Resonator Sound Absorbers

Resonator Sound Absorbers are highly effective, low frequency cylindrical ceiling absorbers used to quiet reverberant rooms. These attractive units are available in a wide variety of colors and fabrics. Resonator units are 12" in diameter, 24" long and weigh approximately 6 pounds.

Resonator units are made of specially engineered molded fiberglass. Aluminum trim rings cap both ends of the units adding to their durability and appearance. Internally, two metal resonators add significant low frequency absorption to these stylish units. They are easily installed from an overhead structure using light gauge wire.

Resonators provide the equivalent in overall sound absorption of 10 to 15 square feet of good acoustical ceiling tile.
