The Razorblade is a high-performance quadratic residue diffuser that employs an array of 15 wells - specifically measured to break up and scatter acoustic energy to create a diffuse sound field.
  • True quadratic residue diffuser
  • Full 8" deep with 15 wells
  • Diffuses energy from 400Hz up
  • Adds air and retains natural ambiance


Product Details:
Large, heavy quadratic residue diffusers like the Razorblade are commonly considered to be the most effective form of sound diffusion as they are able to control and disperse directional sound energy all the way down to 400Hz, thus eliminating problems such as standing waves, flutter echo and primary reflections while retaining the natural 'air' and ambiance of the room.

Razorblades are generally positioned at the 'receive' end of the room whereby sound entering the various wells is reflected back into the room at different times due to the various well depths. This effectively breaks up sound waves and their phase relationships, scattering the acoustic energy across a wider spectrum, eliminating resonant peaks.

The Razorblade is ideally suited for studio installations, soft seat theatres, high-end home theatres and performance venues.

Technical Data and Specifications:
The Razorblade is a true quadratic diffuser that features 15 mathematically calculated wells of various depths. As sound enters the varying wells, it is reflected back into the room at different times, effectively diffusing the sound energy. The walls and wells work together to refract both the on-axis and the incidental sound waves, scattering the energy into a true diffuse field. The result is peaks and valleys caused by the room geometry are smoothed out, resulting in a more balanced and acoustically neutral listening environment.

In effort control the widest possible bandwidth, this unique 'phase trap' has been developed to address directional frequencies above the critical 400Hz cutoff point and the all important voice range. Deep 8" wells are created from medium density fiberboard and plywood in effort to increase mass. These feature dado and glue construction to maximize rigidity. Each laminate is painted black while the outer shell is coated in a tough yet attractive black melamine finish for easy cleaning.

Measuring 24" wide by 48" high by 8" deep, the Razorblade is generally positioned in a lateral array at the receive end of the room. Though ideally suited for control rooms and studios where critical performance is required, the Razorblade can be used in all acoustic environments including soft-seat theatres, auditoriums, churches and home theaters - in fact any room that requires control of room ambiance.

Material Specifications:
  • Finish: Black melamine laminate
  • Internal Construction: Combination plywood and MDF
  • Dimensions 24" (610mm) x 48" (1219mm) x 8" (203mm)
  • Weight: 80 lbs.
