General information[contribute]

The JansZen Z-400 is an electrostatic speaker. It is part of the Z series. It was manufactured from 1960 to unknown.

James Wong (May 2003): JansZen Z-400 electrostatic speakers, 8 ohms. Each speaker has (2)5" x 5" electrostatic panels and a 10" woofer with a cloth surround and a paper cone.

JansZen Neshaminy Electrostatic Model Z-400 (circa 1960-61) bookshelf (or floor-standing) speakers with one 11 1/2" (edge-to-edge, approx. 10" cone) cast aluminum frame Woofer and two 5 3/4" square high frequency tweeter electrostatic panels in each cabinet. Both woofers have red fabric surrounds, and were originally rated to handle up to 100 watts, and of course in 1960-61, they were talking "Tube Watts". The cast aluminum frames have a very unique appearance, and I suspect that they house Alnico magnets. The cabinets measure 26" X 13 1/2" X 15" and can be used in a vertical or horizontal position, as indicated on the speaker's back panels. Each cabinet weighs about 44 lbs.

Joerg Baar provided the following information (May 2001): The Z-400 ESL-speaker. It is a hybrid-type with two ESL panels per unit. Almost the same constellation like the Z-210 B but the older types of the Janszen ESL-panels are used, so it must be an much older speaker than Z-210 B. Another difference is, that the angle in which the panels stand is inverted. So the wavefronts of the two panels cross each other. There are some pictures in the Pictures section
