 In the United States, various of these systems are now to be found at the Miami's Adrienne Arsht Center for the Performing Arts, Ellie Caulkins Opera House in Denver, Colorado, at the Des Moines Metro Opera, the Seattle Opera, Lyric Opera of Kansas City, and in the Roy O. Disney Theatre, a part of the National Hispanic Cultural Center in Albuquerque, New Mexico.This technology, which costs about $1,000 per seat, has been added or planned for during initial construction (as was the case with Santa Fe where it was added one year after the opening of the third opera house in 1998) or during planned renovation (as with La Scala during its two-year closure period).The installations of the Met, La Scala and the Arcimboldi, the Vienna State Opera, Liceu, and the Royal Opera House were possible with the donations of the philanthropist Alberto Vilar, at the time a majority shareholder of Figaro Systems.
