Why not put crossover networks in accessible compartments?

Sorry, I was unclear about something:

Wilson, like other highly regarded makers, uses straight off the shelf parts

Here what I meant to say was "off the shelf drivers."

Hope that clarifies.

so how do you know what they use?

No one does, it's a trade secret. A secret most other manufacturers only do minimal work, if any to hide. For instance, using branded OEM caps. You can't tell if they are expensive or cheap and you can't buy them  yourself.

I should point out not all speaker makers use cheapest possible parts or go through any more trouble than putting crossover components in the speakers.

B&W uses Mundorf in some speakers, as does Magico and Joseph.

I think Wilson kind of helps answer this question. They literally pot (encase in black resin) their crossovers so you cannot see anything, even if you disassemble the speakers.


Wilson, like other highly regarded makers, uses straight off the shelf parts you could buy yourself. If you knew what the crossover values were, you could make a straight up clone. Focal used to have little windows so you could see the parts.


It’s also true that the economics are such that putting in high quality crossover components is rarely a win for makers. This makes a couple of brands like Focal and Wharferdale ridiculously good upgrade targets.


Of course, if you want to play with parts this badly, the DIY speaker kit market is probably what you should be looking at. :) Lots of kits and plans out there which you can tweak to your heart's content.
