The M60's(or 80's) are definately the better speaker for a room that size.

If it's a cylinder sub you like, Hsu makes them as well. (SVS designs are based on Hsu's subs). You're room could certainly handle the TN-1220HO from Hsu. If you like the Rosewood look. The VTF-3R (down firing Rosewood version of the VTF-3) is actually on sale for $849. (There's a code you need to post at checkout to get the discount)
