Panels are constructed of rigid E-glass, molded into a one-piece offset, inverted pyramidal shape that provides high impact strength and hardness with light weight and ease of installation. The offset shape provides an infinite combination of mounting positions to maximize the fine-tuning of sound diffusion.• Standard finish is white textured gel-coat or fabric wrapped. Colored gel-coat is optional.

Standard panel sizes are: 23 3/4" x 23 3/4" x 8"h, 23 3/4" x 47 3/4" x 12 1/2"h, 47 3/4" x 47 3/4" x 12 1/2"h.

Options include: Internal Liner for reduced sound absorption and sound transmission. Internal absorber for increased sound absorption of low frequencies.
