JBL Control 328C 8" Coaxial 2-WAY Ceiling Loudspeaker

JBL Control 328C 8" Coaxial 2-Way Ceiling Loudspeaker

The Control 328C is a coaxial ceiling speaker engineered to capture and reproduce consistent, intelligible sound across medium-sized spaces. Its compact round baffle installs flush into standard ceiling cavities, delivering controlled dispersion without the acoustic compromises of conventional point-source designs. Built to professional standards, this speaker handles both dialogue clarity and music playback with precision—ideal for recording studio control rooms, streaming facilities, and monitoring applications where phase coherence and flat response matter.

Audio Performance & Frequency Response

The coaxial design places a 25 mm compression driver at the acoustic center of a 200 mm Kevlar-reinforced woofer, ensuring tight phase alignment and smooth tonal continuity throughout the mix. Coverage spans 45 Hz to 18 kHz (−10 dB), with a 120° broadband pattern control that maintains even SPL across the listening area—essential for accurate monitoring and critical listening where room modes and dead zones compromise mix decisions.

Construction & Installation

The speaker features a metal, round baffle with a ported design and drivers pre-mounted for fast installation. The high-frequency driver uses a pure titanium diaphragm with diamond surround and FerroFluid cooling, ensuring reliability under continuous monitoring sessions and extended recording workflows. A removable multi-pin locking connector with screw-down terminals simplifies both setup and future service when reconfiguring studio architecture.
