Been thinking about recapping mine, they have the bolt on the bottom, where is the crossover on these? Thanks in advance!
I only had one - I found it at the dump and took it home to try to find out what it was. I never found a way inside except by chiseling out the woofer which was glued in. My memory is that the crossover has very large diameter air core coils, and quite a few components, but I can't remember if they were electrolytic or film.
Given the difficulty and risk of bashing your way in, if the speakers sound good, I'd just leave them unopened - electrolytics can reform and act as they were intended to act, and sometimes changing them is counterproductive since you also change the equivalent series resistance.
On the other hand, I'd replace the cloth with foam, if only to make the top and bottom extend less from the apparent body of the speaker. Better proportions will soothe your psyche, making the speakers sound better.
Gluing it back might work (and it only needs to be strong enough to seal the top seam and damp everything a bit, so JB weld or similar ought to be fine), or you might be able to remove the entire chipboard block and fit a new one.
