{"product_id":"qrd-diffusers","title":"QRD Diffusers","description":"\u003cp\u003eMCA \u003cstrong\u003eQRD Diffusers\u003c\/strong\u003e are one-dimensional acoustic diffusers designed to scatter sound evenly across the horizontal plane. Built from Baltic Birch plywood using a quadratic residue sequence, they deliver even, natural diffusion from 992 Hz to 3,274 Hz and come in two designs. Standard separates every well with thin fins for the most even diffusion we build, in 2' x 2', 3' x 2', and 4' x 2' sizes. Stepped delivers similar performance with a more sculpted look, and it's our only QRD available in a 6' x 2' length. The most versatile diffuser in our lineup, they work beautifully on listening room side walls, in tracking rooms and control rooms, and in churches where clarity and connection matter.\u003c\/p\u003e","brand":"Music City Acoustics LLC","offers":[{"title":"Standard \/ 2' x 2'","offer_id":67906330034396,"sku":"QRD 2.0-2X2","price":280.0,"currency_code":"USD","in_stock":true},{"title":"Standard \/ 3' x 2'","offer_id":67906330067164,"sku":"QRD 2.0-3x2","price":324.0,"currency_code":"USD","in_stock":true},{"title":"Standard \/ 4' x 2'","offer_id":67906330099932,"sku":"QRD 2.0-4X2","price":342.0,"currency_code":"USD","in_stock":true},{"title":"Stepped \/ 2' x 2'","offer_id":47469366083804,"sku":"QRD-2X2","price":282.0,"currency_code":"USD","in_stock":true},{"title":"Stepped \/ 4' x 2'","offer_id":47469366116572,"sku":"QRD-4X2","price":328.0,"currency_code":"USD","in_stock":true},{"title":"Stepped \/ 6' x 2'","offer_id":52090816823516,"sku":"QRD-6x2","price":443.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/8430\/6140\/files\/Quadratic-Residue-Diffuser.jpg?v=1793039045","url":"https:\/\/musiccityacoustics.com\/products\/qrd-diffusers","provider":"Music City Acoustics","version":"1.0","type":"link"}
