Description
JBL PRX425 15" Two-Way Loudspeaker System
The PRX425 is a compact yet powerful two-way cabinet that delivers extended low-frequency response without requiring a separate subwoofer. Its 74 lb frame makes it portable enough for mobile rigs while maintaining the robust construction needed for reliable performance in demanding live sound applications.
Live Sound Performance
Dual 15" woofers paired with a 1" compression driver produce 100 dB SPL sensitivity and peak output of 134 dB SPL, cutting through any room with clarity and punch. The 61 Hz – 16 kHz frequency response (±3 dB) with low-end extension to 48 Hz (–10 dB) handles guitar, bass, vocals, and full-range playback with tight, articulate bass and transparent highs that stay true to what you're running through it.
Road-Ready Construction
The enclosure features birch/poplar multi-laminate plywood construction with DuraFlex™ finish built to survive the rigors of touring and repeated transport. A heavy-duty 16-gauge perforated steel grille with acoustic screen backing protects the drivers from the realities of touring life, while SonicGuard™ protection prevents the high-frequency driver from over-excursion during demanding sets.

Frequently Asked Questions
What size room or venue works best for the PRX425?
The PRX425 covers clubs to mid-sized venues with its 90° × 50° coverage pattern and 134 dB peak SPL output. Dual 15" woofers and a 1" compression driver deliver full-range sound without requiring a separate subwoofer, making it effective in spaces from small studios to larger live rooms.
Can I power this cabinet with a standard amp, or do I need something specific?
The PRX425 is rated for 600 W continuous, 1,200 W program, and 2,400 W peak at 4 ohms impedance, with dual Neutrik Speakon/¼" TS inputs wired in parallel. Any competent live or studio power amp capable of delivering 600–1,200 W into 4 ohms will drive it reliably.
Does it really replace a subwoofer, or do I still need one?
The dual 15" woofers deliver extended low-end response to 48 Hz (–10 dB) and 61 Hz (±3 dB), providing tight bass articulation and punch across most live and studio applications without a separate sub. For extra-deep bass or very large venues, adding a dedicated subwoofer is optional, but the PRX425 stands alone as a full-range cabinet.
How rugged is this cabinet for touring?
The PRX425 features birch/poplar multi-laminate plywood with DuraFlex finish, a perforated steel grille, acoustic backing, and SonicGuard high-frequency protection. At 74 lb, it balances robust construction with portability, designed to withstand repeated transport and demanding live-sound environments.
