HI fi Danish speaker company ....super disappointed in those crossover "boards"(more like a few pieces of thick carboards with probably the cheapest electrolytic capacitors and the cheapest mkt "bennic" film caps.
XGlowie : those replacement caps you used look very nice , I am not familiar with the brand .

AudioCore is an East Europen brand with good value for its cost. I have not found polypropylene capacitors Mundorf with suitable parameters in Moscow excluding electrolytic capacitors in the LF section.

I used ClarityCap CSA/ESA 250Vdc Series Film Capacitors and they are very nice and not as expensive as same rank Mundorf caps(according to this: Humble Homemade Hifi - Cap Test)
It is clearly a wood carry board, and I would actually prefer point soldered boards over a PCB, but each to his own I guess
In the photo there is also a capacitor at 22 uf 100 V, next to the woofer section at 150 uf. Why is it not reflected in the diagram? The effect of replacing bipolar capacitors will be 100% Low-frequency section can not be changed. In a good way, after the replacement, it would be better to measure the frequency response. Since the frequency response was measured at the factory in Denmark with electrolytic capacitors. The midrange frequencies may creep up. In principle, I am satisfied with the sound of opticons, And in the circles of sound lovers, the value of capacitors in frequency filters is greatly overestimated. Another question is that over time, electrolytic capacitors can change their parameters and then the frequency response will NOT CHANGE FOR THE BETTER. And the time will come to replace them! If you pay attention to the separation filters of top Japanese acoustic systems from the 70-80 years, then electrolytic capacitors were used everywhere there! And it didn't stop them from being the best!
