Description
The JBL PRX818XLFW is an 18″ powered subwoofer from the PRX800 series with built-in Wi-Fi control. It is designed as the low end of a portable or rental sound system: one unit under a pair of tops, or several for larger events.
Highlights
- JBL 2278H 18″ Differential Drive woofer with dual voice coils, powered by a 1,500 W Class D amplifier.
- 134 dB peak SPL; frequency range 30–103 Hz (−10 dB) and 35–87 Hz (±3 dB).
- Wi-Fi control from the free PRX Connect app for iOS and Android: volume, 8-band parametric EQ and up to 50 ms of delay.
- Two balanced XLR/6.35 mm combo inputs and stereo XLR loop-through outputs with an 80 Hz, 24 dB/octave crossover for the tops.
- dbx Type IV limiter, polarity reverse and a variable-speed fan that only runs when it is needed.
- 18 mm birch/poplar plywood cabinet, DuraFlex finish, 16-gauge steel grille, two handles and an M20 pole socket.
In your setup
Send the left and right outputs of the mixer or DJ controller into the two combo inputs, then take the loop-through outputs to a pair of PRX800 full-range speakers; the selectable 80 Hz crossover keeps the deep bass in the sub. A top can stand on a pole in the M20 socket. With Wi-Fi and the PRX Connect app, the EQ and delay of the sub can be adjusted from anywhere in the venue instead of at the back of the cabinet. The universal power supply accepts 100–240 V, and the cabinet weighs 36.28 kg.
