Active Speaker Advice Sought for HT set up

[communiqueter]

Hi,

Just found your site; am no longer completely ingnorant, just mostly but am moving in right direction.

If site intended for 2 channel audio, oops, my bad.

We moved into a new home about two years ago, I now have a dedicated HT room. Current set up is Dynaudio 82's for fronts, 42's for rears and 122cc.

 

Pretty good, but for my two channel system I have been listening to a pair of ATC SCM10-2a's - to my ears, there's no comparison so now I want to go with ATC HT set up.

 

Room is 23' long by 10'6" wide with 7'6" ceiling. I recently just missed out on getting an ATC SCM C5CA centre channel which matches up with the ATC Active 20's which might be a good thing. Given my room size, if I had the C5CA, could I mate it with four active 10's or would they be overpowered?

Alternatively, would it make sense to use six active 10's - using one for cc and one for rear centre?

thanks,

Reid.
