Martin Logan ElectroMotion ESL

Industry professional selling personal Martin Logan ElectroMotion ESL speakers due to updating to higher model. Just over a year old with all packing materials and manuals as well as two power cables.  They were in a smoke free home and in perfect condition. They will be listed on other sites as well as locally and listing will be ended if sold through other means.  Local Pickup preferred but freight at your own expense as it is best to ship them on a pallet not just in the boxes. 

NOTE: From Martin Logan's Site "Priced at $2,499.95 per pair, the ElectroMotion ESL (EM-ESL)
represents a brave new direction for electrostatic loudspeaker design.
Featuring a full-sized 34-inch tall curvilinear XStat™ electrostatic
transducer the new ESL performs more like a mini-flagship than an entry
level audiophile speaker.
Long time MartinLogan enthusiasts are sure to describe ElectroMotion ESL
as the second-coming of the legendary Aerius electrostatic speaker
which debuted in 1992 and went on to sell in record numbers. The new
ESL, however, boasts 40 percent more radiating surface, a superbly
integrated and authoritative bass performance, and a sensitivity rated
at 91dB. In addition, the ESL is capable of being effortlessly powered
by both receivers and high-end amplifiers alike.

ElectroMotion ESL's XStat electrostatic MicroPerf panel is
housed within a radical aluminum and composite AirFrame™ similar to
those found on MartinLogan's flagship products. AirFrame technology
rigidifies the electrostatic panel without obstructing playable surface
area or interfering with ambience enriching dipole sound radiation. At
the same time, an AirFrame provides electrical and acoustical isolation,
minimizing intermodulated distortion caused by vibration and resonance
while enhancing imaging, low-level sonic detail, accuracy, and
efficiency.
MicroPerf design optimizes the individual holes of The EM-ESL's
electrostatic panel. MicroPerf design substantially increases diaphragm
radiating area, compared to early generations—without compromising
structural integrity. The resulting increase in output capability and
efficiency allows The EM-ESL's panel to enjoy a substantial leap in bandwidth and dynamics without growing larger. For example, The EM-ESL's
XStat electrostatic panel features 129 square inches of sound radiating
surface on both the front and back and a sensitivity of 91dB into 6
Ohms. The Aerius, well received its day, only had 93 square inches and a
sensitivity of 89dB into 4 Ohms.

A unique XStat™ transducer was developed for the ElectroMotion ESL
to reduce the gauge thickness of the electrostatic panel's steel
stators. The reduced gauge does not alter the performance
characteristics of the panel. However, as a natural byproduct of tighter
build tolerances, it does increase the visual transparency of the
panel. The EM-ESL's new XStat panel is so visually transparent it nearly vanishes when you're sitting and listening.

CLS™ XStat™ Transducer

One of MartinLogan's original breakthroughs, CLS™ (Curvilinear Line
Source) technology, has been an essential ingredient of every
electrostatic loudspeaker we've produced—and the ElectroMotion ESL
is no exception. Proprietary manufacturing methods enable construction
of electrostatic panels as cylindrical sections. Their gentle horizontal
curvature solves the problem of obtaining good high-frequency
dispersion from a large radiating surface without compromising overall
sound quality or reliability.

Controlled Dispersion Sound Radiation

Another 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 for which electrostats are revered, the energy reflected off the
wall behind the speaker opens up and deepens the sound.

Superb Bass Integration

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.

A precise 8-inch high-excursion, perfectly balanced, audiophile grade,
doped fiber cone woofer was 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 minimizes
response time to achieve remarkably low-distortion approaching that of
MartinLogan's award-winning electrostatic panel design.

Easy Connections, Solid Adjustable Footing

Convenient push-style speaker terminals and curved inserts help guide
speaker wire effortlessly into place. The rubber end caps on the
terminal are also removable for the use of banana plugs instead of bare
wire. The EM-ESL is supplied with sturdy, 3/8-16 ETC™ spikes,
which can be used to fine tune vertical wave launch, enhance stability
on thick carpets, and create tighter coupling between speaker and floor
to provide a tighter and detailed bass performance. Each spike is
conveniently covered by removable rubber end caps if you prefer not to
use spikes."
