Each zA1.1 is manufactured in the USA and carries a five-year warranty. The user manual for the zA1.1 can be found on Janszen's web site and is extremely thorough, covering all aspects of the zA1.1's technical features as well as instructions for proper placement and ongoing care.
After decades as an engineer working in fields as diverse as manufacturing, instrumentation and embedded software, the younger Janszen turned his attention to audio, with a commitment to carry on his father's work in electrostatic loudspeaker research and implementation.
It's a tall order, but Janszen, being the company that invented and brought to market the first practical electrostatics in the 1950's, has a leg up on all that. Our compact, closed-back (non-dipole) designs disprove every criticism of electrostatics we've ever heard.
Over the course of the next three decades, Janszen developed numerous electrostatic loudspeakers under his own name as well as for KLH, Acoustech/Koss and Electrostatic Research Corporation. In 2005, Arthur Janszen's son, David A. Janszen, founded Janszen Loudspeaker Ltd.
All modern Janszen Audio products extend the technology of David Janszen's father, Arthur A. Janszen, inventor of the first practical electrostatic transducer in the early 1950's. For the last 15 years, David has been at the helm, developing new designs and making them available to discerning music lovers worldwide.

Although relatively modest in stature (I'm estimating 3' tall) the Janszens projected an image that more than filled his 17x20 room. Upright bass (my personal 'litmus test' so to speak) sounded magnificent and dead on the money ."
