What is the forums opinion of SVS subs?

I went to a commercial audio seminar in the mid 70's where Altec was demonstrating their new line array (stacked subs) for commercial installations.
To this day I get goose bumps when I think of the sound I heard during the several days of that meeting. It was set up in a ballroom of the hotel and I swear it rocked the entire building. It was a four channel system with 33,000 watts of power into very efficient Altec drivers. They were using a four channel mix down from the original tracks for Neil Diamond's "Love At The Greek" live concert album.

Unfortunately, I was never able to incorporate what I learned there in any of the commercial systems that I built, but the concept has stayed with me all of these years.

Being retired, I now have a house with a good sized room for listening to music (15'x46'x8').  I wanted to try the concept of the stacked subs that I heard so many years ago, but I had to stick to a budget. I started with two of the SVS SB1000-Pro subs in order to check them out. I was happy with the basic construction, the sound, and the easy set-up via the SVS app, (and the cost). So I added a second pair and started my stack of subs. After a few months I added the third pair to the stack.
Each pair I added gave my system an expanded sound stage, better imaging and a a more rich, fuller and detailed sound. I've been listening to this set-up for the last couple of years with no issues with the subs.

While the SB1000-Pro subs from SVS have both high level (speaker level inputs) and single ended low level inputs, I decided to use the SE inputs to feed them.

I feed the mains through the balanced output of my DAC. From the single ended output of the DAC I feed a separate pre-amp which in turn feeds the subs.

I'm sure the sound of the music I'm listening to wouldn't satisfy the most discriminating audiophile out there. But WOW, it has certainly has increased my listening enjoyment way beyond my expectations. (All for less than the price of one of the top rated subs.)

I have been using a 1/3rd octave RTA left over from my commercial audio days to set levels and to check overall FR of the system as I have it set-up and am pretty happy with the response at the LP in my room. I had a peak at about 100hz but have been able to even that out using the PEQ built in to the DAC.
I'm currently learning REW so that I can see the response more accurately.
The experimentation has been fun, and the learning continues...
But there is always the question... what would a fourth pair on the stack do???

I’ve had a used SB2000 in my home theater for 7 years or so and have never had a hiccup or problem. This is the first I’ve heard of SVS products having problems or any criticism of their customer service. You could also look at the Rhytmic F12 that’s just a little more expensive than the SB3000 but is by all accounts excellent and probably even a bit better than the SB3000 overall — they’re about the same size but the F12 goes down to 14Hz (-3dB) and weighs about 10 lbs. more FWIW. The downside is that they don’t offer convenient integration software like SVS so it’d take more work on your part to optimize them for your system, room, and tastes. Always trade offs.

@jac616 Interesting setup.  Have you tried just using four subs in the four corners of the room as like in a swarm array?  Would be interesting to hear if there are any any improvements (or not) through any added room node cancellation, evenness, etc.

They are fine.   Key with subs is know what you need and get the right one. 

Hello all.  I read all the responses in this thread and need guidance.  I have a HT set up.  I use it for two channel music, multichannel music and movies/tv, in that order.

After 20 years, my Velodyne (1250  watts RMS ) sub blew yesterday and I’m looking for a suitable replacement.  I have B&W 804 speakers and a  B&W CC speaker which are driven by a Rotel Power amp, 200w x 5.

My room is 14 ft. long by 12 ft. wide.  I use Anthem’s ARC Genesis room correction software.  It works great.

My dealer carries a full line of both REL and SVS subs.  Looking for thoughts and recommendations from this group.  I’d like to keep the cost around $2K.

Thanks!
