Which Sub Woofer is good for my 2 channel system

I've tried subs with B&W speakers before, only ending up taking the sub back to the store. Turns out that for music, I prefered the balance afforded by the full range speaker, even if the bass was a wee bit shy. My vote is NO sub with your great 805 Sigs.

At 12' x 16' I wouldn't go to the point of running 2 subs! I own 2 Rel Starta II's that I run w/ B& W's in my 34' x 16' room & yes 2 subs do wonders for a room of this size. IMO the Rel is the better sub as far a music is concerned.

I just purchased a Martin Logan Depth for my 2-channel system recently. I chose the Depth after an exhausting search for the "right", musical subwoofer. I listened to subs from Velodyne, JM Lab, REL, Titan, VMPS, and Martin Logan's smaller Grotto. They were all very good, but I had to give the nod to the Depth.

The Depth is exceptionally fast, taut, clear, defined, controlled, and blends with my JM Lab monitors seamlessly. I really wanted to spend only around $1,200 for a sub, but I absolutely felt compelled to get the $1,700 Depth. I also heard the $2,700 Descent, and it was better, but not necessarily in terms of clarity; it just had more physical impact.

Good luck!

I just added a VAndersteen 2W to my 2 channel system. Fast and tight it is. You can buy a new 2WQ and get to adjust the Q, for about the $1200 you wnated to spend.

Just auditioned the Rel Strata lll That has moved to the top of my list. Thanks for that suggestion. I do want to audition the Depth, hope to do that this week also.
I appreciate all your comments.
