JBL 3733-M/HF Mid-High Section Only – Cinema ScreenArray
The JBL 3733-M/HF is the mid and high-frequency horn block component of JBL Professional's 3733 ScreenArray, built for cinema installations behind perforated screens. This pre-assembled section delivers precise directional control and consistent coverage across the mid and treble spectrum, designed to integrate with the separate 4739 low-frequency cabinet for a complete three-way system.
Coverage & Frequency Response
The 3733-M/HF section provides 100-degree horizontal coverage with asymmetrical vertical directivity via Dual Dissimilar Arraying technology, ensuring even acoustic distribution across theater seating. Paired with the 4739 LF section, the complete 3733 system spans 40 Hz to 19 kHz (−3 dB), delivering full-range cinema sound.
Components & Power Handling
The horn block houses 2× 165H 165 mm (6.5-inch) midrange drivers with 38 mm voice coils and 2× 2415-XP high-frequency compression drivers, all wired to a nominal impedance of 12 ohms. The M/HF section handles 300 W of input power and integrates into a bi-amplified configuration that demands separate amplification for the bass cabinet.

Frequently Asked Questions
What does B-Stock mean for this product?
B-Stock means the 3733-M/HF is fully functional and meets all performance specifications, but may have minor cosmetic imperfections such as small dents, scratches, or wear marks that do not affect operation or sound quality.
What do I need to buy separately to use this component?
You must purchase the JBL 4739 low-frequency cabinet separately, plus dedicated bi-amplified amplification and cinema processing to complete the 3733 ScreenArray system. The 3733-M/HF section alone cannot operate as a standalone speaker.
What venues and installations is this designed for?
This component is engineered specifically for permanent cinema installations, theaters, and commercial AV applications where speakers mount behind perforated screens. It is not suitable for live touring, portable PA systems, or small venues.
What is the frequency coverage of the mid-high section?
The 3733-M/HF section handles the midrange and treble spectrum; when paired with the 4739 LF cabinet, the complete system spans 40 Hz to 19 kHz (−3 dB). The M/HF section itself covers 100 Hz to 19 kHz with 100-degree horizontal coverage and asymmetrical vertical directivity.
How much power does the M/HF section require?
The mid-high section handles 300 W of input power at a nominal impedance of 12 ohms and is configured for bi-amplified operation, meaning it requires its own dedicated amplifier channel separate from the low-frequency cabinet.
Do I pay sales tax on this order?
Sales tax is collected only on orders shipped to California; orders shipped to any other US state are not charged sales tax at checkout when you buy direct from our website. At a typical 7% rate that is an estimated $198 less at checkout than the same listed price on a marketplace, which collects sales tax as the facilitator in most states. Buyers remain responsible for any use tax their state applies. Free US shipping and 30-day returns are included.
