Like the Cassiano and the Arabba of our new series, the Vescova carries the famous German Accuton drive-units with
their unique ceramic diaphragms. Ceramic drivers are said to be behind a revolution in loudspeaker design. What is the truth? Read this brochure to experience why we have chosen ceramic driversDiamond tweeter – HighTech Made in Germany!

Since more than 20 years now the company of Thiel in Germany is dedicated to the design and manufacturing of ceramic diaphragms for loudspeakers. These diaphragms are thin and fragile but unite contradictionary properties like light weight, hardness and stiffness which are important for good diaphragms. The high speed of sound of ceramics shifts partial waves and resonances into the inaudible region where they can be cut off by steep frequency crossovers. These diaphragms enabled us to use our unique frequency crossover technology.diamond tweeter The same is true for the properties of the diamond tweeter (optional feature). Not only is diamond light and stiff, it is also the hardest material and the one with the best heat dissipation of all materials in the world. Especially important is the high heat dissipation as it prevents the voice-coil from becoming warm which leads to a compression of dynamics and worse resolution. In combination with our steep filter crossover this tweeter is almost indestructable.

The Vescova’s Technique

The Vescova is a 21/2-way speaker. The lower woofer is only applied for working in the lowest frequency region only up to 130 Hz. This woofer is backed by a vented enclosure with the port facing down to the ground thus increasing efficiency. We choose the deep cut-off frequency to prevent this woofer from radiating into the frequency region of human voices. The second, upper woofer faces a sealed enclosure on its back and goes up to 3200 Hz where the tweeter is taking over the sound radiation. As this woofer is emitting the most important frequency region the mids we choose a sealed enclosure as vented enclosures always colorate the sound due to cabinet and vent resonances. In contradiction a vented enclosure goes down deeper and the air of the vent is supporting the woofer for the deepest bass.

A genuine midrange-driver:

The woofer-midrange driver of the Vescova Due to its hard aluminum dye-cast basket this driver offers perfect stability for the huge magnet and excellent sound transmission by the thin bars.
