MartinLogan ElectroMotion ESL Electrostatic Tower Loudspeakers Put Three-Dimensional Images, Accurate Details, and Room-Filling Soundstages on Tap: Able to Seamlessly Pair with Tube Amplifiers
MartinLogan's ElectroMotion ESL electrostatic tower loudspeaker features so much cutting-edge technology, the company's engineers consider it a mini-flagship. Just consider: Its strikingly transparent, full-sized, 34-inch tall curvilinear XStat MicroPerf panel is housed within the same type of proprietary aluminum and composite Airframe found in MartinLogan's top-of-the-line models. Such innovation enables ElectroMotion ESL to produce stunningly realistic three-dimensional images and copious low-level detail. Going a step further, the handmade electrostatic panel seamlessly blends with an eight-inch, high-excursion woofer system via a proprietary crossover network that incorporates a custom air coil, steel laminate inductors, and audiophile-grade polyester film capacitors. The forward-reaching architecture means ElectroMotion ESL delivers chest-pounding bass, nuanced high frequencies, and lightning-quick transients amidst room-filing soundstages that will bring you closer to the recorded event.
Followers of MartinLogan's history will immediately notice ElectroMotion ESL's large radiating surface and 91dB sensitivity enable it to push well beyond a number of the company's previous performance benchmarks. Indeed, you'll experience engaging sound whether you choose to use a big solid-state home theater receiver or a low-power audiophile-grade tube amplifier. And you'll never be able to put a price on the remarkable transparency and incredibly accurate detail you'll hear.
Another advantage: The dipolar design in which sound gets radiated with equal intensity from the front and back of the diaphragm. Since the outputs remain in opposite phase, sound waves rippling out toward the sides meet and cancel out, drastic reducing sidewall reflections that often distort stereo imaging. It also means ElectroMotion ESL proves far easier to position in space-challenged environments. Speaking of simple setup, five-way bi-wire binding posts and adjustable ETC spikes expand your options, making it a cinch for you to fine-tune vertical sound waves and couple the speaker with a wide range of floor surfaces.
If you're looking for a reference-class electrostatic speaker that throws convincing, three-dimensional soundstages and generates the taut, tuneful bass of a well-regarded cabinet speaker, ElectroMotion ESL should be at the top of your audition list. When you consider its real-world cost, MartinLogan's five-year warranty, and Music Direct's 100% Satisfaction Guarantee, the only question is: What are you waiting for?
"I think the EM-ESL is one of the best bargains going in an audiophile music speaker. It gives audiophiles all the things most of us seem to want (huge soundstage and dramatic presentation) and all the things we should want but sometimes neglect (like neutral tonal balance and natural sound). If stereo music is your priority, I highly recommend these."
– Brent Butterworth, Sound & Vision
"[The] MartinLogan ElectroMotion loudspeakers are not only an incredible value but an incredible loudspeaker system. I've encountered no speaker at or even a few ticks above the ElectroMotion's asking price that possess the same transparency, articulation, speed and natural tone."
– Andrew Robinson, Home Theater Review
" [The ElectroMotion ESL] has an open, crisp sound that's transparent and well detailed.... The open panel electrostatic sound that's available at this price level really has to be experienced."
– Martin Colloms, HiFi Critic
