In the process of putting together a surround sound system. I believe I will go with a Yamaha RX-2600 Receiver. I am lookign for help and recommendation on in-wall speakers. SPent quite a bit of time looking at Definitive Tech Speakers here is what I have come up with: SUB: IWsub 10/10 Front: UIW BP/A Ceiling UIW 64/a Center: either C/L/R 2000 or 2300. What do you think? Do I need a sperate amp to power the 10/10 as suggested by Def Tech? What configration of RBH speakers would you recommend to be similar to the Deft Tech System? ARe their any majir differences between the RBH and the Definitive Tech. What are you opionions between RBH or Definitive TEch? Thanks
