Hi Bruce,

My System consists of:

603 - Front L & R
CC6 - Centre
DS6 - Rear L & R
DS6 - Centre Rear ES/EX Duties

I have no problems with the DS6 rears, i think they are very good speakers which sound excellent in this configuration.

I chose the DS6's as the rear centre because i think i prefer the more diffused sound instead of the direct sounding 601's. Unless i'm mistaken i think this is the recommended setup anyway.

There has been some critisism of the bass handling of these speakers, but believe me i've had no problems. The speakers have handled everything i've thrown at them.

Hope this helps !
