ALTO 111 C Art. No. 5972 (1 pair of speakers, assembly required)Characteristics and sound properties
The ALTO III c has been designed as a 3-way column speaker with an inside volume of no less than 55 litres. The twin bass arrangement using two W 170 S 8 Ohm drivers in parallel guarantees very powerful low-ranging bass reproduction, that comes across crisply and impressively even with a hard-hitting beat. >From around 450 Hz upwards, the 10 cm mid-range cone W 100 S 4 Ohm takes over, mounted in its 3 litre enclosure. Single instruments and solo voices are reproduced throughout the mid-range in a most tangible, crisp fashion, where the precise definition of virtual sound sources and their associated range layering, so typical for good mid-range cones, comes across well. Above about 3500 Hz, the sound character is rounded off neatly by the crisp 19 mm tweeter DT 94 8 Ohm. The exuberance demonstrated by the ALTO III c promises to put listeners in a good mood and keep them there for several hours of musical pleasure.

The cabinet consists of boards stuck together (butt jointed), making construction a simple matter. The two boards for the closed mid-range compartment are fitted inside the cabinet before the last side panel is glued in place. Before this, an 8 mm hole has to be drilled in the rear panel of the mid-range enclosure for the connection leads. The crossover unit is mounted on the rear panel behind the upper bass cut-out.
The damping of the speaker uses eight mats of damping material pushed into the cabinet. To this end, the mats are folded once longways and once cross-ways and pushed into the cabinet in such a way that the space behind the bass tubes remains free and the rest of the space inside the cabinet is loosely filled.
