Generally very good volume, zero bass
I use these speakers as right and left fronts in a 5.1 setup and the sound that comes out is clear, crystalline, in the highs and mids. After a little break-in time (an hour or two) they are very clean (at the beginning, there is some sputtering in the loudest moments, but it eventually passes).
On the other hand, below the midrange, there is no sound: no sound below 60hz, and a big hole between 100Hz and 140Hz.
The rest of the response is perfectly acceptable in this price range. To be coupled with a good subwoofer and not to be used as a monitoring speaker.
