The black OCS1B Orbit Ceiling Speaker from Bogen is a 2-way, 6.5" coaxial speaker. It is suitable for various ceiling applications as it can be installed on hard surfaced ceilings, or in suspended ceilings and new construction (with an optional TBCR bracket).

The speaker utilizes a spiderless driver and a one-piece metal alloy cone structure for clear articulation in both music and speech. It features a wide-dispersion coaxial driver, which has a coverage of 140° and a computer-matched venting system for full bass response. The speaker affords the user flexibility as it can be used at 16-ohms, or with 70V or 100V systems and power input selection is chosen by a front-mounted rotary switch located under the removable grille.
