Electro-Voice electroacoustic engineering milestones and heritage since 1927

American audio pioneer Electro-Voice traces its operational origins to September 1927 when engineering founders Al Kahn and Lou Burroughs established a specialized sound service shop in South Bend, Indiana.

Confronting sharp economic shifts, the partners pivoted toward developing proprietary microphones and horn systems, assembling a high-output public address solution for coach Knute Rockne, who coined the term electric voice.

Across following decades the enterprise introduced fundamental acoustic breakthroughs, including noise-rejecting military communications gear, the proximity-neutral Variable-D microphone principle, and an Academy Award for the 642 Cardiline shotgun microphone.

Joining Bosch Communications Systems, the brand synthesized time-honored acoustic craftsmanship with rigorous European automated manufacturing and inspection standards.

Portable performance systems across ZLX G2 and ELX200: topology and SST wave guides

The second-generation ZLX and ELX200 portable loudspeaker series serve as an international benchmark for touring performers, hospitality venues, and mobile AV rental firms.

Rugged polymer enclosures with structural internal ribbing suppress spurious mechanical vibrations under maximum sound pressure, while the horn flare section ensures uniform dispersion throughout audience seating.

Proprietary SST (Signal Synchronized Transducers) technology physically aligns the high-frequency compression driver forward relative to the woofer voice coil, securing coherent phase summing and transient accuracy.

Onboard Class-D power amplification managed through QuickSmartDSP processing monitors input dynamics, preventing clipping while sustaining balanced tonal output across challenging room acoustics.

Modular column speaker arrays across EVOLVE series: dispersion and compact footprint

Modular sound reinforcement packages within the EVOLVE 30M, EVOLVE 50, and 50M families streamline deployment across corporate halls, auditorium presentations, and live performance venues.

The physical assembly unifies an active wooden subwoofer enclosure with an interlocking aluminum vertical column housing multiple neodymium full-range drivers aimed via precision-calculated internal guides.

An ultra-wide 120-degree horizontal radiation angle coupled with a 40-degree vertical pattern provides articulate vocal reproduction and flat acoustic energy from the front row to rear boundaries.

Integrated Dynacord multi-channel digital mixers featuring wireless parameter editing permit quick optimization of channel routing, graphic equalization, and studio-grade reverberation effects.

Installed sound transducers across EVID and EVF: weather resistance and 70/100 V lines

For permanent architectural sound deployment in shopping centers, hospitality environments, arenas, and sports stadiums, Electro-Voice manufactures dedicated EVID and EVF product families.

Rugged UV-resistant composite housings achieve IP54 environmental protection ratings, while perforated steel grilles backed by hydrophobic foam shield acoustic diaphragms from dust, humidity, and atmospheric pollutants.

Installed variants incorporate internal wideband matching transformers enabling multi-speaker interconnection along high-impedance 70 V and 100 V distributed infrastructure with minimal line losses over long cabling distances.

Patented Strong-Arm-Mount wall brackets provide multi-axis angular aiming for targeting acoustic energy directly toward designated listener regions.

Compression high-frequency drivers and diaphragms: dome geometry and motor efficiency

High-frequency compression transducers across DH1K, DH2010A, DH3, and ND2 series constitute critical electroacoustic assemblies subject to significant thermal and dynamic mechanical stresses.

Ultra-thin titanium foil coupled with high-temperature polymer suspensions extends frequency reproduction up to 20 kHz while maintaining exceptionally low total harmonic distortion under elevated output levels.

For ongoing maintenance of touring loudspeakers, factory-matched replacement diaphragm kits feature precision edge-wound aluminum voice coils supported on Kapton formers.

Magnetic gaps are treated with specialized damping ferrofluid, which expedites thermal dissipation away from the voice coil toward the magnetic return structure, enhancing long-term reliability.

Low-frequency transducers across EVS and DL lines: cone stiffness and thermal cooling

Heavy-duty woofers with frame diameters of 12, 15, and 18 inches across EVS-12M, EVS-15L, and DL12BFH lineups are purpose-built for sustained performance inside concert monitors and vented subwoofers.

Structural precision-molded aluminum frames preserve alignment during heavy transit and conduct heat away from the magnetic circuit during extended operational cycles.

Long-fiber pulp cones treated with proprietary moisture-resistant compounds deliver structural stiffness with low moving mass, preventing nonlinear cone breakup at extreme acoustic levels.

Large vented pole pieces and perimeter airflow ports continuously flush voice coil windings, curbing dynamic power compression and preserving punchy, articulate low-frequency energy.
