Definitive Technology Prosub 600 (5.1 set up).
Thanks in advance.
The dedicated low frequency effects in a movie (the .1 in a 5.1 audio configuration) maxes out at 120Hz - that how its encoded.
Such is why the LPF for your sub should be at 120Hz or below. There is literally no encoded LFE information above 120Hz for your subwoofer to play. Also, if you set your subs LFF above 120Hz, youre adding unintended bass and risk localizing your sub.
Nice video. Just one question. Are the other channel's low frequencies evenly distributed when running multiple subs or does the avr select the sub that is physically closest to the specific channel in need of frequnecies below 80hz?
they should be evenly distributed amongst all subs
Great explanation video, thank you.
I am a newbie trying to learn. My current set up is 2.0, but I want to change to 2.1.
My receiver (Yamaha R-N602) does not have a bass management menu). The spec says the subwoofer pre out cuts off at 90Hz. The Yamaha website confirms that the speaker terminals get the full signal. Can you explain how this is different from the LFE plus main situation you describe in your video? In other words, why are my bookshelf speakers not crapping their pants?
Also, what do you think of the idea of connecting a subwoofer to the speaker terminals in preference to the subwoofer pre out (as advocated by the likes of Paul McGowan PS Audio)?
Great explananation, very helpfull
Hey thanks for the video. It’s very informative. Question: Could this setting work while using the preamp out for your front active (w/built in amps) speakers?
yes
awesome explanation! thank you!!!
Thanks for the explanation, it is the first time that I finally know what all these settings actually mean.
One question, if possible, power-wise, is it better to rely most on the sub than the main speakers?
Thanks for the informative video. I recently upgraded my front L/R speakers to the Definitive technology BP-9060's. I also have the CS-9060 center channel. Using a Denon X4500H receiver with a small 8" Pioneer subwoofer. Should I set them to small or large? Just use the standard speaker wire banana plug connection or use the LFE input?
LFE and small is recommended, unless your towers have 10" or larger woofers in them.
Great explanation!
I’m using a simple 2.1 for both music and movies (2 x bookshelf speakers and one sub)
Use LFE mode if you want the sub to take over all low frequency duty, and free up the front speakers for higher frequencies.
Most recommend setting the crossover at 80Hz.👍🙏
LPF for LFE at 80hz as well or only the crossovers for the others?
@@AlexTurbo LPF at 120 Hz the others at 80 Hz
Really helpful. Thanks!
Does the Main setting give any "unique"bass (to the sub) that isn't already present on the LFE? In other words, does lfe ever leave out some bass that should be there?
Nice way to explain
Hello, I have the Marantz Cinema 60 and I mostly listen to music from the two main left and right channels for stereo sound. With a sub and B&W CM10 S2, what should my sub and tower speaker settings be.?
Thank you, Frederick.😊
Also handy when having good front speakers set the subwoofer in off, fronts on large en center and then listening, it can get better without sub. And more clear and better also.
Hi...rel subwoofers say set avr to large for the fronts...but if u have the fronts to smal and use lfe and main will it make a difference to bass
Thank you sir for this info.🙏🏽
can you make every video about sound systems. this was the simplest to understand great job. question: I am going to follow your advise in this video do you recommend using only the LFE input on my sub or set up the way you said in this video and use a Y splitter and connect both ports on the sub. I see a lot of videos on a y splitter ? pros cons
I recommend using the LFE input.
My LPF is set to 80Hz but as you said , this depends on the Room and the Speakers of course
Any reason you set it so low? Movies are mastered with a discrete LFE channel at 120Hz.
@SteadyChaos Productions the lpf is the crossover frequency from the speakers to the subwoofer. My main speakers Elac FS 68 got a frequency range from 38hz to 25000hz. Obviously the 38hz are not very realistic. Setting the lpf higher than 80hz I am loosing the nice kick bass from my speakers. The 120hz discret lfp is still supplied up to 120hz to the subwoofer.
@@GamingTech-CZcams i see what youre saying, i thought you were referring to the lpf for lfe.
I have Klipsch Cornwall II Speakers for my Front Land R. I bought a Marantz SR5015 last year and as I love it for 5.2 movie watching I have played with it for HOURS trying to get a great sound for 2 channel audio listening with not much luck. I eventually bought an amp switch and when I want to listen to music (which is most of the time) I just switch back to my old Pioneer SX 1050. The Marantz doesn't sound bad but its night and day as far as lacking that punch and deep bass and fullness from the speakers that my old 2 channel receiver gives them. I tried LFE+Main and just LFE. Ive messed with crossovers and its a little better but I wish I could just find a way to get the Marantz to just send full range to them and the ability to play with the bass and treble like the old receiver. Ive tried direct and puredirect but theres just not much low end when I do this. Are the newer receivers just not the same when it comes to music or am I just not setting it up correct. Any help would be greatly appreciated. BTW, My menu looks just like the Denon in this video or at least very close I think. Just as a side note I don't even run a sub when using the old receiver and it walks all over the newer Marantz even without one. Im so lost :)
did you set your towers to large? That would play full range. Also, when you play music, change your audio to just stereo. Also, make sure to level math your speakers and subs with an SPL meter.
Stereo from CDs & mp3s is far superior with LFE+Main enabled. Should be a feature on remote controls as far as I'm concerned or automatically set when "Stereo" is selected. It's also a feature on Marantz. I do have full tower Klipsch RP-8000f IIs so that probably makes a difference.
There is an option under stereo to make special settings only for stereo mode. Such as life plus main or using your mains as large or small. Great feature!
Would this be a good idea for people with good towers and only 1 sub? I have psb mission t towers and an svs sb-1000.
good on ya man great video
Oh. Now, I get it. Thank you.
What if you have your tower set to small, then set the crossover frequency to let's say 50Hz will that then allow my towers to play lower but not quite full frequency and then LFE plus main, then my sub plays the lower frequencies??
Yes, with LFE+Main, your subs will play low frequencies from your speakers set to small below the crossover. If set you set your speakers to large with a crossover, then all the speakers would play every frequency and your subs would also duplicate said frequencies below the set crossover.
Great explanation! But I have a question for my specific set up. I’m using Yamaha tsr 700 for my LCR I’m using kliosch KLF 10s and an rc 64 the Klf can go down to 40 hz and the rc 64 can go down to 50 hz. I want to get the most out of my towers. Do I set to small with cross over at 40-50 hz or set to large with LFE + main? For the center I have set to small and cross over at 60hz should I also change this to large?
try both LFE and LFE+Main to see what sounds better to you. LFE and set to small is recommended by most professionals - though you could play with your crossover to get the most out of your towers.
@@steadychaosproductions3376 thank you for your reply that’s kinda where I’m at now LFE with fronts set to small at 40hz center set to small at 60 and rears set to small at 80hz. I’ll play around with it.
Great vid
Excellent
Hi! Great video! I would like to know you personal preference. You set your speakers to small and 80Hz or large with Double Bass and 120Hz?
i use a software program to set my crossovers at specific levels to suit my room. I also level matched them with a calibration mic.
@@steadychaosproductions3376 thanks for your answer! But what I meant to ask was how do you have your speakers set in your system, do you have them in small or large with double bass and what crossovers you have them set at? Thanks!
@@the_maxx31 i have them set to small with a 60hz cross over for the towers and 80 for the center
I have an old Polk audio RT 3000 speakers with firing subs on the bottom and satellites on top. They tell me to put the speakers to large at all times , how do you think they will affect it with my DENON LFE
Very good !!!
Hey Steady, great video! I have a
Denon X4500H, all KLIPSCH SET TO SMALL
CENTER RP-504C @80hz
RP 8000F ii @60hz
RP 600M ii @90hz
SPL 120 LFE+MAINS @120
Does that sound about right?
sounds good, though each configuration is often room dependent!
That may be the case with Marantz and Denon but with the Yamaha Advantage AVR's & AVP's that's not the case in my 2 systems ( both Yamaha's). For those of you who have one, and want your large speakers to still play bass here's what you can do:
1. In the Speaker settings select Small then change the hz to the minimum you want your speakers to be. ex. 40hz
2. Then go back and switch the speaker size to large. This way the 40hz is locked in.
3. Yamaha has an eight band PEQ for all speakers and 4 for the subs. The subs can be peq'd down to 15hz provided yours can play that low. You can then go to "manual" and set your frequencies there to your liking. Btw, don't over look the "Q" settings to make sure the timing is properly set or else you'll get some phase issues. Have fun 👍🏼
Hope that helped some of you. Yamaha doesn't get enough credit among reviewers but I stand by the product. Great reliability, sound and build quality.
extra bass works the same way
See here: www.audioholics.com/home-theater-connection/utilizing-extra-bass
@@steadychaosproductions3376 absolutely. I overlooked that most important step. Good call out. Addressing settings part first and then the extra bass is the final piece. 👍🏼
Damn! I just gave you a sub!
Thanks
I'm new to this and just purchased my 1st system. KEF Q550 and Yamaha RX-6VA receiver and SVS PB-2000 pro. What Hz should I set the sub to and the front speaker? Also the front speaker set to small not large right? LFE on or off ?
I'd set all speakers to small, set receiver to LFE, and set crossovers to 80Hz.
@@steadychaosproductions3376 Thanks
Hi, very interesting, what if you set you speakers to Large and use LFE only ? Does that mean no freq are sent to the sub and basicaly will not play anything ?
Cheers…
your sub would only play bass of speakers set to small and below the crossover. Your sub would also still play the .1 channel in a 5.1 or 7.1 movie soundtrack.
But the speakers set to large would be full range, and in LFE, the sub would not get any of their bass.
Yes, sir, there seems to be some confusion. LFE signal never goes to main speakers and "Large" only means full range signal. (small=HPF+LPF, large LPF only) -I use my Denon's "LFE+MAIN" with music (rock, heavy metal) for more low bass, my main speakers are actually large and full range.
Absolutely! I've found there to be all sorts of confusion on the topic.
Nice. I thought it was the other way around, in that subwoofer bass was duplicated by the towers.
lots of people make this mistake.
I have a yamaha rx-v385 receiver. It doesn't give me bass options in the settings. But I have the klipsch 5.1 reference theater system. Theres a low pass knob on yhe subwoofer. Theres a lfe setting on the knob but theres also 40hz- 120hz. Should I just leave it on 80hz?
your crossover in the receiver should be around 80Hz. As for the LFE setting on your sub knob, just turn it all the way to 120Hz and leave it there.
so if I am using front small speakers ,cross over at 80,do I use LFE plus or LFE?
LFE.
Does this matter if im pre amping my main speakers with seperate amp, vs using my avr to power them
It could, depending on speaker size and capability. If you have capable, massive mains and they are powered with separates, running them full band might make more sense because you have the juice to do so.
That said, even if people have the juice, running mains full range is still prb not a good idea as most speakers cant handle frequencies below 40-50Hz.
So what if I have LFE+ mains on but set all speakers to small, or shall I just set to small an leave on LFE only in the receiver an on the back of the sun also
LFE is the recommended setting, using small with traditional crossovers.
What about scenario when u are listening to music on spotify ?
I understand that its better for movies with tracks 5.1 7.1 etc.
But what about spotify I think they have only stereo there ...
Excellent Video. I've Situation With My Marantz SR-5014 Receiver. In My (Speakers Configuration Menu), I Can't Choose 2 Subwoofer to complete 5.2 setup. It Only Allows Me To Select Between Yes Or No. Any Idea Why Would That Be? Thanks.
are there two subwoofer pre outs on your receiver?
@@steadychaosproductions3376 Yes, there is two pre outs.
@@Mamboland so assuming you have both subes connected to your sub preouts on the back of the receiver...what happens when you play a movie? Is only one sub playing while the other one sits idle?
@@steadychaosproductions3376 Hi. Both Subs Are working Fine. I Just Don't See Two Subs In The Speaker Configuration Menu. Not Sure If That Can Be An Issue Later On.
@@Mamboland It just means that the two subs are not 'independent' but the same LFE signal is being sent to both - like using a Y-cable splitter built-in the AVR. Newer AVRs from Denon & Marantz have upto 4 independently configurable subwoofer pre-outs that can be adjusted using Audyssey (or in future DIRAC) room calibration software.
When I run my EQ room calibration it only let's My front crossovers to full range with only LFE. But when I put it on LFE +main It will let me set my fronts to whatever hz I want like 40hz And for some reason the movies seem to sound better with LFE + Main.. My front tower speakers are klipsch reference R-820f series with dual 8" woofers. And I have 1 powered 12" subwoofer BIC America pl200. What would be the best set up for this. Thanks for your time on the video and hopefully a reply lol
If it sounds better with LFE+main, then by all means, stick with it! As long as you're not getting distortion issues etc with your towers. You're towers are set to large right?
@@steadychaosproductions3376 They are set at small. Should I put them at large and test that out as well.
@@TreyWK yeah, if you just set them to small, you wont be adding any bass. Try setting your towers to large only, leave the rest to small. Then, adjust the crossovers on the large towers to set the level of bass duplication you want from your sub.
@@steadychaosproductions3376 Thanks for the information I appreciate it
What about LPF for LFE?
Correct, Marantz is also LFE+MAIN
Is it ok to set LFE higher, 150hz instead of 120hz, I have dual svs sb3000.
yes, you can set it a tad higher, though some say sub localization may be an issue the higher you go.
Great explanation! I just have a question. Should I turn of lpf of lfe setting if I don't have a subwoofer and my fronts are set to large with full band? I built my system with an Onkyo receiver and 5 speakers but without a subwoofer.
My question is whether turning off the setting of lfe would chnage anything in this case as I don't have a subwoofer (so I guarantee that I get all the frequency sent to my fronts), or is it anyhow a setting that won't make any difference?
Your receiver should detect there is no sub in the system, if it does not, then uncheck the subwoofer option.
With no sub in your setup, the LPF is irrelevant.
PS - I'd really recommend you get a sub for maximum impact. Plus, getting a sub will take some pressure off your receiver.
its so confusing.I have I hve Denon RCD -m41 with with SCN 10 speakers.

Newbie here, Cab/Sat, Playstation will play through my sur- snd speakers, but if I select Netflix or Prime, tuner ect I get no Audio through said speakers. Driving me nuts. Any suggestions?
So if you have towers which go down to 40hz and set the LFE to LFE+Mains and set the crossover to 40hz how do you think that would work out? LFE is set to 100hz instead of 120 (person preference) the audio just sounded better. I have Infinity entra 5, center, sub and surrounds with Wharfedale towers (R&L) with an Onkyo NR6050 AVR
depends how your speakers are configured. If you set them to small, then your towers would pass low frequencies below 40Hz to subs. If set to large, your towers would play full range and your subs would also duplicate bass being sent to your towers below 40hz.
I'd recommend you set your towers to small with a crossover closer to 60-80hz. Of course, your true crossover is subwoofer and room dependent.
@@steadychaosproductions3376 I believe the AccuEQ room correction set the to 40hz (RL) which are set to small. The center was set to 90hz and the surrounds are set to 120hz.
@@maze400 40hz is likely too low. Room correction often makes this mistake.
You’re losing sound information if you set LFE below 120hz. Just be aware of that.
I think I'll go with the recommendation from Paul from PS Audio where he explained where if you want the crossover to sound good, at least with music, you should use subs with high level inputs. What those are, from what I gather anyway, are any subwoofers that route the speakers line inputs to the subwoofers to then go to the reciever so that the high level frequencies are, to paraphrase Paul, necked down to something useable and use the subwoofer's crossover settings. And I believe LFE is mostly for home theater setups.
yes, this video is mainly about and for home theater, ie movies.
I’m confused about the LPF for LFE 120Hz, also what happens when you have LFE+Main on and the main speakers are set to small ?
LFE tracks on movies are masteed at 120, so your LPF for your sub should be 120hz.
LFE+main does nothing if your speakers are set to small.
Hello, i have b&w dm602 s3 and asw600 sub. And i have no idea how i should set it up. 😁

For 2.1 channel music listening how much crossover i want to set
Im using svs prime towers and pb 1000 pro sub
I need more bass in music please help
Try setting the crossover to 80Hz and turning up the sub level in the AVR.
I don't get subwoofer support when I choose multi channel stereo, does my head in !
Have you done a 5.1 setup. Thanks.
i used to have a 7.2.4 in my old house, now i just go with 3.2.
It’s not that speaker are not capable it’s more that the speakers sound more full/warm for listening + the subs for doing the low, I know the speakers then do the low in large but I never hear distortion iv had the speakers set to small and played 5-6 movies with big sense and they just don’t sound full/warm like when set them to large. Yes your right speakers don’t do the same as subs will but setting them to full range and also with the lfe channel helps the rich fullness and kick.
So if I set my speakers to 80hz at small and life channel to 120 the gun shots sound okay but when I set it to large with the speakers sets to 80/60 the gun shots and exposition’s go right throw the seats and this is within a marantz 5014 and svs subs with mini dsp with bowsers 603s htm61 centre. But also when u go separates what’s the difference then in what setting u go ? Looking at upgrading to separates to find out
If I play Aquaman at loud levels, my Pinnacles will distort if set them to large, specifically When Aquaman fights the beast thing to get the golden staff.
but if it works for you, no problem, its just generally nor recommended.
@@steadychaosproductions3376 that is one movie that iv notice to , have to set them to small for it
If your L & R speakers can handle low frequencies, would it sound better if the bass is "doubled" using LFE + main?
it would certainly add more overall bass and low end.
@@steadychaosproductions3376 I guess my follow-up would be: does having LFE + Main on without any speakers set to large do anything?
@@shawnmathew825 If all speakers are set to small, then no, LFE+main will do nothing.
@@steadychaosproductions3376 thank you!
Well, you also should explain that low frecuencies need amazing amount of power, so when you main speakers reproduce 20-30-40Hz, they need too much energy, taking that energy from the AVR, and even when the AVR is sold as 7x100w, actually that amount of power is only for 2 channels at the same time, when a film use all the speakers, the real max power is mch lower (maybe 7x50w). Making you speakers free of the low frecuencies, you are able of raising your volume much more if you only have an AVR and not and extra amplifier for you main speakers.
Hi,
My towers are 45Hz to 20kHZ.
Can I put my crossover at 60HZ?
you could, experiment with it and see what sounds best to you.
I only have 2 towers do I need a sub to change these settings?
Yes. With just towers you'd set your AVR to LFE and your crossovers based on your towers' rated frequency range.
You could put your towers at full range or full band if you wanted to depending on the type o towers you have.
I think one important thing to mention here is that LFE plus main does not mean that the LFE channel is sent to the mains. I highly doubt there is any 20 Hz signal being sent to your LR speakers in a movie or music, therefore your main speakers will probably never be asked to play 20hz.
depends on the movie and mixing. Varies.
What I don't understand is why I have no subwoofer on my multi channel stereo. Only had this issue with denon , my yamaha and sonys included sub on multi channel stereo.
All my speakers are small , 80hz . Bass management lfe.

@@iansteventon4221 i do like my denon, but i will say, my denon's Audyssey calibration absolutely neuters my subs. Have to adust them manually.
@@steadychaosproductions3376 I've found not using any audyssey equalizer has brought back my front stage back to life.
It was totally missing with deq and dv enabled.
Done some research last night on the forums.
Theirs a good avr in their somewhere but I'm going to have to work hard to find it .
I ran my calibration once with my previous sony, I'm doing a calibration every week now 🤣 !
Atleast I've found the culprit, deq.
I dont know why bose manual recommending to set all satellite speakers to large. Do u have any idea
no, but that's a terrible idea.
If the Bose has a bass box (Acoustimass) running small cube speakers like their old AM5 system did, then they’d need a full range signal running from the AVR because the Acoustimass box has its own cross over settings.
Whats LPF for LFE?
low pass filter for low frequency extension.
Thank you so much for the vid! I have 2 towers that I really only want highs and kids sent to. I also have 2 subs. I have a denon s54bt. I have my towers as "fronts" and set as small. Is there any advantage to use LFE + Main? Would that send any additional signal to my subs since its "removed" from my small speakers? Thank you in advance for any help!
if you select lfe+main and set your speakers to large, then any bass below the crossover point set for those "large" speakers will be duplicated by your subs.
I wouldnt recommend this. Setting your towers as small and using just LFE is the recommended option.
@@steadychaosproductions3376 Does setting to small and lfe+main have any added bass for a dedicated sub? Doesn't seem like it, but wanted to make sure...
@@CC6_Fanclub_President no. If the speakers are set to small, then a crossover would be used anyway, meaning anything below the crossover for a given speaker would be diverted from said speaker and played by the sub.
@@steadychaosproductions3376 perfect! Thank you so much for the reply. Learning my way into better home audio. I just bought a crown xls2502 amp and an Art Cleanbox Pro to help push it. Never ends, lol.
Clear but not clear. My main towers can go to 40htz. Denon calibrated Center and front towers to Large with crossover at 40htz. Changed it to small and crossover to 80. And in Base management it's just LFE at 120htz.
But in my listening area speakers sound bit better with 90htz crossover for music and 80 for movies.
Would you still recommend to change just base management to LFE+ Main?
ideally, you should just use LFE and set your speakers to small. If you have massive, hulking towers, you could use LFE+Main and set them to large, but said towers would need 10" kickers in them for it to make sense.
