RPG Hemiffusor W1

The scientifically designed and tested HemiffusorTM that has become so popular for home theater, media and listening rooms is now available in an affordable, light weight, solid wood model. Each Hemiffusor W1 is hand crafted from Paulownia wood, which has earned itself the nickname ‘The Environmental Tree’ – see www.tropaul.com for more information on its many ecological benefits. Suitable for surface mount wall and ceiling applications, as well as lay-in standard 15/16” T-bar ceiling grid.

Specular reflections from flat, hard surfaces cause strong reflections that corrupt speech intelligibility and degrade music quality. Typically, fabric wrapped absorptive panels are used to control interfering reflections, with the undesirable side effect of deadening the space.

The Hemiffusor is the first and most affordable 2D QRD.It offers twice the reflection attenuation of the 1D QRD, because it uniformly scatters sound into a hemisphere. The Hemiffusor provides uniform, omnidirectional, broad bandwidth diffusion in an attractive ceiling or wall design element.


  • Finishes: Paulownia Wood (blonde color) with clear lacquer coating
  • Size: 23-5/8”T x 23-5/8”W x 4”D (Sits flush with T-bar for lay-in ceiling installations.)
  • MSRP: $399/unit, $749/box of 2
