CRESCENDO
CROSSOVER, BYPASS AND COUPLING CAPACITORS

The world's quietest film-and-foil capacitorsTM.

Crescendo high voltage, high current, high frequency polypropylene film and aluminum foil capacitors are designed for critical crossover circuitry, coupling and bypassing applications. Originally developed specifically to complement (via bypassing) other large value film-and-foil and exotic metallized capacitors, Crescendo capacitors have gone though numerous upgrades including improved conductor materials, radius soldered leads and a proprietary, ultra-low flux pure metal solder.

Crescendo capacitors' midrange and upper midrange is full and liquid while the top end is sweet and laid back; a tonality opposite that of most modern "audiophile" film capacitors. When employed in bypassing applications, the Crescendo's tonal characteristics are blended with those of the base cap, producing an overall voicing which is harmonically correct and more natural in the top end without sacrificing detail.

The most unusual quality of this capacitor is its absolute freedom from intertransient noise. In most tweeter application, we have found that unnatural sibilant emphasis and cymbal overhang can be corrected by employing the Crescendo capacitor as a bypass, indicating that those qualities are actually an artifact of the base capacitor. Sound stage background with this capacitor is the quietest we have ever found.

We have also employed this capacitor, particularly the 1.0F, as a bypass capacitor in woofer network shunt sections. Surprisingly, this application seems to increase woofer speed and precision significantly.

Construction:

The Crescendo film is custom made high frequency, high current, high voltage polypropylene. The film is US Military qualified and designed for minimum energy storage through both electron capture and molecular deformation, particularly in high frequency applications.

Crescendo capacitors are wound under tightly controlled uniform tension conditions. The computer controlled, fully automated Swiss-made winding machines are precisely calibrated to insure that both the dielectric and conductor tensions are held constant throughout the capacitor volume. By employing this winding method, we allow the overall tension on both the dielectric and conductor to be reduced, eliminating film elongation and conductor microfractures. Air is then removed from between the film and foil layers via a proprietary process, and the windings are sealed with a high conductivity, pure metal end cap. Color-coded, silver-plated OFC Copper leads are then silver-soldered to the end caps by hand, and the end is epoxy filled.

Because the winding conditions have been optimized for each capacitor value, precise control over these conditions repeatedly reproduces the original performance characteristics regardless of capacitor value or production run.
