Electro-Voice EVH Series brings tested reliability to Jerusalem’s Teddy Stadium

Alt
  • More than 110 EVH Series loudspeakers provide robust messaging and emergency audio
  • Tel Aviv-based D-AND-D delivers innovative solution alongside Lighton Ltd and Charmer Group
  • Mr. Harel Tabibi was in charge of the sound design

Originally built in the 1990s but renovated on multiple occasions since then, Teddy Stadium is home to four of Israel’s most loved football teams: Beitar Jerusalem, Hapoel Jerusalem, Hapoel Katamon Jerusalem and Beitar Nordia Jerusalem. The 31,733 capacity venue has also been used to stage large-scale entertainment events.

For the latest phase of the venue’s audio evolution, Tel Aviv-based professional audio distribution and production specialist D-AND-D was asked to supply a multi-function PA/VA loudspeaker system that would be capable of delivering crystal clear audio throughout the venue, whose capacity was increased to its present total with the addition of a new south side stand in 2013. The system needed to accommodate standard stadium visitor and commercial messaging, as well as communications in the event of an emergency.

D-AND-D’s Danny Ariel recalls that an extensive process of “meeting with the client, understanding their needs, and then working on CAD plans,” in cooperation with the project architect shaped the eventual loudspeaker design. Positive previous experiences with Electro-Voice products meant that the brand was always a strong contender for the Teddy Stadium installation, with Ariel praising the standard of “the Electro-Voice product design, and consistent track record of innovation, high quality sound and reliability.”

The final design features a grand total of 114 Electro-Voice EVH-1152D premium 2-way coaxial horn-loaded full-range loudspeakers. Each incorporating a 3-inch DH7N titanium/neodymium HF compression driver, rotatable constant-directivity waveguide, and pattern control maintained down to 500 Hz, the EVH-1152D speakers are specifically designed to suit inherently reverberant spaces such as stadiums.

With Lighton Ltd and Charmer Group serving as project integrator and installer, the new audio system has delivered all of the robust audio performance that Ariel has come to expect of EV. “As well as quality and reliability I look towards EV for a portfolio of solutions that can cater to all the requirements of a high-end installation,” he says. “With the Teddy Stadium project it has once again risen to meet that expectation.”

EVH 2-Way Fully Horn-Loaded Speaker Systems

EVH 2-Way Fully Horn-Loaded Speaker Systems
  • 500-Hz control provided by the large, 25-inch horn that loads the woofer—the loudspeaker’s rated coverage angle is maintained all the way down to 500 Hz.
  • Such control is especially appropriate when reverberation time (T60) exceeds 2-2.5 seconds midband, where directing more sound at the sound-absorbing audience and less at reflective room surfaces increases voice intelligibility and musical clarity. The typical 12- or 15 inch front-loaded woofer is simply not large enough to achieve 500-Hz control, with coverage angles widening below 2-3 kHz and spraying midrange sound on reflective surfaces.
  • 500-Hz control preserves sound quality at beamwidth extremes, meaning that close in listeners at the lower edge of the vertical coverage angle will have much the same frequency balance as those listening closer to the loudspeaker’s aiming axis.
