The Ion-Tweetered Lansche Speakers
The 69" tall, reflex-loaded speaker, shown here with English audio industry veteran Henry Dienn, who heads up Lansche-Asia, combines four 8.7" long-throw woofers and two Audio Technologies 4" midrange units with an ionic tweeter. An intense RF field heats the air in a quartz cell to the point where it becomes a plasma, and this almost massless plasma emits sound when that RF is modulated with the audio signal. The acoustic output is coupled to the world outside with a horn.
I am receiving a pair of the smaller Lansche Model No.5s in late February for a review to appear in Stereophile in the late spring.
