I'm finishing up my dedicated theater which will have a DIY AT screen. The speakers will be on the stage behind the screen. I've got a pair of RF-62 II's for the mains and RS-41's for surrounds. I need a center speaker and have the space for a tower. I've found an open box RF-42 for $175 shipped. Or should I bite the bullet and drop the $350 on a new RF-62 from my local dealer? Or should I save $100 and pick up an RC-52?
