This speaker crossover. Advise on improvement


I have a 2 way speaker with two Vifa permium line 14cm mid/woofers and a Vifa ring radiator tweeter. I like the sound but I was wondering if using better parts in the crossover can improve the speaker further.

All I know it is a second order crossover. At this page more can be found put about the speaker and the filter.

According to the site tinfoil and polypropylene capacitors where used, also the resistors are metal film.

Depending on quality of present caps and resistors, you could hear anything from very little improvement to major improvement. You need to know the quality of what is in there now. I can't tell from the picture what cap that is.
Don't overlook your soldering skills. Less than the factory-quality joints will most certainly negate any benefits of the better components.
If the speaker is biwire friendly, consider an active XO. This will also require biamping, but this is where the real hi-end magic comes from
