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.
Step-up Features!
For a retrofit installation, no construction bracket is needed.
Step-up Features!
- Silk dome tweeter for superb high frequencies
- Mica-filled polypropylene cone and butyl rubber surround
- Super discreet! Match your recessed lighting.
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.

I am wiring two sets of these speakers in parallel. I have 14 gauge speaker wire and the terminals cannot take two of these (at least it doesn't seem to be the case). Do you have any recommendations or tips as the best approach to connect two wires to each terminal?
Customer Service • 04/14/2020, 7:39:19 PM
Hi Tony:
If you can not home run both sets of wires back to the amplifier and the two 14 gauge speaker wires will not fit together in the Input terminal. Then you will need to add a single small two-conductor jumper cable and terminate three positive conductors(one from the amplifier, one from the first speaker and the third, the wire going to the second ACE-840) with a Yellow Wire nut. Do the same with the Black Negative conductor as well. You will need four wire nuts in total, Left and Right +/-. I will send a diagram to your email as well.

How would these speakers work with your breathe audio system? What other 8" trim less speaker would you recommend ?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Steveu:
These 8 inch speakers work very well with the Breathe Audio system. We have two other options for trimless 8", one being the more affordable ACE800 or the more expensive ACE850MK (our best). In the more convential frame speaker check out the ACE840TT,Dual Voice Coil, Dual Tweeter and dual application speaker. It features a 8/16 ohm switch which allows you to use it as a single summed mono stereo speaker in the 16 ohm position (ideal for bathrooms or hallways where you only have single choice for locations). The second option is to install a pair of these speakers where you connect one of the voice coils on each speaker and set the switch to 8 ohm. The dual tweeters in both applications give you broader distribution of the high frequencies.
The bottom line the Breathe Audio features plenty of power to drive any of our eight inch speakers. An an eight inch speaker usually offers more bass than a 6.5 inch speaker in the same series.

Hi,
I'm interessted in 2 or 3 pairs o this speaker and was wondering if you could give me a bettet price? Also, I've read on some swedish forums that you have arranged UPS shipping which is somewhat cheaper. Is his somehing you still can provide?
I think your USPS shipping estimates is somewhat off because if I use the calculate button its cheaper shipping (per pair) when you to just buy two pairs instead of three?

I installed and connected this speaker to my receiver using a VMS300 volume control. First I need to place the volume control in the max position to get any sound and the sounds is very faint. Then when I turn the volume up on the my receiver the receiver shuts down after about 10 seconds. I have checked all the wiring all looks to be good and snug. What could be the issue causing this.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Nik,
How many of the ACE840 speakers are you actually running off the one VMS300 volume control? Since they are sold in pairs, I'm assuming you are running 2 speakers off the volume control. What type of amp/receiver are you running to the volume control?
