Why not put crossover networks in accessible compartments?

Because most designers don't want you messing with them. They work hard to dial them in just the way they want them.

Why not put crossover networks in accessible compartments?

Some have, such as Infinity.

It is also extra expense and complexity in a build, which raises retail prices, in order to satisfy maybe less than 0.01% of the potential buying public. That one in 1000 or less...who might tear the speaker apart and modify it.

There are other reasons to compartmentalize the crossover, and that is separation from the physical interactions of the drivers energy input into the box. To get the crossover isolated in all ways.

We use outboard passive crossovers, in the speakers we have made, over the years. Which makes it easier to go to active crossovers.

The Watkins WE-1 from the early 80's had a recessed area covered with a Plexiglass cover so that the crossover and the circuit board it sat on was visible. It was done not so the owner could fiddle with it; it was done because the crossover actually looked good and to show that the speaker wasn't just a cabinet with twenty bucks worth of resistors and capacitors in it.
