The Grande Utopias are not only loudspeakers that have had a great impact on their generation. It's also the most accomplished concept of "The Spirit of Sound", the ultimate reference. After the W cones and the pure Beryllium tweeter of the previous models that had marked a technological advance, the Grande Utopia EM adopts an Electro-Magnet woofer (EM) with a force that cannot be compared to classical technologies. Superlative performance, unique style: the Grande Utopia EM is not only a technological monument, it's above all an acoustic sculpture. The Grande Utopia EM website.
