I have asked this question before, and wanted more bass as well. After steve modded my gt my sound was crystal clear so a new speaker i doubt would help much. Steve mentioned getting some kind of small cup to put behind the speaker to create bass. The way i see it, is the trick is gonna be whoever finds just the right thing to put behind the speaker to get that bassy output. I had also thought about maybe two smaller speakers, psp types maybe, for stereo. Honestly though, i can only hear in mono so bass is more important to me.
