I use two Hsu VTF-3 MKII subs that nearly bring the house down and my theaters is in the basement (carpet over poured concrete). A single VTF-3 is 350w, 18Hz and can hit 16Hz. A single VTF3 pressurizes my 13x24 room really nice. I won't even say what happens when both are going. There really should be a law against running two of these in a room the size of mine.

What size is your room and what SPL do you intend to listen at? Also what kind of extension do you need?
