Even though acousticians have long identified the benefits of treating the tri-corner, the difficulty of mounting acoustic panels in corners and a lack of ideal mounting options have discouraged people from taking advantage of this prime room location.
The Primacoustic Cumulus presents a simple and elegant solution. It is a surprisingly basic acoustic device combined with ingenious mounting hardware. Once installed, the Cumulus looks terrific and is highly effective at reducing low-mid frequencies that are attributed to ‘boomyness’ in a room. The magic lies in both the quality of the acoustic panel, its innovative design and the corner mounting location.
The 24″ triangular Cumulus panel is made from high density 6lb per cubic foot rigid fiberglass (A). The same material broadcasters and world-class studios have used for years to control room acoustics. The panel is fully encapsulated with micromesh (B) and employs resin hardened edges (D). These panel treatments combine to ensure the minute glass fibers cannot escape and produce pleasing architecturally straight lines. The 2″ thick panel is then covered in an acoustically transparent fabric (C). The edges of the Cumulus trap are reversed beveled and form a wedge shape (E) that flush-mounts and naturally transitions from the walls and ceilings to create an elegant corner trap.
The strategic corner placement combined with the high performance acoustic panel and cleverly created air cavity behind make the Cumulus a highly effective broadband absorber. The Cumulus is available in three neutral colors that will easily integrate with the most architecturally demanding room designs.
Each side is 24″ in length and, when in place, creates a 17″ deep air space cavity behind the panel that increases the bass absorption characteristics. Mounting Cumulus traps in a room will generally yield a significant reduction in the problematic low-mid region while leaving the architectural design of the room virtually intact. Invisible mounting is achieved using spring-tensioned clasps and a single eye-screw. Mounting literally takes minutes and because of the reverse beveled edges Cumulus traps flush mount ‘seamlessly’ into the room esthetics.
Cumulus traps have been tested to meet stringent class-1 fire ratings making them suitable for use in residential and commercial spaces.
