Sonab OA-14 Crossovers

[anathema]

Hi Everyone!

I'd like to upgrade the crossovers on my Sonab OA-14 speakers. However, I've not been able to find a spec sheet or schematic on the web for these speakers. If anyone has attempted this before, I could really use some advice or a run-down of the parts involved.

Thanks heaps!
