Martin Audio LE200 – 15" Passive CDD Stage Monitor

Product Overview

The Martin Audio LE200 is a high-output 15" two-way passive stage monitor built on Martin Audio's Coaxial Differential Dispersion (CDD) driver platform, delivering consistent point-source performance in a low-profile plywood enclosure. Intended for professional live sound and fixed installation environments, the LE200 combines the extended low-frequency output of a 15" LF driver with Martin Audio's controlled Differential Dispersion coverage at artist head-height. A switchable active/passive operating mode provides system designers additional flexibility when integrating the enclosure with iKON amplification and the DX4.0 networked DSP processor.

Product Description

The LE200's Coaxial Differential Dispersion drive unit pairs a 15" (380mm) LF driver with a 3" (75mm) voice coil against a coaxially mounted 1.4" (35mm) exit HF compression driver fitted with a 3" (75mm) pure titanium diaphragm. The CDD configuration ensures both drivers radiate from the same acoustic origin, preserving phase coherence through the crossover region and eliminating the comb-filtering artefacts that arise when LF and HF sources are spatially separated. Martin Audio's Differential Dispersion geometry shapes the combined output into a near-rectangular coverage plane at head-height, concentrating monitor energy along the artist listening arc.

The LE200 supports switchable active and passive operation, giving engineers the choice of passive crossover-driven amplification or active bi-amplified operation with crossover processing handled externally by a compatible DSP processor. M8 rigging inserts allow secure mechanical attachment for touring and permanent installation applications. Multiple input connectors accommodate varied cabling and amplifier configurations, and the low-profile plywood enclosure is suitable for demanding stage environments. When used with the Martin Audio DX4.0 networked loudspeaker processor, the LE200 benefits from comprehensive EQ, delay, and VX limiting to protect the transducers and optimise system alignment.

Key Features

• 15" Coaxial CDD Driver — 3" voice coil LF driver and 1.4" exit HF compression driver share a single acoustic axis for point-source coherence.
• 3" Titanium HF Diaphragm — Pure titanium construction provides extended high-frequency response and low distortion at high SPL.
• Differential Dispersion Technology — Near-rectangular coverage plane at head-height for even energy distribution across the artist monitoring zone.
• Switchable Active / Passive Operation — Configurable for passive crossover or active bi-amp deployment, supporting a range of amplifier and DSP configurations.
• DX4.0 Compatibility — Works with Martin Audio's networked loudspeaker processor for comprehensive system alignment, EQ, and loudspeaker protection.
• M8 Rigging Inserts — Secure mechanical attachment for touring and fixed installation use.
• Multiple Input Connectors — Flexible cabling options for varied system architectures.
• Low-Profile Plywood Enclosure — Durable, stage-ready construction suited to both floor monitoring and install applications.

Typical Applications

• Houses of worship with high-output stage monitoring requirements for live music
• Auditoriums and performing arts centres demanding consistent coverage from floor monitors
• Broadcast studios requiring accurate, high-SPL monitoring for live performance recording
• Multi-purpose rooms and civic venues supporting large-format live production
• Government and institutional spaces with professional stage production infrastructure

Frequently Asked Questions

What is the difference between active and passive mode on the LE200?

In passive mode, the internal crossover network divides the signal between the LF and HF drivers, requiring a single amplifier channel. In active mode, the crossover is handled externally by a DSP processor such as the Martin Audio DX4.0, with separate amplifier channels driving each driver for improved control and loudspeaker protection.

Is the LE200 compatible with the Martin Audio DX4.0 processor?

Yes. The DX4.0's 4-in-8-out architecture and comprehensive DSP suite make it well-suited to managing crossover, EQ, delay, and VX limiting for the LE200 in active bi-amp configurations.

How does the LE200 differ from the LE100?

The LE200 uses a 15" LF driver versus the LE100's 12", providing greater cone area and low-frequency output for high-SPL applications. The LE200 also features a switchable active/passive mode not available on the LE100.

Can the LE200 be permanently installed?

Yes. M8 rigging inserts and a durable low-profile plywood enclosure support permanent installation in auditoriums, houses of worship, and similar venues.

What amplifiers are compatible with the LE200?

The Martin Audio iKON amplifier range is recommended. The IK42 and IK81 both support multi-channel configurations suitable for driving LE200 arrays with full DSP processing via VU-NET software.
