The JBL Control 47C/T is a high-performance in-ceiling loudspeaker engineered for environments that demand exceptional audio clarity and coverage. Designed for both small and large-scale installations, this professional loudspeaker excels in delivering a wide bandwidth of sound with remarkable consistency.
Central to the Control 47C/T’s performance is JBL’s exclusive Radiation Boundary Integrator® (RBI™) technology. This advanced system features a large conical waveguide that enhances high-frequency dispersion while low-frequency sounds are directed through precision-engineered apertures in the RBI. This design ensures seamless integration between the tweeter and woofer, producing uniform sound quality with minimal variation across the listening area. This consistency allows for fewer loudspeakers to be used, reducing installation complexity while improving overall coverage.
The Control 47C/T’s robust build is complemented by its substantial backcan and LF driver design, which collectively contribute to extended bass response and a rich, full-bodied sound. The 165 mm (6.5 in) woofer is constructed with a polypropylene cone and a pure butyl rubber surround, designed for durability and longevity. The copper-clad aluminum voice coil, wound on a vented aluminum former, ensures low distortion and high sensitivity, translating to clear, accurate sound reproduction.
For high-frequency performance, the Control 47C/T features a 25 mm (1 in) soft dome tweeter. This component benefits from internal damping to provide smooth and extended response. Ferrofluid cooling in the tweeter enhances power handling and reduces power compression, resulting in crisp and clear highs even at high volume levels.
Versatility is a key attribute of the Control 47C/T. It can be used in various configurations, making it suitable for both 8-ohm low-impedance systems and 70V/100V distributed loudspeaker systems. This adaptability ensures that the loudspeaker can be integrated into a wide range of audio setups, from traditional to more complex distributed audio systems.
The Control 47C/T also features an accommodating design for installation. Its large backcan allows for deep bass extension, while the shallow depth makes it ideal for installations in areas with limited mounting space. The loudspeaker’s design ensures it fits seamlessly into ceiling tiles or drywall up to 70 mm (2.75 in) thick, offering flexibility in various building structures.
In terms of construction, the Control 47C/T is built to withstand demanding environments. The speaker is equipped with removable locking 2-pin connectors, ensuring secure and reliable connections. It meets stringent safety and performance standards, including UL1480, UL2043, NFPA90, and NFPA70. Additionally, the loudspeaker complies with IEC60849/EN60849 standards, making it suitable for use in air handling spaces.
Included with the Control 47C/T are essential installation accessories such as a C-ring support backing plate, tile support rails, knockout strain relief, cutout template, paint shield, and removable locking multi-pin connectors. Optional accessories include the MTC-47NC new construction bracket and the MTC-47MR mud-ring construction bracket, providing further flexibility and ease of installation.
In summary, the JBL Control 47C/T is a top-tier in-ceiling loudspeaker that combines advanced technology with practical design features. Its exceptional coverage, robust build, and versatile applications make it an ideal choice for a wide range of professional audio environments.
