ok im opening pandoras box here.(treatment vs framed wall art)

If you have a room specially dedicated to sound, what you've got is a very, very big set of headphones.  And some like that.  

For me a sound system should live with the rest of the family and the rest of the home.  I do what I can in terms of room placement and such and then live with it.  Results are all that really counts and most who come to visit my home leave with envy.

         I am using panels from gik. My problems are under control,again i started this thread because of seeing some of the sysmtems on the gon with walls covered in pics and wondered what they were or were not using to control the slap echo etc.

I sent a jpeg of a pic that a friend took to Acoustimac.  They made it into two 2x4' panels.  Very cool, and an original.
