Characteristics and sound properties

The ALTO LINE is a slim, 2-band column speaker with two 13 cm mid-bass units and one dome tweeter.
Due to its slim design and the correspondingly small footprint, this model is ideal as a free-standing speaker in smaller rooms.

The spatial separation is well handled by the speakers and can, as a result, produce clear sound characteristics even in "normal" living rooms.

The unusually broad range bass spectrum for a speaker of this size, that remains crisp even at higher output levels, is a point worthy of note.

As a result of its balanced, crisp sound characteristics, and the finely detailed, exuberant high-frequency output, the ALTO LINE can be considered a fully-fledged member of the ALTO speaker family.
