Cinema 3733-M/HF

JBL Cinema 3733-M/HF Professional Cinema Speaker System

The Cinema 3733-M/HF is a three-way cinema-grade loudspeaker designed for serious commercial audio installations where articulate dialogue reproduction and dynamic range are non-negotiable. This is a compact yet powerful system engineered for cinema, auditorium, and large-format commercial environments that demand professional reliability and consistent coverage.

Audio Performance & Coverage

This system delivers 104 dB SPL at 2.83V/1m with individual driver sensitivities reaching 114 dB SPL in the high-frequency section, ensuring commanding output across large venues. The 100-degree horizontal coverage angle at -6dB provides consistent sound throughout the listening area, while dual crossover frequencies at 350 Hz and 1.2 kHz enable seamless blending across the three-way design for transparent midrange and articulate highs.
