Summary: Very crisp clean trebel. Bass is tight and for my ears I need to boost the 30-60Hz range by 3 dB (this is with the subwoffer in the detent midrange position) I use almost no Bass boost on the low end and no high end boost for normal casual listening. For Rock, low and high boost might be considered normal. Classical could be flat but the small bass boost is OK. Great speakers for the $. I am using with a Sound Blaster Audiology card. I am happy with my purchase.
