Features & Specifications

There´┐Żs a reason our ACE870 has so many rave reviews´┐Żcustomers love the look, sound and power of this heavy-duty Atmos-ready home theater ceiling speaker. Designed for high-end audio systems, larger home theaters or commercial spaces such as bars or restaurants, the ACE870 can handle up to 175 Watts of power so you can push volume levels without any sign of stress. The beauty of the MK870 is in the design. The mid-bass driver is angled at 15 degrees, which gives you more placement flexibility than standard in-ceiling speakers. This makes the MK870 ideal for Dolby Atmos surround sound systems because you can place the speakers in multiple places to create an all-enveloping 3D sound experience.

In addition to crisp, detailed mid and high frequencies, this single ceiling speaker kicks out impressive bass due in part to the 8´┐Ż Kevlar woofer and heavy-duty and efficient magnet structure that focuses energy within the voice coil gap. Other audiophile features designed into the MK870 include front-mounted contour switches, so you can tailor bass and treble to your preferences as well as butyl rubber surround that gives the speaker more excursion capability for deeper bass and wider frequency response. The MK870 installs easily into ceilings with four easy-to-lock-in dog-eared brackets and includes a cut-out mounting template.

What Are the Advantages of Angled Ceiling Speakers?
In a word´┐Żflexibility. Not every room or space is the ideal setup for custom home theater sound applications. When traditional in-wall or on-wall speakers are not practical or even possible, in-ceiling speakers can be a great alternative. The problem with in-ceiling speakers is noticeable in a LCR (front stage) setup, because they need to be installed away from the wall to avoid sound reflection. This can create a disconnect between the screen and the sound coming from the speakers. An angled speaker can be installed closer to the wall, just above the screen, and the speaker assembly can be aimed toward the listening area. The angled design is also ideal for a Dolby Atmos down-firing speaker setup where overhead sound is an essential part of the 3D experience.

What Is Dolby Atmos?
Just when you think that home theater surround sound couldn´┐Żt possibly be better, along comes Dolby Atmos. Originally developed for commercial movie theaters, Atmos expands 5.1 and 7.1 surround sound with multiple speakers placed overhead and around the room to create an immersive 3D sound experience. With an Atmos-capable receiver, sound does not have to be assigned to a particular speaker channel (i.e., LCR) but rather individual sounds can be isolated and specified as to where they originate from and where the sound travels (these are called audio objects). The Atmos system plays these objects back within a virtual 3D space and the result is an unforgettable acoustic experience. Sound will seem as though it originates from your room so footsteps feel as though they´┐Żre coming toward you. The sound of wind will swoop from across the room, not to mention what a car crash or explosion would sound like. Because overhead sound is a key component of Dolby Atmos, adding in-ceiling speakers such as the MK870 can enhance the sound quality because they can be placed strategically around the room and angled toward the listening area.

What Is Butyl Rubber Surround?
The Surround is just one of the integral parts of the speaker's motor structure, and butyl rubber has been the choice of speaker designers looking to optimize the sound based upon materials that go together. Butyl Rubber gives the speaker more excursion capability, allowing for deeper bass with a wider frequency response, and its shelf life is closer to 25 years compared to the 12 to 15 years of foam. Do I Need Special Cable for In-ceiling speakers? Wiring is not included with the MK870. 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 cannot 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, and the high-quality plastic jacket is also very flexible so it's easy to run the wires inside the wall.

Hello. I have a 7.2 system mapped out. I am not sure what exactly is being said on one of the q&a Would you not suggest using 7 of these speakers? I should be looking at these for mains and a different model for center and surrounds? Thanks
1 Answers
Hi Craig: These speakers were created as Front Stage LCR speakers Left, Center and right. But they also work very well as both surround speakers and effects (like ATMOS or DTS:X). The key to any home theater system is the placement of the speakers so you can aim all the tweeters directly to the optimum viewing and listening area. We would recommend using the ACE870 for your front speakers and the ACE 670 for your Surrounds and Effects speakers. The question I think you were referring to was regarding an older speaker the ICE 870 and ICE 850 TL/4253

I have a Marantz sr6011 9.1 atmos enabled receiver, Klipsch Reference Premiere speakers including one set of Klipsch RP 140-sa Dolby enabled speakers. I would still like to add ceiling dolby atmos alon gwith my Dolby enabled speakers. Considering I have a have a high end system, do you feel these speakers will complement the system I already have. The price is certainly right. Just want to make sure they will complement my system.
1 Answers
Hi Don These would be perfect match with your Reference series speakers. Both feature metal dome tweeters. The ACE are 92 dB sensitivity and KLIPSCH are at 97dB. So you would haved to raise the volume levels up on the ACE speakers. You could get away with the ACE670 if you wanted to save additional dollars. Most of the up firing Dolby Atmos speakers are 3.5" full range drivers. Good choice TL/4571

Can these be ceiling mounted on a outdoor terrace? I know you have an outdoor line of speakers, but there seem to be more options and maybe even quality on those that are not outdoor rated by your website.
1 Answers
Hi Idilio: These are an excellent choice, you can mount these in your application but you want to take some precautions where you might want to weatherize it your self including putting a bead of silicon on the back of the mounting flange and maybe covering some of the exposed metal components on the back side around the input terminals and crossover parts. This is a great speaker... TL/4294

I have 7.1 system and wanted to use these all around due to the lack of good wall locations. Can I use one of these for the center, or is there a better option?
1 Answers
HI Jack: These are an excellent choice. The angled speaker was first created as an LCR front stage solution. But the angled speaker provides more flexibility for ceiling placement for Rear Surrounds, Center Surrounds and Atmos/DTS:X Speakers. The key to any in-ceiling speaker setup for Home Theater is to have the ability of aiming the tweeter directly at the optimum viewing/listening area. The 15 degrees of the mid woofer plus the 5 degrees for the pivoting Tweeter providing 20 degrees total.These new top of the line ACE-870 feature the same Kevlar cone and metal dome tweeter as our MK series with the new perfect edge Trim-less grill design (held on by multiple extra strength magnets). And yes one of the speakers will work fine as your center channel. TL/3886

from TN asked:

I'd like to build a back box in the ceiling for the ACE950 speaker. What size box should be built for the ACE950? Thanks.
1 Answers
Hi David, A back box is always a good way to go if you have accessibility and the room for a box. These speakers are designed to work in a wide range of enclosures so it is not critical to have a dedicated enclosure size. So your enclosure size should be roughly double the size of the speaker box it came in. Again you are at the mercy of the ceiling you are installing these in as far as space available. You also might want to pickup some fiber fill (material used for pillows) and use this to tune the speaker once you have built your enclosure. The more fiber fill you add, the more you "fool" the speaker into thinking the enclosure is larger. I hope that helps, feel free to call us for further clarification. There is plenty of information on Google for building enclosures (YouTube as well). Good luck TL/MA - 1545

1 Answers
Danny, At this time we currently don't have an in ceiling center channel. Sometimes its great to do 3 angled for your front and a regular pair for your rear like 3-ICE870's and 1-ICE850 but -in that 9", in the trim less we do not have a matching in ceiling center channel or angled speaker. CL

Comparing this speaker ...
Comparing this speaker with Speakercraft AIM 10 speaker, the fit & finish is excellent, all made of high quality materials. I like the Kevlar woofer which produce clean powerful bass, the contour switch really have good + and _ db effect when you adjust it. I replace my NHT tower speaker with a pair of ACE950 and I can═t tell the difference either listening to music or watching movies. Also the price is just unbelievable, the AIM10 speaker is $1500 a pair.
