Characteristics and sound properties

Well designed 2-way speakers with excellent mid-bass speakers and equally good tweeters can work wonders in terms of their spatial qualities and localisation. One of the reasons for this is certainly that the a large, absolutely critical frequency range (up to around 4,000 Hz) is covered by a single loudspeaker driver. In other words, there is only one soundsource and no possibility of interference or loss from an intermediate crossover. In addition, the narrow baffles in such speakers tend to have a positive effect on omnidirectional sound distribution and the intended related characteristics.
The SKYLINE is indeed a 3-way combination, but, in contrast to usual practice, with a very low cut-off frequency between the low- and mid- to low ranges (here around 300 Hz). This keeps the cone still, but the system still manages to produce sufficient low-range bass. In a sense, the SKYLINE is nothing more than a 2-way speaker with a subwoofer.
The WS 13 BF 8 Ohm is one of the few mid-range cone drivers, that produces a completely linear frequency response across the entire transmission range up to 5 KHz. If the SKYLINE is placed in a room with at least moderately good acoustics, the exact positioning of the instruments or voices is immediately noticeable. Even if the listener is not in the ideal central listening position between the speakers, the SKYLINEretains its precise positioning characteristics.

Extract from Swedish Audio Video

"We also listened to 'Cantate Domino', a classical Proprius recording that often creates all kinds of problems for many loudspeakers. We selected a short passage with a soprano solo and some organ. The spread was brilliant, as were the highly pleasing ambience and clarity of detail. Chords were very finely resolved. The verdict was "very good", the recording was reproduced very accurately .“

One comment among many was: "More music than loudspeaker!“
