High-Sensitivity, Low-Distortion Transducer Design
  • All ETX woofers use Faraday rings for better vocal reproduction
  • The woofers not only have high power handling but also feature a robust mechanical design to ensure long-term reliability
  • EV focuses on engineering transducers with linear frequency response, minimizing the need for additional equalization
Components and Testing
  • All ETX components are designed from the ground up by Electro-Voice. No off-the-shelf components are used
  • The handles, pole cups and amplifier chassis are die-cast aluminum, not plastic
  • 18mm, 13-ply birch plywood with EVCoat is used throughout the ETX product line
  • In addition to industry-standard pink noise abuse tests, all models must survive EV’s proprietary 1,000-hour torture test that uses real-world signals driven beyond full output
Processing and Control
  • System DSP presets support quick and easy setup via selections for type of use, crossover frequencies and top/sub combinations
  • Includes a DSP preset for “true cardioid” configuration
  • ETX employs the same proprietary PAL and TEMP limiters developed for Electro Voice’s concert loudspeakers
  • Boundary compensation filters are included so that an ETX loudspeaker sounds the same whether it is used as a floor monitor, on a tripod or suspended from a ceiling
  • ETX offers user-adjustable features including delay out to several hundred feet, three-band parametric equalization, polarity and multiple high-pass crossover points
  • The Class-D design of the amplifier is designed to be efficient and features blower-controlled thermal management, allowing it to work in hot environments. The fan is of a quiet design and does not turn on under normal circumstances
  • Lockout mode helps prevent casual users from changing settings
LCD Interface
Complete full-function DSP control via a single-knob interface. LCD screen for easy system set-up and monitoring: location/application EQ presets, limiter status, input level controls/meters and master volume control to ensure optimal gain structure
