I have for sale 8 acoustic panels. 6 were purchased from ATS Acoustics and are of the following dimensions. 2 bass panels in burgundy @ 24x48x4 and 4 panels in black @ 24x48x2. In addition, I have 2 GIK acoustics monster bass traps in brown @ 24x48x8. All these combined worked wonders in my audio setup, but have to go because I sold off my system. Pictures will be forthcoming. I will only sell as a package and will entertain offers for pickup only in Minneapolis. Test the final frontier on this musical journey, and save some money on shipping. Thanks
