The Sound of Invisibility

The ElectroMotion® Architectural Series features our award-winning compact Folded Motion® thin film transducer technology, bringing a new standard in acoustical performance to in-wall and in-ceiling applications. Designed for those seeking the world's most articulate and dynamic multi-channel home theater systems, or simply a stealthy 2-channel system, the Architectural Series speakers are voice and timbre matched with one another, as well as the rest of the MartinLogan line of ultra-premium electrostatic and Folded Motion speakers.


Folded Motion® Tweeters

Folded Motion Tweeters work by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm "squeezes" air and requires almost 90% less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lightning fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.

Installer Friendly

A robust mounting-lock system allows quick, trouble-free installation. When not in use, the constant-control mounting locks are held securely within a self-contained housing. When moved into place during installation, they couple the speaker's chassis firmly to the ceiling. And if the speaker is ever removed, the locks retract and latch themselves back in their housings.

Installers rejoice as the Folded Motion tweeter is mounted at an angle, allowing the entire speaker to rotate to aim sound precisely where you want.

Stealthy Grilles

ElectroMotion architectural speakers feature ultra-low profile, paintable micro perforated grilles with no visible bezel for near invisible integration into any wall or ceiling. A magnetic system secures grilles easily into place, reducing the risk of warping or damage during installation.

Precision-Built, Advanced-Topology Vojtko™ Crossover

Carefully hand-built using only the finest polyester capacitors and air-core coils, the crossover employs MartinLogan's proprietary Vojtko topology for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source.

Multi Application Use

The EM-R is suitable for any application in small to large rooms. Ideal for use in a multi-channel home theater as a surround speaker, in a kitchen as 2-channel stereo speaker, or in a hallway as part of a distributed audio system.

Bring HiFi to a 40' Sardine Can:)!
We travel several months of the year in our 40' RV. My wife and I are more into HiFi (Got Tubes?) sound, then into say 5.1. Our RV came with a Bose 3.2.1 that required me turning it off, after about 30 mins of listening, due to ear fatigue. (The Bose 3.2.1 is an "All in One" mix of DVD/CD/FM, Amp, and came with two satellite speakers and a powered sub.) We were upgrading the TV from tube to 4K 40" Samsung, and decided to also update the rest at the same time. >Marantz NR1501 AVR (Bought primarily due to the combo of good reviews on HiFi sound quality, and size of the unit. >Oppo BDP103 Darby (Used for Bluray/DVD/CD playback, as well as streaming of say Pandora, and also input of our loss less ripped CD and Higher Definition downloaded music. The DAC does a pretty dang good job:)!) Our RV had a deep space between the ceiling and the rooftop. So this allowed us to fit the EMR's 8" into the ceiling. As the specs show, they angle already. But due to the low space between the ceiling and the sitting area, we needed to angle them a bit more. So we took two concrete Soni Tubes, and cut them at a about a 15 degree angle, this with the tilt already built into the speaker, projected the sound to where we needed it. I mentioned in my Review Title, that this is a rolling 40' long, and 88" wide (Exterior dimension.) listening 'can'. We have about 4 1/2 feet of L/R separation. For sure not ideal:)! After installation of all the gear, we let things burn in for about 300 hours. Then sat down to listen to run the Marantz Room Correction logic, establishing two sound zones. 1) To optimize where we sit off to the side a bit, on the passenger side slide of the coach. 2) For when we're entertaining, and or cooking, centering the sound stage to about mid coach. I wanted to wait to see how the 8" handled base, before deciding if I was going to try and figure away of installing a smaller sub woofer somewhere in the coach. (Would not use the same place the Bose had been installed. As it was in the kitchen cabinet that held the sink. Muted, muffled rumbling sound, was what this install produced.) We took a 6 month trip, as I continued to dial in and adjust settings via the Marantz NR1501. On a scale of 1 - 10, the Bose 3.2.1 was, if I'm being generous, a 3.5. I'd give the overall combo of our new gear, and specifically the EMR's 8" speakers, a solid 8. Very pleased with the improvement. Very pleased with out ability to have good sounds and low levels, and to 'crank it up some' (Rated 50W, but we all know that 50W rating by one company, is the same as 10W rating by another. The NR1501 is able to easily produce two channel sound, at non distorted higher levels of volume. The 8" driver does an 'adequate' job for the base. Sure, I'd like a bit more on maybe less then 3-5% of our music - but feel it does an honest job of base and mid level support. The ribbon like tweeter, does a super job on piano/strings/vocals. I can see why for those that have limitations (Us being space, in an RV. Others getting the WAF approval:)!) of speaker presence, would be very happy to add the EMR 8" into their mix. I could easily see three of these in the front, and two in the rear, with a sub's support - getting very good results in a Home Entertainment 5.1 install. I did go demo a few Meridian, Polk, B&W and even Boston ceiling speakers. I felt that for the price, these provided the best mix of sound quality, for price expenditure. I believe they provide good value, and more important - good sound.

Finally my system is happily complete
So, I listen a lot to reviews when I purchase a product. Especially something as new as the EM-R's. But their was one big problem. These speakers are so new, no one's carrying them! I've looked on Youtube... Nothing. So I thought I would write the first review on these. Firs of all, my wife said I can have a nice system as long as she doesn't see it. Well, that kind of narrowed it down so I went with the ceiling speakers. The main use for this system is movie and TV watching in the living room. We will turn on Pandora through the Panasonic DVD player but that's about it. I just wanted true sound. 1) My knowledge: Novice. I understand a lot but not half as much as some of you. I know I want nice voice for movies and no humming. 2) My TV- Panasonic VT65 30. Definitely the best plasma on the market. Better than any of my LED's or LCDs. 3) My system: a. elite 32X Reciever-had to have it professionally set up b/c I have no idea what all those buttons, knobs and things go to. I also don't give a damn and I don't want to learn it. b. 14/2 wires going to the 5 EMR's in the room. c. 700 sub with the wireless reciever. I really had no idea where I wanted to put it. d. 5 EMR's. I even have one as the center speaker and it rocks! e. Harmony 900 controller. Don't think this matters but just thought I tell ya. f. 6 theater seats surrounding the room. I've only had the speakers for 1 week so I'm sure I'll update you as time goes by. As of 1/26/12- I had the system professionally installed and callibrated. As far as bass- It's sick. You truly get a deep bass from these speakers but the tweets are extremely clear. I watch movies all the time and I can understand everything they're saying perfectly. I feel like they're walking around me when they move on the screen! Don't have much more to say about them just yet. Pros- Bar none. They really are what they say they are. There seemed to be a lot of hype but they definitely back it up. Cons- Other than price??? I would have to say the bass seems a little to much. I'm sure I'm suppose to change something on the reciever but I'm still learning. You probably wouldn't want to hook these up yourself. You've got to move the tweet around just right for your listening experience. Pay the extra $300 and let someone else do it. Overall: I'm very pleased. My wallet is a little thinner but you just can't beat the sound quality. I was racking my brain paying this much but I'm glad I did. I would do it again now that I know you usually get what you pay for with speakers. Good luck!
