Lifetime Tech Support

With the ACE670 trimless in-ceiling LCR angled speakers, you'll get imaging and staging that would be lost with regular down-firing in-ceiling speakers. Features include a sturdy 6.5ā€ Carbon Fiber Woofer fixed at a 15Ā° angle, a 1ā€ aluminum dome tweeter, and a 90W power handling. You can even use them for Dolby AtmosĀ® front, rear and side surrounds in a 5.1 or 7.2 system. Contour switches also allow you to tailor the bass and rebel to your preference.

What Are the Benefits of an Angled In-Ceiling Speaker?
The angled speaker is a real problem solver because not every space is ideal for custom home theater sound applications. The angled in-ceiling speaker features a 15Ā° angle for the mid-bass driver plus a pivoting tweeter for placement flexibility. This speaker can be part of three piece set to handle the front stage of the surround system when both on-wall and in-wall are not a favorable option. The angled design allows the ideal placement in-ceiling closer to the wall just above the monitor. This creates a more realistic sound image when compared to normal in-ceiling speakers that are mounted directly above the viewing area. Standard in-ceiling speakers are generally placed at least three feet from the wall to avoid reflective sound. The angle speaker can be placed within a foot of the wall.

The Trimless Design is a Nice Touch
The Architectural Ceiling Element (ACE) trimless thin bezel in-ceiling and in-wall speakers are a great choice for new construction or retrofit. These flush mounted speakers are hardly noticeable; that is until they're playing. 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 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 foam at 12 to 15 years.

Should I Purchase Special Cable for In-ceiling Speaker?
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. 

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-wall or in-ceiling. Uninstalled in-wall/in-ceiling speakers will sound weak and "tinny" without the proper enclosure (in this case your home walls) the speaker canā€™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.

What's on your mind?

JR • 12/17/2019, 2:17:43 PM Can the ACE670 be used of Dolby Atmos even though it does not specifically state that it's Dolby Atmos Ready? Would it be best to use one of those listed as Atmos Ready?
Customer Service • 12/17/2019, 2:17:43 PM
HI JR: This speaker is an excellent choice for your application. They are brand new in our catalog and we have not listed them yet as Dolby ATMOS. They exceed the current DOLBY ATMOS specs and with their angled design (15 degree with additional 5 degree for the pivoting tweeter) you will have more options for speaker placement. We now are recommend the ACE-870 for front Stage LCR and the ACE-670 for Effects (DOLBY ATMOS & DTS:X) and Surround In-ceiling Speakers. Great Choice TL/3899
Brian • 12/17/2019, 2:17:43 PM What is recommended enclosure volume and amount of polyfill for said enclosure? I am installing in-ceiling w attic access and a speaker box is a must.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Brian: Probably one to one and half cubic foot will work and then you can experiment in how much fiber fill you will need. The fiber fill makes the box appear bigger depending on how much you use. These woofers are infinite baffle so they can work in a broad range of enclosures. The box will definitely add to the speakers performance. Great choice for LCR, Surround or Effects (ATMOS or DTS:X) speaker. TL/4263
Jeff • 12/17/2019, 2:17:43 PM I am setting up my home theater in a ATMOS 5.1.2 configuration. I have Polk RT Front Right, front left and center channel. My AVR is an Denon AVR-X2400H. Would the ACE670 speakers work well for the ATMOS and rear surround? The room is open in the back so I need to place these speakers in the ceiling. I am concerned with using this as surrounds since the Dolby recommendation is to be at ear level. Would I angle all the speakers toward the MLP? Thanks for your insight.
Customer Service • 12/17/2019, 2:17:43 PM
HI Jeff: These ACE670 Angled LCR, Surround and Effects speakers are the perfect speaker for your application. Because of the 15 degree angle and extra 5% swivel of the tweeter it gives you flexibility in where you need to mount them. What Dolby is looking for is to have the Tweeter of each speaker aiming directly at the optimum Viewing/listening area. So both the speakers for ATMOS which will be mounted between you and the front speakers and the Surround speakers which will be behind your seating area can be placed in such a way so that Tweeter is aiming at that optimum site. It is the best choice for an application calling for ceiling speakers. A great selection. TL/4645
PaulH • 12/17/2019, 2:17:43 PM I will be installing the ACE870s as LCR in the ceiling above my TV. Can I use the ACE 670s at the rear speakers installed in the side wall of the room for a 7.1 system? The room is rather small 12 foot between the two side walls. Or would you recommend some other models?
Customer Service • 12/17/2019, 2:17:43 PM
HI Paul: The ACE670 would be perfect for your application. I would recommend putting the three ACE870 in the ceiling above the TV angled down towards the viewing area and then a pair of the ACE670 in the wall that extends from the overhang. Those would be the front ATMOS effects speakers. The second pair I would put in the back wall aiming down (not sure you have access to that wall. These would be the Surround speakers. Depending on your receiver this would be a 5.1.2 system. I will send you your images with locations I am talking about. Look for an email from Note, we also have a Square grill kit option for the ACE670 that might look better on the wall as well. I will send info on that. Good luck... TL/4654
Westy • 12/17/2019, 2:17:43 PM are the grills held on by magnet?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Westy: Checkout the picture of the backside of the ACE670 and you will see 7 of the 10 small Neodymium Magnets mounted into the frame. These do a great job holding the grill in place. TL/4692
