I listen to alot of trance, so my speakers are put through their paces alot
Though, this Creative Inspire set, even though it does have bass, with a subwoofer and everything, its not as powerful as a Logitech system would be.
Maximum low is around 44hz.
The MP3's okay, though it seems like theres some tempo troubles throughout
I can hear all the bass, and it rumbling and everything, but yeah, on my speakers, theres a bit of rumble that shouldn't be there (i.e vibration of the cone (thats slightly higher)).
