Thanks for the kind words and stopping by our showroom. We got away with doing less on the HVAC since our ducts were already pretty quiet before we put in the extensive ductwork to lower even more. I think that cost us $3-$4K or so.I knew it! When I popped in to check out the main home theater room, I kept thinking the HVAC ducts was holding the room back I'm kidding of course. Incredible sound and in my opinion, even more spectacular picture. It's the best projector system I've seen yet.
