Jbl Professional MTC-300BB8 Back Can Enclosure 1 Cu Ft

Product Description

The JBL PROFESSIONAL MTC-300BB8 is a 1 cubic foot back can enclosure designed for use with compatible ceiling speaker installations. Back cans serve as the acoustic rear enclosure for in-ceiling speakers, controlling rear-wave dispersion, reducing bleed into adjacent spaces, and improving overall low-frequency response. This unit ships as a single enclosure and is installed by audio-visual integrators, commercial sound contractors, and licensed electricians working on distributed audio systems in commercial or institutional settings.

This back can is suited for commercial and light commercial ceiling speaker deployments where an enclosed rear cavity is required by specification or code. Typical applications include conference rooms, corridors, retail spaces, and multi-tenant buildings where sound isolation between ceiling cavities is a priority. It is intended for use with compatible JBL PROFESSIONAL ceiling speaker models that require or accept a rear back can accessory.

Key Features

• 1 cubic foot internal volume providing defined acoustic rear cavity for compatible ceiling speakers
• Designed to control rear-wave dispersion and reduce sound bleed into plenum and adjacent spaces
• Sold as a single unit for straightforward per-speaker installation planning
• Intended for commercial and institutional distributed audio installations

Compatibility

Designed as an OEM-style back can accessory for compatible JBL PROFESSIONAL ceiling speakers requiring a rear enclosure; consult system specifications to confirm fitment with the target speaker model.

Installation Notes

Back can enclosures are typically installed by licensed audio-visual contractors or electricians during ceiling speaker rough-in, before ceiling finish work is complete. Confirm that plenum-rated materials and local fire code requirements are met before installation in air-handling spaces. Ensure power to any associated audio equipment is disconnected before making speaker connections. Follow local building and electrical codes throughout installation.
