Electrostatic speakers have always had their own niche on the outskirts of a more conventional “box speaker” world, presumably a bit too exotic to fit into the average Joe's system. So when we recently auditioned the MartinLogan ElectroMotion® ESL speakers in our cavernous product training room, we were not only impressed by their dramatic sound, but surprised by how effortlessly they played with some of our more affordable audio gear, including a mid-priced receiver. Our takeaway: you don't need a rack full of uber-expensive components or a fancy, dedicated listening room to enjoy fantastic sound with these speakers.
Unlike speakers that use domes and cones to reproduce treble and midrange, the EM-ESL features an ultra-thin polymer film, or diaphragm, suspended between two electrically charged, perforated steel plates. The diaphragm's ultra-low mass allows it to move very efficiently back and forth between the plates thousands of times a second in response to the music signal creating enticingly transparent, low-distortion sound with a lifelike sense of immediacy. The panel is visually transparent, too, so it makes an unforgettable impression when seen in person.
Controlling a speaker's sound dispersion in a room is crucial to creating realistic sound. MartinLogan's signature 30º curved electrostatic panels allow for ideal dispersion in your home listening environment and minimize reflected sound off of the side walls that can muddy detail and stereo imaging. This design helps take the room out of the sonic equation.
Even the best crossovers can add distortions that negatively impact sound quality. The EM-ESL's hybrid design uses its electrostatic panel to operate all the way from the highest audible frequencies down through the crucial midrange (where our ears are most sensitive) to 500 Hz without a crossover for the purest possible music reproduction. A high-excursion 8" woofer takes over from there, seamlessly blending in to provide taut, accurate bass that rounds out the speaker's low-end end response.
We first heard the EM-ESLs in the Crutchfield Labs, where they looked and sounded like no other speakers to ever visit our listening room. Their tall sleek panels yielded exceptional levels of detail and clarity, with a huge soundstage that extended not only from wall-to-wall but from floor-to-ceiling, as well. The effect was intoxicating, almost as if the musicians were sitting right there in the room.
Sure, floor-standing tower speakers buck the industry trend toward smaller, visually inconspicuous speakers, but they're hard to beat if great sound is your primary goal. Tower speakers produce powerful sound with excellent bass, making them a great choice for serious music lovers and for folks who want high-impact home theater.
I'm very happy with my choice. Almost done with the 72 hour break in. Just starting to turn up the volume. As you increase the volume the sound field fills the room and suddenly they come alive and your family room is now a concert hall. Still tweaking the placement, only 2' from front wall and like the other reviewer can't move them too far forward. The clarity is amazing. The biggest surprise is the variety in the quality of my music library. Will need to delete some of music on my computer and down load again in higher quality. My ESL are part of my home theater, now movies are at a whole new level..
Pros: Falling in love with music again, the details you never heard before.
Cons: Non so far
Not completely satisfied with my existing tower speakers for two channel listening, I called Crutchfield for a recommendation on an upgrade. After a good deal of time on the phone explaining my likes and dislikes, my space, and my budget, we decided the MartinLogan Electromotion ESLs might be a good fit. Now, after a day of listening to them, I couldn't be more pleased. The clarity and detail are amazing and the soundstage is beautiful. Closing your eyes and listening to live performances transports you right into the audience. I am also hearing new things in my favorite recordings. These speakers are easily powered by my Marantz MM7025. Bass is decent (the hybrid design is definitely nice), but I did add a MartinLogan Dynamo 500 and would definitely recommend a sub.
Pros: Great sound, stylish looks, and easier on the budget compared to more traditional speakers delivering the same quality of sound.
Cons: Not really a con, but these speakers will reveal both the good AND the bad hiding in your recordings. Sweet spot seems narrower than conventional speakers. Finally, they do need a bit more room to breath than my previous speakers, but if you have the space that's not an issue.
I bought/auditioned 4 different speaker sets before sticking with the ML ESL home theater (including these ESL's). I was hesitant at first because of things I have heard about electrostats. I heard that if they're not positioned perfectly they don't sound good. That's not true. I found their perfect placement and it's about 5 ft from my front wall. The wife disapproved, and the wife won. However, now that they're only just under 2 ft from the wall, they still sound better than any speaker that I've had. I heard that they're hard to drive. That is not true, I borrowed my friends cheap sony receiver and they played plenty loud and still sounded great. That being said, I have them running from a separate pre/pro and amp, and they sound even better when driven properly. They said they're not durable. I dropped them (oops), they still work, however I haven't had them long, so I can't speak to their long term reliability. I have no doubts that they will last as long as any other speaker. Last thing I've heard is that they're not loud enough and don't sound good with some music. As far as being loud, unless you're trying to blow out your ears, they're loud enough. They can play loud enough to make my ears ring, and I have a large listening area (25x20x11ft). As far as music, all my music sounds good on them, however my choice of music may change only because these speakers really do bring out everything (the good and bad) in the recording. These speakers are amazing!
Pros: Look and Sound amazing. Until you hear electrostats, you don't know what they're missing. Try them out, you won't regret it.
Cons: Flimsy feeling speaker wire terminals.

Hybrid Electrostatic Speaker: The MartinLogan ElectroMotion ESL is a hybrid electrostatic loudspeaker that features a XStat CLS electrostatic transducer panel, an optimized Vojtko crossover, and a passive 8" woofer. Electrostatic panels are perfect for reproducing high, midrange, and midbass frequencies. However, both the size and the power requirements of deep bass frequencies are best served by traditional cone woofers. A phase and amplitude optimized Vojtko crossover (500Hz) ensures a seamless transition between the two sound reproduction philosophies. As a result, this speaker offers the best performance for high, mid, and low frequencies.
XStat CLS Transducer: The MartinLogan ElectroMotion ESL features a 8.6" (w) x 34" (h) XStat CLS Transducer. This new XStat transducer builds upon the legacy of MartinLogan's electrostatic heritage with the incorporation of a myriad of technology and design innovations including CLS, MicroPerf, Generation 2 Diaphragms, ClearSpars, Vacuum Bonding, and AirFrame technology. Through rigorous testing, this curvilinear electrostatic panel has proven itself to be one of the most durable and reliable transducers available today. Fabricated from a custom tool punched high-grade steel, the patented panel is then coated with a special polymer that is applied via a proprietary electrostatic bonding process. This panel assembly houses a membrane just 0.0005" thick. Ruggedly constructed and insulated, the panel is rated to easily handle 20 to 400 watts of power.
Controlled Dispersion Sound Radiation: A key attribute of the ElectroMotion ESL is its naturally dipolar radiation pattern. A true dipole, the EM-ESL radiates sound with equal intensity from the front and back of its diaphragm, but the outputs are in opposite phase. As a result, sound waves rippling out toward the sides meet at the speaker's edge and cancel. That and the relatively large size of the ElectroMotion ESL's electrostatic panel cause output at the sides to be very low relative to that of a conventional loudspeaker, which in turn minimizes side-wall reflections that tend to muddle sonic detail and stereo imaging. While the reduction in output to the sides contributes to the astonishing clarity, the energy reflected off the wall behind the speaker opens up and deepens the sound.
Full-Range Operation: Another significant advantage of MartinLogan's exclusive electrostatic transducer technology is that no crossover networks are used above 500Hz, because they are not needed. The ElectroMotion ESL consists of a single, seamless electrostatic membrane reproducing all frequencies above 500Hz simultaneously. This eliminates the crossover phase aberrations that are associated with traditional tweeter, midrange, and woofer systems. The result is a dramatic improvement in imaging and staging performance.
Passive 8" Woofer w/ Ported Cabinet: A precise 8" high-excursion, perfectly balanced, audiophile grade, doped-fiber cone woofer has been custom designed exclusively for The EM-ESL by MartinLogan's in-house engineering team. This woofer precisely optimizes cone suspension and magnetic flux field to produce high levels of bass output and simultaneous precise midrange. The custom woofer's rigid light-weight diaphragm eliminates cone flexure and maximizes response time to achieve remarkably low-distortion. The 8" woofer is housed in a non-resonant asymmetrical cabinet with a down-firing bass port for additional bass extension.
Note: When you first begin to play the ElectroMotion ESL speaker, it will sound a bit bass shy. This is due to the high-quality, long-life components used in the passive woofer. The custom-made woofer requires approximately 72 hours of break-in at 90 dB (moderate listening levels) before any critical listening. The break-in requirements of the crossover components (and, to a lesser degree, the stator) are equivalent.
Proprietary Vojtko Filtering: To seamlessly blend audio output from the high- and mid-frequency electrostatic panel to the low-frequency woofer the ElectroMotion ESL features a proprietary Vojtko topology filter utilizing custom air core coil and low DCR steel laminate inductors, polyester film capacitors in series, and low DF electrolytic capacitors in parallel.
Spring-Post Connectors: The ElectroMotion ESL features two spring-post connectors to attach your speaker wire. The spring-posts will accept bare wire (16- to 10-gauge), pin-connectors, and banana plugs (single only).
Low-Voltage DC Power Supply: The ElectroMotion ESL speaker uses an external low-voltage power supply to energize its electrostatic panel. The included power supply firmly inserts into the "DC Power In" receptacle on the rear-panel of the speaker and then to an AC wall outlet. The ElectroMotion ESL speaker features a signal sensing circuit which will switch the ElectroMotion ESL off after a few minutes of no music signal, and requires less than two seconds to recharge the panels when a music signal is present.
Applications: The MartinLogan ElectroMotion ESL floor-standing speakers can be used as stereo speakers or home theater front/surround speakers. The ElectroMotion ESL speakers are ideal for medium and small rooms.
Placement: The ElectroMotion ESL speaker should be placed approximately 2' to 3' from the front wall (the wall in front of the listening position) and about 2' from the side walls. Your sitting distance should be further than the distance between the ElectroMotion ESL speakers themselves. This will allow you to attain good center imaging and stage width. Generally, it is found that the ideal listening position is with the speakers slightly toed-in so that you are listening to the inner third of the curved transducer section.
Note: The front wall surface ideally should be one long wall without any doors, windows, or other openings. If you have openings, the reflection and bass characteristics from each channel can be different.
Interchangeable Feet: The MartinLogan Theos floor-standing loudspeaker includes four pre-installed rubber feet for tile and hardwood floors. You can remove the rubber tip from the pre-installed feet to reveal four metal spiked feet for carpeted flooring. The feet are threaded into the base of the speaker and can be adjusted to non-level surfaces.
Placement is indeed important, but not terribly difficult and can even be kind of fun as you discover the capabilities of these incredible speakers. Take the time to position the speakers in all the dimensions described in the manual: distance from side wall, distance from back wall, "toe-in" angle (using the flashlight reflection against the front panel, and finally the vertical angle (which does indeed make a difference). Also, I have two "modes of listening: one mode is for non-critical everyday stuff where I don't mind if my amplifier is doing the digital processing and tonal settings; the other mode is critical listening where I want the source to be as pure as possible and don't want any processing from my amplifier. Make sure your source audio is tope quality - you will hear the difference between lossy compressed 128 bit audio and lossless 256 bit audio. I eventually bought a Cambridge Audio DAC Magic Plus digital to audio converter which completely bypasses both the DAC in my Mac and the DAC in my amplifier. I hear things in my music collection that are truly astounding. On the other hand, crappy recordings will sound just that - crappy! So things you tolerated before may become really annoying now. Overall, these are great speakers - just take the time to set them up. [ JUSTIN Jan 22, 2014 ]
It really isn't that difficult to set them up. Any speaker requires proper set up to sound its best. If you use the included guide as a start, then allow the speakers to break in their full period, fine tuning should be pretty easy. It took me about 15 minutes to place them by the guide and then a couple minor tweaks over a couple days after they broke in to get them to their best. [ GREGORY Jan 17, 2014 ]
I didn't find it difficult at all to set them up. I think that the confusion that I've seen around this issue is related to the "correct toe-in" and spacing issue...such as is addressed in some of the YouTube videos from MartinLogan. But for my taste they sounded great out of the box. If you are looking for the "ideal sweet spot", they you can do some experimentation, but frankly these speakers have a 30 degree curve built in, so I found that the sound radiates to all parts of the room very well. 2 things I would recommend...they do have a "break-in" period of about 80-100 hours of listening, after which time you'll notice them sounding SO much better, (not that they don't sound awesome out of the box....they just get even better). 2nd, I would definitely recommend a subwoofer to back these up. That being said, these are the most amazing sounding speakers I've ever heard. Listening to music is an incredible experience now, and this is coming from a life-long audiophile. Buy these....you won't regret it. [ Douglas Jan 16, 2014 ]
I found placement much easier than some reports have suggested. I have them only about three feet from the wall, toed in slightly, and they sound great. I expected to have more problems with them, given that they are dipole speakers, but they are much more forgiving than online reports might lead you to believe. MartinLogan's staff are very helpful and I am sure you could always work with them if you need assistance. [ ZACHARY Jan 16, 2014 ]
I'm currently using Parasound 2250. Originally I was using Onkio NR929 receiver. It's suggested on different forums that they need more power and a bigger power reserve for the impedance dips. Inserting the Parasound amp really made a big difference. My next upgrade will be a class AB amp. My system is enclosed In a wall unit and the heat from a Class A would be too much. Originally I had home theater setup, but now with the Theos I'm doing more 2 channel listening. No matter what you choose you'll enjoy the journey. [ CALVIN L. Jan 02, 2016 ]
i own Martin Logan Theos. They love lots of clean power. I would guess the same for the ESL's. The Sony TA-A1ES is a class A amplifier and I have no experience with class A. I'll guess it's a great setup for low to moderate listening levels. [ CALVIN L. Jan 01, 2016 ]
