Pyramid™ Diffuser AVL Systems Pyramid Diffusers are lightweight acoustical control devices for mounting in standard grid ceilings or on flat surfaces. These attractive multi-faceted products are designed to achieve optimal performance from their shapes designed from with the use of computer modeling analysis combined with laboratory and application testing. All AVL Systems Pyramid Diffusers are manufactured to provide specular diffusion of the back-scattered sound energy without high-Q reflections and resonance. AVL Systems Pyramid Diffusors are constructed of multi-density, thermo-molded resins to dampen resonances and resist impact and damage. AVL Systems' diffusers are ecologically friendly; containing up to 85% recycled materials. Products are supplied to finish sizes as specified and ready to install with attachment devices for mounting to existing substrates or in standard grid ceiling systems. Lightweight - For Ceilings Durable, Impact Resistant White Textured Finish, Colors Optional Class A Fire Rating Excellent Acoustical Performance Low Cost   Interactive Performance The AcousTech™ and DiSorb™ families of interactive performance products are designed to provide the acoustical engineer and specifier with a complete toolbox of technically compatible performance products for any application. These engineered products can be used together as an interactive system, working together to optimally enhance the acoustics of any architectural space. AVL Systems offers a full range of acoustic products for virtually every application and technical requirement. Fire Performance Composite assemblies with standard finish will have a flame-spread rating of less than 25 (Class A) per ASTM E-84. Finishes White textured finish standard. Options include a wide selection of AVL Systems' standard fabrics or, Designers selection and C.O.M. Applications Pyramid Diffusers are well suited for rooms and spaces where proper sound and control is important. The design of these products allows the specifier to provide specular diffusion to scatter and blend the original sounds. This combination helps to improve speech intelligibility, as well as clarity and tonal separation for music and performances without significantly reducing reverberation times. The result is clear, spacious, natural sound to be appreciated by the performers and enjoyed by the room's listeners.
