Kevlar® is the best component for woofers. It responds note for note without coloration and has big cranking power so you can dial up your system for higher listening levels.

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. 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.

Jerry • 12/17/2019, 2:17:43 PM Is this speaker suitable for exterior use on a covered porch
Customer Service • 12/17/2019, 2:17:43 PM
Jerry, This speaker is not sealed for the elements. The ICE800wrs is though. It is great in bathrooms or covered patios. Cl
Jim • 12/17/2019, 2:17:43 PM I am trying to decide between these speakers and some ace840. These seem higher quality, but the others are larger... I was going to get 2 sets one for a larger master bedroom 350sq ft ceilings, and another set for a covered deck... what are your recommendations?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Jim, The ACE650MKs are the top of the line and feature Kevlar cones, butyl rubber surrounds and an elaborate crossover network. Typically in a bedroom, you want to be able to listen while in bed so a pair of the ACE650 placed 12 feet apart with a speaker mounted above the bed on either side would be ideal, making sure to pivot the tweeter facing down towards the pillows. The ICE840 may be a better choice for outside where you will need a broader sound field. Both speakers are an excellent choice. I hope that helps Tim L
Marius Jul Pettersen • 12/17/2019, 2:17:43 PM Hi! How many speakers do you recomend for a 270sq ft livingroom? Does it provide enough bass or do I need an additional subwoofer?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Marius, You would need a minimum of two pair or four each. I would recommend looking at our new MK690TT speakers. These are dual application speakers that feature Dual Voice Coils and Dual Tweeters. They have a unique 4/8 ohm stereo/mono switch that allows you to connect the speakers as a stereo pair (connecting just one of the voice coils and setting the switch to 4 ohms). Assuming you have room (15 x 18 feet), I would mount each speaker 5-foot from the short wall and 4-foot from the long wall. The beauty of these speakers is the dual tweeters that dramatically increase the dispersion pattern of the high frequencies. I would start there then determine if you want to add a dedicated powered subwoofer like our PS88. Good luck! TL/MA
Stelios • 12/17/2019, 2:17:43 PM I want to install these speakers in my living room as surround speakers ( the 2 back/side speakers in a 5.1 setup) The living room is about 20 feet x 17 feet. Should I step up to the bigger size or will these be just fine?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Stelios, Although the 8" are not much more and you are right on the cusp as far as dimensions to step up -the larger size, the ACE650MK's will give you enough sound for your home theater. However, if you are considering the 8-inch speaker, it wouldn't hurt to go bigger. ACE850MK would be the part number. CL 1376
Matt • 12/17/2019, 2:17:43 PM Would you offer a discount if I ordered 5 pairs of theses?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Matt, Like all our wall and ceiling speakers, the ACE650 is already discounted so we can't negotiate a better price on 5 pairs. If you were to shop around, you would find the high quality materials used to make these speakers make them an excellent value. CL/MA 1541
