Features & Specifications

Customers tell us that once they install the OSD-MK650, they are completely knocked out by the sound quality. Part of our Spitfire Ultra Reference Series, this 6.5" speaker consistently outperforms speakers that cost hundreds of dollars more. The MK650 includes the high-end feature of the MK850 in a smaller 6-inch speaker size. This extremely well crafted in-ceiling speaker delivers a high end audio without the high end price. Like our entire MK Series, the MK650 is for customers who are picky about their sound and listen to every sonic nuance in music and sound tracks.

Underneath the Grill
We label the MK our Ultra Reference speakers because of the premium technologies used such as a Kevlar® woofer, pivoting aluminum dome tweeter and a sophisticated crossover network. These components combine to provide deep bass and exceptional top-end frequency response. All OSD Audio speakers are built with quality materials but there are some materials, such as Kevlar® , that are ideal for cone woofers. First developed in the 1960s, Kevlar® has a super high strength-to-weight ratio that responds note for note without coloration, even when you crank up the volume. In addition, the MK650 has front-mounted contour switches that allow users to tailor frequency response to their room arrangement, and therefore compensate for wood floors, stone floor, carpet, etc.

Common Applications of the MK Series
With its 6-inch Kevlar® woofer and high end components, the MK Series is not for background music. You will hear detail and customers tend to use the MK Series in home theaters or listening rooms. The MK650 performs excellently in medium to smaller home theaters and comes complete with mounting templates/instructions and paintable grilles/frames.

For a retrofit installation, no construction bracket is needed.

Kevlar® is the best component for woofers. It responds note for note without coloration and has big cranking power so you can dial up your system for higher listening levels.

November 10, 2017
My media room is 12x17 with a 10' ceiling. I'm considering 2 sets of MK650 mounted in the ceiling for music mostly. Are the MK650 big or small for this room?
1 Answers
HI Juan: The two pair of MK650 are an excellent choice. Typically you want to mount an in-ceiling speaker 3 feet from an adjacent wall. One option would be start with the 12 foot wall and have one speaker 3' in from the 17' wall and 4' foot in from the 12 foot wall so your first pair would be 6 foot apart. Then just duplicate the second pair coming off the opposite 12 foot wall. On the first pair wire them Right and Left. On the second pair start with Left than right so the left speakers are cady corner of each other as well as the right speakers. Please let me know if you have additional questions; tim@osdaudio.com TL/4641

Can I paint these grills and trim on both MK-650 & MKW-650's?
1 Answers
Hi Adam: Yes you can, just make sure you remove the cloth glued to the inside of the grill. This works as a paint shield and needs to be removed after you spray paint. TL/4573

I can't decide between these MK650s or the MK690TT speakers for my two rear left and right, ceiling mounted speakers in my movie room. Which would you recommend? I see that the MK690TT have a switch so that I can set 4 ohms and use two of them.
1 Answers
Hi Aaron, When a speaker has dual tweeters, it is almost like having 2 speakers in one. You are able to connect two lines to the speaker and each tweeter acts as a left and a right channel. If this is for a home theater, I would suggest using a pair of the MK650's. CS 2436

March 17, 2013
Hello, I am getting ready to order in ceiling speakers. It is for a 5.1 surround setup. These speakers will be going in the living room ceiling (8' ceilings) (keep in mind the living room, dining room and kitchen are all open) I was planning on using mk670 for LCR. Where I am stuck is if I should stick with MK650 for the rears or should I go with MK850? Thanks
1 Answers
Hi John, If the layout limits you to a close proximity to the couch, go with the MK650s for rear surround. You would not need the MK850, even though you have an open floor plan. You could use two more MK670s if the location of the speaker is greater than two feet away from directly above your seating/ listening area. For even more sound coverage, you could go with two MK690TT ceiling speakers connected as a stereo pair. CL/MA 1708

September 24, 2012
I'm building a screened in porch 16' x 14' and was looking at putting a couple of these in the ceiling. The ceiling has a peak in the center so they will naturally be angled toward the center of the room. Wondering if these are a good speaker for that, and any advice on the best layout of speakers. Seating will be mostly around the edge of the room.
1 Answers
Hi Jeff, These speakers are a great choice for that space. The pivoting tweeter allows you to direct the sound right where you want it. Depending on how high the ceiling is you could even go to an 8" speaker like our MK850s. As for layout, it's bet to have the speakers relatively centered and evenly spaced. CL/MA 1306

DanR
from Eugene, Oregon asked:
July 31, 2012
I recently moved into a new home and wanting to install a 7.1 surround system. I have no where to place in-wall or wall mounted speakers. I'm going to install all speakers as ceiling mounted. My ceiling is already angled at 15 degrees (lucky me), so don't need the angle speakers, and I was looking at the MK650's to use for the L/C/R and all surround speakers. Would this be a good choice for all the speakers or would a combination be better? Also these will be installed where there is a huge attic with blown in insulation, would I need some type of box around these speakers to help with the sound, keep the insulation off the speakers?
1 Answers
Hi Dan, Based on your scenario, an angled design would still be ideal for your LCR front stage. Our ICE670 ceiling speakers would be perfect for a 7.1 system because the angled design gives you ideal placement in the ceiling and allows you to install them closer to the wall just above the TV. You can then pivot the tweeter to create just the right sound image. We would then suggest the ICE650s for your middle and rear pair wall for an awesome surround sound experience. You will need to protect the speaker from the blown-in insulation either with a cover or a back box. The OSD BB6 back box would be an excellent choice. CL/MA

July 18, 2012
Hi I recently bought a set of these and installed them very easily. While screwing them in I accidentally punctured a whole in the outer foam ridge of the speaker with my screwdriver. The speaker sounds fine right now. Is there anything that I can do to repair it so it doesn't continue to tear along the rest of the rim of the speaker?
1 Answers
Hi Tony: The surrounds are made of Butyl Rubber. You can use either super glue (as long as it says it works with rubber) or rubber cement. Send a picture of the damage to tim@osdaudio.com so I can check with our technician to see if he has any other ideas. TL

I have a Yamaha HTR-5760 7-channel receiver. I need to purchase 2 rear in-ceiling surround sound speakers for the family room and three other pair of in-ceiling speakers for my living room, dining room, and covered porch. Are the MK650 Spitfire the proper speakers? Thank you.
1 Answers
Hi again: First lets talk about the four speakers for your surrounds in the family room. First as stated in the previous answer to your first question I would suggest our MK690TT a dual voice coil, dual tweeter and dual application speaker. This features 4/8 ohm switch which allows you to connect only one of the voice coils and use two of speakers for a stereo pair. They would be placed above and just to the right and left of your listening area. Channel 6 and 7 are considered side surround channels. These would be available for either the surround channels when playing your 7.1 system (Source B from your DSM4). They would also be very effective when switched to full range for your music when selecting source A for zone 4.In both cases due to the dual tweeters you have a broader dispersion pattern for the high frequencies.One last point you will need one of your impedance matching volume control to connect between your speaker selector and the MK690TT speakers to properly match with the other four zones. For the actual rear surrounds channels 4 and 5 connected directly from the Receiver I would recommend our MK670 LCR speakers which offer lots of flexibility in placement due to the 15 degree angle of the internal speaker and pivot of the tweeter. These should be located five feet behind the listening area closer to the right and left wall angled back towards to listening area. The MK650 or even the MK850 would be the best choice for your living room and Dining room. The MK Spitfire 650 or MK850 would also be a good choice for your enclosed patio as well. These are Weatherproof on top of being our best sounding speaker series. Again I would be more than happy to provide an illustration of this system. I really like the possibility of having you listen to music in the family room playing both the MK690TT (from speaker B of your receiver through the DSM4) as well as your from stage speakers connected to speaker A. As you can tell I get excited at suggesting some of the key features they we offer here at OSD Audio. Thanks for considering OSD Branded products. Good luck... TL/MA

Tom, The ICE650 are the Kevlar and the MK650's are Kevlar as well. The MK650s are our highest end speakers and have a larger magnet than the standard ICE650 Kevlar. If you are looking for higher fidelity, the MK650's are top of the line. CL/MA

Hi Tom: These speakers are very close. Either will work in reproducing the surround channel information. I like to recommend our MK670 Angled speaker which gives you more mounting (or placement) options in regards to your seating location.The best placement is two to four feet above and behind your seating location. The angle speaker will also allow placement closer to the wall. Typical in-ceiling speaker need to be three feet from the wall to avoid reflection. The key is to be able to face the pivoting tweeter directly at your existing viewing/listening postion. TL

Perfect for rear surround
I'm using 2 MK650 for my rear surround. Im using three 6.5" angled speaker (LCR) in a basement with an 8' ceiling that is 16' X 20'. The highs are good as well as the bass I actually need to back the bass of a little overall I'm very pleased.

Nice for the price
Bought these speakers a few years ago. Very nice construction and materials. And overall an impressive and clean and mostly accurate sound. My question is simple - does OSD test and audition the ceiling speakers in the ceiling or in a wall? My only disappointment is the off-axis coloration of the midrange (the most critical range). When seated directly below the speakers in the sweet spot they sound terrific. But when off-axis they have a slight coloration of the mids. I sent a note to OSD and they quickly replied these were the best speakers they make. Again, extremely impressive performance, especially for the money when on-axis (if not a bit metallic in the highs). But off-axis which is almost all of one's listening time, there's some vocal coloration. Playing with the switches did not help much. Most listeners may be fine with this but critical listeners with other quality sound systems may not be as pleased.
Merchant Response:Mike - thank you for your comments on off-axle position, our speaker's tweeter is swivel so you can adjust it to your listening position. Another option will be using the Angle speakers which can be installed directly point to your listening position.
ProsValue, very clean and mostly accurate sound
ConsMidrange slightly colored off-axis, bass not as tubby as specs suggest, highs a bit metallic

WOW is about all I can say. First of all this company is fantastic on their delivery. I ordered on a Tuesday and had them Wednesday, never had such fantastic service. The product is everything they said and MORE. Easy to install and the sound is fantastic. I ordered 4 speakers total for a family room surround sound system and the sound is really more than I expected. I will definitely order form Outdoorspeaker Depot again!! In fact I am waiting for them to get wireless outdoor speakers for my patio which I will order once they are in stock. Keep up the fantastic customer service guys and a super product.
