Those crossovers are a disgrace, just look at those tiny resistors, carbon types too, with no business being in a crossover at any price point!
I have auditioned Vienna speakers twice recently with my friend. They are another on the list of speakers too dreadful to mention. They are absolutely awful.
The dealer wishes he had never touched them. He can't sell them at a steep discount, alongside B & W and Dynaudio. He is yet to sell one pair!
Unfortunately that sort of thing you have uncovered is common in the loudspeaker industry. I keep repeating myself, but there are far more dreadful speakers out there than good ones. Unfortunately a lot of the dreadful ones still come with high price tags.
