JBL MTC-200BB6 Cylindrical Backcan For Control 227C/CT
Description
JBL MTC-200BB6 Cylindrical Backcan For Control 227C/CT
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.
