B&C Speakers ME 90

A B&C Horn Designed for Demanding Dispersion Configurations

The ME90 fits within B&C's approach: offering components dedicated to sound reinforcement, designed to integrate neatly into a DIY speaker, a replacement speaker, or a production model. The choice of a constant directivity profile addresses a key need in sound dispersion: maintaining a coherent and intelligible sonic signature over a wide listening area, limiting timbre variations when moving within the coverage zone.

With its compact size and square geometry, this horn easily fits on the front baffle, especially in cabinets where dispersion consistency and ease of installation are priorities. It is a reliable foundation for building or upgrading a high/mid-high section, provided it is paired with a suitable driver and an appropriately chosen crossover.

Who Is the B&C ME90 For?

The B&C ME90 is aimed at integrators, speaker manufacturers, technicians, and DIY enthusiasts looking for a compression horn capable of maintaining consistent coverage in sound reinforcement. It is particularly suitable for systems where projection and control are desired: stage monitors, compact front-of-house speakers, satellites, or vocal/piano/acoustic speakers where intelligibility is a priority.

Thanks to its specified 80 deg horizontal and 60 deg vertical directivity, it helps focus energy toward the useful area (audience, stage) and limits unwanted reflections on walls/ceilings, which often cause loss of clarity. This is a real advantage in reverberant rooms and installations where coverage must remain clear even at high volume levels.

Directivity, Crossover, and Construction: What Makes the Difference

Constant Directivity: More Uniform Listening Experience

A constant directivity horn aims to maintain similar dispersion over a wide frequency range. Practically, this results in better coherence between on-axis and off-axis responses, facilitating a balanced sound in the covered area. In speaker configurations, this consistency also simplifies overall optimization (alignment, equalization, crossover tuning), as the response varies less abruptly with listening angle.

Coverage 80 deg x 60 deg: Control and Precision

The 80 deg (H) x 60 deg (V) coverage offers a widely used compromise in sound reinforcement: wide enough to effectively cover an audience, while sufficiently directional to retain impact and precision. This format is relevant when you want to avoid unnecessarily "spraying" reflective surfaces and when seeking a stable sound image, especially for vocals.

Crossover Frequency: A Working Baseline

The ME90 specifies a cut-off frequency at 0.9 kHz. This value serves as a design reference: it helps locate the frequency range where the horn begins to effectively control directivity. For successful integration, the pairing with the driver and crossover must be considered as a whole (driver, horn, filter/processing, slope, level). Careful tuning will allow you to exploit projection and intelligibility potential while preserving the driver's power handling.

Aluminum: Rigidity and Stability Under Intensive Use

The aluminum material provides a robust and stable structure, appreciated in sound reinforcement environments where mechanical stresses (transport, vibrations, assembly/disassembly) are frequent. It also contributes to good dimensional stability and durable finishing, an important point when aiming for a clean integration in a speaker, whether in fixed installations or mobile use.
