JBL SRX715 Professional Loudspeakers (Pair)

The JBL SRX715 is a highly respected, high-power, two-way passive loudspeaker from JBL’s professional series, designed for portable and installed sound reinforcement applications. It’s renowned in the live sound industry for delivering excellent performance in a relatively lightweight package.

Descriptions

1. High Power & Sensitivity: The SRX715 boasts a substantial power rating (Passive: 800 W Continuous / 3200 W Peak), capable of producing an impressive maximum peak Sound Pressure Level (SPL) of 131 dB. Its high sensitivity of 96 dB means it can get very loud and dynamic without demanding the absolute maximum from its amplifier.

2. Lightweight Design: Despite its high power and large 15” driver, the SRX715 weighs only 22 kg 48 lbs. This portability is achieved through the use of high-efficiency neodymium magnets in both the woofer and the compression driver.

3. Differential Drive Technology: It utilizes the patented JBL 2265H Differential Drive 15” woofer. This design uses dual voice coils and dual magnetic gaps to provide high output and high power handling while significantly reducing the speaker’s weight.

4. Flexible Operation (Bi-amp/Passive): A recessed switch on the input panel allows the user to select between:

   • Full-Range Passive Mode: The speaker’s internal crossover handles the frequency splitting, simplifying setup with one amplifier channel.

   • Bi-amplified (Bi-amp) Mode: Allows separate amplifier channels to drive the Low-Frequency (LF) and High-Frequency (HF) drivers, offering greater control, efficiency, and dynamic range.

Key Specifications

• Type: 15″ two‑way bass‑reflex loudspeaker
• Woofer: JBL Differential Drive® 15″ woofer with neodymium magnet (lightweight, high‑power capacity)
• Compression Driver: 3″ voice‑coil neodymium compression driver for clear highs
• Power Handling: 800W RMS / 3,200W peak
• Coverage Pattern: 75° × 50° horn for even sound distribution
• Operation Modes: Can be used bi‑amplified or full‑range passive

Design & Build

• Cabinet: Rugged birch plywood construction with JBL’s DuraFlex™ finish for durability
• Weight: Lightweight design makes it easy to transport and mount
• Mounting Options:
  • Dual‑angle pole socket for tripod mounting
  • Flying version (SRX715F) with five suspension points for rigging
• Internal Bracing: Reduces acoustic losses caused by panel resonance

🎶 Applications

• Live Sound Reinforcement: Ideal for concerts, DJ setups, and touring rigs
• Speech & AV Events: Clear vocal reproduction for conferences and presentations
• Satellite Speaker: Can be paired with subwoofers (e.g., JBL SRX718S) for extended low‑frequency response

⚡ Why It Stands Out

• High Output with Low Weight: Thanks to neodymium drivers and Differential Drive technology
• Flexible Use: Works as a standalone speaker or part of a larger PA system
• Durability: Built to withstand professional touring and rental environments

🎯 Common Applications

The SRX715 is a versatile workhorse frequently used for:

• Main PA Speakers: For small to medium-sized events, clubs, and houses of worship.

• High-Performance Monitors: Due to its clear sound and robust build, it is also highly effective as a high-power floor monitor.

• Satellite Speaker: Often used over matching SRX-series subwoofers (like the SRX718S) to create a powerful, scalable concert system.
