Features & Specifications

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 6.5” Carbon Fiber Woofer fixed at a 15° angle, a 1” Aluminum Dome Tweeter, and a 90W power handling. You can even use them for Dolby Atmos front, rear and side surrounds in a 5.1 or 7.2 ystem. 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 15° 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. While wiring requirements will depend on your local building codes, OSD Audio offers CL3/FT4 cable that is UL (fire) rated for all residential and most commercial in-wall and in-ceiling applications. (The exception is you can’t run this cable in heating or cooling ducts in commercial applications.) This 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 in-wall.

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 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.

Other Product Info

Introducing LCR Angled in-ceiling speakers with revolutionary designs for imaging and staging that would be lost with regular, down-firing in-ceiling speakers. We accomplish this with our woofers set at a fixed 15° angle. The critical high and mid-range frequencies are then pointed toward the listener, not the floor. So, when your video tracks left to right, the sound tracks right along with the video. You can even use them for rear and side surrounds in a 5.1 or 7.1 system.

Tim
from Buckeye,Arizona asked:
December 4, 2018
I wish to do Dolby Atmos 7.1. I am looking at the IW550LCR for center and ACE870 for fronts and 4 ACE670 for surround and height. Will the center being located at listening level while the fronts at ceiling level be a problem? My ceilings are 10'. Would it be better to do 3 ACE 870 in the front?
1 Answer
Hi Tim: The ideal setup is to utilize three of the IW550LCR as your front stage if you can do so. The Angled In-Ceiling speaker originally was created for applications where the only the front stage option was going in-ceiling. The reality is the angled speaker not only works very well for front stage applications but provides an excellent choice for Surrounds and Effects. We push the ACE870 for front stage and the ACE670 for the Surround and Effects options. Either application will work for you, but I think the three IW550LCR would be our first choice. TL/ 5316

Andrew
from Atlanta, GA asked:
May 29, 2018
OSD states a 3 cubic foot box or larger is required when demoing this speaker. You state that a 1-1.5 cubic foot box should suffice for installation. I’m confused as to the size of box I should build or whether I should forgo the box altogether and simply protect the speaker with some denim insulation. What would be optimal? Any thoughts would be appreciated.
1 Answer
Hi Andrew: 1.5 would be fine for your application and when you add fiberfill to tune the box the more fiber you add the more the low frequencies are absorbed making the speaker think it is working in a larger box. The 3.0 cubic box they referred to was if you were building a box to demo or listen to the speaker before you mount the speaker in the Ceiling/wall (not sure why you would do that). Note the woofers in most In-Ceiling and in-wall speakers feature an infinite baffle so it adjusts to whatever size enclosure it is placed in (Just like a car speaker using the trunk). In most in-ceilings, it is in a ceiling joist cavity. In this case, if you are putting a right and left speaker in the same joist cavity you would want to isolate the two. Also, not everyone has an open wall or ceiling with access to build an enclosure. Sorry for the confusion... TL/5013

When will these speakers be back in stock?
1 Answer
Hi Timothy: It will be a while before the ACE670 and ACE870 will be back in stock, that is the bad news the good news we have something similar available to you. Checkout osdaudio.com, and look for the Black Series specifically the R63A with the Metal dome tweeter or the R62A with the soft dome. There is also a 8" version as well (like the ACE870) the R83A or soft dome R82A. You will need to contact customer service directly at OSD for a quote. The Black series is a full line of architectural speakers featuring a good, better and the best option. 1-562-697-2600 (sales). TL/4796

PaulH
from Phoenix, Arizona asked:
November 17, 2017
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?
1 Answer
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 tim@osdaudio.com. 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

Jeff
from Richmond, Virginia asked:
November 13, 2017
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.
1 Answer
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

from texas asked:
March 22, 2017
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.
1 Answer
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

May 26, 2016
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?
1 Answer
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

So, are we still talking about a long time to get these back in stock? I asked in another area about the best speakers for my 7.2 setup and was pointed to these although I am not sure why as it seems they are basically unavailable. If you have any idea of when they might be coming please let us know. I need to either wait or go elsewhere. I love OSD stuff but can't wait forever.
1 Answer
HI Tony: We do have an alternative, our Premium OSD Black Series. The Point 3 series R83A and R63A have the Ceramic Coated Aluminum metal dome tweeter with Carbon Fiber Woofer and the Point 2 Series R82A and R62A features Parachute Silk Soft Dome Tweeter with Graphite Mineral filled Woofer cone. Typically we recommended the ACE870 (8.0" 2 way angled speaker) for the LCR Left, Center and Right front stage speakers and the ACE670 (6.5" 2 way angled speaker) for the surround/effects speakers. Check our OSD Audio Premium site. There is no pricing on our site but we can provide a quote and help with the setup. my contact is tim@osdaudio.com. Note: The ACE870 and ACE670 have been ordered and should be in stock hopefully no later than mid May 2018. TL/4851

Hello, I am looking for a speakers for a 5.1 surround sound system I will be installing within my home. The room is rectangle and roughly 25 x 15. I was thinking of the ACE670 6.5 or should i go with an 8 inch. Also looking for some back ground music speakers for my kitchen area which is open to a large room.
1 Answer
Hi Marion: Both the ACE670 and ACE870 are currently out of stock. We usually recommend the ACE870 for LCR, Left, Center and Right front stage and then using ACE670 for Surround Rear and Height/Effects speakers depending on whether you add for Dolby ATMOS or DTS:X. It does depends on your Receiver which I am assuming is at least a 7.1 (more than 5 years old) or 7.2. Checkout the OSDAudio.com Premium Audio web site and checkout the Black Series R83A/R63A or the more affordable R82A/R62A. These are in stock, but you must contact customer service to get a quote.

January 12, 2018
I am installing MK870 as the front right, center and left speakers in the ceiling. The ceiling is 12 feet high. How would these work as the rear speakers or should I go with the same speaker (MK870) as the rear speakers?
1 Answer
HI Ron: Typically we recommend using the Angled 8.0 Inch LCR speakers for the Right, Center and Left front stage speakers. Then we recommend using angled 6.5" for Surround and Effects speakers (ATMOS or DTS:X). I believe we are out of stock on the MK870 (which I believe are being discontinued) since most of the demand is for trim less versus the standard frame of the MK series. But we may also be out of the ACE670 and ACE870. So I will need you to contact Ed our internal sales manager to talk about a substitute for the Angled 6.5 inch ACE670. ed@audiogeargroup.com. TL/4744

Is there a maximum ceiling height that you recommend these being installed on? I've got high ceilings (12-ft) in my living room and I'm afraid they'll be too high. Also, should all of the insulation in the ceiling (cellulose) be kept away from the speakers after installation or can it be put back on top of the backside of the speakers without affecting the performance?
1 Answer
Hi Brandon, For 12ft ceilings, I would recommend going up to the ICE870 angled speakers. I would keep a space clear in the insulation above the speaker to be safe. Thanks. -BM 2179

February 9, 2013
I plan to use these for LCR .... for the rear surrounds ... should I use this and angle it towards the center sofa position, or the ICE650 and have it shoot straight down?
1 Answer
Hi Daniel, Great choice! We suggest the ICE650s if you are able to mount the speakers within two feet (in either direction) directly above your seating area. You can use the angled speakers if you have to mount the speakers farther back. Most customers will use three angled speakers in the front directing the sound toward the couch and a down firing pair for the rear surrounds, such as the ICE650 right above the seating area.

Great Dolby Atmos Speakers
I don't have much experience with in-ceiling or in-wall speakers but wanted to find a solid pair of speakers to use as Dolby Atmos top speakers. On the recommendation of the AVRant podcast, I found the Outdoor Speaker Depot and decided on the ACE670's. The ACE670 appears to be a well built, no nonsense speaker at a fair price. The carbon fiber cone and rubber surrounds should help the speaker to survive in my hot attic. The angled design allowed me to mount the speakers in front of my seating area and away from the surrounds to allow for some separation in my small living room. I built a 1.5 cu ft enclosure for each speaker and added fiber fill to the box as well. My only concern is that there doesn't seem to be a hard and fast rule as to how much fiber fill to use and I have no desire to return to the attic for experimentation. The ACE670's blend well with the rest of my speakers and work very well as Dolby Atmos top middles. I have no idea how demanding Atmos soundtracks are on speakers but the ACE670's should be up to the task.
ProsCarbon fiber cones. Butyl rubber surrounds. Angled design. Directional tweeters. Price!
ConsNone so far.

Best Bang for Your Buck
Bose, Infinity, Polk, Boston Acoustics, Klipsch, Outdoor Speaker Depot. "Which one of these things is not like the other?" Well, the last one, of course. What the last one has that the others do not is BEST value. Who would have ever thought OSD would be listed with these names? Not me, but I tell you what, I put OSD ahead of these when I recommend speakers from now on. This speaker is used for my center channel for my home audio system. It is powered by an Onkyo receiver~110 watts per channel. The overall sound output and quality of this speaker is fantastic! I also play them in all channel stereo mode. These speakers never sound harsh and just beg for more power and volume. They have very well constructed frames, impressive materials, and crossover units that made me raise my eye-brows in disbleif because of what I paid for them. It's true if I spent 5 times what I paid for them, I would say they are still worth the cost. Both lows and highs have a switch for -3, 0, or +3 db sound attenuation or enhancement. They have a very pleasant sound, highs sound crisp, clean and never harsh. Mids are smooth and warm. Lows are not earth shattering, but if they were in their own enclosure (mine are backed by insulation) it may be a different story. Mate them to a powered subwoofer to get the most from the overall sound. Overall they do not sound as loud as the ICE660 I also purchased from OSD, but they also do not sound as harsh at times at high volume levels as the ICE660's did. If you want high power handling and superior quality materials and flexibility get these speakers!
