OSD ACE8408" Trimless Thin Bezel High Definition 2-Way In-Ceiling Speaker Pair
If you subscribe to the belief that speakers should hear but not seen, then our ACE (Architectural Ceiling Element) series in-ceiling speakers are for you! Combining elegance, style, and superb audio performance, the ACE840 in-ceiling speaker has a discreet, modern design that interiors decorators love; however, these top quality in-ceiling speakers come through strong on audio performance. Power handling is rated at 100W, so the ACE840 will fill even large spaces with beautiful sound, while the 8' Fiber Glass Woofer and 1" Pivoting Titanium Dome do their part to enhance sound as well. Note the nearly invisible micro-flange grille (0.15") that gives the ACE speakers that sleek, clean appearance. These speakers are excellent for home theater and media rooms and even allow you to adjust the bass and treble to suit your personal tastes.

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.
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.

Connected a pair of these speakers to my receiver using a VMS300 volume controller. to hear a faint sound from the speakers the volume control needs to placed on the highest volume setting. When I turn up the receiver volume the receiver then shuts down after 10 seconds. What could be causing this issue
Customer Service • 12/17/2019, 2:17:43 PM
Hi Nik,
Check to see what the impedance switch on the back of the volume control is set to. If you're only running one pair off your receiver, it should be set to 1/2x. Technically you should be running a non-impedance matching volume control if for max power, but the VMS300 should still work just fine. How much power (in watts) is your receiver putting out into the volume control?

Which new construction bracket works for this one?

I want to drive these speakers from a I2000M intercom. The out put of a room station is around 2 watts. There will be 2 speakers in series. Is this reasonable?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Bill:
I am assuming you will be using a pair of these speakers and wire them in Series as recommended by Intrasonic Technology. They should work fine. The output signal is summed mono or full range Mono.
Good Luck
