Features & Specifications

In the single speaker category the MK670 sports a truly innovative design. The MK670 single speaker includes an angled 6.5” Kevlar® woofer, set at a 15° degree angle and a pivoting 1” aluminum dome for amazing imaging and staging. It is by natural the perfect setup for Dolby Atmos firing down speaker setup. The critical high and midrange frequencies are pointed toward the listener, not the floor, so when your video tracks left to right, the sound tracks right along with the video. With power handling up to 175, this is an ideal speaker to build a great ultimate home theater.

Why an Angled Speaker?
The beauty of an angled speaker like the MK670 is that you can tailor the sound to your room. Suppose your sofa is not positioned directly below your ceiling speakers. The angled speaker allows you to point the audio directly at the "sweet spot." Also sometimes customers do not have room for an in wall center channel and use three MK670 in-ceiling speakers for front surround. This configuration is especially helpful when the listening area is close to the rear speakers.

The Power of Kevlar® !
Kevlar® brand fiber is an innovative technology combines high strength with light weight to help dramatically improve the performance of a variety of consumer and industrial products. Lightweight and flexible, Kevlar® has evolved over four decades of innovation to do everything from helping save thousands of lives around the world to helping make safer homes and vehicles to helping land spacecraft on Mars. If it needs to be light, strong, or safe, it needs to be Kevlar® . Kevlar® Cones are featured on both our MK Spitfire and Kevlar® Series Speakers.

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.

Paint the Grilles for a Custom Touch!
Many of our customers like to paint the grille of their in-ceiling speakers to match their room décor. Painting the grilles/trim won’t harm your speakers but be sure to use spray paint; never a brush. Brushing the grilles can clog the holes and interfere with sound quality. We also recommend using a fine spray paint gun, the inexpensive kind that you can pick up at your local hardware store. Our in-ceiling speakers also come with a paint shield to help guide you.

For a retrofit installation, no construction bracket is needed.


Other Product Info

Introducing LCR Ceiling Series Speakers. With this revolutionary design you can get imaging and staging that would be lost with regular, down-firing ceiling speakers. We accomplish this because our woofers are set at a 15° degree angle. The critical high and midrange 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.

My question is this. I am redoing my entire attic and want to include in ceiling speakers. The issue is that I am going to have spray foam insulation. What is the best way to protect the speakers in the ceiling with the spray foam? Is there an incasement that I can put the speaker in.
By Customer Service - Q&A on September 24, 2012

Hi Chris,
Sounds like you’re referring to a back box. While not required, back boxes can enhance the performance of your in-ceiling speakers and reduce sound carrying to other rooms or floors up to 10 dB. We sell the BB6, which would improve the sound pressure level as well as protect the speakers from the insulation. Take a look at our learning section for more tips in installing in-ceiling speakers:


By Kevin from hawaii on October 13, 2011
do they come with a new construction bracket?
By Customer Service - Q&A on October 17, 2011

No these do not come with a new construction bracket, nor do they require one. If you prefer to use a new construction bracket, the appropriate model bracket for this speaker is NCCB6-K.

Does this speaker require a back box, if so can they be purchased separately?
By Customer Service - Q&A on November 10, 2011

No it doesn't require. Your drywall is the back box.

By John from Utah on February 19, 2012
How do you keep insulation from getting on these speakers? I have blown-in insulation and I have to use 20 of these babies.

Hi John:

Here is a affordable solution...

It is like a sleeve that covers the speeaker protecting it from loose debris getting behind the grill inside the basket...

Filled the need perfectly
December 11, 2016
The 6.5" angled speaker was perfect I almost purchased the 8", but I believe that would've been to much. I'm using three (LCR) in a basement with an 8' ceiling that is 16' X 20'. I'm using 2 MK650 for my rear surround. The highs are good as well as the bass I actually need to back the bass of a little overall I'm very pleased.

great speaker for home theater and great price
March 22, 2013
Its good to do your research on your off-brand speakers. You could save yourself a lot of money. I was a little skeptical on buying this brand over other brands mentioned an avsforum. Haven't heard much of these speakers, but liked what I saw listed on their specs. The specs matched up pretty similar or if better to the Bowers and Wilkens CCM663 (found at BestBuy Magnolia to be demoed). I decided to give the MK670 a try and if I didn't like them, I would just return them. Stuck them in the ceiling, and never thought twice about taking them down. Comparing them to the CCM663, I found the MK670 to sound slightly more tinny than the CCM663, but was fixed when changing the impedence from +3db to 0db. Also wasn't bassy with the +3db, but are you really expecting a lot of bass out of your ceiling when the setup is for a home theater system. That's what a subwoofer is for. Bottom line...if you have the money, go ahead and spend it on some overrated, overpriced speaker. My guess is that you came to this website because you aren't made of money and you liked where the price point of these speakers are at. GET won't be disappointed. BTW, I bought 3 for my fronts (sold individually), and the MK650 for my rears (sold as a pair). The room these reside in is a space of about 20x24ft room.
price easy installation
not enough bass to be used as a whole house speaker.
Best Uses:
Home theater only. I wouldn't use these as a whole house speaker.

Exceeded my expectations
January 25, 2015
I am using these as my dolby atmos speakers in my surround sound system. At first I hooked them up to my speaker mains just to audition them to hear how they sound. Very nice sound, way better build quality than i was expecting. Overall very pleased with this purchase from OSD!
Sound and build quality for the price.
None, so far.
Best Uses:
These will be my dolby atmos speakers in my system. After listening to them, I realize these are a bit of an overkill for the use I am using these for.

Good speaker
February 20, 2014
So far these are great speakers, using as the R,C,L. Running off a Yamaha RX-v 675. The screws for the dog ears are the biggest piece of **** I have gotten on anything. I tried to run them in by hand before holding up to install just to make it easier on me. 3 bent and every one of the other ones snapped. I was beyond irritated That i had to take the time to fix all of this. If your spending this much on a speaker I expect quality.So if you get these do yourself a favor and remove those screws go to your local hardware store and find replacements.
Worst screws everrrrr!

Installation was troublesome. Sounds great though.
November 20, 2013
Fast delivery. Sounds great just as picture on the site. However, the install screws for installing of the dog ears in order to hold it up would break off leaving that dog ear useless. Used for my home-theater setup front left center and front right.
Angle of speakers.
Like I wrote above, I ended up breaking three screw heads off due to the tight tension that is required when you install the speakers on the dog ears. I ended up carefully driving all the screws through completely then driving out then installing with no problem. The manufacturer could simply avoid this by using slightly skinnier screws or making the diameter of the dog ear hole slightly bigger so not as much torque is needed to drive the screw all the way through.
Best Uses:
Surround sound fronts.

Amazing sound
April 13, 2013
Using three of these Speakers as LCR. All I can say is wow!! They are constructed great and feel high quality. The low frequency is impressive as well as the angled design which makes a big difference. Thanks OSD!
Dog ears are a bit flimsy. cant see them holding up well if I need to remove them often.

I love the sound of these speakers
September 18, 2012
I have been researhing ceiling speakers for about a year and I decided that for the price and features, I would give these speakers a try. I am glad I did. These speakers sound excellent and I would have to paid two to three times more to get the sound that a critical listener would like. I also like the quality of these speakers.

Best Bang for Your Buck
January 10, 2012
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!

MK speakers rock!

I have 7 of the MK670 angled speakers in the lounge for the Home cinema and they are great - the IC650s are are in the bedroom and match the sound quality of the 670s perfectly. truly a great speaker. Highly recomend them to anyone.

MK670 angled 6.5? Kevlar Ceiling Speaker

Used these as the front channels in our newly constructed home lounge room. Sound is clear, with good bass tone... paired with the MK650 for surround speakers. No complaints or problems at all with them, installation was easy using the included template.
