I have 44 Auralex 2' x 2' x 1" SonoFiber absorption panels for sale. A box of 24 cost $400 retail. I built a theater for this couple and had some absorption panels left over. So I will Sell 24 for $200, all 44 for $350 and I will throw in the fabric to wrap them. If you live in the area and want myself to build panels let me know then we can work something out. I would also consider any trades you might have. I will sell them individually for $10. If you have any questions please email me at 321-302-4181.
