My friend at work mentioned today that he would like to add in wall surround speakers to his HT. He currently is running with all PSBs, none in wall though. Im not sure what series of PSBs he currently owns, but I do know he wants to stay around $200-$300 on the in walls. Does anyone know if PSB makes a good in wall speaker, and if so which one? If anyone has any suggestions on any other in wall brand that would be timbre matched to his current PSBs that would be good too. Thanks
