The JBL Control 47LP is an advanced in-ceiling loudspeaker designed for professional audio applications where both exceptionally wide bandwidth and consistent coverage are essential. This speaker excels in environments that require uniform sound distribution and high fidelity, making it a suitable choice for a variety of settings including corporate spaces, retail environments, and educational institutions.

At the heart of the Control 47LP is JBL’s innovative conical Radiation Boundary Integrator® (RBI™). This exclusive technology integrates a large waveguide for the tweeter and uses specially designed apertures for low-frequency sound to ensure a seamless blend between the high and low-frequency drivers. The RBI™ ensures that the speaker delivers a remarkably consistent sound character across the entire listening area, minimizing variations in sound quality and ensuring a balanced auditory experience throughout the space.

The Control 47LP features a wide coverage pattern, which allows for the deployment of fewer speakers compared to models with less effective coverage control. This broad dispersion capability results in more comprehensive area coverage and reduces the need for multiple loudspeakers, thereby simplifying installation and lowering overall system costs. The speaker’s ability to cover a large area with fewer units also contributes to a cleaner and more aesthetically pleasing installation.

One of the notable features of the Control 47LP is its shallow backcan design. This feature enables the speaker to be installed in spaces with limited mounting depth, making it versatile and adaptable to various installation environments. Whether in shallow ceiling voids or restricted spaces, the Control 47LP’s design ensures flexibility without compromising performance.

The loudspeaker is equipped with a 165 mm (6.5 in) woofer that utilizes a polypropylene cone and a pure butyl-rubber surround. This combination enhances durability and extends the lifespan of the driver while providing robust low-frequency response. The woofer’s copper-clad aluminum voice coil is wound on a vented aluminum former, which minimizes distortion and maximizes sensitivity, ensuring clear and accurate sound reproduction.

For high-frequency performance, the Control 47LP features a coaxially mounted 25 mm (1 in) soft dome tweeter. This driver includes internal damping to achieve a smooth and extended high-frequency response. Additionally, the tweeter benefits from ferrofluid cooling, which enhances power handling capabilities and reduces power compression, resulting in crisp and clear high-frequency output.

The Control 47LP is highly versatile, offering switchable operation for either an 8-ohm low-impedance setup or as part of a 70V/100V distributed loudspeaker system. This flexibility allows the speaker to integrate seamlessly into various audio systems, catering to both traditional low-impedance and high-impedance applications.

Overall, the Control 47LP is an ideal choice for both small and large-scale projects, delivering professional-grade audio performance with exceptional coverage and installation flexibility. Its advanced design features and high-quality components make it a reliable solution for demanding audio environments where consistency and clarity are paramount.
