Bought the wrong subwoofer!

I Sold the SVS yesterday. Going to pick up a Rel Britannia b3. 

"Going to pick up a Rel Britannia b3."

That's a 15 year old design when the company was R E L, not "REL."

Completely different  company, with different direction.  . Part of the last lineup  when it was still  made in England.

I use 2 B3's. They do the job, but are a different animal compared to the current "REL." 

Hopefully, you are aware if it has a problem, you're SOL, as REL does not handle issues with R E L products.

for 2 channel music, don't but an SVS. The Rel is a great sub for 2-channel music, but for 1/3 the price, get a Rythmik F12G with the GR Research driver. It is very close in sound quality to the Rel S line and also has speaker level inputs.

As some have mentioned and I can attest to, SVS is not a very musical subwoofer, but it has lots of "boom boom". I sold my SVS SB1000, sounded terrible with my Monitor Audio speakers. They actually sound better, stand alone without a subwoofer for now. I do have two SVS PB1000’s in my HT setup, and truthfully, great "boom boom" from movies. Enjoy your new Rel B3 and let us know how it works out for you, cheers.

I use an SVS 2000 Pro sub with my JBL L100 Classic speakers and I have gotten them to blend really well together.  They are a very musical subwoofer if you connect it correctly and use the SVS software to control the sub.  I spent close to a month dialing it in, made many notes, trial and error and got the sound “just right” for my taste. You are blaming the sub when you made the mistake to not check out fully what your receiver has for inputs and outputs.  Don’t diss the sub for your own mistakes.
