The JBL SRX725 is a dual 15-inch, two-way professional loudspeaker engineered for high-output live sound reinforcement, delivering powerful bass, clear mids, and crisp highs in a rugged touring-ready enclosure.
What is the JBL SRX725
-
The SRX725 is a professional-grade, passive 2-way loudspeaker (dual 15″) — designed for live sound reinforcement, concerts, PA systems, events, clubs, venues, and other high-output audio applications.
-
It belongs to the “SRX Series” from JBL — built for power, durability, and reliable performance under demanding conditions (touring, live shows, installations).
-
Extreme Power Handling: The SRX725 has a massive power rating of 1200W Continuous 2400W Program 4800 W Peak in passive mode.8 This allows it to achieve an impressive maximum peak Sound Pressure Level (SPL) of 136 dB.
-
Dual 15” Differential Drive Woofers: It features two patented JBL 2265H Differential Drive 15” woofers. This technology uses dual voice coils and neodymium magnets to maximize power handling and lower the speaker’s weight significantly (the unit weighs only 45 kg 100 lbs). The dual 15” design provides strong, extended low-frequency output down to 37 Hz (-10 dB).
-
High-End Compression Driver: The high frequencies are handled by a legendary JBL 2451H 4” voice-coil neodymium compression driver, which is mounted to a 75×50 aluminum horn, ensuring smooth, clear mids and highs with wide, controlled coverage.
-
Bi-Amp / Passive Selectable: A recessed switch on the input panel allows the user to select between:
-
Full-Range Passive Mode: Simplifies setup using a single amplifier channel (at 4 Omega).
-
Bi-Amplified Mode: Separates the LF and HF drivers for dedicated amplification, offering greater efficiency, dynamic range, and precision control via an external crossover (recommended for maximum performance).
-
-
Durable and Flyable: The enclosure is constructed from top-quality 15mm (11-ply) birch plywood with JBL’s rugged DuraFle finish. A flying version (SRX725F) is available, which includes five suspension points for M10 eyebolts for installation.

Features & Capabilities
-
The speaker handles 800 W continuous, 1600 W program, and 3200 W peak power enough to provide loud, clean sound even in large venues.
-
It uses a 15-inch Differential Drive woofer (with neodymium magnet + dual voice-coils) for solid bass and low-end, plus a 3-inch (75 mm) compression driver for clear highs.
-
Frequency response is roughly 53 Hz to 20 kHz (±3 dB), with extended range down to ~43 Hz at –10 dB — so it covers bass, mids, and highs fairly well.
-
The built-in horn offers a nominal coverage of 75° × 50°, making it suitable for broad audience coverage without sharp drop-offs.
-
You can run it in full-range passive mode (single amplifier) or bi-amplified mode (separate amps for low and high frequencies), whichever suits your setup.
-
Despite its power, the enclosure is built from birch plywood (light but sturdy), and the speaker weighs ~22 kg (≈ 48 lb). It includes a dual-angle pole socket for tripod/pole mounting (vertical or 10° down tilt), making it convenient for live gigs, clubs, events.
-
Finished with JBL’s rugged “DuraFlex” coating, with a powder-coated steel grille (with foam backing) to protect drivers — promising durability during transport, gigs, and rough usage.

Key Features
-
Power rating: ~ 140 W (per pair, or system spec depending on listing).
-
Frequency response: ~ 45 Hz – 20 kHz — so it reaches decently low bass for a bookshelf / compact speaker.
-
Woofer / bass driver size: 250 mm — that’s roughly a 10-inch class driver, giving decent bass presence.
-
Tweeter: ~ 25 mm (about 1″) dome/tweeter for highs.
-
Impedance: 4–8 Ω nominal, which means you’ll want a decent amplifier that can drive lower-impedance loads well.
-
Sensitivity: ~ 90 dB — relatively high sensitivity, meaning the speakers efficiently turn amplifier power into loud sound.
-
Physical size / weight: Each speaker is fairly large for a “bookshelf” — roughly 306 mm (height) × 504 mm (width) × 263 mm (depth), and about 12 kg per unit.
