Maybe you missed my comment in an earlier post, but I don't think the lever fits in with Summa's focus on small rooms (see earlier comment).

Duke and I have talked about this at some length because we know that we need a subwoofer in the line. But I want to do the right thing not just the new thing (even if I do own the patent).

Not to give away too much, but we are looking to make a small low power subwoofer that is inexpensive to make so that the cusotmer can buy and use two or three of them around the room. The problem is that we need the system to cover about 25 - 50 Hz. which is incompatible with "small" and "inexpensive". When I get this problem worked out, I'll let you know.

But thanks for your interest. I am sure that someday we will see a high output lever used in Pro sound applications since this is the ideal application.
