JBL L26 - bad crossover?

[sneakyimp]

OK so I took the woofer out and snapped some photos of the inside. The pot has no vents on it as far as I can tell and the components all appear to be mounted on a piece of particle board which is glued and stapled (WTF??!) onto the inside of the front face of the cabinet. Seems to me if I need to make any repairs, I'll need to take the components out. Any suggestions about how to remove this without damaging anything? Obviously, the plan is to eventually return the components to the inside.

Based on the circuit diagram (thank you, cjpremierfour, there seems to be a bigger one here), I believe the parts correspond as follows:
* 8-ohm pot - silver can on the left, duh
* 1mH inductor - coil stuck under the hotglue/glob of goop bottom center
* 0.5mH inductor - coil exposed near the insulation to the top
* 8uF capacitor - carboard tube on the right (with the part # stamped on it duh)

I tried the simple low-volume-no-bass test on all 4 tweeters. The new ones (LE25-4) work. The old ones (LE25) do not. It would appear that the speakers suffered some trauma -- at least enough to blow the tweeters, which may explain something about what happened to the crossovers.

I ordered a multimeter from newegg which will hopefully help with circuit diagnosis.

Any tips would be much appreciated. I'm wondering if it might not be easier to buy/build a new circuit like the one recommended here.
