By Customer Service - Q&A on May 31, 2012

Answer:
Hi David,

The IW750LCR has been discontinued. The model we recommend instead is the MK550LCR which features the same spun Kevlar cone material and 1" Pivoting Aluminum Dome Tweeter as the MKW850 In-wall speakers you selected. This provides the ideal timbre match for not only the front stage but for the full system. I am a big proponent of using three of the dual woofer LCR speakers for front stage. Therefore, substituting the MK550LCR for the IW750 LCR would be a great option. Here are other options that might spice up your system. We recommend an AVR from Yamaha, the new RX-V673. This model may differ for France but the key is it features a 7.2 system which means it has two subwoofer outputs. This is critical to having enough low end information for anywhere in the room. A single subwoofer tends to have dead spots between the large sine waves that are output. A second subwoofer will fill in the dead spots. OSD Audio features a number of choices, from our new PS88 (less than 11" cube in size), to our front-firing PS-12 that could be built into an enclosure. The Yamaha RX-V673 also adds a feature that calls for two additional front speakers (we recommend the MKW650) mounted two feet to the right and left of the existing right and left speakers. This would play when certain DSP effects are actively creating what they call a 7.2+2 speakers. The receiver can also simulate this effect if you choose not to add the two extra speakers. However, the key is to address the subwoofer issue and I know Yamaha is not the only one promoting a 7.2 system. The ideal setup is really four sub-woofers with one in each corner, plus in a night club setting, the option of having too much bass (that can be turned down) is not a bad thing.

I hope that helps, please feel free to contact me if I can be of further assistance. tim@osdaudio.com, Good luck!

Hello,
I'm planning to buy two MKW850 and one MKIW550LCR.
My drywall if 1" thick and the wood stud behind is 3,75", is it deep enough or should I add an extra 1,75" wood stud behind the drywall? If I make a box inside the wall, which volume is the optimum for these speakers?
By Customer Service - Q&A on December 28, 2012

Answer:
Hi Ted,

The thicker 1" drywall will help with the depth behind both the MKIW550LCR and the MKW850 when adding an enclosure. We're assuming the drywall has not been installed yet and you have total access to the studs. A simple solution would be to install a 1/4" board 24 inches high and whatever your measurement is from stud to stud wide. Then place an additional 2 x 4 fire break above and below so you are isolating the speaker from the rear wall. Then add some fiber fill (the same material used to stuff pillows) in the cavity before installing the speaker. The 1" drywall in the front will provide reinforcement as well. Just cut out your holes and install the three speakers. Please let us know if this helps.

By "chris" from "houston,tx" on December 28, 2012
My main room dimensions are 20' -0" wide by 30' - 0" in length with a gable ceiling height of about 14' - 0"
@ center! The entire room perimeter has finished wain coat wood panel to a height of about 7' - 0" I would like to install your 850 wall speakers @ a height of 9'- 0" angled down for front speakers, install 650 speakers at rear angled down, intermediate ceiling speakers in middle of room, and either a center speaker or wall mount 850 near tv monitor, also, a sub will need to be placed somewhere throughout the room. I will be using a Yamaha 663 receiver for 7.2 surround. Do you think this configuration will be sufficient? Will the main speakers height of 9' 0 " (angled down) be sufficient?
By Customer Service - Q&A on December 31, 2012

Answer:
Hi Chris:

Couple of questions,
1) Is your ceiling angled on all sides or is it flat at both ends?.
2) Where will the TV be located , on the 20 foot or 30 foot wall?
3) Will the TV be at eye level or up high tilted downward?
4) Can you do a rough outline noting furniture (prime seating area?
5) 2 Subs are recommended and your AVR accommodates that, What Sub woofers are you planning on using?
6) The Yamaha Receiver is an excellent choice, any plans for 7.2 versus 5.1?
7) The Tweeters pivot on all speakers, what is the angle of the Ceiling where you are proposing to install, sounds intriguing?

By Claude from Lewes, DE on August 27, 2012
What is the best center speaker for front and rear to match to 2 pairs of the MKW 850's? I only see the MKIW550LCR as a fit but nothing bigger?
By Customer Service - Q&A on August 27, 2012

Answer:
Hi Claude:

The MKIW550LCR is the perfect Center Channel to match for your front stage. All three speakers share the same identical Tweeter, Cone Material and Crossover Components. The MKIW550LCR features 5.25" dual woofers that added together match the cone area of the 8 inch MK850's. This provides the proper timbre match for your front stage. The Dual 5.25 inch speaker is sized to fit perfectly between two studs mounted Horizontally. We recommend either the MKW-850 or MKW-650 as your front right and left speakers or using three MKIW550LCR with one for the right and another for the left speaker mounted Vertically. For the rear depending on a choice of In-Ceiling Speakers either a pair of MK670LCR speakers or even utilizing a pair of the MK690TT . For in-wall the MK650 would be the best match. All that would be left would be to add two of our PS88 Powered Sub-woofers for either a 5.2 or 7.2 system.

Good luck

Take your Time Installing!!!!!
December 29, 2014
First of all…let me clarify that I’m by NO means AT ALL an expert on speakers and sounds, but I have perfect ears and I know what good sound sounds like. I bought these OSD speakers instead of some definitive Technology ones, because these fit the budget more…a lot more actually. At the same time however, I didn’t want to sacrifice the sound quality. I looked at mono price as a nice deal for in wall speakers, and then I found OSD online in a google search. Looked at their products and they looked really nice and were 2-3 steps above the monoprice quality. I bought two 8” in wall speakers, center channel, and two angles ceiling speakers. The house was already wired for sound so I cut my holes and there were lots of studs in the way where I wanted to mount the speakers, but there were ways of getting around this and I must say it was quite an involved install, but still very easy for a weekend do-it-yourselfer. I only write reviews on products that are really good or really bad…because I feel like that’s when people should know what they are getting into…if the product is mediocre…then who really cares. I plugged up these speakers after making sure they worked beforehand…. A little about my setup: Non load bearing wall…each stud is 24” apart…no insulation…speakers are 78 inches apart and the center channel is right in front about 10 inches lower than all the other speakers. I had a whole roll of dynamat I used 8 years ago for my car and also some sound foam material…I used that on the inside of the walls behind the speaker and on the wall the speaker was mounted to keep any vibrations down and keep the sound projecting forward. I put a piece of 2x3 about 6 inches above the speaker so that the dog ears could still grab the sheetrock, and drilled pocket holes in the so that I could brace them to the adjacent studs. I used foam to fill and gaps and then used the dynamat material to seal it off. This created a complete enclosure around each speaker in the wall for better sound…now the sheet rock wasn’t so porous because of the mass loaded walls. Back to the speakers…The entire time, I was extremely pleased with the way everything was going, but I kept thinking to myself…what if I did all this work and the speakers sound like CRAP!!!!. Anyways…I kept the Receiver mounted on the wall close to the Speakers to keep a shorter wire. Both left and right speakers fell about 1 inch on a stud….I thought I was gunna cry, but then I had an idea…I cut off the dog ears on the left side for the left speaker and the right side for the right speaker and screwed the speaker right into the stud….WALA…now they were even MORE secure. Side note: DOG EARS…. They work perfectly fine, but THEY need TLC. When you first get the speakers….take a screw driver and tighten them up by hand and when they get SUPER tight back them out again and then go back to tightening them again…after about 3 tries they will loosen up and will be MUCH easier to work with…people who are impatient break them because they have no common sense to think that if something it TOO Tight…I should probably loosen it up a bit before I break it. Once wired, I turned on the receiver and plugged in my phone to get some tunes going. I played some simple songs to get the speakers to go through some excursions without anything harsh so that they can break in properly. First impression???...They sucked…my worst nightmare came true…they were so bad I almost broke my phone because I squeezed it so hard….and the right one sounded like it was already blown….WTF did OSD send me? I was so pissed I turned off the receiver and took out the speaker I thought was blown, and noticed that the speaker wire behind it had LOTS of slack so that could have been hitting the cone during the excursions. I mounted it back and problem solved…..but they still sounded…BLAHHH….so I continued to paint and do my upgrades on the new house we had just built…the next day I turned them on, and again they were ok but nothing to go crazy over…and at this point it had been about 13 hours of play time, and the disappointment had set in deep…I had higher expectations for these speakers….but how could I …they were so cheap in comparison right? The third day I went an continued to do some work I put on a Sam Smith song and started to paint some more…..Sam was singing a cover of Whitney Houston’s (HOW WILL I KNOW). I must had accidentally turned the volume up A LOT and it was freking loud….luckily it was just vocals and a piano…and I had an 8” sub running super-duper low….so as I started to paint and heard Sam sing…I peeked out from the corner of the other room in total SHOCK….ARE THOSE MY SPEAKERS????...clarity, richness, mids…I mean WTF…3 days ago I was ready to throw them away…and from what I heard here….they were rivaling Def Tech’s. I was a kid in a candy store again, and I was rockin’ all day to beats that I knew would test these speakers, and they performed beautifully being pushed only with 110 per channel. The room is roughly 32 feet x 19 feet with 9foot ceilings, and I didn’t even install the ceiling speakers yet. COMPLETELY filled the room with sound…but I can tell I will need two PS88 subs just to fill the gaps of bass, but the 8” sub was enough for me. In conclusion, I’m REALLY Fuggin’ happy Thanks OSD

Great Sound Price Quality Packaging

Rock Star speaker
October 30, 2013
Do not be fooled by the reasonable price. These speakers crank. I push them with 60 Watts RMS SONOS amp and they still want to keep going. I have heard speaker twice the price and would buy these three times over. I have been running them for about 3 months now with no complaints at all. Also have had a good experience with my order and support from OSD. Don't think twice , buy them...
Pros:
Solid bass, was worried I would need a subwoofer but found they had nice tight bass.
Cons:
none
Best Uses:
In Wall, with standard insulation batting behind them to keep the sound moving forward.

I like the way these sound for music or movies. I was scared to buy them at first but glad I did! I'm not an audio expert but I have owned some good name brand speakers like klipsch, infinity, MB Quart , Rockford fosgate and JBL. I would put these up against any of them and they are a better price.

Spectacular
November 26, 2011
I replaced a set of B&W tower speakers with these in-walls, not expecting much, but wanted to declutter the living room. Seriously, these things blew the B&W's away. I have them hook up to a Velodyne subwoofer, and no kidding, the room is absolutely filled with distortion free music. Forget the price point on these. You would't do better than these paying four times the amount. Took me two hours to install (being very careful) I felt like taking the B&W badges off the front of the towers and gluing them to the grills of these in-walls. Thank you, thank you! Delivery was dead easy - arrived in week to Canada.

I absolutely love Outdoor Speaker Depot.com. I was able to install a whole house audio system with the help of the friendly staff at OSD. I have purchased all of my ceiling speakers, volume controllers, speaker brackets, indoor and outdoor speaker wire, a frog speaker, and a dual source, 8 zone speaker selector unit from Outdoor Speaker Depot. Every time I call in, the staff is always friendly and helpful no matter what type of question I have. They have excellent shipping as the order typically ships the same day and I receive it within a week of placing the order. I am extremely pleased with Outdoor Speaker Depot.com and will continue to purchase from them whenever I need new speakers or equipment for our system. Thanks a TON OSD!

I disagree the previous reviewer, for in wall speakers which donńˇ╗t have back box enclosure the MK-W850 give great bass. I installed them in my home theatre room and sound great either watching movies or listening music. Ińˇ╗m a custom installer and have been using Jamo and Speakercraft speakers before, these MK speakers definitely give them a run for the money.

September 28, 2009
Overall pleased with the sound but a bit disappointed in the bass response from the 8ţ upgrade. I think this applies to all ceiling in wall speakers. The overall sound is what I═d expect from a 6.5ţ driver, so there═s no real benefit to having a larger driver with a larger footprint in the wall. If I were to do it again I═d go with the 6.5ţ drivers & add a small sub to tackle the lows below 80hz or so. A simple 8ţ or 10ţ powered sub (NOT in-wall) would balance it nicely. Apart from the sonic improvement, the smaller satellites would be less intrusive in the wall space. Given the limitations of the speakers, the sound they do produce is excellent & it appears to be very well made with quality ingredients.
