yes,s330's woofer will not have sound if u turn the bass to 0%,for best sound quality,turn to 60-70% is best for daily listen.depend on what kind of music u listen.actually the subwoofer will no sound when u turn it to 0% is becoz each channel is doing it job perfectly,meaning the sound is divided,satelites handle treble and midrange while subwoofer only produce low frequency sound.This is mainly due to the internal sound control chips of s330,it has 2 which is called 5532 and TDA7379,the two pieces 5532 control the front 2 channel, TDA7379 is a four-channel chip in  S330 , each of the two-channel constitute a BTL  structure, to form four groups of output, respectively, the two groups to push satelites and the other two groups were to push the dual voice coil woofer.Just my opinion

i have a altec lansing vs4121 which is also will produce bass even i turn the bass to 0%,it is quite annoying for its bass characteristic.

I'm about to buy S330 now, but is the bass so lousy?? I'll use it not only for music, but also for gaming le....And its not cheap. Hope i wont get the wrong one
