Sonora® LFC
Low-Frequency Control Panel

|
 
Application
The Sonora® Low-Frequency Control (LFC) panel is unique in the Acoustics First line of sound absorbing products. These low-frequency absorbers are tuned for alleviating bass build-up in a room while allowing the higher frequencies to breathe. Broadband bass traps can be overused in performance environments where there are other products already in place to control high frequencies - like diffusers or other broadband threatments.

The Sonora® LFC is focused squarely on the rumble/boomy bass frequencies below 250 Hz. Sounds within these ranges are more susceptible to buildup from room modes and contribute to the "rumble and boominess" of a space. The Sonora® LFC panel is a great option for studios, theaters, or any critical listening environment where low frequency control is desired without over-absorbing high frequencies.

Construction
The core construction is a multi-density glass fiberboard with a resonant reflective face. It is then wrapped in an acoustically transparent fabric. Finishes are returned to the back for a fully tailored edge.

Edge Detail
All edges are resin hardened and square.

Standard Mounting
2 piece Z-Bars.
