Angelus Crossover
The Angelus appears to be Bau's most ambitious speaker design, a departure from previous designs in that it included its own stand. The components in the Angelus crossover appear to similar to those used in Spica's TC-50.
Fewer electrolytic capacitors were used, which is good as the metal film capacitors are more reliable and considered to be sonically cleaner. Electrolytic capacitors are frequently used where larger values are needed because of their lower price and smaller size. Unfortunately electrolytics are prone to failure with age. I suggest you keep the electrolytic in the circuit as converting it to polypropylenes will alter the electrical characteristics of the crossover.
