Fill large rooms with consistent, intelligible audio using a ceiling speaker designed for commercial distributed sound. JBL Control 328CT pairs an 8 in coaxial architecture with a pre-attached 60 W 70V/100V multi-tap transformer, giving integrators the flexibility to match output to the room and the amplifier design. The transformer taps at 68 W, 34 W, 17 W, and 8.5 W at 70V only support practical zoning across offices, hospitality areas, retail floors, and education spaces. That flexibility matters when one installation has to cover different acoustics, ceiling heights, and listening priorities without overbuilding the system. Its 12 in round ported baffle with waveguide is engineered to support controlled dispersion and cleaner off-axis performance, helping speech stay intelligible while music remains balanced. UL listing adds confidence for commercial projects where compliance and installation discipline are part of the spec. Priced as a one-pack containing 2 pieces, this model is a strong fit for teams that want a ceiling loudspeaker with the output structure and installation flexibility expected in higher-value commercial audio projects.
