Default Busted BW DM4s

Hello community

my beloved BnW DM4s have blown, due to a forgotten condenser mic and an amp at full volume.

They had fuses in the back with a higher amperage than the originals, which I had intended to eventually replace with the normal 2A but forgot about...

At first they were making this weezy sort of pathetic noise, then the signal stopped altogether. I thought they were completely ******, but after changing the fuses they are still making noise.

Does this mean that I can just replace drivers, or could there potentially be damage to crossover as well?

I've never done any speaker repair, so any fingers in the right direction would be great!

Thanks

First, eyeball the crossovers.
Anything toasty, or exploded? Smell anything burnt in there?
Now gently move the woofer cone. Smooth? Take your multimeter, single ohm scale, and check DC resistance of all your drivers.
Report back.
