JBL JRX 225 Passive Loudspeaker

JBL JRX225 — Dual 15" Passive PA Loudspeaker for Live Sound

The JBL JRX225 is a portable, dual fifteen-inch, two-way speaker system engineered for live music performance. Two M115-8A low-frequency drivers work with a 1" polymer diaphragm compression driver on a Progressive Transition™ waveguide, producing full-range output for working DJs, bands, and venue operators. With a maximum SPL of 133 dB and a 500 W continuous / 2000 W peak power rating, vocals and instruments project with authority across large spaces. The Quasi 3-Way topology splits tasks between the two 15" woofers so the upper handles mid-range and bass while the lower focuses solely on bass.

What Sets the JRX225 Apart in the Dual 15" Category

Mid-range clarity often suffers in dual 15" cabinets, but the Quasi 3-Way crossover design here tackles that issue head-on. Edgewound ribbon voice coils — 64 mm (2.5 in) in diameter — allow for more copper in the magnetic gap than round-wire coils, increasing both efficiency and heat tolerance. Protection for the compression driver is ensured by SonicGuard™ circuitry, which operates silently even under sustained overdrive.

Deep, Articulate Bass from Dual 15" Woofers

Cabinet tuning enables the two 15" drivers to move air efficiently, turning it into usable low end without muddiness.

• LF Drivers: 2 × M115-8A, 15" — the dual setup achieves higher SPL and bass extension than a single woofer can.
• Voice Coil: 64 mm (2.5 in) edgewound ribbon — more copper cross-section in the magnetic gap compared to round-wire designs.
• Frequency response of 42 Hz – 18 kHz (-10 dB) allows for full-range music without mandatory sub support.

Crisp Highs and Controlled Coverage

Coverage remains consistent across the audience thanks to the combination of compression driver and waveguide.

• HF Driver: 2414H-C, 25 mm (1 in) polymer diaphragm compression driver — proven JBL technology delivers reliable high-output performance.
• Waveguide: Progressive Transition™ — delivers a 90° × 50° dispersion with low distortion.
• Crossover at 2.2 kHz is implemented with advanced network topology for smooth driver integration.

Headroom and System Integration

This cabinet achieves 133 dB maximum SPL and 100 dB sensitivity (1 W / 1 m), so it can play loud with only moderate amplifier power. Nominal impedance of 4 ohms and a recommended amplifier range of 500–1000 W allow compatibility with most pro amps.

• Maximum SPL: 133 dB — peak output for live and DJ events.
• Power Rating: 500 W continuous / 2000 W peak — easily handles program material and dynamic peaks.
• Daisy-chaining is made simple with Neutrik® Speakon® NL-4 and 6.35 mm (1/4") TS parallel inputs.

Ideal Applications for the JRX225

This model is ideal for DJs, mobile entertainers, houses of worship, and small-to-mid venue operators who need a passive loudspeaker on a single 4-ohm amp channel. Solo performers benefit from vocal clarity without subs, and bands get the headroom needed for full drum-kit sound. At 42.6 kg (94 lb) and equipped with dual steel handles, the enclosure remains manageable for solo transport between gigs.
