QRD® 734F is a one-dimensional sound diffuser developed to expand the product line anchored originally by the classic QRD® 734 Panel. It is the first product of its kind offered on the market. With a patented folded well design, the QRD® 734F extends the diffusion bandwidth into the lower mid-range frequencies in only 4-1/4″ depth, whereas other diffuser designs require at least 8″. The natural wood construction of the unit limits the amount of sound energy removed by absorption while the diffusion performance extends over 4 octaves.
