JBL Control 447HC 6.5 IN PREMIUM HC CEILING SPKR

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 recording studios, post-production facilities, and acoustically treated spaces. 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 rooms without occupying visible real estate or interfering with studio geometry.

Acoustic Performance & Monitoring Accuracy

This speaker achieves 93 dB sensitivity with a rated maximum SPL of 113.5 dB continuous and 119.5 dB peak at 1 meter, enabling clean, detailed reproduction during tracking, overdubs, and mastering sessions. The 85° conical coverage angle and RBI™ (Radiation Boundary Integrator) technology ensure predictable, uniform sound dispersion that minimizes phase issues and dead zones, critical for accurate monitoring in ceiling-mounted or distributed studio configurations.

Flexible Integration into Studio Signal Chains

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 simplifying multi-room monitoring or satellite speaker setups. The zinc-plated C-ring, tile rails, and 307 mm cutout specification allow rapid installation into standard T-bar or drywall ceilings, while the paintable magnetic grille integrates seamlessly with studio finishes and acoustic treatments.
