Alvin Gold tunes in to Martin Logan’s latest affordable electrostatic hybrid loudspeaker, the ElectroMotion...


There are only two really important brands of electrostatic loudspeakers, and Martin Logan is the other one. Many years ago, when Martin Logan was a fledgling, the company was hamstrung by talented but sometimes flakey drive units, and by hybrid moving coil bass drivers that didn’t match the aspirations of the electrostatic mid and treble drivers. In the end, the solution was not to get rid of the moving coil bass drivers, but simply to do them better. In fact MartinLogan has been on a trajectory of increasing refinement with all their drivers, and also with the physical structure of their speakers which look and work better than ever.

   The first model in recent times that really set a high standard was the Summit, which also set a new standard for affordability and stereo imagery at the time. The more expensive models now integrate much better than before, and handle the crossover region between bass and mid/top with greater aplomb. Over the last few years new models have been introduced at progressively lower prices levels, and the ElectoMotion, reviewed here, which is a completely new model, is a remarkably fine newcomer that takes the formula one step further. It is by any standards an unusually cost-effective design, and it is also beautifully packaged and presented.


Like earlier models in the MartinLogan range, it is tall, slender, and sports a slimline electrostatic panel that tilts gently backwards. The panel (which covers everything north of 500Hz) takes up the top two thirds of the speaker, and is radiused to control imagery. In common with all MartinLogans in recent times, the bass section houses an 8 inch bass driver mounted in a heavy bottom vented section of the enclosure. As with all electrostatics, the electrostatic panel needs a polarising voltage and it is supplied by a high voltage circuit that shares space with the bass driver and crossover.
