Biamp 910-01587 COLS101

Product Overview

The Biamp Desono COLS101 is a column loudspeaker whose acoustic response is tailored specifically for speech, built for high intelligibility in reverberant commercial spaces. As the largest model in the COLS range, it uses a vertical array of ten drivers to produce tight vertical directivity that projects voice to the audience while reducing floor and ceiling reflections. Its extruded-aluminum, weatherproof cabinet suits both indoor and outdoor installation, making it a strong fit for houses of worship, transport hubs, and large multi-purpose rooms. A switchable transformer supports 70 V and 100 V distributed systems with a low-impedance bypass.

Product Description

The COLS101 is designed for paging and voice systems where clarity in a hard, reverberant room is the priority. Its ten-driver column produces controlled vertical directivity that keeps speech energy on listeners and off reflective surfaces, which is what makes column loudspeakers effective in churches, railway stations, and sports facilities. The COLS series is voiced for speech, distinguishing it from the speech-and-music COLW series, so it is the right choice for announcement and intelligibility-driven applications. The cabinet is sturdy extruded aluminum and weatherproof for indoor or outdoor use. A multi-tap switchable transformer allows 70 V or 100 V distributed operation, with a low-impedance bypass for direct amplifier use. For smaller coverage areas, the range also includes the COLS81 and COLS41; for speech and music, see the COLW101.
