JBL 5749 Dual-18 LF Bass Section Only (HPD5749) - for 5742 ScreenArray

JBL 5749 Dual-18 LF Bass Section (HPD5749)

The JBL 5749 is the low-frequency foundation of the 5742 ScreenArray system, engineered to deliver controlled, articulate bass extension for recording studios, mixing facilities, and production environments demanding cinema-grade low-end accuracy. This is the bottom cabinet only—a purpose-built bass section designed to integrate with the 5742-M/HF mid and high-frequency top section, sold separately. Built on JBL's cinema-grade LF architecture, the 5749 combines dual 18-inch drivers with professional-grade cooling and voice-coil engineering for reliable, consistent performance during extended tracking and monitoring sessions.

Driver & Impedance Specifications

Two 2242HPL Super Vented Gap Cooled 460 mm (18-inch) woofers with 100 mm edgewound ribbon voice coils are wired in parallel to achieve a nominal impedance of 4 ohms (minimum 3.36 ohms at 27 Hz). This configuration ensures stable, predictable amplifier loading and maximizes power transfer across the operating range, providing the foundation for tight, controlled low-end that translates across mix environments.

Power Handling & Sensitivity

Rated for 1600 W input power handling (72 V), the 5749 delivers 104 dB SPL sensitivity (2.83 V / 1 m), enabling efficient high-output monitoring and reference playback in control rooms and tracking spaces without excessive amplifier headroom. The cabinet's vented-gap cooling design maintains consistent driver performance during sustained sessions and long monitoring periods.
