JansZen Z-900 (c. 1966–1967)
Little is documented about the JansZen Z-900 beyond the company's own print advertising. What the record shows: it was introduced as JansZen's top-of-the-line console loudspeaker — "the largest, finest speaker we've ever produced after 14 years of research," in the company's words, aimed squarely at what the ads called super-perfectionists.
The Z-900 paired four JansZen electrostatic elements with two Model 350D dynamic woofers, six drivers in total. Because each driver was run well below its maximum capability, JansZen claimed "virtually immeasurable distortion from 27 to beyond 30,000 Hz." The console was offered in oiled walnut. These claims appeared in the company's advertising in HiFi/Stereo Review (May 1967, p.46) and High Fidelity (October 1966, p.125); no independent period review of the Z-900 has surfaced in the record we have, so the listening reputation it may have earned rests on thinner evidence than the ad copy suggests.
Known from the advertising:
- Configuration: 4 JansZen electrostatic elements + 2 Model 350D dynamic woofers
