B&C Speakers ME 45

A B&C Horn Designed for Sound Reinforcement and Speaker Integration

The B&C ME45 is a 1" driver horn designed to be integrated into sound reinforcement speakers, stage monitors, or DIY systems focused on performance. Its compact size and carefully considered dimensions facilitate the design of a clean front face while maintaining useful directivity to maintain the sound coverage of a system. With a specified cut-off frequency of 1.0kHz, it positions itself as a relevant solution for building an effective high-frequency section, consistent with common two-way configurations.

Who Is It For and What Are Its Uses?

This horn targets integrators, technicians, speaker manufacturers, and DIY enthusiasts seeking controlled projection and solid intelligibility in the upper frequency range. The 90deg x 40deg dispersion is particularly suitable for applications where you want to open the coverage horizontally while limiting vertical dispersion to reduce reflections (ceiling/floor) and improve vocal clarity. It is a coherent choice for a front-of-house speaker, a directional sound system, or monitoring when you want to avoid unnecessarily spilling sound into the environment.

Directivity, Profile, and Design: What the ME45 Offers

Exponential Profile: Projection and Presence

The ME45 features an exponential profile, appreciated for its direct character and ability to project efficiently. In a well-tuned configuration, this type of horn contributes to presence and attack, especially on vocals, guitars, brass, or any source requiring clear definition in the upper midrange and treble.

90deg x 40deg Coverage: Useful and Practical Dispersion

The 90deg horizontal coverage provides a good listening area width, while the 40deg vertical coverage helps keep energy where it is needed. This directivity also facilitates optimizing placement (height, tilt) and equalization work in real situations, delivering a more consistent response within the covered zone.

1" (25mm) Throat and Aluminum Construction

Thanks to its 1" (25mm) throat, the ME45 is compatible with commonly used 1" compression drivers. Its aluminum construction provides rigidity and mechanical stability, an asset for durable speaker mounting and limiting unwanted vibrations. Its compact size also allows easy integration without adding bulk to the design.
