OUR FIRST SPEAKERS

JANSZEN ELECTROSTATIC

 

One of the hottest speakers when Alterman Audio opened for business in 1973 was the JBL L100. It featured a foam grille with many squares. JansZen was a very obscure company that copied that modern, high tech design in the early 1970's. But, behind the speaker grille, or round 3 dimentional grilles are the black square electrostatic elements shown above. An electrostaticspeaker offers the advantage of ultra low moving mass, push-pull operation with a moving force applied over the entire moving surface. We sold hundreds of pairs of electrosatic speakers in the 1970s, and early 1980s. I still use me JansZen electrostatics today. The first invoice we ever received from JansZen invoiced us with the name Brontosaurus Sound in 1972.
