JBL 3730 Overview

Designed to accurately reproduce digital cinema soundtracks, the switchable passive/bi-amplified JBL Professional 3730 is a 3-way cinema loudspeaker system that provides superior coverage, maximum power handling, and uniform acoustic power output along with low distortion. The system's wide dynamic range and extended bandwidth reproduce sound exactly as it was recorded.

The low-frequency enclosure features two 15" drivers while the 6.5" mid-driver and high-frequency compression driver are equipped with a molded aperture waveguide, which compensates for high-frequency spreading caused by perforated screens for improved audience coverage. The ScreenArray design provides ideal power response and directivity control with seamless transitions between acoustic sections. The shallow profile of the JBL 3730 is ideal for minimum behind-screen depth requirements.

  • Three-way ScreenArray design for maximum output, optimal coverage, and minimum distortion
  • Bi-amplified or fully passive switchable operation
  • SSC (Screen Spreading Compensation)
  • Molded Optimized Aperture Waveguide technology for low distortion and uniform frequency response
  • Low-frequency section features dual 15” transducers with ribbon wire voice coils for low distortion and high efficiency
  • Flat front waveguide design for easy baffle wall installation
  • Shallow profile for minimum behind-screen depth requirements
