I was going to get teh M&K K7 for my front stage (Left,center,right) and M&K K4 tripoles for the rear surrounds. I have heard this combination and have been blown away by the sound. I was goign to ceiling mount the K4 tripoles since my room shape is so weird. (Here is a link to an imagestation.com album which has my room shape and layout: room layout @ imagestation) I was going to hire someone to run cables from the TV corner to the backs of the room in the ceiling to avoid having cables exposed. After thinking about this, perhaps In-wall speakers for the rear surrounds would be better and cheaper? Or should I stick to the M&K K4 tripoles and mount them on the ceiling?
