Keep SVS SB16 or change to REL S5 music only

You know, I think Erik is probably right.  I imagine the SVS SB16 could be tight and musical if set up properly, which can be extremely difficult I imagine.  

Do you have someone who could maybe help with set-up?

I'm a little surprised that Audiotroy found the SB13 Ultra to sound slow and boomy. I'm using a pair to augment my Wilson W/P system, and they are extremely fast and tight. I can see how a 16" might not be as musical.

I have 4 PSB T3's plus a C3 center in a 5.1 system I use for both movies and 2 channel music. The REL S5 SHO helps to create a palpable sense of space that is full of subtlety and layers that substantially elevates my listening experience. 

Recommended. 

I have now changed out the Svs sb16 to the new Rel S812 and wow what a difference! The Rel sub is miles better to music, it dont make the same pressure on electronic music but all other music feels mutch more a live now and not sounds boomy. 

n_brio,

That's great that you like the RELs. I've owned SVS SB13 ans SB16, dual JL Audio F110s and a single F112 v2,  HSU, Martin Logan Depth i, and now dual REL Carbon limited subs. I agree with b_limo, "They just disappear, widen the soundstage and clean up the mids and highs noticeably." I actually prefer JL Audio for HT, but absolutely love my RELs for 2-channel.
