JBL Professional 3730-M/HF (3730-M-HF) - Midrange/Treble Module for ScreenArray 3730 Home Theater System

The JBL Professional 3730-M/HF (also referred to as the 3730-M-HF ) is the midrange and tweeter section of the ScreenArray 3730 behind-screen cinema system. It features a 165 mm 195H midrange driver (38 mm voice coil) and a 25 mm 2414H compression driver with neodymium magnet and polymer diaphragm, mounted on a flat-front Optimized Aperture waveguide for easy baffle wall mounting. With a sensitivity of 105 dB (2.83 V/1 m) , a nominal impedance of 4 Ω (MF 8 Ω / HF 8 Ω), and a power output of 125 W AES , it delivers even coverage, low distortion, and a smooth transition to the 3739 LF section, maintaining the sonic character of the ScreenArray family in small to medium-sized venues.

Main features

• M/HF set for the JBL ScreenArray 3730 system, designed to work behind a micro-perforated screen.
• Transducers: 1 × 195H 165 mm (6.5") / 38 mm voice coil; 1 × 2414H 25 mm (1") HF with polymer diaphragm and neodymium motor.
• Molded Optimized Aperture waveguide with flat front for acoustic wall integration and directivity control.
• Free-field sensitivity: 105 dB (2.83 V/1 m); sensitivity per channel: MF 104 dB / HF 106 dB.
• Impedances: MF 8 Ω; HF 8 Ω; M/HF set 4 Ω (minimum 3 Ω @ 1850 Hz).
• Nominal power: 125 W AES (2 h) for the M/HF module.
• Connectivity: terminal strip ( screw terminal barrier strip ).
• Compact and lightweight format: 852 × 762 × 360 mm; 11.1 kg.
• Full compatibility with the LF 3739 (double 15") section of the 3730 system.

Product benefits

• Clear reproduction of dialogue and effects with low distortion thanks to the 2414H motor and waveguide control.
• Consistent coverage in the seating area and compensation for the spread caused by perforated screens, while preserving intelligibility.
• High efficiency (105 dB) to achieve reference levels with less amplification power.
• Easy installation on a baffle wall due to its flat front and contained depth of the assembly.
• Simplified service and maintenance by being able to replace the M/HF section without replacing the entire system.

Use cases

• Replacement of the M/HF module in existing JBL ScreenArray 3730 systems.
• Projects for new small and medium-sized movie theaters that adopt the 3730 tri-amplified, bi-amplified, or passive system.

Integration Notes

• The 3730 system offers bi-amped or passive operation with the option of tri-amping depending on the processing design.
• Reference crossover frequencies (3730 system): 450 Hz and 2 kHz. Adjust the processor/crossover according to the manufacturer's specifications and the room's acoustic design.
• Nominal system coverage (with 3730-M/HF): 90° (H) × −30°/+20° (V).
