Features & Specifications

OSD-MKW-650 Ultra Reference In wall Speaker - This 6.5" wall speaker outperforms speakers that cost hundreds of dollars more. Premium technologies such as a Kevlar® woofer send chills down your spine as you listen to your favorite music or movie soundtrack, while the pivoting aluminum dome tweeter delivers outstanding top-end frequency response. The contour switches let you tailor frequency response to your room arrangement, so you won't find yourself wishing for more or less treble, midrange or bass output just because you don't sit in the "sweet spot." There is simply no better price-performance ratio speaker out there.

For a retrofit installation, no construction bracket is needed.


Other Product Info

With a look deriving from famous World War II British Spitfire Jets, a new sophisticated crossover and the best component materials available, the MK650 Spitfire Ultra Reference Series are the best ceiling speakers on the market. Premium technologies such as Kevlar® woofers, pivoting aluminum dome tweeters and sophisticated crossovers provide deep bass and exceptional top-end frequency response. 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. The contour switches will let you tailor frequency response to your room arrangement. You won't find yourself wishing for more or less treble, midrange or bass output from one speaker just because you don't happen to sit right between them.

do i need to make a case inside the walls for these? and the mk-iw550 center speaker? or any other ideas?
By Customer Service - Q&A on July 6, 2012

Hi Petter:

It depends on how much room you have behind the speaker. In the US I would know the area behind the speakers would be roughly 10.16cm deep and 39.4cm wide. And typically there would be additional fire breaks (cross studs) above an below the speaker. The speaker itself usually provides an effective seal with the Sheetrock it is mounted to. It does not hurt to add a little fiber file around the speaker to fill the cavity. Certainly if your application has no enclosure on the backside of the intended wall you would need to custom build something. All our in-wall and in-ceiling speakers feature an infinite baffle so it can fit into almost any enclosure size. The Fiber fill helps fine tune the installation. I hope that helps

I have a 11'x16' entertainment room in my basment, has 7' ceiling, wondering how many speakers i should use and where the best place is to install them
By Customer Service - Q&A on January 28, 2013

Hi Paul,

What size is the monitor and will it be on a cabinet or mounted on the wall? Are you looking to do a custom in-wall/In-ceiling sound system? Can you supply a basic drawing featuring TV location and the seating options?

Are the screens and trim for the MKW-650 paintable
By Customer Service - Q&A on April 6, 2012

Bill, Yes they are paintable, we recommend spray paint only for the grills so it does not clog the holes. There is a cloth on the back of the grills that must be removed before spray painting. There is also Cutout template that doubles for a paint shield that covers the baffel while you paint he frame.CL

New Construction Bracket NCI6 - I can't find this bracket in your store. What other brackets can I use?

By Customer Service - Q&A on December 7, 2012

Hi Mikael,
We no longer carry brackets for the MKW-650 speakers becuase they are nor required for installtion. Simply install in the drywall, make the cut and then secure the speakers with the dog-eared clasps around the trim.

I want to buy 2 pairs of these for my 5.1 surround sound home theater living room (2 front and 2 rear). I already own a sony subwoofer for the lows and will be pushing these speakers with my Onkyo 509 receiver. So far I have heard of nothing but good reviews for these OSD speakers. Overall, how do you like these speakers and if you could go back and do it again is there anything that you would change? Thanks! - James
By Customer Service - Q&A on November 29, 2011

I love to brag about these speakers, they are top of the line. The MK's will blow you away with clarity and the resonace the kevlar material gives you are even better than the ice series because they have a larger magnet! Good choice, let us know how they sound once you get them in!
By Customer Service - Q&A on November 29, 2011


The MKW-650 is a great choice for the Left and Right channel of the front stage. You mentioned a Sony Subwoofer but no center channel speaker to complete the LCR (channels 1, 2 and 3 of the 5.1). The perfect match for these speakers is the MK-1W550LCR dual 5.25". It features the same cone material, frequency response, and identical tweeter as the MKW-650 speakers. This provides the perfect timbre match for your front stage. You can go with the MKW-650 for the rears as well or you can go with two each of our OSD MK-670 angled In-ceiling LCR speakers that would be ideal mounted above and slightly behind your seating/viewing area. Sometimes the ceiling has more access. This would be the optimum Custom Home Theater system that provides excellent performance at a great price. If we had to go back, we would make the exact speakers—we truly believe in the quality.

By Abel from Houston, TX on December 13, 2012
I am looking into replacing in wall speakers throughout house. Cuts have already been made in sheetrock and most have one side of speaker bracket screwed to studs. Is there a way to use the MKW-650 and secure one side to stud without having to move cut out over 2 inches?
By Customer Service - Q&A on December 13, 2012

Hi Abel,
Can you take a couple of different pictures of your speaker bracket and overall installation and send them to me at This way, I can better answer your question.

One word.....AWSOME!!!!!
April 18, 2013
I must admit I was a little skeptical when I first purchase this set, but I that all went away the instant I fired up my Denon word........AWESOME!!!!! I've now got crisp clean sound that is spacious, but not overwhelming and I can hear the detail in my music and movies the way they were meant to be heard.

Great speaker value

I bought these speakers for my theater room which I am renovating from the previous owners configuration. The speakers arrived in a few days of the order in great condition. They were easy to install and look great. The in wall installation the way to go. The sound is great . I had friends over to watch some foot ball and they were amazed at the quality of sound produced by the speaker system.So far no problems.

Excellent sound and a good value
February 20, 2013
I now own both the IW-690 and the MKW-650. I believe you can hear the increased dynamic range of the MKW and for the extra few dollars it is worth moving up to this model. As other speakers in my whole house system fail I will be back to the OSD site for my replacements.
Attractive Design, Easy To Set Up, Great Sound Quality, Easy to Mount, Good Power Output

I recently installed a pair of these with a IW 550 LCR center and with the small subwoofer from here as well. Unbelievable sound. I am a musician and sitting in the room listening to these, I heard sounds in the recordings I had never heard before through my Advents or through my Onkyo 5.1. It is an incredible experience. I am thrilled with these speakers period. The price just enhances the experience. Easy to install and magnificent to listen to
