ELVIS 12/12M MKII speaker enclosures is just one of the many Alto products that a

talented, multinational Team of Audio Engineers and Musicians have developed with their

great passion for music. We design all our transducers and cabinets in Emilia-Romagna of

Italy, a low-land famous for music and fast cars. In fact, Lamborghini, Maserati and Ferrari

are made just a few miles away from our design centers. The same area has a long

tradition in designing and manufacturing some of the world's best professional transducers.

Your ELVIS MKII speaker cabinet is capable of very high sound pressure level and it has

been created to give you a performance that is better than any loudspeaker in this range.

They are flexible in their passive configurations and can be used with single and multiple

Subwoofers.
