Features & Specifications

A center channel speaker provides a clean and balanced sound experience that will enhance your home theater and surround sound significantly. The In-wall Center Channel Speaker MK-IW550 LCR available at Outdoor Speaker Depot comes with powerful Kevlar® woofers, a pivoting aluminum dome tweeter and crossovers that will give you the sound of deep bass and laudable top-end frequency response. Many users employ the MK-IW550 LCR speakers as the front channel on sophisticated home theater systems with the center channel mounted horizontally below the TV and the left and right channels mounted vertically on either side of the TV. Some of the In-wall Center Channel Speaker's features include butyl rubber surround, a 1-inch pivoting aluminum dome tweeter, two 5 1/4-inch Kevlar® woofers, an integrated rear dust shield and more. The frequency response is 29Hz - 20kHz with power handling of 15-150 Watts, 90dB sensitivity and impedance of 8 Ohms.

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 MK550LCR Spitfire Ultra Reference Series are the best in-wall center channel 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 responses to your room arrangement. You won't find yourself wishing for more or less treble, mid-range or bass output from one speaker just because you don't happen to sit right between them.

Our Better (T52LCR) and our Best (T53LCR). There is no pricing on this line so you will have to contact Outdoor Speaker Depot Customer Service for pricing. TL/5065H

Hi Nate: We are in transition with our OSD Audio LCR speakers, We are changing over to newer more popular Trim-less design versus the standard frame. We are also in the process of adding a dual 6.5 with Tweeter that will fit in between two studs like our current models. You can also check out our OSD Audio Premium Black Series LCR speakers they feature Better (point 2) and the Best (point 3). Check out our and click on Black Series/In-Wall/T53LCR and T52LCR. The 53 features dual 5.25" Carbon Fiber Woofers and 1" Ceramic-coated Aluminum Metal Dome Tweeter. The 52 features dual 5.25" Graphite Mineral filled Poly Woofer and a 1" Silk Soft Dome Tweeter. Both our Perfect Edge Trim-less Grill design. There is also a matching 8" 2 way for Left and Right front channel with the center MTM (Mid/Tweeter/Mid LCR). We call both the T53 and T52 LCR speakers because they can be used as full front stage Front Right, Center and Left speakers. Note all the Black Series speakers are in stock, but you need to call for a price from our Customer Service reps. TL/5020

from Ottawa, IL asked:
June 18, 2017
Can this speaker be used as a sound bar, without adding any additional speakers? Can this speaker be hooked directly to tv?
1 Answer
HI Randle: This speaker is a true LCR speaker but you need two of them to create a stereo right and left stereo setup. You need three to duplicate a Sound bar that features Front Right, Center and Front Left channels 1, 2 and 3 for a true surround 5.1 or 7.2 system. Your TV typically has a RCA low level pre amplified signal output connection. Which means you have to connect to an amplifier before the speakers or to Powered speakers. This is typically a right and left stereo output on the back of the TV. You can turn your internal speakers off in the setup menu. You really want to start with Audio Video Receiver that has 5 or 7 discreet surround sound channels. You would connect three of these speakers to the Receiver for your front stage. You can buy 2.1 or 3.1 sound bars with and without power. The entry level Soundbars also include a Subwoofer with a wireless connection between soundbar and Powered Subwoofer. They also may feature a DSP, Digital Sound Processor circuit which gives you simulated surround. Just depends on your budget and how good a system you want. You have lots of options. TL/4429

Can I pair this speaker with the iw545. I would like to use the mk as the center and the iw545 as the left/right.
1 Answer
Hi Harold, The IW545 could work with this speaker, but I do suggest considering using Kevlar speakers for all 3 left, right, center. I suggest either using 3 of the MK-IW550 or a pair of the MK-W850 for the left and right. CS 3031

from Minneapolis, MN asked:
March 23, 2014
Hello, can you confirm whether these can be mounted horizontally between studs? My studs are 16" on-center, which leaves approximately 14.5" of actual space between the studs. The cut-out dimensions for this speaker is listed at 15 1/16" which gives me the impression that it will not fit between regular stud framing. Thanks.
1 Answer
Hi Duc, If there is only 14.5" in between studs, then the MK-IW550 would not fit unless you mount vertically. Another option that you could use for your center channel is the MK670 which is an angled in-ceiling speakers. CS 2563

hi. I am looking at this center speaker to go above the fireplace (gaz). the space behind is deeper than a regular dry wall (1~2 feet) and there is almost nothing inside (no insulation). Would that be ok and provide good sound? what would you recommend? thanks
1 Answer
Hi JM, Good question. Will the area above the fireplace get hot? How often do you use the fireplace? If it will be used often and the area in the wall where the speaker would go does heat up, it may not be safe to run the speaker in that location. But that would depend on how much use that fireplace gets. Do you have the option to run in-ceiling speakers? -BM 2503

from Austin asked:
February 20, 2014
I have a difficult space to accommodate LCR channels in my home theatre room. My choices are either 3 angled LCR's (MK 670's) in ceiling, 2 mk670's for R/L with a MK IW550 (or IW550) in a fabricated box over the TV (TV is mounted relatively high). or (at a squeeze), doing IW 550's (the MK IW 550 is too big) for LCR in wall for L/R and in box above TV for center. Room is 15 foot by 20' and it will be a 7.1 set-up with audience 13 feet back from screen. Thoughts on what would yield the best. Many thanks
1 Answer
Hi Peter, The MK-IW550LCR is a great speaker, but for your application I would recommend doing the MK670s all around. They are less visible when installed in-ceiling and will give you crisp, high-definition results. Plus, the MK670 has a larger woofer than the MK-IW550, giving you more bass and overall power. Not to mention the standard IW-550LCR is no longer available, but the MK-IW550LCR is. Let us know if you have any further questions. Thanks! -BM 2500

What option do you recommend for Left, Right and Center speakers. All speakers are going to be put in a back box with 2" x 6" interior wall. Note: Wall unit is not built so I have many options. Option 1 Left and Right will be MKW-850 & Center speaker will be MK-IW550LCR Option 2 Left, Right and Center speakers will all be MK-IW550LCR Thank You
1 Answer
Hi Chris, I would suggest going with option 1 with a pair of the MKw-850s and the MK-IW550LCR. The MKW-850s are a better choice to use for your left and right channels because they will add more power up front than you would get with 3 of the MK-IW550LCRs. Plus, they have matching tweeters with the IW550, so you'll have no tonal change. What are you planning for the rears? In-ceiling or in-wall? CS 2475

from Oklahoma asked:
December 4, 2013
I bought this speaker to go along with the OSD-ICE850 and OSD-ICE870 speakers which are mounted in the ceiling. However, my contractor said he will not be able to mount the speaker in the center of the TV because of the way the studs line up on the wall. My best option at this point is a center channel speaker that sits on the fireplace below our mounted TV. Is there a speaker that you can recommend that would go well with the other speakers I purchased? I do not see any center channel speakers for sale on your website that aren't in wall speakers.
1 Answer
Hi Brent, While we don't offer any tower/floor standing speakers at the moment, one option which several of our customers have done, is to simply build a box to house the speaker, essentially making it a tower speaker. Is that something you or your contractor has the ability to build? -BM 2376

I bought 3 of these speakers but I wont be able to install the center channel in the wall (there is a stud right where it needs to be) so I wanted to ask the following questions: 1. What is the recommended size of a box to build around a speaker of this size? 2. Can I paint the entire speaker (grill and surround)? Recommended paint type? Thanks!
1 Answer
Mark, Good questions! 1) You should probably build a box about one cubic foot including displacement of the driver. 2) No. You don't want to paint the woofer, surround or internal baffle. The speakers come with a paint shield. You will just paint the grill and trim. -BM 2076

The wall that my TV is mounted in is an outside wall. It is framed with 2x6, and has blown-in nu-wool insulation in it. Can I still use in-wall speakers? Can this be installed directly into the wall, surrounded by the nu-wool? Thanks.
1 Answer
Hi Noah, The nu-wool could pose a problem when mounting the center channel speaker as it can get into the internal components. We would recommend customizing a back box to protect the speaker. CL/MA 1869

A few questions: 1. How much better sounding is the MK-IW550 vs. the IW550 ? 2. How would two MK-IW550's for front Left/Right sound with a normal IW550 as the center channel? (cutout of MK is too big for horizontal install as a center speaker or I would consider using 3 of the MK's - dont wish to cut studs). Are the timbre's compatible between these speakers (MK and non MK 550)? 3. Would like to find good front left/right speakers for loud stereo playing vs. whimpy TV watching speakers. Suggestions? Thanks
1 Answer
Hi Mark, The MK-IW550 and the IW550 are both excellent in-wall left center, right speakers with Kevlar woofers and aluminum dome tweeters. The difference is that the MK-IW550 has a slightly higher power handling (175W verses 150W). They both share the same components and timbre match so you could install these speakers just as you describe. You should be able to take a notch out of your joist/stud (just a small piece to fit the MK-IW550LCR for a custom install). Installing 3 x MK-IW550LCR for your front stage would give you an ideal front stage and blow the wimpy sound of your TV out of the water. CL/MA1766

1 Answer
Hi David, We do not offer a back box for our center channel, although we do give the measurements and often customer design their own. Building a back box is a great idea because it improves the quality of sound by adding to the sound pressure level (spl) CL 1299

Hi - I bought these speakers based on the description that indicates this model features contour switches. The manual also makes mention of contour switches, however, I am unable to locate them. Where are the contour switches on this model? Thank you very much
1 Answer
Hi R: We recently changed the bullet points on the product page for this speaker. It does not have contour switches'. Our IW550LCR, the model just below this one does feature contour switches. We would have no problem swap out the two units. Please contact Brennan at to arrange it. The mounting holes are very close and you could mount it to see how you like it before making a final decision to switch. Please contact me to discuss your options... TL

Can this Center Channel Speaker be mounted vertically? Because, I don't have the space between the studs to mount it horizontally.
1 Answer
Hi Anthony: These are designed to go between standard studs to mount horizontally. But you certainly can mount it Vertically. We normally recommend using three of these for the front stage. The right and left would be mounted vertically on either side of the TV while the center would be mounted Horizontally (but vertically is acceptable) under or even above. The Tweeter pivots 15 degrees. What are you using for your right and left speaker? TL

from Spring, Texas asked:
July 8, 2012
While using the MK-IW550LCR as center speaker - shielded - should I be concerned about using the MKW-650 as L and R Front speakes in close proximity to my flat panel HD wall mounted TV? I don't see in the spec's where the MKW-650's are shielded.
1 Answer
Hi Dwayne: The magnetically shielded feature is from the old school technology that shielding was needed when these were mounted near a CRT screen that was affected by the magnetic field of the speakers. There is no such issue with the new Flat Panels. But if you are concerned, think about using an additional pair of MKIW550LCR, one for the right and one for the left mounted vertically on either side of the panel. The center channel would be mounted Horizontally. You just have to make sure the center of the TV is directly between the center of two studs in your wall. That way the speaker will be centered to the TV horizontally. We recommend using the three as a step up system. Check the images included with the Product page of the MK-IW550LCR for more information. TL

Can I use this as a in ceiling center speaker?
2 Answers
Aaron, Yes you can use this in the ceiling, its mostly visual preference to have a retangle or square shape in the wall and a round in the ceiling. There will be no difference in sound quality. CL
Submitted by: Customer Service - Q&A on December 20, 2011
Hi Aaron, The speaker will work; however, you would have to mount the speaker almost directly above so you can aim the tweeter to your listening area. You did not mention your choice for your right and left speaker for the front stage. I can assume two things: 1) one you are using two in-wall or external speakers for the right and left speakers which will be located near the monitor/TV, or 2) you are using a pair of in-ceiling speakers that would also have to be placed almost directly above your setting area. A better choice would be our ICE870 LCR 8" angled in-ceiling speaker for the center channel (and left and right as well if you have not yet made a decision). This angled speaker would allow you to mount it closer to the wall above the monitor/TV with better orientation to your left and right speakers. It is an 8-inch speaker versus the dual 5.25" so the output is similar. Typical in-ceiling speakers (or in-wall) need to be placed 3 feet from the nearest wall. The angled speaker allows you to cut that distance down to a foot. I hope that helps. TL
