The d&b audiotechnik E-Series expands with lightweight two-way passive E4 and E5 loudspeakers. They use a 4" and 5" LF driver and a coaxially-mounted wide dispersion dome tweeter. Both are mounted in highly compact enclosures and offer wide symmetrical dispersion patterns in the horizontal and vertical plane, and the cabinets may be mounted in either attitude.
They have built-in passive crossover networks with a frequency response extending from 130 to 20 kHz (E4) and 85 Hz to 20 kHz (E5). They weigh in at 1.1 kg (2.4 lb) and 2.2 kg (4.8 lb) and produce a maximum dB SPL of 115 and 117 respectively.
In terms of size, they fit below the recently-launched E6 (the successor for the E3). The E4 will be available from November 2011. The E5 (a new design for the E0) is scheduled for release in January 2012.
The enclosures are injection-molded and coated with an impact resistant black paint finish. A rigid metal grill protects the front of the loudspeakers. An M10 threaded insert is incorporated into the rear panel to accept the Ball joint adapter, two NL4 connectors and a 2-pole push terminal.
The loudspeakers are weather protected and suitable for temporary outdoor use as standard, and as with all other E-Series cabinets are available to order with a special color option. They can be powered by either the d&b D6 or D12 amplifiers and up to four cabinets may be driven by each channel of either amplifier.
Firmware and software updates including the E4 are available for download under the relevant sections within Support/Downloads at www.dbaudio.com. These provide configurations for all current d&b amplifiers and the latest version of R1 Remote control software. Firmware and software updates to include the E5 will be available in January 2012.
The E4 and E5 loudspeakers are specifically intended for mobile near field applications for speech and music reinforcement in theatres, conferences, industrial presentations and broadcast studios and as surround sound, delay and fill systems. Both can be used stand-alone or supplemented by different subwoofers from the E-Series.
