Waveform ® Spline G3
PRODUCT OVERVIEW The Waveform ® Spline G3 Panel represents the continuing evolution in architectural acoustics toward quantifiable, organic shapes. Developed using RPG's powerful shape optimization and aperiodic modulation technology, they are designed to blend the direct and reflected sound to increase intelligibility and enhance musical clarity and intimacy in performance spaces such as auditoriums, band rooms and choral rooms. One of the most powerful one-dimensional sound diffusers available today, the asymmetric Waveform ® Spline G3 Panel is constructed of non-combustible glass fiber reinforced gypsum (GFRG). They can be arrayed to reduce periodicity effects and be installed on walls or ceilings. SIZING • Standard Panel: 47-3/4" W x 47-3/4" L x 9-3/4" D • Material Thickness: 1/8" nominal (Other thicknesses may be available) • Each panel weighs approx. 3.00 lbs/ft 2

The Waveform ® Spline G3 Panel comes in a natural/ raw GFRG finish to be required to be painted on-site or factory color-matched to any paint color specification. INSTALLATION Overhead mounting of the Waveform ® Spline G3 Panel is achieved by suspending units from integrated hairpin loops using RPG-supplied engineered cables and hardware. Each panel can be hung as a “cloud” or screwed together to create a canopy. Units can also be mounted directly onto walls using RPG-provided integrated cleats.
