Our PFP-.50 unit is 57″ tall, 27″ wide, and 2.5″ deep and weighs 30 pounds. Different sizes available. Levels of absorption begin at 125 Hz. and go through 6,500 Hz. Our foam rates are smooth and do not have any drop outs or dips in the frequency response. Notice the impedance tube test results. Our PFP-1 and PFP -2 are thicker foams that start at 100 Hz. and go through 6,500 Hz. with a higher rate of absorption due to their greater thickness. Contact us for proper thickness to use for your particular application.
