JBL PRX425 15" Two-Way Loudspeaker System B-Stock
The PRX425 is a compact yet powerful two-way cabinet engineered to deliver extended low-frequency response without requiring a separate subwoofer. Its portable frame and robust construction make it suited for home studios, project studios, and portable recording setups where full-range monitoring and playback are essential without taking up excessive floor space.
Recording & Monitoring Performance
Dual 15" woofers paired with a 1" compression driver produce 100 dB SPL sensitivity and peak output of 134 dB SPL, delivering transparent monitoring across vocal takes, instrument tracking, and mix playback. The 61 Hz – 16 kHz frequency response (±3 dB) with low-end extension to 48 Hz (–10 dB) ensures tight bass definition and full-range clarity, allowing accurate mix decisions and precise capture of low-frequency instruments without coloration.
Cabinet Design & Construction
The enclosure features birch/poplar multi-laminate hardwood construction with DuraFlex™ finish to withstand repeated studio relocation and transport. A heavy-duty 16-gauge CNC-machined steel grille protects components while the SonicGuard™ protection safeguards the high-frequency driver from excess power without interrupting performance.
