Bose Professional ShowMatch SM10 DeltaQ Array Loudspeaker

The Bose Professional ShowMatch SM10 is a full-range DeltaQ array loudspeaker module engineered for high-output sound reinforcement in large and acoustically demanding venues. It provides 10° nominal vertical coverage and includes field-changeable waveguides that allow system designers to select 70° or 100° horizontal coverage for precise audience targeting.

This two-way array module requires external power amplification and DSP processing to deliver full-range performance from 59 Hz to 18,000 Hz. Bose Professional DeltaQ technology enables variable directivity across the array, delivering consistent coverage, reduced array size, and exceptional vocal intelligibility across wide seating areas.

The SM10 features a compact, tour-ready enclosure with integrated quick-pin rigging for fast deployment in portable or permanent installations. Removable side rigging guards double as handles for transport and can be removed for a cleaner visual profile in fixed installations.
