Q-Code

Picked up a pair of Capitol Heresy III’s for my 2-channel system, and with a Klipsch sub, I’m very happy with the sound matching nicely with my vintage Fisher 800-C. Now, I’m kicking around a crazy idea is to update the home theater system by replacing my Atlantic 350 THX 5.1 speakers with 5 Heresy III and a sub…..or, Cornwall III for L & R, Heresy III as a center, two 's Heresy's in the back for the surrounds and a sub. Room size for the theater is 20 x 19 with digital projection (and 16mm in the booth )----La-Scala’s are out of the question (to the wife they are, sigh…) so has anyone tried either of these matches for a 5.1 set up?
