EMB Professional ESM2 1-Inch Compression Tweeter

The EMB Professional ESM2 is an 8-ohm replacement-style compression tweeter driver for compatible PA, karaoke, and sound-reinforcement speaker systems. It is intended for systems using a horn and a 1-inch high-frequency driver throat rather than a conventional flush-mount car-audio tweeter. The threaded rear connection makes fitment verification essential before purchase.

This driver is a practical option for replacing a failed high-frequency component in a compatible speaker cabinet or for completing a custom horn-loaded system. It is marketed for use with compatible applications associated with JBL, Peavey, Cerwin Vega, Gemini, EMB, BMB, Pyle-Pro, and Mr. DJ systems. Brand compatibility alone does not confirm fitment, so the original driver's mechanical and electrical specifications should be compared first.

The ESM2 has a published frequency range of 1.2 kHz to 20 kHz for upper-frequency reproduction in a multi-driver speaker system. Its 8-ohm nominal impedance supports use with compatible high-frequency crossover networks. A properly selected crossover remains necessary to direct only appropriate high-frequency content to the driver.

EMB lists a 450-watt maximum power rating for the ESM2. An RMS or continuous power rating is not published, so the maximum figure should not be treated as a continuous-power specification. Sensible amplifier matching, crossover setup, and level control are important for dependable operation.

The driver uses a 1-inch throat outlet and a 1-3/8-inch threaded mounting screw connection. These dimensions are central to replacement compatibility with an existing horn or cabinet assembly. The ESM2 is a component driver only and is not a complete speaker, horn, crossover, or amplifier package.

Key Features

• 1-Inch Throat: Supports compatible horn assemblies using a 1-inch compression-driver outlet.
• 450W Maximum Rating: Provides EMB's published maximum power-handling figure.
• 8-Ohm Impedance: Matches compatible 8-ohm high-frequency crossover circuits.
• 1.2 kHz–20 kHz Range: Covers the stated upper-frequency operating range.
• Single Voice Coil: Uses a straightforward single-voice-coil driver configuration.
• 1-3/8-Inch Threaded Mount: Connects to compatible threaded horn assemblies.

Design & Installation

The ESM2 is a compact threaded compression-driver design made for horn-loaded high-frequency applications. Confirmed product information identifies its 1-inch throat, 1-3/8-inch threaded mounting interface, and single-voice-coil configuration. Material details for the diaphragm, magnet, housing, and terminals are not published in the confirmed product information.

Before installation, compare the original component's throat size, mounting thread, clearance, and impedance with the ESM2. Connect it through an appropriate high-frequency crossover and avoid using the published 1.2 kHz lower frequency limit as a substitute for crossover design. This driver is best used as a replacement or system-building component where a compatible horn and crossover section are already present.
