Biamp Systems COLS81 2-way, 8 x 2-inch, white, column loudspeaker with 1-inch tweeter (910-01589)

Deliver powerful, intelligible audio with the Desono COLS81 2-Way Column Loudspeaker, engineered for professional installations where controlled sound coverage and exceptional speech clarity are essential. Featuring a slim, discreet design, the COLS81 blends effortlessly into its surroundings while providing outstanding performance for houses of worship, auditoriums, conference facilities, hospitality venues, concourses, and other commercial indoor and outdoor environments. Equipped with eight 2-inch drivers in a 2-way column configuration, the COLS81 delivers clear, natural sound with a highly focused dispersion pattern. Its controlled directional coverage helps project audio precisely where it is needed while reducing unwanted reflections, resulting in improved speech intelligibility even in acoustically challenging or reverberant spaces. Whether reproducing spoken announcements or background music, the COLS81 ensures consistent, high-quality audio across the listening area.

Built for year-round reliability, the weather-resistant construction makes the COLS81 suitable for both indoor and outdoor applications, including patios, concourses, covered walkways, and other exposed commercial spaces where dependable performance is required. The integrated 4-position switchable transformer supports 70V/100V constant-voltage audio systems, with selectable power taps ranging from 3W to 30W. A low-impedance bypass is also included, providing greater flexibility when integrating the loudspeaker into a variety of professional sound systems. This makes the COLS81 an excellent choice for distributed background music (BGM) and voice reinforcement across larger commercial spaces.

To ensure seamless architectural integration, the enclosure can be painted any colour, allowing the loudspeaker to match its surroundings while maintaining its clean, unobtrusive appearance. Combining focused sound dispersion, outstanding speech intelligibility, flexible system compatibility, and durable weather-resistant construction, the Desono COLS81 is a reliable solution for commercial audio installations that demand both performance and aesthetics.
