Bose Professional ShowMatch SM20 DeltaQ Array Loudspeaker

The Bose Professional ShowMatch SM20 is a DeltaQ two-way array module designed for professional sound reinforcement systems where controlled vertical dispersion, high acoustic output, and scalable array configuration are required. The module uses two 8-inch low-frequency drivers and four EMB2S extended-high-frequency compression drivers. Its nominal 20° vertical coverage vertical coverage is designed for array applications where installers need to shape the acoustic field according to venue geometry and audience position. Field-changeable waveguides provide flexible horizontal coverage, with the 100° horizontal maximum configuration depending on model and waveguide selection. Replacing waveguide panels can create different coverage patterns and support horizontal asymmetry when required by the venue. The two-way design requires external amplification and DSP, allowing system designers to manage crossover, equalization, protection, and array processing within the larger sound system. Integrated rigging provisions support modular arrays, while the rugged enclosure and removable side guards are suited to touring and fixed professional installations. The platform is intended to provide predictable performance and straightforward integration when matched with compatible system components. Correct installation, loudspeaker matching, and system configuration help maintain the intended acoustic performance across the coverage area. Its practical combination of connectivity, processing, and installation features supports consistent operation in appropriately designed commercial sound systems.
