Why Go Dual: Benefits and Placement of Multiple Subwoofers 

I will be adding a 16 ultra to my current setup... after testing and reviewing multiple brands of speakers and subwoofers, I have attempted to illustrate effectively that SVS simply does not compare to any brand of audio equipment at the price point while maintaining the most clear, crisp, responsive and detailed sounds in any applocation you utilize! Not only are the subwoofers extremely high quality over any other brands out there, they seamlessly blend music and film audio better than most $2000 and upwards costing drivers. This can make the biggest difference in a 4k home cinema application where music and movies are played. I have used valodyne subwoofers for years and even their most expensive products can't come close to the sound the SVS woofers produce!

I actually bought my second PB 12 Plus sub from Ed late last week and must say Ed was a HUGE help with all the questions that I had. Great video and looking forward to many more from you guys....also nice to finally put a face to the name :-)

Great video. Simple and to the point.

I got 2 subs, but I have them both in front. There is no practical way for me to place them any different than that. They still sound great. Big difference with having 2 instead of 1.

Dual subs is essential. It makes a huge difference. You fill the placement location sound. It’s amazing.

I totally agree, for years I have a sweet spot (left side of the couch) for the LFE effect. By adding a 2nd sub woofer took the dead spot out. Now on the right side of the couch have the same LFE effect as the left side of the couch.

Thank you guys for putting this video together. Very insightful! I've been hesitant for years to go dual sub since I worried it'd be *overkill*, but after getting a better understanding of the benefits of going with such a setup, I'm less worried. Yes, it'll take a bit of time for tweaks to nail the sound output just right between the two subs, but I'm sure it'll be worth it. I'm legit looking forward to finally getting a dual sub setup going and enjoying the benefits y'all outlined in this video. Cheers!

ED is the best,so helpful.I talked to ed a ton for subwoofer question's.The guy is down right wonderful.U guys at SVS rock.

Fruitful demonstrative information. 👍

If I have to run one sub wireless due to room placement at the rear, should I run the front sub wireless as well? I assume its not ideal to mix wireless with wired.

Ed Mullen is one of the best in the business. Super knowledgeable and a class act.

Just picked up a 2nd SVS sub rather than upgrade from the SB1000. I’ve never heard a single sub sound so good in a decent size room with vaulted ceilings. Have run it hard for years… SVS is also top notch in customer service. Once they replaced an amp under warranty…no nonsense and sent next day.👍

I went from two subs to four recently and got as big as an improvement as I did from one to two.

I recently got a sb4000. I love it. Definitely thinking about getting a second one.

Can't wait to go dual

Excellent explanation. Thank you.

Got a new SB12-NSD for a steal and would love to goal dual for more even room response. One factor you guys forgot to mention was cost, adding another sub is too much for my wallet right now. Great video!

How about 1 floor standing and 1 in ceiling 300w subwoofer at opposing corners? Would that be an optimal placement?

I’m so torn. I’ve had my p3000 for 8 months and loved it at first. It’s really good for movies in 3/4’s of my 3000 cubic room. I do want more pressure though for scenes that have the ambient type of pressure. My other problem is my klipsch bookshelves really fall off at 100hz in my room so I run my crossover at 100 and it’s a fuller sound but the bass isn’t as clean of a sound as when it’s crossed over at 80hz, if that makes sense. I know I need to go duals and will but I’m wondering if I should just trade up to the pb4000 now instead of ordering a pb3000 which could potentially lead to more hassle having to send 2 back. Gain and sub is set at -10 and the Yamaha avr sub setting is at -1.5.

What is the name of the surround sound in the beginning of the video?

2:13 could you be any more optimistic than perfectly aligning the peak and null so that they cancel. Most of the time these won't overlap in this la la land way, and thus typically drop the peak/null by about 50%. Sure you can move them around to find the spot, but one sub might end up in the kitchen.

should both subs be set up exactly the same? e.g. should the phase be reverse for one and normal for the other?

I have got q accostics 3070 is that a good combo With svs pb1000 pro. Normal sized Livingroom

The selection of subwoofers and sound bars for great and Hugh normous

Could a Dali e-12 and e-9 be dualed together anyone with a Dali 5.1 system thanks

Really great video! I have a rectangular room, its about 7 meters wide and 3 meters deep. i am sitting in the middle of the room looking at the TV from about 2 meters away. My front speakers are on the far right and left side on the 7 meter length. Where would you recommend to place a dual sub system? Right now i have a single SVS sub between the TV and the left front speaker.

just picked up two sb2000's for a 2-channel system in a dedicated listening room, about 14x22. i have tried several configurations and i can't seem to get what i'm looking for. my magnepans respond well down to about 47Hz, all i'm trying to do is re-enforce the low low end without smearing the mid bass of the maggies. is it worth returning the sb2000's and buying a single sb16 ultra or would i be spinning my wheels only adding more mushy lows and wasting more money?

Excellent video. Got a question though I'd like to setup a 7.2 arrangement with the speakers I have. I own 2 subs, different sizes though and the diagonal setup you mention is feasible for my space Should the larger sub go up front or in the back?

That is one sweet setup wow

I just added a second SVS Ultra 13 sub to my system and then did the amplifier upgrade kit Well worth the additional investment

i have two pb13 ultras behind the seating area

You are better off with 2 svs lower line subs then 1 higher line svs subwoofer.....thank me later!

How big is that tv at 0:37?

I'm stuck with 3 passive subs and one amp. How can I make use of them all? How must I go about connecting them?

Thanks for clarifying that.

Currently using SVS PB1000 sub, want to add SVS PB1000 pro as dual sub............... Will they synchronize well?

Is it ok if you have dual subwoofers that cost more then the front L&R Speakers? or should you rather upgrade the front speakers instead? Thanks.

my receiver Sony STR-DN1050 has two sub outputs but only has one calibration/configuration for a single and not dual subs. Do I just run the auto calibration with both subs connected or just one connected? I'm confused because if both subs are connected (both rca out on receiver to the LFE on the subs) and I run auto calibration how will the reciever know which sub to set the distance and db for the sub?

I have a 5.1 system running Ascend Acoustic speakers with a PC12-NSD, and while the system does sound good at some points in the room it is lacking in some points of the room. I just bought a PB12-NSD and will be placing it in the opposite corner from the PC12-NSD. Even though one is a cylinder and the other is a box, I have heard that the sound is virtually identical so I am hoping this setup should even out the bass throughout the room. Is there any tips you guys could give me on getting this setup properly?

Hi, if I was to place a second sub behind my seating position, are there issues with running a cable just over 10m (33 feet). Will the signal still be strong enough?

I have the old pc13 subwoofer. I want to add another one to make a dual subwoofer. What subwoofer do you recommend to match equally with my pc13. And do you advice putting them diagonally on each side for best performance?

In the process of buying subs for my theater room 16x13. I’m thinking dual PB-1000 because I feel like dual PB-2000 is overkill for the room. I’m also running B&W CM8s and a B&W Centre. Would pb1000 be fine?

When two subs are placed facing each other like showing in 3:58 in the video,doesnt that could cause a phase cancellation and other issues?

So someone can tell me, if you have one sub on 40% gain, two equaly subs with 30% gain can produce more sound and bass than one over 40% gain?

I have a polk audio psw505 what's the output difference between that and a svs pb 2000 . I have klipsch r28f loudspeaker after 54 of 74 on my reciever with music the polk won't go any louder and the towers start over taking the polk sub and all I can hear is mids and highs. I've tried cutting down the gain in case I was over working it . didn't help it just doesn't have enough loud volume output.

If u have 2 subs in front do u leave both at 0 phase or have one at 180?

How to connect dual subs when your reciever only has single sub/LFE output??

has anyone tried stacking 2 subs? I have read in other scenarios where this immediately gave a flattened response...as the wave lengths would not be able to reinforce themselves...perhaps I'll add a sub and try some tests with different heights as well as different locations.

We have a hugh bass on cement. Is there anything we can do in this room to stop the big vibration in our house and neighborhood? Our son built a new theatre room off the house and the bass is intolerable, but on cement slab. Thank You.

If I go dual, would I calibrate them to each put out half the output required from my single sub?

I have a JBL Studio 2 Series setup(290 floors, 235c center, and 250p sub). I want to add a second sub. The 250p is no longer manufactured. The closet alternate I can find is the Klipsch R-110SW. Spec-wise they are very close at 10" each. The 250p is rear-port while the Klipsch is front-port. Do you see any problems mixing these two subs? Thanks in advance!

When you speak of dual subwoofers, do you mean each subwoofer plays the same summed mono input or is one subwoofer stereo-left and the other stereo-right?

SVS, what about one sub at the center below the tv and one at the back center?

what about both each 1/4 wall lenght behind ?

is having two different subwoofers from the same brand a good thing also?

Say you want to add a dedicated subwoofer to a soundbar that already has a subwoofer buit in. Does this count as a 3.2 audio setup? And is it recommended?

Should the subs be a matching pair? Should they be the same brand and size? Can I do a 12” with an 8”?

Good knowledge for placement of dual sub.

What about a 15 inch subwoofer with a 10inch sub or does it have to be atleast 12 to 15 inch dor the second?

What about using two different subs, like size/brand/model? Also, what about using a wireless sub kit on one sub and hard wiring the other? Do these things negatively impact the results? I have one 15” now and adding a second one diagonally would impact a walk way. A 12” could be more practical.

i am planning to go dual and while i would like to place them optimally at opposite corners i will probably opt to do the front of room placement for same reasons as discussed in video. i know every setup is unique but in general is putting them inside of mains or outside of mains...is one better than the other?

Would two PB1000 be better than one PB2000? Could they get as low as the PB2000 or would frequency still be limited by the size of the individual subs?

What about placing them in the back ?

If I use the y splitter would it take power away from my other speakers to push out to the subs? I would be using two Polk psw 125 with 4 Polk monitor 70 tower speakers,csi A4 center and two klipse book shelf. Running with a pioneer vsx 1020k. Would it still work well?

Are there any advantages to having multiple SIZE subwoofers in a room? I currently have a 15" and a 10" (in opposite diagonal corners). It definitely helped with adding more bass in the HT (which would be obvious) but do you think having the multiple sizes helps with actual frequency, range, response? Reason for asking... I have considered adding a 12" or possibly going with dual 15's in the front and dual 10's in the rear.

This guy is so articulate. I need to read more books

What will be the total sound system price?

Good stuff!!!.. Larry

svs subs are amazing

Hi, I currently have a PB3000 and would like to add another sub. The problem is,I only have space for either a 2000PC or 4000PC, would this be a problem ?

Is it important for subs to be out in the open/unobstructed or can they be hidden (like under a bed)?

If my av has two sub outputs can I use 4 by using Y splitters? Are there going to be problems? Like, I mean, the signal only has 50% of it's "strength" remaining because of the splitting.

Is one sealed sub and one ported sub a good idea?

I have 2 pb2000s. Both are in the front next to my floor standing speakers. Both at 50% gain but when I run audyssey it always makes me match the right one to the left one so they are both at 75db. Is this normal? Basically why is my right sub weaker ?

If you have two subs are they producing the same signal in the mix....or are they independent from each other?? no one seems to mention this detail.......

would you gor for dual sb-1000pro or one sb-3000pro.. ? price is about 1:1 here. Quite big livingroom/open area, mainly for music use (~90%), but also tv/movies

I run 1.5 1 speaker and 5 subs.

For mainly movie watching on projector in basement media room, if I go with 2 12" subs, do you recommend ported or sealed? Size does not matter necessarily. Room is 17x30

Is it better to have a ported and sealed as a pair or should they be the same, also is there any benefit if you can only have side be side placement?

Damn! Just installed my two SB-1000 Pro and my god does this make a difference in my room. I'm speechless.

Sir how connect two subwoofers in my Samsung 5.1 Blu Ray player

Let say i don't have any room EQ / bass DSP whatsoever, are dual sb1000 going to be better than a single sb 2000pro ( in which it add bass DSP ) ?? my usage is like 50% music and 50% movie / gaming thx b4

Nice , do they need always a cable when you use 2 subwoofers

Can I pair my pb2000 with a new pb3000? I can t find any new pb2000 now! Thank you!

I run 2 subs. They are mismatched so it took some finagling to get it right but it sounds great. Especially for music. My next upgrade will be 2 matching subs.

Hello! Please tell me, I have two SVS PB-2000 pro subwoofers, I want to set the correct parameters in the application, but I don’t understand much, so I would like to ask two questions. 1. Is it possible to change the settings in the app on two subwoofers at the same time? There is a problem adjusting one when both are playing, no change can be heard 2. maybe there is a video explaining what the tabs mean and what they affect. 3. I have a dali opticon 8 front, - what sound parameters would you recommend for your subwoofers, small or large speakers? 4. how much to put the crossover on the speakers and subwoofer? I have a Denon AVC-A110 amplifier. Thank you in advance!

When I went from 5.1 to 5.2, I found that the LFE now have much more direction, in a good way. So when for example, the lighting strikes. It's coming from 5 o'clock and high (or wherever), rather than all around like it used to with just one sub. It's like the dule subs allow the other speakers to do their job in setting up directionality for the LFE. It's very noticeable to me. Is that possible or am I hallucinating?

So doing opposite corners is there an issue with having the front sub outside the front speakers as shown at 3:48

If my onkyo receiver is 7.2 it can play sound on 2 subwoofers? I'm new to this. Now my subwoofer is using the subwoofer output. The Pre Sub output is for a second subwoofer? THX

What's about using your subwoofers for music? Are they made for home cinema only or can you enjoy then with music just as much as with movies?

Would two sb 2000s be superior to one sb 4000?

Will a svs sb2000 sound ok with a 3000 or should I get another 2000

What are the issues/cons of have 2 subwoofers of different brands/sizes/power?

Hi, I have 2 rooms with 3 sealed subwoofers (Definitive Technology supercube sc6000 1500watts and two sc2000 650watts/ea; each box has 3 speakers) of the same brand and series, just different sizes: 1. Family Room has a 10 inch subwoofer in a 5.1.2 setup. A Denon AVR-S750H receiver that has 2 identical subwoofer outputs. 2. Projector room has two identical 8 inch subwoofers in a 5.2.4 setup. A Denon AVR-X3700H receiver with 2 independent subwoofer outputs. QUESTION: I want to buy a 2nd subwoofer for the family room to become a 5.2.2 setup. I can't buy a second 10 inch subwoofer because it's disontinued, so a 2nd subwoofer will be 8 inch. Which option below is best or would you have another suggestion? A. Because the projector room has the Denon AVR-X3700H receiver with independent subwoofer outputs, I was thinking of equipping this room with one 10 inch and one 8 in subwoofer (same brand and series, just different sizes). One would be located at the front right of the room, and the other at the back left of the room. B. The family room with the Denon AVR-S750H would have two identical 8 inch subwoofers. One would be located at the front right of the room, and the other at the back left of the room. Thanks.

I've a 10in front facing sub and I'm considering adding a smaller downfiring sub is that ok to mix subwoofer types?

I would like to add a second sub for a music stereo system. I had 2 subs before and had them set up in opposite corners diagonal. My seating area is closer to the front wall within 5 feet to the monitors and the front sub. I do understand adjusting the phase of a second sub in the back corner but how would I get the timing right with a second sub in the back corner ?

I really want to go duel, only problem is I have a klipsch rw 10d sub and they don't sell does anymore. Would it be a problem if I bought another (newer model) Klipch to match the one I have. Or would that be a disaster. I'll won't mind if they visually don't match a 100% btw.

I hope this isn't a silly question but does it matter if anything is in front of the subwoofer? Putting the sub in the corner behind a sofa?

How would this work with two SVS 3000 *micro*?

I have a question, how much did the whole set up cost? I don’t mind if it’s above budge! I’m looking for a reallllly good theatre system that’s actually worth it!
