I've got the weekend pretty much set aside for the room (didn't have time last weekend). 8 more Cardas RCAs are arriving Friday which will round out the final four interconnects. Next project will be speaker cables although there aren't many choices available other than Jon Risch and Chris VenHaus.
Regarding the TV shelf I looked at a few options including building a removable diffuser such as:
However such an endeavor would seem impractical due to it's excessive weight. This led me to thinking about alternate materials other than solid wood. One material being foam blocks, the kind you'd find at a hobby store or even Walmart. Also those green Styrofoam 'planter blocks'. Only problem for these would be the cost, comparable number of blocks of the foam would equal about ten times the cost of regular 8 foot, 2x2 pieces of wood.
I could very well end up using wood, perhaps mounting the acoustic board on elevated legs and wheels with the ability to roll it out of the way and against a wall when I want to watch TV. We'll see.
Follow Ups:
The planter blocks are expensive because they are an open cell foam. That makes it an absorber at high frequencies and will attenuate the reflection off of it somewhat. It is only a good material because of the higher density . But styrofoam and PE foam are available at higher densities, at much higher cost, which might reduce their ringing with the characteristic "plasticky" noise that sounds like rustling. But your best bet with styrofoam skyline diffusors is to paint them with a hard setting latex paint.
or swim noodles cut to size :) but it is just not something you want catching fire in your house...
