Are stereo subwoofers better?

[@gbaker6478]

If you have seen Top Gun Maverick in theaters you know that it matters. As they take off to go to the target one of the jets throttles up on the left side of the room. As it takes off propelling down the runway it literally rips right through you and goes out the right side. So worth it to experience that.

[@Joshualbm]

There are definitely audible cues in the 60-40hz range, where many subs cross in. but even in the lower frequencies, 30 on down, there are left and right channel differences. Problems with cancellations and or peaks are more likely with a single sub because the bass coming from the speaker that is further away will not have the same phase relationship as the one closer to the sub. Much of the fullness of a soundstage is created by the lower frequency instruments and ambient reflections, depending on the recording environment. Anyone can measure this. Just play the left or right side by itself and you'll hear that each speaker is getting very different levels of bass.

[@psicoterapiavinil3566]

Subs from REL has Speaker Line levels. The Sub is connected in the same output of the main speakers.

[@eggshellskullrule7971]

One more benefit in stereo subs. I do run stereo subs only coz I use my pair of JBL4320 which have 15" woofers each. I cross them at 120 or 180 or 220 Hz with active system. So it actually relieves much of the workload from the woofers in the "satellite" (main) speakers on each side. So when I run some speakers, e.g. AR5, The Advent Speaker (Large) etc., not only do I get deep bass, but I also get less distortion and higher SPL from the main speakers. When we use one sub only, we tend to cross over at much lower freq points to avoid the faults in stereo imaging due to the more apparent left right stereo span between the two main speakers. That way, we might be forced to run full freq range from the amp to the main speakers. So in relative terms, the benefit of running stereo subs lies also in better sound overall coz now, crossed over at higher points than 100hz, the main speakers will sound better under less load in the mid bass which is now taken by the subs.

[@nissimtrifonov5314]

The "main speakers" have been designed to produce whatever frequency range that their spec sheet states. So you are not "doing them any favors" by rolling off bass frequencies that they are capable of producing... Paul said that in another video

[@eggshellskullrule7971]

@@nissimtrifonov5314 : I'm sure you have a good reason not to run subs the way I described, and on the other side of the coin, I already traded the balance. Actually, it wasn't so much abt using the natural roll-off the main speakers had to offer, as abt the quality and thus the effect of the active filtering device would put on the system as a whole. I mean if you use lousy active (electronic) xover devices, those opamps inside those devices surely are not gonna give you clean filtred output to the main speakers And therefore it will be of paramount importance to use a good active xover device in order not to eff up the sound trading for deep bass. Right?

[@xanderguldie]

@@nissimtrifonov5314 The roll-off is exactly why a sub is useful. The spec of the speaker may say it starts at 35 Hz for example but it probably starts to really be good at producing sound from 50 Hz. By matching the speakers with a sub you can set the point of crossover.

[@cp070476]

Always use 2 subs.. One for left and one for the right because if you are like me you have the subs set to 'Direct' which is 200hz and above this becomes directional.. This gives dramatic impact to low vocals and drums which your main speakers aren't able to reproduce. Subs are vital!

[@nissimtrifonov5314]

They teach mixing and mastering engineers to make sure the low end is always mono. Kick drums and bass instruments should always be in the center, pretty much any engineer will agree with that. There are even tools designed to remove or enhance the "side" signal, which is information in the music which is not the identical in both the channels, and a popular setting is to make everything below ~100Hz mono. In other words you can have stereo subs but most of the time they will be getting the exact same signal. Special effects in movies might be an exception. There is, of course, the other reason to have more than one sub, which is that you can get a more even distribution of low frequencies across the listening room that way.

[@footedroot]

Do mix and mastering engineers still do that? I heard they make below 100Hz mono in the days of LP.

[@springermusicnet]

again, it depends on what you are doing .... original source all the way to the room and level played back... recording an orchestra or band live is different than on a board, or hip-hop vs. classical vs. jazz, etc. Small room vs. Large room also makes a difference, as well as listening area

[@linkeddevices]

wow this is like 50 years outdated from the days of LP and when we'd have to put two spaces after a period. the reason why they would teach that is to prevent the needle from being kicked out of the turn table. nowadays especially NOW and with upcoming ambisonic audio there's plenty of music with LF that doesn't down mix to mono till like 35hz. and then not everyone listens solely to EDM and hip hop.

[@jonlsl]

Yes I agree stereo subs using proper R+L inputs to the subs... Because some music are mixed and recorded in away where the phase differences between the left and right are purposely manipulated to give the listener a certain effect and u need stereo subs also because u get to hear the effect of different mic set ups for different locations for certain recordings.

[@mjot2360]

One sub (REL) dialed in correctly will blend seamlessly given you have speakers that go down to 45HZ or lower. When using bookshelf speakers, it makes sense to run stereo subs as the subs must be crossed over at a higher frequency. A single sub will become more directional when paired with small speakers.

[@janinapalmer8368]

Good answer Paul... you made a very good point about the LF sound pressure changes... this really does happen too, but there's still this inevitable draw back and that is .... when the two subs are radiating the SAME frequency at the SAME amplitude then there can be and often is wave cancellation with the room. I must stress here that the bigger the room ( ultimately ending up as outdoors as an environment) the less likely this cancellation becomes

[@AnOriginalYouTuber]

I tried two DIY subs. Despite most of a mangy dubstep I like has mono bass lines, I'll never go back to using a single sub. Bose was wrong about low frequencies. Even the best subs produce higher audible harmonics. Its easy to spot where the bass is from. The subs are tuned to 25Hz and bottom out at 12hz and are physically adjusted to be in phase with the mains. IMAX and Dolby Atmos theaters can't compare.

Stereo subs do offer some advantages under some circumstances. However the chances of your subs placement near to your speakers being the best locations for low freq room response are near zero. There for, for 95% of us placing dual mono subs in the best locations for bass response/room issues is by the best choice, giving the largest gains in sound quality. Most people dont want to hear this because it's not a sexy as "stereo subs".

Two smaller subs are always better than one big sub. And you can even go more than two and spreading them along your front wall, because the more you have the more even the bass response in your room will get (generally speaking anyways). And playing all those subs in stereo or in mono ain't that important, the important rhing is that you are spreading it out.

I guess my question is, since I'm running a Home Theater receiver should I just use the two RCA Subwoofer outputs? I eventually want to run a Stellar PS Audio Stereo Amplifer from the Denon Right and Left channel pre-outs to power my mains. Until then how would I connect my subwoofers without using the LFE inputs? Should I want to connect them differently in my dual purpose room? I have a HSU Research VTF-2 MK5 subwoofer and plan to buy a second. The receiver currently sets the crossover frequency on the subwoofer and I set it to 90 hertz.

[@Sentie77]

I have just a hint for you. when you install the subs in the Denon configuration wizard and define the crossover frequence @120Hz, your High output to the speakers are nearly cut off, while the stereo line outputs are still funn range. So if you do use the sprout for your main, be aware, that they are full range.

@@Sentie77 I did try powering my mains with the Sprout100 a while back, but it didn't work.

Not needed. But it wil decrease overal sound quality to that of the worst sub. If Sub A is sealed and sounds punchy, and sub B is ported but muddy. Your overal sound will sound muddy. you could set two crossovers. down to 40 Hertz on the sealed, and then let the ported take over below that (if it goes that low). Good reason to use two subs is to make the bass more uniform. So if your main goal with the subwoofers is home cinema any kind of properly placed multi subs are great. Because more seats will have that hous shaking bass. If sound quality is your goal, get one good sub with your budget and cross it over at 80 Hertz. (this is when the sound becomes so omnidirectional you will have a reeeally hard time telling where it comes from).

I disagree with the idea that you cannot localize low frequencies.... Yes they may RADIATE ommnidirectionally, but I've always been able to localize my sub... in a general sense. In my living room system, I currently have one sub off to the left, and it pressurizes the room unevenly. I have run dual subs, and they pressurize the room more evenly. In my other family room, I run stereo subs, and it's the best. I can make them mono, and certain music feels less wide and spacious. It greatly depends on the recording, as to how much stereo information exists below 80 Hz, but any orchestral music will certainly benefit from stereo subs.

I disagree for another reason : almost all recordings are mono for frequencies under 100 Hz . So any pressure differences between left and right will be almost always non existent . The reason for this is that low frequencies are very taxing for the woofers (high mechanical excursions wich can lead to damage) : spreading the load across the available surface of both woofers halves the necessary excursion. Even if the recording engineer decided to record the sub 100 Hz spectrum in stereo , it is still a good idea to sum the signal to mono , even if you have 2 subs . The small benefit of having a nearly non existent stereo image below 100 Hz (too big wave lengths vs room dimensions) is not worth the risk of destroying your subs .

[@krishollerday8812]

There are a couple of other ways to utilise two subs. You can put them side by side, or one on top of the other which couples the low frequencies and increases the SPL from them higher than if the subs are separated left and right. Or if you use sub models designed to operate in cardioid mode, you have one facing forward and one facing back which creates cardioid pattern low frequency sound out the front, and nothing at the rear. Very good for better controlling those low frequencies in a small and or difficult rooms. Personally I use two Yamana DSX18 subs crossed over at 100 HZ, in extended frequency mode (down to 30 Hz) and set up in cardiod mode for my small 16' x 25' lounge. I'm fortunate to be able to have the rear of all speakers 7' away' from wall. The cardioid subs have really cleaned up the low frequencies compared to using just a single 18" sub previously!

Aside from the method of using the speaker level outputs mentioned in other comments (which is the recommended method in the video) the Sprout100 has stereo RCA outs that are volume controlled. You can run one each of these to a sub and use the low pass filter in the subs. This is mentioned in the video as more of a back up plan, but options are good to have.

I reckon 'time' is the problem: the low's have to arrive at your ears at the same TIME as the high frequencies, that's why -without (digital) sound processing- the low frequency speaker has to be located at the same distance to your ears as the mid and high frequency units. The same 'problem' counts for the reflections of the speaker units. That is why i always laugh about Bose, the company that claims you can put your sub 'in the neighbors garage' without sonic problems.

Yes but I am still waiting for the right answer. LOL! How do you do this for 50 years and not know how to set up 2 subwoofers and take advantage of the true benefits of having two subs. There is no left and right when 100hz is 11' long especially if your room is only 16 feet wide like so many. Serious people who know about sound wrote about this decades ago and there is no mystery on what to do, only measuring and delaying. So yes repetitive and wrong. Maybe on the 4th try we will actually look at this simple issue with some free software and a $60 microphone. No excuse for passing on misinformation like this. Oh and I forgot 2 channel people still play records which are mixed to mono in the bass anyway. :(....c'mon 30 years of the internet and we seem to know less and less!!!!

@@JurMalafi Maybe you can provide the "right" answer then. You seem to know it, but prefer to rant and bash instead. Your comment is hence not all that useful (I know, it's yt comments so story of our lives but..) . The main point should be to help other people out, i think. Peace !? :)

@@entity279 Just Google, why do I need to explain it? I gave you 2 VERY good reasons stereo subwoofers is a ridiculous concept, particularly if you play records. If you are curious, there are many peer reviewed articles with pictures available for you to read and digest. Save yourself the time of reading in a forum, seldom is the right answer presented. Harman has multiple sub studies, Earl Geddes, Klein & Hummel.... that's how I learned about multiple subwoofers, I read the research. and then I spent $150 on software and a microphone to calibrate my system (every room is different). Best money I ever spent. This is not a place to teach room acoustics 101 and how low frequencies behave in small rooms. :) but the information is out there and should be easy to find.

[@entity279]

@@JurMalafi Hmm but if the premise is that one already has two subs (due to the way the question was asked). Why not run them in stereo configuration then? Even if there's little benefit. There is some, sometimes at least.

he emphasized the word "augment" like he was trying to piss me off because i always say don't use subwoofer as an augmentation. eh... not very interesting subject anyway.

[@Invictus96vid]

Since subwoofer users are usually attempting to increase the level of bass notes, augmentation is exactly the word to describe their use.

[@ped-away-g1396]

@@Invictus96vid he emphasized the word... twice. and as far as i know i'm the only one around here that is against the use of subwoofer as an extension/augmentation and i said that out loud a lot of times... and everywhere too. i don't know if he was trying to piss me off or not but he clearly emphasized the word for some reason.

[@mornecoetzee735]

I am sorry but subs have no place in a stereo system, if you need them you are either a bass head or you have poorly designed speakers. They colour the sound and I have yet to see an implementation where they sound natural.

[@ped-away-g1396]

@@mornecoetzee735 because all the subs on the market are designed to be an extension, not an integral part of the system as they're supposed to be (passive subs are exceptions, kind of). subwoofer is not about the amount of bass, it's about work assignment, assigning each driver to the work they're best at. and for a subwoofer, is handling all the heavy excursion, letting the rest have the headroom they're supposed to have and minimizing intermodulation on the woofers. it's about working smart instead of working hard. if you want the sub to work well, the entire system has to be designed with the sub in mind in the first place. the entire system needs to be actively crossed over (and properly) or you end up with the passive crossover or band overlap messing up the sound all over again. all the speakers also need to be the same type too. you see, there's a stack of requirements to be met. with the virtually infinite choice of equipment out there, if you don't know exactly what you're doing and just keep mixing things together, you'll never get it right.

Bass is omni-directional.

[@tommethans7827]

Take the sub money and buy new speakers. How old are those audionotes? You can buy speakers with a very small foot print

[@jeremyphilander8833]

I might disagree on stereo subwoofers. Subwoofers are omidirectional. Placing 2 in a room might cancel each other out.1 is enough mate. Just buy a big one.
