KINETICS® HighTonesWood Diffusers

HighTones Diffusers combine the beauty of natural wood with the science of quadratic theory to create sound diffusing wall finishes that produce a superior acoustic environment.

Acoustical reflection is often desirable in critical listening environments to help prevent the deadening of sound energy. Higher frequency sound is easily absorbed by common materials such as curtains, fabric covered chairs, and people’s clothing.

Higher frequency sound reinforcement through early reflections off of the walls adds brilliance to music and improves speech intelligibility. Designing the room to create a scattering of high frequency sound reflections across the listening space is preferable and often required to prevent unwanted flutter echo.

HighTones Wood Diffusers are manufactured from 4" wide hardwood planks that are grooved in a sequence of sound scattering wells of varying depths. The planks are installed side by side so the sequence of wells repeats itself across a wide area.

  • Available hardwoods: cherry, maple, oak and poplar
  • Available finishes: unfinished, clear coated, stained and clear coated, and painted (poplar only)
  • Dimensions: 4" wide x 1" deep x 12" to 96" long
  • Slotted-back option available to add sound absorption
