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 recording sessions and on-location tracking while maintaining the robust construction needed for reliable performance in demanding studio and field applications.
Recording & Mix Performance
Dual 15″ woofers paired with a 1″ compression driver produce 100 dB SPL sensitivity and peak output of 134 dB SPL, translating to accurate monitoring and reference playback across vocal takes, instrument sessions, and full mixes. The 61 Hz – 16 kHz frequency response (±3 dB) with low-end extension to 48 Hz (–10 dB) ensures tight bass articulation and full-range clarity, allowing you to catch mix decisions with confidence without sacrificing punch in the low end.
Cabinet Construction & Durability
The enclosure features birch/poplar multi-laminate plywood construction with DuraFlex™ finish to withstand the rigors of repeated transport between locations and studio moves. A heavy-duty 16-gauge perforated steel grille with acoustic screen backing protects components while the SonicGuard™ protection safeguards the high-frequency driver from over-excursion during high-SPL monitoring or playback sessions.
