Part of the Control 400 collection's Premium Coverage Series, the JBL Control 447HC is a professional in-ceiling loudspeaker designed for applications that require a focused beamwidth pattern along with very consistent coverage. The Control 447HC features a narrow 85° coverage pattern that helps minimize sound reflecting off of room surfaces making it ideal for use in highly reverberant spaces and high ceiling applications. It shares its sonic character with Control 447C/T which allows intermixing of the two models into systems as needed.

It features 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 system's 165 mm (6.5 in) woofer features a treated paper cone and high-performance magnet offering extended bass response for a warm full-bodied tone. The copper-clad aluminum voice coil wound on an aluminum former offers low distortion and high-sensitivity.

Coaxially mounted 25 mm (1 in) cloth soft-dome tweeter with neodymium magnet assembly and aluminum voice coil former provides crisp and clear highs with enhanced power handling.

Control 400 collection's Premium Coverage Series is designed for applications where wide frequency response, superior clarity and high-power handling are required. For applications where more bass is desired, the Control 447HC is tuned to pair well with the Premium Coverage Series Control 440CS/T subwoofer.

The 8Ω impedance allows paralleling up to 2 speakers on a 4Ω capable amplifier. For distributed systems, the ULregistered transformer is designed for exceptionally lowsaturation, even at high drive levels, providing top quality, low distortion distributed sound character.

The stylish bezel-less grille fits seamlessly into a variety of architectural aesthetics. The integrated backcan on the Control 447HC combined with the C-ring support backing plate allows for quick and easy installation of the unit. The included white grille is paintable (grille backing is removeable and re-applicable for painting), and optional accessory grilles are available in black (JBL-MTC-440BG) and in square (JBLMTC-440SG, white only).

The Control 447HC is UL 1480A and UL 2043 listed.
