I have four of the MKVI. Wanna buy? Like stated already, they are good for the $$$. Only if conditions are favorable. They need room as 87% of sound hitting you is reflected. Not for the bookshelf. Hanging them from the ceiling reduces the bass response. The highs seem distored and the lows were out of control at high volumes. I listen to Lamb Of God, Godsmack, Metallica, etc, mostly and like to get it loud without it sounding like something is being stressed beyond...I just got some Klipsch R7s. Seem much better so far...Like I said the Bose can sound wonderful for certain applications, but not for mine. BTW...mine are in excellent shape. Two are just broken in and the other two with only 1 hour use.
