Asking $45. Just purchased. Never used. Manufacturer calls these "2nd quality" tiles. Any defects are extremely minor. At least 15 or more tiles look 1st quality. Others have a range of 1 to 25 pinholes in the back (see photo below), 2-3 have very slight partial discoloration. There are no tears, crust, deformities in any tiles. Performance is not effected by the quality of these tiles I'd say. I have enough absorption in my room which is why I'm selling these. (FYI: 3" Wedge Foam has a more linear NRC profile than 4" Wedge Foam. 4" Wedge has a large spike at 500 Hz.) Contact me for UPS shipping quote (will be around $16 depending where you live). I accept Paypal, money order.
