Opera
Opera loudspeakers immediately appeared as a fusion between the old and the new: between traditional Italian craftsmanship in cabinet-making and the most advanced acoustic technology. Every Opera loudspeaker, even the least expensive model, follows a tried and tested philosophy of design: the use of top quality materials allied to carefully applied basic principles of acoustic science. Today our loudspeakers are exported everywhere, from Europe to the Far East with relevant space on the most important hi-fi magazines.
