I am remodeling my kitchen and want to install 2 in-ceiling speakers that I would like to hook up to Airport Express and use Airplay. Do I need to connect the speakers to an A/V reciever or does an in-celing speaker exist that can be pluged into the Airport Express and then directly into a power outlet (I have free-standing speakers in my bedroom hooked up this way). If the answer is no, does this mean I need another A/V receiver to power these speakers. I have a Denon AVR-1912 receiver in my living room, but all 7 channels are being used. Please Help. Thanks!
