    The phrase we hear most often when customers describe our ACE600 trimless thin bezel in-ceiling speaker is, "what a bargain!" This trimless speaker pair really is a bargain when you consider the components that go into it. The ACE600 moves into the larger 6.5" woofer for excellent bass for home theater systems and a 3/4 " silk dome tweeter for crisp highs. The ACE600 and our entire ACE (Architectural Ceiling Element) series of in-ceiling speakers combine elegant, modern style with outstanding audio performance. The invisible trimless grill design gives the ACE speakers a clean and sleek appearance that seamlessly integrates into any design space. Adds less visual impact on your architectural audio installation.

    Why Go Trimless?
    It's really a matter of aesthetic preference. These flush mounted speakers are hardly noticeable; that is until they're playing. Our Architectural Ceiling Element (ACE) Trimless speakers do not include the 3/4-inch trim you typically see around in-wall and ceiling speakers. 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.

    How Does this Speaker Mount in the Ceiling?
    Customers often ask us if they need special installation mounting brackets on their OSD ceiling speakers. The answer is no and here’s why. All our in-ceiling speakers feature a dog leg (L-shaped) mounting system that is part of the frame. Before you install the speakers, remove the grille and you’ll see several the mounting screws near the front frame. These screws need to be loosened to activate the dog leg clamps. Use a screwdriver to loosen (turn to the left) these screws and the clamp will come loose. When the speaker is in position in the ceiling, tighten (turn to the right) the screw and the speaker will be secured to the ceiling.

    What Type of Speaker Wire and What Gauge?
    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. 

    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 the foam at 12 to 15 years.

    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 the wall or ceiling. Uninstalled in-wall/in-ceiling speakers will sound weak and tinny because without the proper enclosure (in this case your house wall) 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.

    Kathleen • 12/17/2019, 2:17:43 PM Can these speakers be painted? Are they easy to install? Our home is pre wired.

    Hi Kathleen, OSD Audio ceiling speakers come with dog-eared clasps that tighten down onto your ceiling by using a Philips tip screwdriver. These speakers are easy to install, and you can paint the frame and grilles to match your d�cor. We do recommend using fine spray paint to avoid clogging the holes of the grille. CL/MA 1637
    Jamie • 12/17/2019, 2:17:43 PM Do you have any ceiling speakers that are black? Thanks very much
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Jamie: Look at either the ACE600 or ACE800. All of our speakers have frames and grills that you can paint. And in the case of the Trim-less design the grill can be painted so all you see is the black grill. You have to make sure to remove the internal cloth on the inside of the grill (if it has one). The cloth was used to hide the color of the cone or baffle from showing through the grill. But both the ACE600 and ACE800 feature black Grills, Black Tweeter and black Baffle so all you see is the black grill. TL-2127

    Hello Hector, Yes, these are in-ceiling speakers that are recessed.
