Clearsonic SORBER baffles don’t just redirect sound – they absorb it! SORBER’s NRC ratings are greater than 90 % and outperform our competitors’ 2″ thick products! SORBER baffles are manufactured out of rigid 1.5″ thick compressed fiberglass encased in heavy-duty ‘trunk cloth’. All SORBER baffles are Velcro-receptive so thay can easily be attached to almost any surface.
Clearsonic SORBER are made by inserting a 1.5″ thick rigid fiberglass section into a heavy duty carpet cloth jacket and seal them shut using Velcro. SORBER baffles use fiberglass fill instead of less expensive materials because of it’s fire resistance and superior acoustic properties. All SORBER products have a Class A fire rating. SORBER products have a Flame Spread index of 0 and a Smoke Developed index of 65. Testing was performed by Omega Point Lab using the ASTM E84 Test Standard.

S1, S2, & S3 Baffles
SORBER S1, S2, and S3 baffles can be attached to the inside of the ClearSonic Panel to reduce the amount of reflected sound, or attached to a wall to improve acoustics in a room. The S1, S2, and S3 are velcro-receptive and easily attached to almost any flat surface. The 22″ width allows the panels to fit the ClearSonic A3, A4, and A5 panel systems.S3 Baffles can be used in IsoPacs in place of S2s for greater absorption.
S4-2 & S5-2 Baffles
S4-2 & S5-2 SORBERs are free-standing absorption baffles that can be used for a variety of purposes. Each S4-2 and S5-2 consists of 2 panels connected with a cloth hinge. S4-2s are 44″ tall and S5-2s are 66″. S4-2s and S5-2s are used in the rear of most IsoPacs, but can also be portable isolation for vocalists, horn players, guitarists, etc. Adjacent S4-2 and S5-2 baffles can be attached to each other using the sewn-in Velcro flap.
SORBER Height Extender
SX12-2 SORBER height extenders consist of two 1-foot high by 2-foot wide panels hinged together (overall width of 4-feet). They are designed to extend our S5-2 baffles to the same overall height as the A5 panel with an AX12 height extender.
Available in light or dark charcoal gray, this is the perfect addition to an IsoPac-A, B, E or F when even more sound control is desired.
Clearsonic SORBER Lid Systems
The STC and STS SORBER baffles are most commonly used as lid sections. The STC4 and STS4 are 2′ wide x 4′ long. The STC5 and STS5 are 2′ wide x 5.5′ long. STC412 and STC512 are 1′ wide each. STC sections are rectangular, while STS sections are trapezoid shaped.
