JBL Control 447HC 6.5 IN PREMIUM HC CEILING SPKR
Description
JBL Control 447HC 6.5" Premium High-Coaxial Ceiling Speaker
The Control 447HC is a professional-grade ceiling speaker engineered for even coverage and consistent intelligibility in commercial installations. Its coaxial design integrates a 6.5" woofer and 1" tweeter into a compact form factor that mounts flush with standard ceiling dimensions, delivering controlled directional output across medium-to-large spaces without occupying visible real estate.
Acoustic Performance & Coverage
This speaker achieves 93 dB sensitivity with a rated maximum SPL of 113.5 dB continuous and 119.5 dB peak at 1 meter, ensuring clear, punchy reproduction in noisy or high-ambient venues. The 85° conical coverage angle and RBI™ (Radiation Boundary Integrator) technology deliver predictable, uniform sound dispersion that minimizes phase issues and dead zones—critical for reliable performance across installed speaker arrays in live sound or permanent installation contexts.
Installation Flexibility & System Integration
The speaker accommodates both 70V and 100V constant-voltage transformer taps (60W, 30W, 15W, and 7.5W options), eliminating the need for separate transformers and streamlining multi-zone or daisy-chain setups. The zinc-plated C-ring, tile rails, and 307 mm cutout specification enable quick installation into standard T-bar or drywall ceilings, while the paintable magnetic grille blends into any venue or install environment.

Frequently Asked Questions
What does the RBI coaxial design do?
RBI (Radiation Boundary Integrator) technology integrates the 6.5" woofer and 1" tweeter into a single coaxial point source, delivering uniform 85° conical coverage that minimizes phase issues and dead zones across the listening area. This ensures predictable sound dispersion without requiring multiple speakers or complex aiming in medium-to-large spaces.
Do I need a separate constant-voltage transformer?
No. The Control 447HC has built-in 70V and 100V transformer taps (60W, 30W, 15W, 7.5W options), so you can wire it directly into a constant-voltage distributed system without external transformers.
How loud can this speaker get?
The speaker delivers 93 dB sensitivity with a continuous SPL of 113.5 dB and peak SPL of 119.5 dB at 1 meter, making it suitable for noisy or high-ambient commercial environments like retail, hospitality, and offices.
What ceiling types does it mount to?
It installs into standard T-bar or drywall ceilings using a zinc-plated C-ring and tile rails, with a 307 mm cutout specification for rapid flush mounting. The paintable magnetic grille allows finishing to match interior décor.
Is this speaker suitable for live sound or studio monitoring?
No. The Control 447HC is optimized for fixed commercial installations and speech intelligibility, not live performance or critical studio work. Its ceiling-mounted position and commercial tuning make it unsuitable for stage monitoring or close-field mixing.
