Description
The OSD Audio ACE670 is a 6.5" angled LCR (left, center, right) trimless in-ceiling speaker that keeps the imaging and staging regular down-firing ceiling speakers lose. Its woofer is fixed at a 15-degree angle to aim sound toward the listening area, and a pivoting tweeter gives you even more control over placement.
- ANGLED FOR BETTER IMAGING: The 6.5" woofer is fixed at a 15-degree angle to aim sound at your seats, keeping imaging that down-firing ceiling speakers lose. Angled design suits overhead channels in immersive surround formats such as Dolby Atmos®.
- PIVOTING TWEETER: The 1" pivoting aluminum dome tweeter fine-tunes where the highs go, so dialog and effects stay clear from overhead. Carbon fiber composite woofer, 45Hz - 20kHz, 89 dB sensitivity, 90W handling.
- TUNE IT TO THE ROOM: A front-mounted contour switch lets you tailor the bass and treble to the room and your taste after the speaker is installed - no need to pull it back out of the ceiling.
- BUILT TO LAST: A butyl rubber surround gives deeper bass and wider frequency response, and lasts about twice as long as foam - roughly 25 years versus 12 to 15. Gold-plated 5-way binding posts keep connections secure.
- TRIMLESS AND EASY TO INSTALL: A spray-paintable magnetic micro-flange grill sits flush to the ceiling, and built-in dog-ear brackets lock in from the front. 8.12" cutout, 8.76" diameter, 4.5" depth. Sold as a single speaker.
- WARRANTY: Backed by OSD Audio's 10-year warranty.
Use the ACE670 for front left, center and right channels where wall speakers will not work, or as front, rear and side surrounds in a 5.1 or 7.2 home theater. Angled design suits overhead channels in immersive surround formats such as Dolby Atmos®. Because the sound is aimed, you can mount the speakers where the ceiling allows and still get focused sound at the seats.
Inside, a sturdy 6.5" carbon fiber composite woofer pairs with a 1" pivoting aluminum dome tweeter. Frequency response is 45Hz - 20kHz, sensitivity is 89 dB and power handling is rated at 90W. A front-mounted contour switch lets you tailor the bass and treble to the room after installation.
The woofer uses a butyl rubber surround, which gives deeper bass and a wider frequency response than foam and lasts about twice as long - roughly 25 years compared with 12 to 15. Gold-plated 5-way binding posts give a secure connection to any 8-ohm amplifier or AV receiver.
The trimless Architectural Ceiling Element (ACE) design is flush mounted and hardly noticeable. The micro-flange grill is held on by strong magnets and is spray paintable to match the ceiling. Built-in dog-ear brackets make installation quick: cut an 8.12" hole, wire the speaker, set it in place and tighten the front screws. The speaker measures 8.76" in diameter with 4.5" of mounting depth.
Sold as a single speaker with a spray-paintable magnetic grill. Passive - an amplifier or receiver is required. Backed by OSD Audio's 10-year warranty.

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?

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. [email protected].

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.

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.

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.
Customer Service • 12/17/2019, 2:17:43 PM
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...

Hi,
Some of the questions relate as to whether the speakers are in stock. I am able to place the speakers in my basket; could you please confirm if they are, or are not in stock for purchase.
Thanks,
Mark

Hi Mark:
These recently came in from our factory. They are sold as each. We have plenty in stock (as well as the ACE870 8" version).

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?
Customer Service • 12/17/2019, 2:17:43 PM
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.
