I have a Yamaha RX-V1000 main reciever which I believe has an out for a rear center channel. If I remember correctly there is no power running to this terminal so I would need a external amplifier to power this speaker. In which case I would like to hook my Yamaha RX-V595 to the RX-V1000 to power this speaker. I was just wondering how many of you have a rear center in your current system? Does it make a big difference, would it be worth the added cost to add this to my system. I currently have a Energy center, XL16's for the rears, DCM dual 12's powered by a 130w amp and rebuilt front towers with a new crossover and all new drivers.
