JBL LSR705i 5-Inch 2-Way Master Reference Monitor
The LSR705i is a professional nearfield reference monitor engineered for critical listening in mastering and mixing environments. This is a component-level system designed to integrate into a larger monitoring chain, requiring external signal processing and amplification to operate. Built on decades of JBL professional audio expertise, it delivers the precise, transparent reproduction demanded by experienced engineers and mastering professionals.
Acoustic Design & Transducers
At the heart of this monitor sits a 725G five-inch high-excursion woofer paired with a 2409H compression driver for midrange and treble reproduction. The patent-pending Image Control Waveguide ensures a seamless crossover transition at 1.9 kHz, minimizing acoustic coloration and maintaining phase coherence across the frequency spectrum—critical for accurate mix decisions.
Performance & System Requirements
The monitor delivers a maximum peak SPL of 107dB, with a frequency range extending from 39Hz to 36kHz, covering the full spectrum of professional audio content. The dividing network can be bypassed for bi-amplified operation, allowing advanced users to run dedicated amplification on the woofer and compression driver separately. This system requires a HARMAN Professional signal processor and external Crown Power Amplifier for operation—it is not designed for stand-alone use.

Frequently Asked Questions
Is the LSR705i a stand-alone monitor I can plug directly into my interface?
No. The LSR705i is a component-level system requiring both a HARMAN Professional signal processor and external Crown Power Amplifier to operate. It is not designed for stand-alone use and cannot be connected directly to an audio interface.
What makes the LSR705i different from typical studio monitors?
The LSR705i uses a patent-pending Image Control Waveguide and 1.9kHz dividing network to maintain phase coherence and minimize acoustic coloration, ensuring transparent reproduction without adding character. Its 725G high-excursion woofer and 2409H compression driver deliver extended frequency response from 39Hz to 36kHz for comprehensive accuracy across professional audio content.
Can I run this as a bi-amplified system?
Yes. The dividing network can be bypassed to allow dedicated external amplification on the woofer and compression driver separately, giving advanced users flexibility in their amplification architecture.
What is the maximum SPL of the LSR705i?
The LSR705i delivers a maximum peak SPL of 107dB, providing sufficient headroom for professional mixing and mastering environments.
Who should buy the LSR705i?
Professional engineers and mastering specialists who already have signal processing and amplification infrastructure in place and demand transparent, phase-coherent monitoring without coloration. This monitor is not suited for live performance, portable use, or stand-alone operation.
