Frequently asked questions
Which backcan works with which JBL speaker?
The MTC-200BB6 is engineered specifically for the Control 227C and 227CT speakers. The MTC-300BB8 is designed for 8-inch Control 300 series drivers. Using the wrong backcan with a speaker will degrade acoustic performance.
What is the main acoustic difference?
The MTC-300BB8's larger internal volume (0.71 cu ft vs 0.5 cu ft) and bigger enclosure enable extended bass response from the larger 8-inch driver. The MTC-200BB6 is optimized for speech clarity and controlled midrange with the smaller 227 series speakers.
Do I need U.L. certification for my installation?
The MTC-300BB8 carries U.L.-2043, U.L.-1480, NFPA90, and NFPA70A certifications for plenum-rated and air-handling spaces. The MTC-200BB6 specifications do not list these certifications. If your ceiling is part of an air-handling return plenum or regulated environment, the MTC-300BB8 is the required choice.
Which fits standard drop ceilings better?
The MTC-300BB8 specifies a 310 mm (12.2 inch) ceiling cutout designed to integrate into standard drop-ceiling grids. The MTC-200BB6's 13.3-inch diameter is slightly smaller but less explicitly optimized for grid compatibility.
