Constructed from durable cast aluminium, the ME142 provides excellent structural rigidity and long-term reliability while maintaining the precise acoustic geometry necessary for consistent performance. Whether used in line arrays, installation systems, performance venues, houses of worship, theatres, or custom loudspeaker projects, the B&C ME142 offers the coverage control and acoustic precision required by modern professional audio applications.
Purpose-Built for Line Array Systems
The B&C ME142 has been specifically engineered as a line array optimized waveguide, making it an ideal solution for applications where multiple loudspeaker elements must operate together as a coherent system.
Line arrays require carefully controlled wavefront behaviour to ensure smooth summation between adjacent cabinets. Poorly controlled dispersion can result in comb filtering, inconsistent coverage, and tonal variations throughout the listening area.
The ME142 helps address these challenges through its optimized waveguide geometry, allowing sound energy to be distributed more predictably across the audience. This contributes to improved array performance, smoother coverage transitions, and greater overall system consistency.
For system designers and manufacturers developing modern line array solutions, the ME142 provides an effective foundation for achieving professional results.
Wide 120° Horizontal Coverage
One of the most significant features of the B&C ME142 is its exceptionally wide 120° horizontal coverage pattern.
Wide horizontal dispersion allows sound systems to cover larger audience areas while maintaining consistent frequency response and tonal balance.
