Our history

Sound engineering since 1927

From a two-man radio shop in South Bend, Indiana to the world's biggest stages — nearly a century of making every voice carry.

Why it matters

Generations of hands-on knowledge, in every product

Electro-Voice is one of the few audio companies that designs all of its core components in-house — enclosures, waveguides and drivers. That philosophy runs deep: the company began in 1927 as Radio Engineers, a small service shop in South Bend, Indiana, run by Lou Burroughs and Al Kahn.

Nearly a century of listening, testing and touring later, that same in-house approach shapes everything from studio microphones to stadium arrays.

Milestones

Nearly one hundred years, in six moments.

1927 — South Bend, Indiana
Lou Burroughs and Al Kahn found Radio Engineers, the small service company that becomes Electro-Voice.
The 'electric voice'
A PA system built for Notre Dame coach Knute Rockne earns the nickname that gives the company its name.
The Buchanan Hammer
The Model 664 dynamic microphone becomes famous for surviving nail-driving demonstrations — durability as a design principle.
April 8, 1963 — an Academy Award
The 642 Cardiline shotgun microphone is honored by the Academy of Motion Picture Arts and Sciences — the first award of its kind for a microphone in 22 years.
The RE20 era
The Variable-D broadcast dynamic becomes a fixture of radio and voice-over studios worldwide, to this day.
Today — the Keenfinity family
In-house design of enclosures, waveguides and drivers continues, from battery-powered EVERSE systems to 85,000-seat stadiums.

The story, era by era

Six decades-spanning chapters, from a radio bench in Indiana to stadium bowls on five continents.

Lou Burroughs and Al Kahn open a radio service business in South Bend, Indiana. When they build a public-address system for Notre Dame football coach Knute Rockne, the system picks up a nickname — his 'electric voice' — and the young company takes it as its name: Electro-Voice.

From its home in Buchanan, Michigan, Electro-Voice builds a reputation for microphones that refuse to die. The Model 664 dynamic earns the nickname 'the Buchanan Hammer' after demonstrations that involved driving nails with it — a durability philosophy that still governs how EV road gear is engineered.

The Academy of Motion Picture Arts and Sciences honors the Electro-Voice 642 Cardiline shotgun microphone for advancing sound pickup in film, radio and television — sharply reducing noise and distance effects. It is the first award of its kind given to a microphone in 22 years.

The RE20 Variable-D dynamic becomes the voice of broadcast — a favorite of radio hosts and voice-over studios for its flat response and freedom from bass-boosting proximity effect. Decades on, it remains a first-call studio microphone.

Electro-Voice remains one of the few companies designing enclosures, waveguides and drivers entirely in-house. More than one million ZLX loudspeakers have shipped since 2013; EVERSE brings pro sound anywhere a battery can go; and installations like the 85,000-capacity Estadio Más Monumental in Buenos Aires carry the same engineering to the world's biggest crowds. Electro-Voice and Dynacord are part of the Keenfinity family of brands.

Proof

History you can hear today

The same company honored with an Academy Award in 1963 now powers stages at Glastonbury Festival, the loudspeaker upgrade at Celtic Park, and the 85,000-capacity Estadio Más Monumental in Buenos Aires — stories you can read for yourself.
