Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both ESL and ElectroMotion FX2 are 2-way speakers.

ESL features a 8.6x34" curved electrostatic transducer Tweeter and 1 x 8" high-excursion paper cone Woofer. On the other hand, the ElectroMotion FX2 features a " Folded Motion AMT Tweeter and 1 x 6.5" Aluminium Woofer with a Crossover frequency at 2,300Hz.
Frequency Response
ESL has a frequency range of 42-22k Hz whereas ElectroMotion FX2 has a frequency range of 55-25k Hz. With a minimum frequency of 42Hz, the ESL can go significantly deeper on the low side and provide stronger bass compared to the ElectroMotion FX2's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
ESL is a 6 ohms speaker compared to the ElectroMotion FX2 which has a nominal impedance of 5 ohms.
These two speakers also have different sensitivity levels. ESL sensitivity is rated at 91 dB and the ElectroMotion FX2's is rated at 93 dB. This 2 dB difference makes the MartinLogan ElectroMotion FX2 a more sensitive speaker compared to MartinLogan ESL, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
ESL can handle a max power of 300 watts RMS, whereas ElectroMotion FX2 has a max power handling value of 200 watts RMS, 100 watts less than the ESL.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.

Input Type and Bi-Amping / Bi-Wiring
ESL features Spring post posts which make bi-amping or bi-wiring possible. ElectroMotion FX2 has a Binding post which doesn't feature bi-amping/bi-wiring.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare MartinLogan ESL's and MartinLogan ElectroMotion FX2's external dimensions. MartinLogan ESL has external dimensions of 1350.0 x 237.0 x 420.0mm (53-1/8 x 9-5/16 x 16-1/2inch) whereas MartinLogan ElectroMotion FX2 has external dimensions of 379.0 x 355.0 x 172.0mm (14-15/16 x 14 x 6-3/4inch).
MartinLogan ElectroMotion FX2 is 971mm shorter and 248mm less deeper than MartinLogan ESL but it is also 118mm wider.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
MartinLogan ESL needs about 63% more floor or shelf area. MartinLogan ESL is 248mm deeper, so it stands that much further out from the wall. MartinLogan ESL is 971mm taller.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the MartinLogan ESL is approximately 995.4cm2 / 154.3inch2 and base area of the MartinLogan ElectroMotion FX2 is approximately 610.6cm2 / 94.6inch2. The ESL requires 63% more surface area than the ElectroMotion FX2 which gives it a small disadvantage on placement in tight spaces.
