The Football Stadium of Lorient in
France recently got an Adamson
Metrix loudspeaker system installed.
France (January 7, 2009)–Adamson Metrix W enclosures were recently used as part of a permanent system installation in the Football Stadium of Lorient by Audiolite. Lorient is located in Rennes, Brittany on the Atlantic Ocean.
The 31,127-seat stadium, completed in 2004, uses its new new sound system for speeches, sports and the occasional music festival. The installation design was carried out jointly by Audiolite and DV2. Audiolite is the Western France dealer for DV2 – Adamson’s Distributors for France.
On the site, project supervisor Franck Fily, sound system designer Sylvain Turpin, rigging expert Lionel Gillet and cable manufacturer Jord Mallejac placed three clusters of six Adamson Metrix Ws in the North bleachers and four clusters of six Adamson Metrix Ws in the Presidential bleachers.
With the stadium residing near the Altantic Ocean, many steps were taken to guarantee the system’s longevity, despite the incessant salty ocean air. First, was waterproofing it against humidity using a special paint for the birch enclosure. It was then varnished inside out with a special varnish covering every inch of the wooden surface. The usual Speakon connectors were removed and replaced with strain reliefs-directly to the box. The speaker components were tropicalized, further water-proofing parts such as the already weather resilient Kevlar cones. All rigging hardware including frames and pins were galvanized. The grill was constructed from aluminum, instead of the usual steel.
“Due to difficult rigging point options, a vertical area of 90 degrees had to be covered with each cluster, making the Adamson Metrix W’s 15 degree vertical coverage essential” comments DV2 technical director Didier DalFitto. Turpin adds: “We needed to find a system that would fix the problems with the old speaker system, which had bad coverage and frequency response, as well as insufficient SPL for this specific venue. The Adamson ND-8LM 16 Ohm drivers made us gain some savings due to less cabling and amplifying. We put 6 Metrix W LF & HF’s on two channels of a Lab.gruppen C68:4”
