About the Bose SM10 DeltaQ ShowMatch Array Loudspeaker - 100 Degree Horn
The Bose SM10 is a high-performance, two-way arrayable loudspeaker module designed as a core component of the ShowMatch DeltaQ line array system. It features a proprietary 100-degree horizontal coverage horn that is central to the DeltaQ array technology, allowing multiple cabinets to be stacked vertically with electronically steerable vertical coverage while maintaining a consistent 100-degree horizontal dispersion. This design enables sound engineers to precisely tailor the vertical coverage pattern to the audience area, optimizing sound pressure level (SPL) distribution and minimizing energy wasted on ceilings or empty spaces. The SM10 integrates a 10-inch low-frequency driver and a 1.4-inch exit compression driver on a precision waveguide, delivering high output with exceptional clarity and pattern control for live sound reinforcement in touring, installed sound, and large venue applications.
The cabinet is constructed from premium birch plywood with a durable, textured finish and features integrated rigging hardware that allows for quick, safe, and accurate array assembly. The DeltaQ array processing, typically managed by dedicated Bose control amplifiers (like the PowerMatch PM8500N) and software, uses complex filtering to achieve the steerable vertical directivity, allowing a single array of SM10 cabinets to cover both near and far fields effectively. This results in a more uniform audience experience with improved intelligibility and reduced feedback potential. The system is designed for high-power handling and low distortion, making it suitable for the demanding requirements of modern music and speech reinforcement.
As a key element of a scalable array system, the Bose SM10 with its 100-degree horn provides the foundation for creating tailored, high-impact sound systems for concerts, performing arts centers, stadiums, and houses of worship. Its combination of advanced directivity control, robust construction, and sonic transparency makes it a powerful tool for audio professionals seeking to deliver consistent, high-fidelity sound across complex listening environments.
