Sarastro II Upgrade
If you own an original pair of Sarastro loudspeakers,
they can be easily upgraded to the Sarastro II!
The Sarastro II uses the superb and proprietary Verity Audio resonance free, pure aluminum ribbon tweeter that was introduced in 2007 in our reference Lohengrin II. This new Verity ribbon tweeter incorporates a custom-wound, high-purity, impedance matching transformer that exhibits very low resistive and inductive losses. In fact, our research has shown that, due to the low impedance characteristic of a pure ribbon aluminum foil, overall circuit losses in the driver become much more critical than in other designs. Our unique design ensures there are no such losses through a clever short signal path that is implemented in a non-inductive environment. In sonic terms, this feature alone conveys an astonishing level of high-frequency purity without memory distortion, however many other design elements of the driver, from optimally focusing the magnetic-field in the gap, through designing the rear chamber to properly address the rear-wave of the ribbon, make this exclusive pure ribbon one of, if not the absolute best, tweeters ever developed.
As much it would have been easy if the new tweeter could simply have been installed in the original Sarastro without much work to gain the benefits of its sublime performance, getting the entire loudspeaker to
The upgrade consists of the following changes/upgrades:
- Installation of the new Verity Audio pure aluminum ribbon tweeter;
- Removal of all original crossovers and internal wiring
- Installation of new internal wire;
- Installation of new woofer crossover;
- Installation of new midrange/high-frequency crossover;
