I seem to recall reading somewhere in the forum that some users have connected additional speakers directly into their AMP in order to provide the rear centre channel in a 6.1 set up. Is this correct? How have you found the performance to be? I was thinking of using a couple of these panels as my rears in a 5.1 set up. Is this feasible? Let me know if I am barking up the right tree or just plain barking mad!! Cheers
