JBL MTC-81BB8 Deep Backcan For 8138 Ceiling Speaker, 4 Pack - Priced Each

Designed for use in applications requiring preinstalled backcans, the JBL MTC-81BB8 is compatible with ceiling speakers having a 286mm (11.25") mounting circle diameter, such as the JBL 8138 ceiling loudspeaker (sold separately), as well as the JBL MTC-81TB8 tile bridge (sold separately) for suspended ceilings. Thanks to a larger backcan air volume than most cost-effective backcans, this unit enables ceiling speakers to produce extra bass capability for a broader frequency response and overall enhanced sound quality. This particular product consists of a 4-pack of backcans, priced each.

It comes supplied with 5 conduit knockouts, 4 clip-nuts for tile bridge to backcan attachment, as well as acoustic lining and two perforated bend-up mounting straps.
