Audiolabyrinth, yes I once invested in a live end/dead end room. After about two nights of hoping I had not wasted my effort and money, I tore it all out. The Tube traps had the same impact. Then are read about diffusion. From The Handbook of Acoustics I had profession model WPG diffusors built. They lasted about five years.
As I said, now I have eleven little 1/2 inch bowls on my walls and ceiling. I have no absortion at all other than me, a carpet, some furniture and thousands of records and cds.
