Mattnshilp, I have tried a very full range of room treatments and only found one that works very well and as a plus also is relative unobtrusive. I need to premise this by saying that both of my rooms are largely symmetrical. One is a 18' wide, 25' long, and 11.5' high and the other is tiny 10' wide, 13' long, and 8' high.
In the large room I have electronic isolation, LEDE, Tubetraps, Roomlens, RPG diffusers, acoustic mirrors, Harmonic wall dots, Syn. ARTS, etc. Most improved some problems, but most also had liabilities. Then I read a post by someone here on Audiogon about Zilplexes from the Netherlands. I got a set and initially was disappointed but learned that the one of eleven pieces that went on the ceiling was crucial but I had been unable to reach given the high ceilings there.
When I later used all eleven properly in my small room including the one on the ceiling, I was dumfounded as the room boundaries vanished! I returned them to the large room and managed to reach high enough to install the ceiling unit. Again I was struck by their benefit.
It is hard to understand how eleven 1/2" silver hemispheres sitting on three points on acrylic wall mounts can do what they do, but do they work! I think now that you have to order them directly.
