DIY acoustic panels?

Look up ATS Acoustics, Piper City Illinois. I built several panels using their products. Have a good website.  

As a follow-up to my last post. I purchased from ATS: 1 box Rouxul Rockwood 60 panels 2", and Burlap fabric. I purchased 1 x 3" pine boards and hardware to make frames. I built 6 panels for the price of 2 pre made by ATS ($114). 

My listening room has to serve multiple purposes. And my wife is not going to let me put anything ugly or even technical looking on the walls (not that I want to either).

Ceilings are 10’ so I’m not messing with them. Left wall is 1/2" thick wood paneling but is mostly take up by two windows with heavy drapes. Back wall, behind listening position is all window, but again, behind heavy drapes. Wall behind system will soon be all books. The right wall is the issue. Solid brick. There are two areas, 4’x8’ that probably need attention. My plan is to hang oriental rugs over the brick in those places. Wife is okay with that idea and she will source the rugs. She knows where to get nice looking, older, but not high end rugs for the purpose. Still probably several hundred a piece.

DO NOT use live sheep as, although effective, they're messy and hate being stuck to a wall.

There are alternatives to everything, including big insightly refrigerator size panels and low WAF tube traps. You got your tiny little bowl acoustic resonators. You got your Mpingo discs. You got your crystals. You got your Corner Tunes from Michael Green. You got your Golden Sound Acoustic Discs for room corners. All you need is the XLO Test CD so you can determine precisely where to place the stuff since, you know, instructions are oft times too general to get you on right on the money.
