JBL Control 47LP Two-Way 6.5″ Coaxial Low Profile Ceiling Loudspeaker, Pair

The JBL Control 47LP is a premium in-ceiling 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 coaxially mounted 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 shallow backcan on the Control 47LP enable the system to be installed into areas with shallow or restricted mounting depths. The Control 47LP’s 165 mm (6.5″) 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″) 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 47LP is switchable for use as either an 8-ohm low-impedance speaker or as part of a 70V/100V distributed loudspeaker system.
