Features

2-Way Driver Configuration: The Architectural Ceiling Element (ACE) Series ACE870 in-ceiling speaker from OSD Audio employs a 2-way driver design featuring a 1" titanium hard-dome tweeter and a 8" fiber cone woofer with butyl rubber surround for crisp, detailed mid and high frequencies, as well as impressive deep bass.

Angled Design: The ACE870 in-ceiling loudspeaker incorporates 15-degree angled baffle for the mid/bass woofer, plus a pivoting mechanism for the high frequency tweeter for application & placement flexibility. Due to its angled design, OSD Audio ACE870 can be utilized as a Front, Center, or Rear channel speaker in a home theater setup. The angled design allows the ideal placement in the ceiling closer to the wall just above the monitor. This creates a more realistic sound image when compared to normal in-ceiling speakers that are mounted closer to directly above the viewing area. Standard in-ceiling speakers are generally placed at least 3' from the wall to avoid reflective sound, while the angled ACE870 speaker can be placed within a 1' of the wall.

Tweeter Level: You can adjust the output level of the tweeter to -3dB, 0dB, or +3dB. The tweeter level control is located on the front baffle behind the detachable grille. Highly reflective "live" rooms benefit from a -3dB reduction, while fabric-heavy "dead" rooms will sound better with tweeter boosted +3dB.

Spring Post Terminals: The OSD Audio ACE870 in-ceiling speaker is outfitted with a set of spring post terminals that accept bare wire (up to 12AWG), pin-connectors, and banana plugs (single only).

• For wire lengths of less than 50', use at least 16-gauge in-wall rated speaker wire (CL3/FT4).
• For wire lengths between 50' and 100', use at least 14-gauge in-wall rated speaker wire CL3/FT4).
• For wire lengths of greater than 100', use at least 12-gauge in-wall rated speaker wire (CL3/FT4).

Mounting Options: The OSD Audio ACE870 features a "dog leg" (L-shaped) mounting system that is part of the frame to secure the speaker in the ceiling. The speaker requires a round cutout that measures 9.694" (diameter) x 5.435" (depth). Its outer frame measures 12.0" (diameter) x 0.22" (depth). The "dog leg" (L-shaped) mounting system accommodates a 0.25" to 1.25" thick ceiling. Make sure to leave at least 0.75" of open space (without obstruction) around the cutout above the ceiling, so the speaker's "dog leg" mount system will have room to engage fully.

Low-Profile Magnetic Grille: The low-profile magnetic grille is removable and can be painted to better match the color of your ceiling. The low-profile grille only protrudes 0.22" from the ceiling's surface.
