Audiophiles Love Kevlar® Woofers
Kevlar® is a super strong material known for its ability to produce powerful but very smooth bass tones. Kevlar® woofer cones retain their shape even at very high energy levels, which means you can crank up the volume and experience spine-tingling sound without distortion or coloration.
Why Go Trimless?
It's really a matter of aesthetic preference. Our Architectural Ceiling Element (ACE) Trimless speakers do not include the the 3/4-inch trim you typically see around in-wall and ceiling speakers. This gives the speakers a much stealthier appearance. 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.
Pivoting Titanium Dome Tweeter
The job of the tweeter is to deliver the higher frequencies of music and soundtracks. The tweeter is also adjustable, meaning it can be aimed toward the listening area. This can make a big difference in sound quality especially for dialog and higher frequencies.
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.

“I was extremely worried about this purchase because I never buy speakers prior to listening to them. The price appeared to good to be true but I gave then a shot any way base on hear say. I received them,inspected them, installed them and wow!!! I love them... there incredible.”

“I bought these speakers having previous experience with OSD through a pair of outdoor rock speakers I purchased from them. OSD has been great with fixing any problems I have had and are by far one of the best companies I have dealt with. I bought these speakers as I am slowly putting in a whole house audio system (room by room). I put these speakers in knowing how great the rock speakers sound but I was absolutely blown away at how great the ACE850MK speakers sound. The base, the clarity, the sound in general is unbelievable. You will not go wrong dealing with OSD and these speakers. OSD also has an enclosure for these speakers which I recently purchased and hope to have installed by Christmas. Based on what I have read these enclosures for the 8" speakers will protect the back side of the ceiling speakers and improve the sound quality even more.”

“The quality of the product and the sound it produces is
right up there with the name brand speakers that one would pay much
more for. I am using them in a 7.2 theater system and they are
awesome!”
