JBL-C447C/T-U

The JBL‑C447C/T‑U is a professional two‑way in‑ceiling loudspeaker from JBL’s Control 400 Premium Coverage Series. It combines a coaxially mounted 6.5‑inch woofer and a 1‑inch soft‑dome tweeter with JBL’s proprietary Radiation Boundary Integrator (RBI) technology to deliver wide, consistent coverage and clear full‑range sound. The speaker is designed for commercial and professional installations such as retail spaces, offices, schools, and hospitality environments. It includes an integrated enclosure and mounting system that simplifies installation in standard ceiling plenum spaces while offering flexible deployment with either low impedance or distributed 70V/100V audio systems.
