Art. No. 5967

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.


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
