Matt C and ldgibson76 -
The shelving was designed by Rives Audio -- a 17 degree angle I believe -- to work as a diffractor and for storage.
My carpenter Jim built it for me.
Very smart to design your furniture for audio.
The final finish looks great. Even my wife likes it.
PS - Next time I need new carpet (eg after multiple 1yo vomits on carpet, etc), I'll talk to Wayne (funlvr1965). He has some great pics.
