We’re introducing a radical new approach to backboxes: the Muffler. This innovative backwave enclosure gives all the benefits of a traditional backbox, including a 9 dB drop in transmitted frequency in adjoining rooms (above 200 Hz). Plus, it’s plenum rated, and can be used in new construction and retrofit installations.
We developed an acoustically novel skinned foam.
The foam is soft enough to squish into a retrofit cutout, but dense enough to act like a 1″ thick MDF backbox, blocking sonic transmission into adjoining rooms.
Like MDF backboxes, the Muffler attenuates frequencies above 200 Hz a minimum of 9 dB.
Dimensions
Unfolded, the Muffler measures 12-1/2 x 10-1/2″ (318 x 267 mm), with a depth of 5-1/2″ (140mm) into the ceiling. But the beauty of the Muffler is its pliability. So if your ceiling depth is only 4″, the Muffler conforms to the given space, providing all the same benefits.
You’ll love how easy it is to install.
For new construction, install a pair of BR68 brackets to “claim the space.” Install the Muffler later, at the same you install the speakers.
For retrofit, simply push the Muffler into your cutout prior to installing the speaker. A folding bracket and drywall clips hold the Muffler snug to the ceiling, eliminating air gaps. The speaker installs as usual.
The Muffler will be available November 2011.
