    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.

    What's on your mind?

    Daniel • 12/17/2019, 2:17:43 PM I plan to use these for LCR .... for the rear surrounds ... should I use this and angle it towards the center sofa position, or the ICE650 and have it shoot straight down?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Daniel, Great choice! We suggest the ICE650s if you are able to mount the speakers within two feet (in either direction) directly above your seating area. You can use the angled speakers if you have to mount the speakers farther back. Most customers will use three angled speakers in the front directing the sound toward the couch and a down firing pair for the rear surrounds, such as the ICE650 right above the seating area.

    Cory • 12/17/2019, 2:17:43 PM Do the ICE670 speakers have the same cut-out template dimension as the ICE650 type speakers?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Cory, The ICE650 and ICE670 ceiling speakers have the same cutout: 8 1/4" CL/MA 1771
    Brandon • 12/17/2019, 2:17:43 PM Is there a maximum ceiling height that you recommend these being installed on? I've got high ceilings (12-ft) in my living room and I'm afraid they'll be too high. Also, should all of the insulation in the ceiling (cellulose) be kept away from the speakers after installation or can it be put back on top of the backside of the speakers without affecting the performance?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Brandon, For 12ft ceilings, I would recommend going up to the ICE870 angled speakers. I would keep a space clear in the insulation above the speaker to be safe. Thanks. -BM 2179
    Rob • 12/17/2019, 2:17:43 PM When building a 5.1or 7.1 in a 9ft ceiling which speaker is better, the ICE670 or MK670? Both have good features but I am unsure which to purchase. I would like ultimate performance for watching movies and sports. Thanks.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Rob, The MK670 is a higher-definition speaker and is on special right now. Thanks!
    Antrapment • 12/17/2019, 2:17:43 PM I am the process of putting together a 7.1 home theater system in my basement, the room size is L 20'xW 12'x H 6.5'. Which if the speaker would best suit for rear surround, the ICE670 or the MK670
    Customer Service • 12/17/2019, 2:17:43 PM
    Hello, Both are similar speakers in that they are 6.5" angled ceiling speakers intended for surround sound. The MK670 is the better of the two.
