Gents....in response to your questions...
I'd prefer to put them in the EC if possible for looks. The cabinet sizes are 21" x 21" x 14" deep. I already have a problem getting the Abyss in, but was hoping the Dynamos would work out. Otherwise, cut out the back of the EC to make room for the Abyss or place it outside the EC.
The rest of my speakers are Klipsch. RF-63 towers, RC-64, and CDT 5800's driven by an Elite SC-07 receiver.
As for DIY, not looking to do it this go around.
I don't have a particular price point other than cheaper the better and decent quality. I'm not looking for my clothes or the house to shake, just wanting good sound!
Thanks
