Orbit Ceiling Speaker (OCS1) is the ideal choice for various types of ceiling environments. OCS1 features NEAR's MLS and MDT technologies, which improve sound quality and increase operating reliability. The low-distortion speaker design, featuring NEAR's spiderless driver and one-piece metal-alloy cone structure, delivers superb articulation and the highest intelligibility for both music and speech. The speaker can be easily installed on hard surfaced ceilings, or in suspended ceilings and new construction (with the optional TBCR bracket).
