JBLControl 47C/T

Two-Way 6.5" Coaxial Ceiling Loudspeaker with Extended Bass




Two-Way 6.5" Coaxial Ceiling Loudspeaker with Extended Bass

            The Control 47C/T is a premium inceiling professional loudspeaker designed for applications that require extremely wide bandwidth along with very consistent coverage.

            Featuring JBL’s exclusive conical Radiation Boundary Integrator® (RBI™), the RBI provides a large waveguide for the tweeter while low-frequency sound projects through specially-designed apertures in the RBI, allowing for a seamless integration of coverage between the two coaxiallymounted drivers. The result is extremely consistent sound character with very little variation throughout the listening space. The wide coverage allows for the use of fewer loudspeakers compared to speakers with less consistent coverage control, while at the same time providing better coverage of the area.

            The large backcan on the Control 47C/T, along with the LF driver design, provides extended bass response for a warm fullbodied tone. The system’s 165 mm (6.5 in) woofer features a polypropylene cone and pure butyl-rubber surround for long life. The copper-clad aluminum voice coil wound on a vented aluminum former provides low distortion and high sensitivity. The coaxially mounted 25 mm (1 in) soft dome features internal damping for smooth extended response and ferrofluid cooling for enhanced power handling and reduced power compression. The result is crisp, clear highs.

            Ideal for small and large projects alike, the Control 47C/T is switchable for use as either an 8-ohm low-impedance speaker, or as part of a 70V/100V distributed loudspeaker system.

Features

·       Extremely consistent 120° broadband pattern control featuring JBL’s exclusive conical Radiation Boundary Integrator® (RBI™) technology.

·                   Provides very consistent coverage of listening area.

·                   Wide coverage requires fewer speakers, reducing the cost of the installed system without sacrificing performance.

·       Coaxial design featuring:

·                   165 mm (6.5 in) woofer with butyl rubber surround.

·                   25 mm (1 in) soft-dome tweeter on 250 mm (10 in) diameter wave guide.

·       Bass extension to 55 Hz.

·       8 ohm and 70V/100V operation.

·       Integrated backcan for easy “blind-mount” install. Packaged with grille and tile rails for easy installation.
