Uh no. The bigger the room, the (way) more power and the larger the speaker/subwoofer you will need. You don't need a big room to have low frequencies. Actually, most big rooms I have auditioned systems in never sound like they have much bass cause the speakers can't load the room sufficiently. I have friends who have given up big rooms with big amps ($$) and big speakers ($$$) in favor of a little room that gets even more bass extenstion out of a small system. That is my 2 cents. Just didn't want you to only believe part of the answers. Reread my post above. If you want a large room and have a large budget and want subwoofers, then go for it, but you don't need all that for deep bass.
