Finally had to register here to chime in as a long time lurker... I found it extremely amusing that you're complaining about "cheap" capacitors on Audio Science Review, which is a community that is based on
science, rather than
status!
The Bennic XPP series are considered as premium capacitors in the
no-nonsense audio world.
It's also reassuring to see
@henz directly state, "All components in the crossover were selected based on thorough objective measurements and subjective listening tests." This is exactly how speakers should be designed.
Finally, let's be honest here — 2 Purifi woofers, 2 custom AMTs, and 4 passive radiators, all packaged in a well-designed speaker and delivered to your door for 4000 EUR, is exceptional value. Especially when you consider the pedigree of the people and companies behind the project.
