The d&b audiotechnik E4 is a lightweight 2-way passive loudspeaker using a neodymium LF driver and a coaxially mounted wide dispersion dome tweeter. It offers a wide symmetrical dispersion pattern in the horizontal and vertical plane while the cabinet may be mounted in either attitude.

The E4 is intended for mobile near field applications for speech and music reinforcement in theatres, conferences, industrial presentations, broadcast studios and as surround sound, delay and fill systems. It can be used stand-alone or supplemented by different subwoofers from the E-Series. The highly compact sealed enclosure is injection moulded with an impact resistant black paint finish. The loudspeaker cabinet is weather protected and suitable for outdoor use as standard and is also available with a Special Colour (SC) option.

Features:

  • 2-Way Compact Coaxial
  • 4″ driver with neodymium magnet
  • 75″ dome tweeter coaxially mounted passive crossover network
  • Power handling capacity (RMS/peak 10 ms) 60/400 W
  • Nominal impedance 16 Ω
  • Max SPL 115 dB

Amplifiers recommended:

The d&b audiotechnik loudspeaker range is designed exclusively for operation with d&b amplifiers. These provide power as well as comprehensive control and protection functions tailored to achieve the performance, reliability and longevity associated with the d&b System approach. 

The d&b D6, D20 and 10D amplifiers are recommended to drive the E4. The d&b D80 and 30D amplifiers can also be used with the appropriate loudspeaker configuration selected.
