Lifetime Tech Support

With the ACE670 trimless in-ceiling LCR angled speakers, you'll get imaging and staging that would be lost with regular down-firing in-ceiling speakers. Features include a sturdy 6.5” Carbon Fiber Woofer fixed at a 15° angle, a 1” aluminum dome tweeter, and a 90W power handling. You can even use them for Dolby Atmos® front, rear and side surrounds in a 5.1 or 7.2 system. Contour switches also allow you to tailor the bass and rebel to your preference.

What Are the Benefits of an Angled In-Ceiling Speaker?
The angled speaker is a real problem solver because not every space is ideal for custom home theater sound applications. The angled in-ceiling speaker features a 15° angle for the mid-bass driver plus a pivoting tweeter for placement flexibility. This speaker can be part of three piece set to handle the front stage of the surround system when both on-wall and in-wall are not a favorable option. The angled design allows the ideal placement in-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 directly above the viewing area. Standard in-ceiling speakers are generally placed at least three feet from the wall to avoid reflective sound. The angle speaker can be placed within a foot of the wall.

The Trimless Design is a Nice Touch
The Architectural Ceiling Element (ACE) trimless thin bezel in-ceiling and in-wall speakers are a great choice for new construction or retrofit. These flush mounted speakers are hardly noticeable; that is until they're playing. The micro flange grilles are attached by extremely powerful magnets that stay put for quick and easy installation. Adds less visual impact on your architectural audio installation.

What Is Butyl Rubber Surround?
With almost double the shelf life of foam, butyl rubber has been the choice of speaker designers looking to optimize the sound based upon materials that go together. The surround is just one of the integral parts of the speaker's motor structure. Butyl rubber gives the speaker more excursion capability featuring a deeper bass with a wider frequency response, and its shelf life is closer to 25 years compared to foam at 12 to 15 years.

Should I Purchase Special Cable for In-ceiling Speaker?
Wiring is not included with in-ceiling speakers so you will have to purchase some. We recommend our OSD Audio CL3/FT4 cable that is UL (fire) rated for in-wall and outdoor speaker installs. This type of cable includes a heavy-duty outer jacket approved for in-wall/in-ceiling installation. The high-quality plastic jacket is also very flexible so it's easy to run the wires inside the wall. As for the gauge, for runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, we suggest 14-gauge wire. 

Testing the Sound Quality of In-ceiling Speakers
Many customers like to test the sound quality of their new OSD Audio in-ceiling speakers before they install them. Keep in mind, however, that these flush-mount speakers are designed to be used in-wall or in-ceiling. Uninstalled in-wall/in-ceiling speakers will sound weak and "tinny" without the proper enclosure (in this case your home walls) the speaker can’t produce the sound pressure level it needs. If you want to try them out, we recommend mounting the in-ceiling speakers into a box of about 3 cubic ft. or larger; or simply mount them in the ceiling and then listen. This will give you an accurate measure of the sound quality.

For a retrofit installation, no construction bracket is needed.
