Description
JBL MTC-200BB6 Cylindrical Backcan For Control 227C/CT B-Stock
The MTC-200BB6 is a professional-grade cylindrical backcan engineered for in-ceiling loudspeaker installations where acoustic performance and structural integrity are non-negotiable. This is a purpose-built enclosure designed to maximize the output and reliability of JBL's Control series medium-format speakers in commercial and institutional environments. Built with heavy-duty materials and multiple cable entry points, it handles the demands of permanent installations with straightforward, no-compromise construction.
Acoustic Design & Volume
The 0.5 cubic foot internal volume provides the acoustic compliance needed to optimize the performance characteristics of Control 227C and 227CT loudspeakers. The 0.7 cubic foot nominal external volume ensures proper air movement and prevents cabinet resonance that would degrade speech clarity and frequency response in critical listening applications.
Construction & Installation
Heavy-duty 16 gauge metal construction paired with 12 mm MDF lining creates a rigid, acoustically damped enclosure that resists vibration and handles the rigors of permanent mounting. Five knockouts (one top, four sides) with 22.1 mm diameter openings provide flexible routing for conduit and cable without compromising structural integrity or requiring field modifications.

Frequently Asked Questions
What does B-Stock mean for this backcan?
B-Stock means the MTC-200BB6 is fully functional and meets all performance specifications, but may have minor cosmetic imperfections such as dents, scratches, or finish marks from handling or previous display. The acoustic performance, construction, and compliance certifications are identical to new units.
Which JBL Control speakers does this backcan work with?
The MTC-200BB6 is designed specifically for JBL Control 227C and 227CT medium-format in-ceiling loudspeakers. Its 0.5 cubic foot internal volume is optimized to match the acoustic compliance requirements of those models.
What are the internal and external volumes, and why does that matter?
Internal volume is 0.5 cubic feet and nominal external volume is 0.7 cubic feet. This specific design prevents cabinet resonance, controls air movement, and optimizes the frequency response and output of the mounted speaker for clear speech and audio reproduction.
How flexible is the cable routing during installation?
Five knockouts—one on top and four on the sides—each with 22.1 mm diameter openings allow conduit and cables to be routed without field modifications or compromising the structural integrity of the enclosure.
What makes this backcan suitable for professional installations?
Heavy 16-gauge metal construction with 12 mm MDF acoustic lining creates a rigid, vibration-resistant enclosure that resists resonance and meets U.L., NFPA, and IEC compliance standards required in commercial AV and institutional environments.
