Hi John,
No spec's? It must have a rated power, impedance and crossover frequency.
It looks like just an inductor for the woofer and just a capacitor for the tweeter. The cutoff would be so gradual that the woofer will still tweet and the tweeter will, well, maybe blow-up as it tries to "woof"?
It looks like it has a "polyfuse" or something to make it sound intermittent when you turn up the volume.
