Thanks for all the excellent and thought out answers you guys. I really appreciate it.

I think I have to agree that probably the best solution is to get a sub. That way I shouldn't have to crank up the volume too much, and potentially damage something. I did get to try an 8" down-firing sub from Elac (german brand), but it sounds a bit sloppy.

Can anyone suggest a nice clean sub to try, for the dimensions of my living room?

thanks!
