JBL CONTROL 328C | 8 inch Coaxial Ceiling Loudspeaker with HF Compression Driver

The JBL CONTROL 328C is a top-of-the-line 8 inch coaxial ceiling loudspeaker designed to deliver exceptional audio performance with high frequency (HF) compression driver technology. Engineered from the ground up, this speaker aims to provide a next-generation, point-source audio solution for a wide range of applications.

This advanced ceiling loudspeaker features a consistent 120° broadband pattern control, ensuring an extensive area of coverage with impeccable audio clarity. The unique shaped mounting baffle design equates the pattern control of a 300 mm (12 inch) horn while using a smaller 200 mm (8 inch) driver. This allows for extraordinary clarity in speech and vocals, as well as an extended frequency response that is perfect for music.

With a robust power handling capacity of 250 Watts and high sensitivity, the JBL CONTROL 328C is capable of producing high sound pressure levels (SPL). This makes it highly suitable for large venues, conference rooms, and auditoriums that require precise and clear sound distribution. The advanced high-slope crossover network ensures even coverage and a natural midrange, adding to the overall superior performance of the unit. A clean, contemporary grille and optional backbox complete the design, making this speaker an ideal choice for both form and function.
