JBL Professional 3739 / VTX-V25-VTC - Dual 15" Cinema LF Module and Vertical Transporter for V25 Arrays

This article brings together two professional JBL references intended for different applications in professional audio. On the one hand, the JBL 3739 is the low frequency section used in ScreenArray cinema systems (e.g., 3722/3722N and 3730/3732). It integrates two 380 mm (15") M115H-8A woofers mounted in the 4509 LF cabinet, with a nominal impedance of 4 Ω , 500 W AES power , 104 dB sensitivity (2.83 V/1 m) and a response of 40 Hz to 2 kHz ; it is optimized for behind-screen installation with dimensions of 883 × 762 × 450 mm and a net weight of 65.8 kg.

The JBL VTX-V25-VTC is a vertical transport cart designed for the logistics of VTX V25 series arrays (models V25-II-CS and V25-CS). It allows the vertical transport of 3 or 4 V25 cabinet columns, with heavy-duty brake wheels , a stackable structure for storage and dimensions optimized for standard "truck pack". Its birch plywood chassis with stainless steel/zinc-plated steel fittings measures 291 × 1222 × 635 mm (H × W × D) and weighs 23.6 kg. Both products are independent and not interchangeable : the 3739 is integrated into cinema screens, while the VTX-V25-VTC is a touring accessory for V25 arrays.

Product benefits

For film integrators (3739)

• High level and efficiency in the low-mid band, reducing the power required by the amplifier and maintaining low distortion.
• Guaranteed compatibility with ScreenArray families, ideal for replacing or expanding existing systems.
• Installation behind the screen is facilitated by the depth of the 4509 LF and its optimized geometry.

For touring companies (VTX-V25-VTC)

• Faster and safer logistics when moving complete V25 columns with wheel locks.
• Space-saving in trucks and warehouses thanks to the stackable design and truck pack dimensions.
• Durable professional materials (birch wood and metal hardware) suitable for intensive use.

Use cases

• JBL 3739: Commercial movie theaters and auditoriums with microperforated screens; upgrade from 3722/3722N or 3730/3732 systems.
• VTX-V25-VTC: Tours and events where VTX V25-II-CS/V25-CS arrays are moved in blocks of 3–4 units.

Frequently Asked Questions

• Can the 3739 be used as a standalone subwoofer? No. It's an LF section of a ScreenArray system and requires integration with the system's M/HF path and processing/crossover.
• Which models is the VTX-V25-VTC compatible with? VTX V25-II-CS and VTX V25-CS , in 3- or 4-cabinet stacks.
• Does the VTX-V25-VTC include covers? No. Protective covers (reference VTX-V25-VT-CVR) are supplied separately.
