3733
Three-Way Bi-Amplified ScreenArray® Cinema Loudspeakers
SPECSHEET
Description:
For critical sound reproduction in cinemas utilizing a solid screen. The 3733 uses the 4739
LF for increased low frequency output. The M/HF utilizes Dual Dissimilar Arraying technology
to optimize the coverage pattern for rooms with raked seating. In addition, the horn design
improves the frequency response and lowers distortion at higher output levels. The 2415-XP
high frequency drivers represent JBL’s latest HF compression driver, designed to achieve
higher output with lower harmonic distortion.
Key Features:
• Three-way ScreenArray® design for maximum output, optimal coverage and minimum
distortion
• Dual Dissimilar Arraying technology to improve high frequency coverage in rooms with
raked seating
• JBL 2415-XP next-generation high frequency compression driver
• Advanced waveguide design for improved frequency response and higher output with
lower distortion
• Used in conjunction with CRF2 reflector horns, which are used to reflect high frequency
content off a solid screen
• Includes the same HF driver as the CRF2 to maintain tonal quality
• Supports bi-amp configuration only
