The US Freedom Pavilion: The Boeing Centre is a 36,000sq.ft angular edifice dominated by a five-story, steel-and-glass atrium which houses six wartime aircraft suspended in frozen flight, including a B-17 Flying Fortress. Despite the acoustical hazards posed by surfaces of glass and concrete, the CAL loudspeakers allow the museum to direct exceptional audio clarity to the audience for almost daily programmes of lectures, video screenings, and musical entertainment.
"We were originally sceptical about having decent sound in the space, largely based on prior experience in another pavilion using older technology," admits Paul Parrie, associate vice president of operations for the museum. "But we are amazed at how well the Meyer Sound CAL system works here, and we are very pleased with it."
Precise, uniform coverage of the 700-person capacity audience area is provided by two CAL 64 loudspeakers, aided by two UPJunior VariO loudspeakers for near-stage-fill. Low end for music and video playback programming is supplied by dual 600-HP subwoofers. The CAL loudspeakers are programmed with two presets: one uses dual split beams on both sides for larger audiences, while the other uses a single beam at a steeper angle for smaller audiences.
"The wall opposite the stage is five stories of solid glass, and because the room is asymmetrical, the throw is much shorter on one side than the other," notes Rob Pourciau, senior project consultant for JBA. "We needed loudspeakers that could tailor precise coverage for the space, then change coverage depending on audience size, while providing both high speech intelligibility and superb music quality. CAL is the only system that could do it all and still keep the architects happy with its unobtrusive appearance."
In addition, two Meyer Sound UM-100P stage monitors provide foldback, and a Galileo loudspeaker management system featuring one Galileo 408 processor is used for optimisation and drive. The pavilion's event audio system also includes a Yamaha LS9-32 digital mixing console, Clear-Com intercom, and eight Shure ULX wireless systems which include Beta 58 handhelds and beltpacks with Countryman lavalieres. All sound and lighting systems were designed by JBA Consulting Engineers, while New Orleans-based Soundworks handled system integration.
The US Freedom Pavilion: The Boeing Center was part of a recent $35m renovation to the museum. Voorsanger Mathes, LLC was the architect and Woodward Design + Build was the general contractor. Since its dedication, the pavilion stage has hosted a broad range of high-profile speakers, including Pulitzer Prize-winning author Rick Atkinson and former vice president Dick Cheney. Musical entertainment is often provided by the female vocal group the Victory Belles.
Dedicated in 2000, the National WWII Museum features interactive exhibits, artifacts of all sizes, and special programs that together reveal how the war was fought, how it was won, and what it means in today's world.
