Does a Powered Sub need a Preamp?

Have you made much effort on your room? Money should go on acoustic treatments before equipment upgrades, I feel.

Thanks a million, Really, I tried and the stats just arent to be had. I was planning on going that route myself as it seemed easiest that way.

the computer works perfect with the quads but their input sensitivty is something like 0.075 Volts I think, He has the manual now and I cant find one on google.

My best friends system until now consisted of a pair of the smallest computer speakers I have ever seen, with a 4" subwoofer I could throw across a room with my index finger (Just a little to much weight for the pinky). He listens to rap and a subwoofer is absolutely necessary for electronic based music, at least what we listen to. Although I had my 18" sub in the middle of the room and finally moved the whole system to get it in the corner and my bass is 3x better at least. I thoroughly agree with room acoustics.

Thanks yall.

Ah, I just noticed I replied to completely the wrong thread! I think Almbarg had you covered :)
