History and Technical Development
On September 1, 1927 Lou Burroughs and Al Kahn founded a small radio shop in South Bend (Indiana). As an effect of the Great Depression, the two were insolvent and had $ 5,000 debt. They decided to relocate their business to audio products. Electro- Voice first product was a public- address system, which was delivered to the football coach Knute Rockne.

In 1986 the company introduced the Manifold technology for concert halls. Manifold allows the feeding of various speaker driver in a horn. In 1997, the ring -mode decoupling approach was presented.
