Characteristics and sound properties

This 2-way column speaker, ALTO II, designed as a 30 litre vented system, is another suggested application from the Alto series. The same driver arrangement has been selected as for the ALTO I but, here, the lower range octaves benefit from the enlarged cabinet volume and optimum bass frequency to produce powerful, responsive bass.

ALTO II is also well-suited to improving the sound of low-priced compact hi-fi systems.

The ALTO II can be positioned freely anywhere in the room, producing clearly defined spatial sound character.

Frequency- and impedance response


Extract from HiFi Test

"the elegant Alto II bass reflex column speaker fascinated us with its bass reproduction that would put many a speaker twice the size to shame."

Value for money: very good


Extract from Klang & Ton

"Its bass reproduction is not only very rich and very powerful, but in addition highly precise, full of detail and free of colouration. Both the base and lower mid-range remained perfectly neutral."..
"Music reproduction is airy and far reaching."

Value for money: very good
