The ACE840TT, like its younger sibling the ACE640TT,offers excellent stereo sound and takes up half the space of a standard speaker pair, while still delivering smooth, 2-channel sound.Works great for whole house audio applications. These speakers were created specifically for an application where you have a right (+/-) and left (+/-) stereo signal coming into a room where you only have space for a single speaker. So you would connect one pair of conductors to one set of inputs (+/-) and the second pair of conductors to the second set of inputs.The ACE840TT produces more bass response and covers a larger range than the 6.5" version.
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.
What Is a Dual Voice Coil Ceiling Speaker?
A Dual Voice Coil (DVC) Ceiling Speaker uses a special voice coil cone design that allows both channels of a stereo system to drive one cone. Sounds complicated but it's not. Basically, a DVC speaker plays both right and left channels through one speaker cone. You get both channels but without the acoustic separation that happens with two speakers. There are places like bathrooms, closets or hallways that just canâ€™t accommodate multiple speakers, so a DVC speaker solves the problem and produces great sound.
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 hereâ€™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 youâ€™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 canâ€™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.

4 Questions asked
What's on your mind?
Eric • 12/17/2019, 2:17:43 PM What speaker wire is required for this speaker? 4 conductor or 2 conductor (2x) connected to amp?
Customer Service • 12/17/2019, 2:17:43 PMHi Eric: Either will work, the four conductor is a little easier since it is one wire with four internal conductors. Typically we recommend red; right side positive, black; right negative, White; left side positive, and green; left negative. 16 AWG will work fine (16/4) up to 80 feet. For runs longer than 80 feet we suggest 14 AWG (14/4). 16 gauge works better if you are connecting to an input for a speaker selector or volume control. Note, use either one of the input connections (since they are not labeled) on the ICE840TT, so use the red and black on one and the white and green on the other. Left and right are combined so not critical which input you pick for either. TL/5236
Mike C. • 12/17/2019, 2:17:43 PM Can you please explain â€?cutout dimensionâ€? means and how it relates to pre-construction brackets.
Customer Service • 12/17/2019, 2:17:43 PMHi Mike: The correct New Construction Bracket for the ICE800TT is the NCCB8. Here is how you determine the fit of a New Construction Bracket for a particular speaker. As an example, the cutout hole dimensions for the ICE800TT is 9.0" (as listed in the Specification). The actual outer dimension of the speaker is 10.25". This number tells me I have 1.25" available. The NCCB8 has an opening of 9.5" so I have a difference of .75," but you have to cut that in half to see what the overhang would be; so about. 375" all around. And they both are in stock. You had also asked about backing for this speaker especially if you are dealing with an exterior wall or any wall where there will some form of insulation. We do not have an affordable option for this speaker but would recommend a product from OEM Systems. Here is the link from a company that stocks this product ironically based in San Diego: https://www.homecontrols.com/OEM-Systems-Insu-Flate-Ceiling-Speaker-Protection-OEISF147. I hope that helps TL/5438
FRANK • 12/17/2019, 2:17:43 PM Would I notice a difference between this and the discontinued ICE840TT? I have 2 of the ICE840TT's and now I'm installing another home speaker and would like to keep things consistent. It looks to be the same size, just a little lower max wattage.
Customer Service • 12/17/2019, 2:17:43 PMHi Frank:The ACE series speakers feature a trim-less design versus a standard frame. The original ICE840TT was a big seller for us. The ACE840TT has also done well. There should be little to no drop-off. I might have recommended the ACE850 but we are out of this model.TL/5567
Stephan • 11/17/2021, 4:02:28 PM Can this speaker be used in a commercial acoustical suspended ceiling?
Customer Service • 11/19/2021, 12:36:02 PMHi Stephan: THe ACE840TT needs to add a 70V Transformer to use for a 70V commercial system in a acoustical suspended ceiling unless you are featuring an 8-ohm system. Note; some areas demand that commercial speakers feature a back-box. These are open backed. Check local regulations. TimL/11/19/21
