stormbv I know what you mean. These lack just a tiny bit of mid or hi tones. I'm not sure which as I am not an audiophile, but I can detect it. I think it has to do with the use of a phase-plug driver vs a normal speaker's tweeter. Somebody will correct me if i'm wrong.
That said, they still sound excellent. Can't beat the bass for great musical depth, even when it is turned all the way down. And as already mentioned, at high volumes (extremely high volumes) there is no distortion.
Incidentally, i will repeat this again: with these speakers you can get a MUCH better sound by using Winamp + the Sound Solution DSP. Configure Sound Solution to the setting "BRIGHT AND DENSE". My only caveat is that Sound Solution takes a punch at the CPU cycles, so this is for reasonably fast systems only (mine is a 1.3GHz, and it slows down multi-tasking, but it is worth it).
