What's the purpose of these resistors? This is the driver from a recabled Pro2500. I can't find any pictures of stock drivers so I'm not sure if these were used with the original wiring. Each one has one blue stripe that goes all the way around and lettering that says B2. I was wondering why they are there and what would be the effect of removing them or changing them.

Those are zener diodes. They protect the voice coil from excess voltage.

X2. I would leave them in place. They'd probably sound exactly the same without them, but you'd stand a higher chance of frying the voicecoils if they were removed.

Okay, I'll leave it as is. One driver seems to be louder than the other so I was wondering if these could have any affect on the volume.
