It uses a vertical array of eight 3.3-inch drivers to produce controlled vertical directivity that projects sound 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, auditoriums, and other reverberant rooms. A switchable transformer supports 70 V and 100 V distributed systems with a low-impedance bypass.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe COLW81 sits between the COLW41 and COLW101 in coverage, using an eight-driver column array to balance throw and footprint for medium-to-large rooms. The COLW series is voiced for both speech and music, so it handles spoken word, program audio, and worship music from a single loudspeaker while its column directivity keeps energy on the listeners rather than the room. The cabinet is sturdy extruded aluminum and weatherproof for indoor or outdoor use, supporting covered exterior areas as well as interior halls. A multi-tap switchable transformer allows 70 V or 100 V distributed operation, with a low-impedance bypass for direct amplifier use. For larger or smaller coverage areas, the range also includes the \u003ca href=\"https:\/\/creationnetworks.net\/products\/biamp-910-01591-colw101\"\u003eCOLW101\u003c\/a\u003e and \u003ca href=\"https:\/\/creationnetworks.net\/products\/biamp-910-01592-colw41\"\u003eCOLW41\u003c\/a\u003e.
