OSD ACE870 8" Trimless 15-Degree Angled LCR In-Ceiling Speaker (Single)
The OSD Audio ACE870 8-Inch Angled LCR Trimless In-Ceiling Speaker (Single) delivers high-output home theater dynamics, room-filling 35Hz bass authority, and precise directional soundstage imaging without speakers on the wall. Built with an 8-inch carbon fiber composite cone woofer fixed at a 15-degree angle with butyl rubber surround and a 1-inch pivoting aluminum dome tweeter, the ACE870 aims sound toward the listening area across 35Hz to 20kHz with 175W power handling and 88dB sensitivity. Featuring a front-mounted bass and treble contour switch, gold-plated 5-way binding posts, and four easy-to-lock dog-ear brackets, this angled speaker is engineered for front LCR channels, surround channels, or immersive Dolby Atmos overhead height effects.
If you want to know how an 8-inch angled carbon fiber woofer focuses high-energy cinema sound directly at your seating position, how an aimable 1-inch aluminum dome tweeter fine-tunes high-frequency detail, or how front-mounted contour switches optimize room acoustics, the OSD ACE870 delivers unrivaled architectural power. Home cinema enthusiasts and custom installers searching for 175W power handling, 9.87-inch cutout dimensions, and a 10-year warranty will appreciate the massive dynamic headroom of the ACE870.

Angled for Focused Theater Sound
Aims sound at the seating area and allows ideal placement closer to walls, preserving the critical acoustic imaging and soundstaging that down-firing ceiling speakers lose. The 15-degree angled geometry is ideal for front LCR channels, surround sound, and immersive overhead formats like Dolby Atmos.
Impressive 35Hz Bass with Carbon Fiber Woofer
An 8-inch carbon fiber composite woofer and a heavy-duty, efficient magnet structure focus energy in the voice coil gap to deliver strong, articulate bass down to 35Hz with crisp, uncolored midrange. A butyl rubber surround provides greater excursion and long-term durability.
Pivoting Aluminum Tweeter & Front Contour Switch
Aim the 1-inch aluminum dome tweeter toward your primary seat, then use the front-mounted contour switch to tailor bass and treble response to room acoustics—all directly from the front baffle after installation.
Trimless Magnetic Grille & 4 Dog-Ear Brackets
The spray-paintable magnetic micro-flange grille sits flush against ceiling drywall for a clean architectural finish. Four easy-to-lock dog-ear brackets secure the speaker firmly into a 9.87-inch cutout, backed by gold-plated 5-way binding posts.
