Biamp 910-01591 COLW101

Product Overview

The Biamp Desono COLW101 is a two-way, full-range column loudspeaker built for clear speech and music in acoustically challenging commercial spaces. As the largest model in the COLW column range, it uses a vertical array of ten 3.3-inch drivers to produce tight vertical directivity that projects sound to the audience while reducing reflections off floors and ceilings. Its extruded-aluminum, weatherproof cabinet suits both indoor and outdoor installation, making it a common choice for houses of worship, auditoriums, and other reverberant rooms. A switchable transformer supports 70 V and 100 V distributed systems with a low-impedance bypass.

Product Description

The COLW101 delivers even coverage and high intelligibility in rooms where reverberation would otherwise blur speech, using the controlled vertical directivity of a ten-driver column array to keep energy on the listeners rather than the room. The COLW series is voiced for both speech and music, so the same loudspeaker handles spoken word, program audio, and worship music in a single install. The cabinet is made of sturdy extruded aluminum and is weatherproof for indoor or outdoor use, which supports covered exterior areas as well as interior halls. A multi-tap switchable transformer allows the loudspeaker to run on 70 V or 100 V distributed lines, with a low-impedance bypass for direct amplifier operation. For smaller coverage areas, the COLW range also includes the COLW81 and COLW41, while the speech-optimized COLS models are available for paging and voice-only systems.
