JBL MTC-81BB8 Pre-Install In-Ceiling Backcan for JBL 8138 Ceiling Speaker (MTC-81BB8)

The JBL MTC-81BB8 is a professional pre-install in-ceiling backcan designed specifically for use with the JBL 8138 ceiling speaker. Engineered to provide a secure enclosure and optimized acoustic environment, the MTC-81BB8 enhances speaker performance while supporting professional installation requirements in commercial and institutional audio systems.

Constructed from durable steel, the backcan provides a rugged enclosure that protects speaker components and helps isolate rear sound radiation within the ceiling cavity. This enclosed design contributes to more consistent audio performance while reducing sound transfer between adjacent spaces, making it ideal for commercial installations where controlled acoustic performance is important.

The MTC-81BB8 features an internal volume of 7.4 liters, carefully designed to complement the acoustic characteristics of the JBL 8138 ceiling speaker. The optimized enclosure volume helps support balanced frequency response and reliable speaker performance in distributed audio applications.

Designed for pre-installation during construction or renovation projects, the backcan allows contractors and installers to prepare ceiling infrastructure before the speaker is installed. This simplifies project planning, improves installation efficiency, and ensures a professional finished appearance once the loudspeaker is mounted.

The steel enclosure also provides additional structural support and protection, helping meet commercial installation standards while contributing to long-term system reliability. Its purpose-built design ensures seamless compatibility with the JBL 8138 ceiling speaker and related installation accessories.

Supplied as a pack of four backcans, the MTC-81BB8 is ideal for multi-speaker commercial projects and large distributed audio installations. JBL’s professional installation accessories are engineered to deliver dependable performance and straightforward integration with JBL commercial loudspeaker systems.

Ideal for offices, schools, hotels, hospitals, retail stores, conference centers, houses of worship, hospitality venues, airports, government facilities, and commercial AV installations, the JBL MTC-81BB8 provides a reliable enclosure solution for professional ceiling speaker systems.
