We use a novel design of electrostatic driver panels for the upper bass through the treble -- around 200 Hz - 30 kHz. All frequencies where accuracy matters most are thus produced by the most phase-accurate, low distortion, and transient-accurate drivers made.
All ESL's use nearly weightless membranes for moving the air. It's simple and linear. Ours, however, also have high damping. As with a shock absorber, all motion is fully controlled, reacting precisely to the musical signal, never bouncing along on its own after a sound is supposed to end. This eliminates the resonant coloration affecting see-though ESL's.
By using fully enclosed cabinets, unlike most planars, JansZens put sound out only to the front. This makes setup as easy as with regular speakers, and eliminates the comb filtering that colors the sound from large area dipoles.
JansZen line sources create a wide sweet spot and avoid beaming and exaggerated response lobes without curved membranes or facets. They also have very restricted vertical dispersion, minimizing the impact of the floor and ceiling on the response.
And the stereo image and tonal uniformity are exceptionally strong throughout the room, even away from the area directly ahead of the speakers, due to the drivers' well integrated, cylindrical sound fields.
These are like no other speaker, and no other electrostatic.
