Put me on the list, as the proud owner of Klipsch Promedia GMX-A 2.1. I've fixed the lack of bass few days ago, at first I thought why do people say the bass is boomy becasue even at max volume, theres barely any bass,

I opened up the preamp and I found out one of the capacitor fell off, soldered it back and now I know what do you guys mean. I'm not a bass freak, I cant even handle bass at more than 1/4 of the knob turned
