MartinLogan ElectroMotion ESL X floorstanding loudspeaker

MartinLogan ElectroMotion ESL X

I’d rate the sensitivity at around 89dB, but the bass end (sub-500Hz) is very uneven. However, don’t let the uneven bass end put you off, as the smooth (albeit somewhat forward) mid-band dominates the bass end. This speaker works particularly well at modest levels, due in part at least to the forwardness that seems to emphasise the voice band.

Like most electrostatic loudspeakers in a dynamic loudspeaker world, this is a difficult speaker to summarise. In part it places an emphasis on the listener’s reaction to the sound, but if you find yourself swayed by an unparalleled lack of perceived mid-band and high-frequency distortion, there might be no going back. The MartinLogan Electromotion ESL X is an exceptional performer for the price, especially for anybody who likes to listen at modest levels (the larger models are more accommodating for the unrepentant headbanger). What the speaker offers is something that both sounds – and looks – distinctly and genuinely ‘different’ from the norm, and for many that’s a good thing. I reckon that such an observation alone should be enough to put it onto many listeners’ short-lists.
