i just ordered these for work but i personally have a Bose Companion 5 set. which is the comparable setup (not in price or performance but the two satellites and a sub) and if this comes anywhere near what the Bose can do i will eat my sub. the Bose system minimum and maximum response levels are miles further in each direction. the subwoofer has feedback cancelling in it that completely eliminates screech over 20khz
the subwoofer is tubular like a bazooka tube but has a ~14lb driver magnet. it has enough power to make me turn the volume down for fear of shattering my windows with vibrations. it also creates a pseudo 5.1 surround envelope in the room it is in. in short these speakers are probably good to the uneducated ears but if you really care about your audio quality i urge you to look at more serious speakers.
