Alps - Diffuser Solid Wood PRD Diffuser Features - Omnidirectional Primitive Root and Geometric Diffuser - Optimized Primitive Root Reflection phase grating. - 49 phase Block heights Scattering range: 400 Hz to 8000 Hz Purpose - Improving low-frequency response - Flutter echo control - Specular reflection control - Enlarging sweet spot Alps is a hybrid primitive root / geometric diffuser, made from premium solid wood. Its characteristic two-dimensional optimized primitive root tunes the start of its diffusion range to lower frequencies. At the upper limit of the PRD’s effectiveness, the angled blocks provide geometric diffusion, originating broadband scattering and diffusion responses. Alps solid construction allows the panel to properly diffuser over its full range without losing energy to internal structural resonances. With an easy installation procedure, Alps W Diffuser is available in a wide variety of finishes, including lacquered surfaces. Performance Perfect reflection control on an elegant and fully optimized panel.
