When I heard from the customer that the room the system would be installed in would be round, it made my head spin.
I've been in dome buildings and round buildings, and they've always echoed horribly. I still remember being in the dome house of a friend in the Philippines and sitting at the dining table, you could hear everything going on in the bathroom. There was absolutely no privacy because every whisper can be heard anywhere in the house. The house wasn't designed for privacy - the dome shape was supposed to withstand the worst typhoons in Cebu..... it didn't.
The customer had a previous system in the room, and he said that it did sound good, and he had designed the room correctly using principles of physics and math. That was one reason why I had to go - to satisfy my own curiosity, and to make sure that it wouldn't be a negative demo of the "Genesis sound". It worked better than I could have ever imagined.
It was absorptive, but the room was still quite "live" - not at all dead. The material was something that I was not familiar with. The surface looks like those trays you buy eggs in. It's a sponge, but the tips were much softer than the valleys. Like a variable density foam. They were in huge sheets.
