These have been working very well for me The sound is great, the can get loud if you push them a bit... As far as i can tell the sound is full and detailed... I have the 5" set at the studio and like those as well...

Not an audiophile so grain of salt. These speakers seem decent and work for my purposes (youtube and gaming audio). So far no complaints aside from the lack of a detachable power cord for ease in routing. The energy saver thing was a pain till i found out there is a switch on the back to turn it off.
