The KLH Nine was the first truly full range electrostatic speaker. Even fairly recently, it was declared one of the 12 most significant speakers of all time and has been written about repeatedly. Production began in late 1959 and continued for nearly twenty years. The list price was initially about $2,000/pair, which translates to about $20,000 in 2023 dollars.

The KLH Nine is the superb sounding and history making, full-range electrostatic loudspeaker that Arthur A. Janszen (AAJ) created at JansZen Laboratory and put into field tests in 1957. This design was then taken on by KLH and put into production at the end of the 1950's, with AAJ as V.P. Engineering.
