JBL Professional Control 227CT - 6.5″ Coaxial Ceiling Speaker with HF Compression Driver and 70/100V Multi-Outlet Transformer
The JBL Professional Control 227CT is a 6.5" coaxial ceiling loudspeaker designed for professional installations that demand superior sound quality and uniform coverage. Its 120° constant directivity pattern reduces the number of points required without sacrificing intelligibility, while the combination of a 165mm Kevlar-reinforced woofer and a 25mm compression driver delivers exceptional clarity for both speech and music. It features a multi-tap transformer for 70/100V distributed lines and can operate at low impedance (8 Ω) via bypass , facilitating its integration into new projects and renovations with various amplification topologies.
The Control 227CT is designed for use with pre-assembled back cans and grilles (accessories), ensuring compliance in plenum/air handling spaces . The 305 mm diameter metal baffle comes with the transducer already installed to expedite installation. Official accessories include the MTC-200BB6 back box (cylindrical, 16-gauge steel with MDF lining) and the MTC-RG6/8 (round) or MTC-SG6/8 (square) grilles, along with the MTC-TB6/8 for modular suspended ceilings.

Frequently Asked Questions
-
Does it include a back box and grille? No. They are purchased separately (e.g., MTC-200BB6 and MTC-RG6/8 or MTC-SG6/8 grilles).
-
Is it suitable for plenum mounting? Yes, when installed with a UL-listed backcan (e.g., MTC-200BB6 or MTC-300BB8) and in accordance with applicable regulations.
-
Can it be used at 8 Ω? Yes. It has an 8 Ω bypass mode in addition to the 70/100 V sockets.
