I am asking $30.00 each for four 2ft x 4 ft absorptive panels by ATS acoustics. Construction is wooden frame with 2 in of Roxul AFB rock wool absorptive material. Covering is a red microsuede fabric.
These can be wall of ceiling mounted with the clips supplied by ATS, but I simply hung them on the wall using picture wire and hooks (weight of each panel is approximately 12 lbs). The manufacturers original mounting hardware will be included.
ATS gives the following absorptive values for these panels:
1/3 Octave Band Center Frequencies, Hz
125 250 500 1000 2000 4000 NRC
0.18 0.91 1.02 0.72 0.49 0.43 0.80
More information can be found on the manufacturer's website: http://www.atsacoustics.com/panels.
thanks for looking
