Germany's Ascendo has always produced elegant and
distinctive speakers that seem relatively straightforward in terms of their design. But a
close look reveals quite a bit of technical innovation, and the new System F loudspeaker
priced at 12,000 per pair is no exception.
The System F is actually a four-way loudspeaker -- its
rather simple looks overshadow this fact. There are a front-mounted tweeter and woofer, a
rear-mounted ribbon tweeter to improve ambience and provide better spatial cues (shown
above), and an internally mounted woofer whose output is delivered from the port in the
Ascendo designs its speakers with first-order crossovers,
for minimum phase shift, and attempts to time align the drivers. In the upper-end models
like the System F, the tweeter's position in relation to the midrange driver can be
adjusted for the listening position.
The System F also has a unique design element that the
other Ascendo models don't have -- the designers paid close attention to the drivers'
dispersion, not only on the horizontal plane but also in the direction of the floor.
Ascendo found that this early reflection from the floor -- sometimes called "floor
bounce" -- can obscure detail and compromise imaging if it's not well controlled. By
controlling the dispersion in this direction, Ascendo aims to minimize the effect of floor
A look at the top part of the woofer/ribbon-tweeter section
on the back reveals a measurement guide that's used to time align the drivers at the
listening position. As we said, this is at first a seemingly straightforward speaker
design, but in reality there is a lot of technology packed into it. Plus, it sounded
