Hey Granny,
It is truly amazing what proper room treatment can do for your sonic enjoyment. TV between speakers is always a bad idea. It seems like a great idea for us, but speakers hate it. I guess a drop down screen would work they even have acoustically transparent ones.
If you experiment you'll find placement of your traps and diffusors can make a difference also like distance to the floor and ceiling and how to treat the reflection points. Diffuse or absorb? Right now I do a combo of the two. It would be cool if there was an aerosol spray product that when used and music was played you could actually the radiation patterns of the speakers, what happens when the waves hit the walls, and the effects room treatments play. Maybe there is a computer program tha would let you input room dimensions, speaker type, placement in the room, and treatment placement. This would be very cool
Have lots of fun though. Can't wait to see your pics.
For you would be buyers, GIK, has many cool products that can work magic in your rooms and not make your room look like a studio. I wish I'd discovered them before purchasing the variety of products I'm using such as Auralex and Ready Acoustics (I'd never but anything from the folks at Ready again.)
