EMB Professional ESM6 1-Inch Compression Tweeter

The EMB Professional ESM6 is an 8-ohm compression tweeter driver designed for replacing a failed high-frequency driver in compatible horn-loaded loudspeakers. It uses a 1-inch throat format and a threaded 1-3/8-inch mounting connection for matching horn assemblies. This is a high-frequency component, not a full-range speaker.

The ESM6 is intended for PA-style cabinets, DJ speakers, and similar systems that use a separate horn for upper-midrange and treble reproduction. Its stated 1.2 kHz to 20 kHz frequency range supports high-frequency output when it is installed behind an appropriate crossover. It can be useful when restoring a cabinet whose original driver shares the required mounting, throat, and impedance specifications.

With a stated maximum power handling of 700 watts, the ESM6 is built for systems that need a replacement compression-driver-style tweeter. The published figure is a maximum-power rating; an RMS power rating is not specified. Proper high-pass filtering is important to prevent damaging low-frequency energy from reaching the driver.

The driver has an 8-ohm impedance, allowing it to match compatible 8-ohm high-frequency crossover sections. Its single-voice-coil configuration keeps the replacement layout straightforward for applicable speaker repairs. Verify the original driver impedance and crossover design before selecting it as a substitute.

The ESM6 is listed for use in certain JBL, Peavey, Cerwin Vega, Gemini, EMB, BMB, Pyle-Pro, and Mr. DJ speaker applications. Brand compatibility alone does not confirm fit, because horn thread, throat diameter, wiring, and crossover requirements can vary by cabinet. It is best suited to repair or upgrade projects where those mechanical and electrical requirements have been checked first.

Key Features

• 1-Inch Throat: Fits compatible horn assemblies using a 1-inch driver throat.
• 8-Ohm Impedance: Supports replacement planning for compatible 8-ohm high-frequency networks.
• 700W Maximum Power: Provides the manufacturer's stated maximum power-handling figure.
• 1.2 kHz–20 kHz Range: Covers the stated upper-midrange and high-frequency operating range.
• Single Voice Coil: Uses a simple single-coil compression-driver configuration.
• 1-3/8-Inch Threaded Mount: Connects to compatible threaded horn assemblies.

Design & Installation

The ESM6 uses a compact compression-driver-style design with a 1-inch throat and threaded 1-3/8-inch mounting interface. It is built as a separate horn driver for the high-frequency section of a speaker system. Confirmed product information does not specify the diaphragm material, magnet material, sensitivity, or driver weight.

Install the ESM6 only on a compatible threaded horn and connect it through a correctly configured high-pass crossover. Check the original driver's impedance, throat size, mounting thread, terminal polarity, and crossover point before installation. Do not connect this driver directly to a full-range amplifier output without suitable high-pass protection.
