Characteristics and sound properties
The ALTO I is a 2-way shelf-mounted speaker with a cabinet volume of 13 litres. Apart from the 20 mm tweeter cone, the cabinet contains a 17 cm diameter mid-bass cone.
The sound qualities of the ALTO I are "warm" but with crisp, high-range reproduction.
This kit is ideally suited to replacing the more basic speakers often supplied as standard with low-priced hi-fi systems and thus improving the overall standard of the system.
Since the bass ports are at the front, the ALTO I can be hung on the wall or placed in bookshelves, facilitating good bass response even in rooms with difficult acoustics.
