The 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 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 47LP is switchable
for use as either an 8-ohm low-impedance speaker, or as part of a
70V/100V distributed loudspeaker system
