The Orbit Ceiling Speaker (OCS1) is the ideal choice for various
types of ceiling environments.

The OCS1 features NEAR's MLS™ and MDT™ technologies
(see below), 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).

• Solid, one-piece cone structure eliminates the traditional

dust cap

• Extremely stable cone structure over long periods of time

• Fast transmission of sound through the diaphragm means

low energy storage

• Special hard anodizing process creates a ceramic surface for

increased stiffness

• Super-efficient thermal path for cooling the voice coil

(not paper or plastic)

• High rigidity and low mass of metal versus typical paper or

plastic cones

• Magnetic liquid (Ferrofluid) injected into magnet gap

• Elimination of the conventional cloth centering spider

• Constant lubrication of the gap prevents oxidation from

occurring

• Voice coil is most efficiently cooled by fluid path rather 

than air

• Lower distortion via stronger centering forces on voice coil

• Increased reliability, particularly in high power daily use 

systems
