Learning about my room and my sound..

Larry (Cello), I had the level one service performed by Rives on my room and they were a pleasure to work with. I followed their final recommendations regarding treatments, locations of same, and equipment placement. The equipment placement was a 180 degree change from where it was before we started.

End result: Most effective cost/benefit upgrade I have ever done. Room aesthetic is pleasing, acoustic is wonderful, and my music has never sounded better, not only to my ears but to those ears of some fellow AudiogoNers whose knowledge and hearing I respect.

Rives is highly recommended. Richard Bird is very easy to get a hold of, listens to what you are telling him, and is VERY generous with advice.

Advent11,
Sorry for the delay in response. I have not been posting too much lately. Too many other things going on.
To answer your question. Every treatment, right down to the rug on the floor is there per the "Rives plan". The corner treatments are RPG Variscreens. They are very expensive, but very effective hinged screens that are reversible. One side is diffusion, one side is absorbtion.
The ceiling treatments are from Quest Acoustical Interiors, as are the wall treatments. The fabric covering them is from Guilford Of Maine, acoustically transparent and available in a host of colors. You order the panels from Quest in the color you want and they arrive ready to hang. Both RPG and Quest give Rives clients a discount. Depending on the amount and type of treatment Richard recommends a lot of it can be DIY. Richard will give you lots of great advice if you want to go that route as well.
Rives gave me basic dimensions and materials type for the floor rug and I took it from there. The room had an artificial fiber wall-to-wall with hardwood under it. The plan called for pulling it up and replacing it with a 100% wool area rug. I purchased a Persian carpet through a rug broker. I ordered everything directly from RPG and Quest and installed themself based on placement as laid out in the final room plans from Rives. All the window treatments and the doors were done based on their recommendations as well.
