Intended for demanding hifi listeners, it improves the overall acoustics of the listening space.\u003cstrong\u003e Instead of absorbing the sound waves, as usual isolation does, they are evenly diffused.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe main advantage rests in \u003cstrong\u003efilling the listening space with sound without unwanted linear reflections\u003c\/strong\u003e from flat surfaces.

Milk glass evenly disperses, or \u003cstrong\u003ediffuses\u003c\/strong\u003e the light beams. The exact same effect of \u003cstrong\u003eevenly and regularly dispersing sound\u003c\/strong\u003e is achievable with an acoustic diffuser.\u003c\/p\u003e\n\u003cp\u003eAcoustic Diffuser – Theory, History\u003c\/p\u003e\n\u003cp\u003eThe formula for the calculation of the diffuser shape is based on quadratic differences of sequences from the elementary number theory, as described by mathematicians A.

The 2D-QRD quadratic diffuser has excellent efficiency, \u003cstrong\u003eits behaviour can be calculated\u003c\/strong\u003e and it works in both horizontal and vertical planes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Hybrid Diffuser Version A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign:\u003c\/strong\u003e Circle pattern with greater absorption efficiency\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStandard Panel Size:\u003c\/strong\u003e 1m × 1m\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFront Absorptive Area:\u003c\/strong\u003e 1.161 m²\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFront Reflective Area:\u003c\/strong\u003e 1.42 m²\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHeight:\u003c\/strong\u003e 103 cm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWidth:\u003c\/strong\u003e 104 cm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDepth:\u003c\/strong\u003e 17 cm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 15 kg\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOther Sizes Available:\u003c\/strong\u003e 2m × 1m, 3m × 2m\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCustom Sizing:\u003c\/strong\u003e Available upon request\u003c\/p\u003e","brand":"RD Acoustic","offers":[{"title":"Default Title","offer_id":52185813352769,"sku":"RDA-QRD67-DIF","price":19000.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0993\/2636\/1921\/files\/RDacoustic_acoustic_Diffuser_QRD67_small_3433510a-d1dd-4676-a3f0-84b3cecff82f.jpg?v=1788914573","url":"https:\/\/www.magentaaudio.com.au\/products\/rd-acoustic-quadratic-diffuser-qrd67-1","provider":"Magenta Audio","version":"1.0","type":"link"}
