OPTIMUS IN FRANK O. GEHRY’S ART WORK. El Ciego, Álava (Spain). The famous architect Frank O. Gehry, author of the Guggenheim Museum in Bilbao, designed this 5-star hotel with 43 suites. It is located in El Ciego (Álava), in the so-called "city of wine", next to the old Marques de Riscal winery, a wine therapy spa, a restaurant and a conventions and meetings venue. In order to provide a high quality sound, more than 100 two-way ceiling speakers have been distributed. The speakers have a metallic rear dome and diffuser for high frequency dispersion.
