Double Duty Diffuser™ Barrel Shaped Diffuser

|
 
The polycylindrical (barrel shaped) diffuser will act to scatter high frequency sound and trap bass in any location. Bass absorption will vary with size. A 2’ x 4’ unit has maximum absorption at approximately 125 Hz.  Increasing size to 4’ x 8’ lowers center frequency of maximum absorption to 63 Hz. Mid to high frequency absorption is typically 0.10 to 0.25.

The Double Duty Diffuser™ is available in white thermoplastic, standard Guilford of Maine FR701 Style 2100 fabric or other factory approved finish. Units have the option to be lined with a 1-1/2” thick layer of glass fiber batting to increase absorption and prevent resonance. Lining is standard in larger sizes.

Diffusers are wall mounted using provided “L” brackets.  Configurations are available to fit a standard T-bar suspended ceiling grid.
