Waveform ® Spline A
PRODUCT OVERVIEW The Waveform ® Spline A Panel represents the evolution in architectural acoustics toward quantifiable, organic shapes. Developed using RPG’s powerful shape optimization software, the panels have an attractive multi-curved appearance and are designed to bring early diffuse reflections to the audience, increasing intelligibility and enhancing musical clarity and intimacy. This aluminum-skinned honeycomb panel is one of the most powerful one-dimensional sound diffusers available today. The asymmetric Waveform ® Spline A Panel can be arrayed to reduce periodicity effects and be installed on walls or ceilings. SIZING • Standard Panel: 4' W x 8' L x 12-3/4" D • Material Thickness: 3/4" nominal • Each panel weighs approx. 2.00 lb/ft 2 Should the project require a higher unit mass, 1 and 2 lbs/sf MLV (mass loaded vinyl) backings are standard options.

The Waveform ® Spline A Panel is available standard in a white powder-coated finish. Units can be painted in custom colors or veneered with natural wood veneers, no laminates. INSTALLATION Overhead mounting of the Waveform ® Spline A Panel is achieved by suspending units from embedded eye- bolts using RPG-supplied engineered cables and hardware. Each panel is designed to hang freely as a separate “cloud” or tied together with brackets along the long or short edge to create a canopy.
