FBT JMaxX 4000 Active 14" PA Speaker & 18" Subwoofer Package - 4200W RMS
The FBT JMaxX 4000 Active PA Speaker & Subwoofer Package is a cutting-edge solution for high-performance audio in portable and installed sound applications.
Offering a powerful 4200W RMS output, this system is perfect for DJs, bands, live music venues, and event planners. Whether for corporate events, houses of worship, clubs, or rental sound reinforcement, it delivers exceptional sound clarity, punchy bass, and remarkable portability.
At the heart of this package are the FBT JMaxX 114A active speakers. Each speaker boasts a 14" low-frequency woofer with a 2" voice coil and a 1" exit throat HF compression driver with a 1.4" voice coil. With 700W RMS for the LF and 200W RMS for the HF, the JMaxX 114A combines extraordinary power and clarity. The innovative gas-injected moulded polypropylene cabinet not only reduces unwanted resonance but enhances low-frequency performance. With FBT’s latest 90° x 60° HF horn design, this speaker delivers superb projection and precise dispersion of mid and high frequencies, ensuring even coverage across all areas of your venue.
The FBT SUBline 118SA subwoofer is a powerhouse, featuring a robust 18" driver with a 3" voice coil and a peak power of 2400W. Its bass-reflex design, housed in a Baltic birch plywood cabinet, provides deep, punchy bass with a maximum SPL of 137dB. Designed for seamless integration with the FBT JMaxX speakers, the SUBline 118SA offers stereo IN/OUT connectivity, Neutrik TRUE1 power connections, and a built-in DSP with EQ presets for enhanced flexibility and performance.
This active PA package is designed for both ease of use and portability. The FBT JMaxX 114A speakers are lightweight, weighing just 14kg each, yet deliver exceptional 900W RMS output. The compact design of the 14” driver performs like a traditional 15” speaker, making this package an ideal choice for performers who need a balance of power and transportability. The system also features versatile mounting options, including M10 suspension points for installations and built-in 35mm pole mounts for portable setups. Additionally, the JMaxX 114A speakers have multiple wedge angles (14°, 40°, and 55°) for floor monitoring, ensuring clear on-stage sound for performers.
With intuitive rear panel controls, XLR inputs/outputs, volume control, EQ presets, and ground lift switches, the FBT JMaxX 4000 Package allows for straightforward setup and operation.
