Electro-Voice

Electro-Voice is an American manufacturer of professional audio equipment including microphones, loudspeakers, and amplifiers with origins in the 1920s. The company developed products for broadcast, recording, live sound, and public address used by performers, studios, venues, and government agencies across North America, Europe, and Asia. Electro-Voice grew through patents, product lines, and corporate acquisitions, influencing designs adopted by theatres, stadiums, and recording studios.

History

Electro-Voice was founded in 1927 by Edwin S. Pridham and Lou Burroughs in Lafayette, Indiana, contemporaneous with companies such as RCA, Western Electric, Bell Labs, Bose Corporation, and Shure. Early development coincided with the expansion of Radio Corporation of America, the rise of NBC, and the growth of broadcast studios in New York City and Chicago. In the 1930s and 1940s the firm expanded product lines during the era of World War II when many audio firms supplied equipment to the United States Armed Forces and collaborated with contractors like Grumman and Lockheed. Postwar growth paralleled the proliferation of recording studios such as Capitol Records and Abbey Road Studios, and Electro-Voice introduced elements used by artists on labels such as Columbia Records and Decca Records. During the 1960s and 1970s the company competed with manufacturers like Sennheiser, AKG, JBL, and Yamaha Corporation while serving venues including Madison Square Garden and Sydney Opera House. Later corporate changes involved mergers and ownership transitions similar to patterns seen at Harman International Industries, Bose Corporation, and Bosch. The brand’s later decades saw products adopted in touring operations managed by companies such as Clear Channel Communications and production firms like Live Nation and AEG Live.

Products

Electro-Voice product lines have included dynamic microphones, condenser microphones, ribbon microphones, loudspeaker drivers, passive speakers, powered speakers, subwoofers, mixing consoles, wireless microphone systems, and installation amplifiers used in settings from houses of worship to stadiums. Notable microphone models have been used alongside gear from Neumann, Shure, Sennheiser, AKG, and Royer Labs in studios including Sun Studio and Muscle Shoals Sound Studio. Loudspeakers and active systems have been specified with amplifiers from Crown International and processors from dbx and BSS Audio in touring rigs for artists represented by Live Nation, U2, Madonna, and Taylor Swift. Installation products have been deployed in theatres such as Royal Albert Hall and arenas like Wembley Stadium, and in broadcast facilities including BBC Broadcasting House and CBS Television City.

Technology and Innovations

Electro-Voice has developed patented elements in transducer design, voice-coil construction, magnet systems, and preamplifier circuitry, paralleling innovations from Bell Labs, RCA, and Philips. The company introduced ruggedized dynamic elements used in live touring by production companies such as McCune Sound Service and integrated HF compression techniques comparable to designs from JBL and Altec Lansing. In wireless systems and capsule design, Electro-Voice advances have been considered alongside developments from Sennheiser and Shure. Their work in horn-loaded speaker geometry and dispersion control informed installation standards in venues managed by SMG and acoustical consulting firms like Arup and AECOM. Contributions to microphone polar pattern stability and noise floor reduction have been relevant to recording engineers at studios operated by producers such as Rick Rubin, George Martin, and Quincy Jones.

Notable Installations and Use

Electro-Voice products have been installed in performance spaces, broadcast facilities, houses of worship, and government locations. Examples encompass use in venues such as Carnegie Hall, Radio City Music Hall, Sydney Opera House, and sports arenas including Madison Square Garden and Staples Center. Broadcast adoption has included facilities operated by BBC, NBCUniversal, CBS, and ABC, while recording applications have appeared at Abbey Road Studios, Capitol Studios, and Sun Studio. Touring sound systems employed by acts managed by Live Nation, AEG Presents, and production firms like PRG have used Electro-Voice loudspeakers and microphones. Public address implementations span airports such as Heathrow Airport, transit systems administered by agencies like Metropolitan Transportation Authority (New York), and civic sites in municipalities comparable to City of Los Angeles.

Corporate Structure and Ownership

Over its history the company experienced ownership and structural changes similar to patterns at firms like Harman International Industries, Bose Corporation, Yamaha Corporation, and Sennheiser. Corporate governance included executive leadership, engineering divisions, sales and distribution channels, and partnerships with international distributors in regions including Europe, Asia, and Latin America. The company’s parentage and corporate transactions paralleled consolidations seen in the audio industry involving conglomerates such as Bosch, WH Smith, and private equity firms, while business units interfaced with standards bodies like AES and regulatory agencies such as Federal Communications Commission.
