Hi, I have a precision acoustics hds10 and was thinking of getting another of the same model since I can get it for a good deal. Should I get 2 of these subs or just 1 more expensive sub? The hds10 sub is 150w rms and peak I believe, and goes down to 35hz. Would 1 10" sub say at 200w and something like 400w peak and goes down to say 25 hz be better? I am really happy with my current sub and goes deep and clean. But say I am playing a song with a lot of bass in it. It's clean. But when I turn the volume up, eventually the treble.midrange will soon be more louder than the bass from the sub. The sub is already on maximum and it's been calibrated with the receiver, so the sub has a setting like -15db or something so I guess u can't really tell where the bass is coming from even though I have the sub behind in the back center a rectangular shaped room.
