The PRX818XLFW comes loaded with a JBL 2278G 460 mm (18 in) woofer. Differential Drive® technology, JBL's exclusive dual voice coil, and dual magnetic gap design all serve to enhance performance and significantly reduces the drivers’ weight, thanks to an innovative rethinking of the basic elements of loudspeaker design. Eliminating the heavy surrounding steel structure of conventional drivers, the unique construction provides improved heat dissipation while nonlinear distortion is dramatically reduced due to magnetically saturated pole-pieces and an aluminum shorting ring. The glorious results are transparent tone, enhanced frequency response, and increased power output and SPL.
The Next Step in Power Evolution
Driven by a Class-D power amp pushing an impressive 1500 watts, the JBL PRX818XLFW is capable of emitting a Maximum SPL Output of 134 dB peak, with a Frequency Range spanning from 30 Hz - 103 Hz. This abundance of headroom provides enough thunderous bottom to fill the venue with pristine bottom end.
Rugged and Roadworthy
The stackable enclosure is convenient (weighing 80 lbs. lightweight for a sub in this class), yet tough and durable. Constructed of 25 mm (top and bottom for added strength) and 18 mm (back and sides) poplar plywood and assembled utilizing tongue-and-groove joints, the PRX818XLFW is covered in JBL’s protective DuraFlex™ finish, while the components are safeguarded by a dent-resistant 16-gauge steel grille. Thoughtful appointments include lightweight, glass-filled nylon handles, M10 suspension points fabricated from 14-gauge steel (each with a yield-strength of 1000 lbs.), and a pole receptacle capable of accepting SS4-BK or SS4-BK24.
A single GAIN knob controls the input level with an ON/OFF switch for the front LED and a handy POLARITY switch just above it (with its corresponding LED.) There’s a combination 1/4” TRS - XLR input for each of the two channels, and both have an XLR direct THRU with a HI PASS switch and LED placed above them. Up top is the WI-FI CONNECT button (and LED) for WI-FI network configuration using the PRX Connect application. There is also an LED to let you know when the Limiter is engaged and a fan to keep the JBL PRX818XLFW running cool even when the music is hot.
Compatible with HARMAN Connected PA
All PRX800 speakers integrate ioSYS technology to let you control your entire system with one app from just about anywhere in the venue. The convenient setup wizard allows for quick configuration and optimization of speaker levels and EQ.
