JBL PROFESSIONAL CONTROL 47C-T - Extended Bass Ceiling Speaker with Consistent Coverage
The JBL Professional Control 47C/T is a high-end ceiling speaker designed to deliver superior audio quality and exceptional performance in commercial installations. This two-way system is sold in pairs and features extended bass response and an exceptionally wide and consistent 120° conical coverage. This uniform dispersion allows for sound reinforcement in large spaces with fewer speakers, optimizing both installation costs and the aesthetics of the space without sacrificing sound quality. Its sleek and discreet design blends seamlessly into any décor, making it the preferred choice for audio professionals.
The core of its acoustic performance lies in JBL's patented Conical Radiation Boundary Integrator® (RBI™) technology. This innovation consists of a large tweeter waveguide that is coaxially integrated with the woofer. The result is a seamless transition between high and mid frequencies, eliminating the off-axis sound variations that occur in other speakers. This ensures that every listener, regardless of their location in the room, experiences clear, intelligible, and balanced sound. Furthermore, its large back can is specifically designed to deliver a deep and rich bass response, reaching down to 55 Hz.
Built with high-quality materials, the Control 47C/T features a 165mm (6.5-inch) woofer with a polypropylene cone and a durable butyl rubber surround, and a 25mm (1-inch) ferrofluid-cooled soft dome tweeter. This combination ensures not only accurate, low-distortion sound reproduction but also a long lifespan and reliability, even in high-humidity environments. Its versatility is another key strength, as it can operate in both low-impedance (8-ohm) systems and 70V/100V distributed lines, thanks to its integrated 60W multi-tap transformer.
