JBL's MTC-81BB8 is designed for use in applications requiring preinstalled backcans and is compatible with ceiling speakers having a 286 mm (11.25") mounting circle diameter, such as the JBL 8138 ceiling loudspeaker, and the JBL MTC-81TB8 tile bridge for suspended ceilings. Providing a larger backcan air volume than most cost-effective backcans, the MTC-81BB8 allows ceiling speakers to produce extra bass capability for a wider frequency response and improved overall sound quality. This angled-wall backcan nests to reduce inventory space and transportation costs.

The MTC-81BB8 is supplied with five conduit knockouts, four clip-nuts for tile bridge to backcan attachment, as well as acoustic lining and two perforated bend-up mounting straps.
