The Bose SM10, Delta Q Array Loudspeaker provide 10 Deg nominal vertical coverage with included field-changeable waveguides offering choice of 70 Deg or 100 Deg horizontal coverage. Replace single waveguide panel to form horizontal asymmetrical patterns. The 2-way module requires external power amplifiers (2- channels) and DSP to provide full-range response from 59 – 18,000 Hz with peak array output up to 145 dB. DeltaQ technology is the next-generation array design that allows “Q” (directivity) to vary with each module in the array for more consistent coverage over wide frequency range, reduced array weight and cost, and outstanding vocal clarity. Arrays can cover large vertical angles with fewer boxes. Changeable Waveguides Includes both 70°and 100°waveguides to adjust horizontal coverage. Largest-in-class size provides superior coverage control and vocal clarity. Change single panel for asymmetrical patterns. Compact, Portable Enclosure Versatile design allows both fixed install and portable applications, from small clubs and houses of worship to the largest performing arts centers and AV productions. Tour-Sound Output Level 4x Bose Professional EMB2S compression drivers, improved with more HF output, and 2x 8-inch neodymium high-power woofers allow array output up to 145 dB SPL. Removable Side Rigging-Guard/Handles Provides rigging guard and hand holds for portable applications. Easily removed for permanent installs for reduced width and cleaner visual appearance. .iframe-container{ position: relative; width: 100%; padding-bottom: 56.25%; height: 0; } .iframe-container iframe{ position: absolute; top:0; left: 0; width: 100%; height: 100%; } Product Specifications: Frequency Response (-3 dB) 69 Hz - 16 kHz Frequency Range (-10 dB) 59 Hz - 18 kHz Nominal Coverage Pattern (H x V) 100° H x 10° V (includes waveguides for 70° H x 10° V) Long-Term Power Handling Low Frequency: 450 W (1800 W peak) High Frequency: 100 W (400 W peak) Nominal Impedance Low Frequency: 8 Ω High Frequency: 6 Ω Sensitivity (SPL / 1 W @ 1 m) Low Frequency: 94 dB high Frequency: 106 dB Maximum SPL @ 1 m Low Frequency: 121 dB High Frequency:126 dB Calculated Maximum SPL @ 1 m, peak Low Frequency: 127 dB High Frequency:132 dB Shipping Weight: 84 lbs Shipping Dimension (L, W, H): 40, 25, 20
