Why Go Dual: Benefits and Placement of Multiple Subwoofers

SVS Director of Technology, Ed Mullen, discusses how running two or more subwoofers increases headroom, smooths bass response throughout a room, reduces localization and provides unexpected benefits compared to a single subwoofer.

You'll also get tips on the most common and optimized room placement for dual subs and advice on improving your home audio system's sound quality.

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!

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

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.

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 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!

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.

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 :-)

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

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

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

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?

[markubiak]

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!

[hideff]

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

[marcfavell]

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

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

[DCUPtoejuice]

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.

Wait til you get 8 subs! One in each corner on the floor and on the ceiling. Whoa buddy!

[ericnortan]

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.
