I have two weeks before my contactor finishes all my sheetrock. If I but some of these low-prices speaker pairs referenced in other postings, how do I use them as individual speakers that output both channels? What is the exact unit to buy to set up a few zones and take advanage of the above just to get some background sound in each room? Do I still use my main Onkyo system or should I get a specific receiver to send sound to zones? Thanks BTW - why not just but some 6 x 9 car speakers with nice grills for the ceiling? They sound great in a car. Jack
