Has anyone done any upgrades to the Infinity RS 1-B ?

Infinity RS 1-B speakers active crossover? I know that the passive crossover can (and I did) be upgraded with new caps etc.....but can, or should, the active crossover be upgraded?
I love the system and just wish to get the most from it.
I would appreciate any input. Thanks all!!
Memories! I still have a pair of RS1x in the closet.
You can upgrade the caps/wiring inside the active with good results.

It can and the foremost authority on this speaker is Bill Miller of Miller sound. Send me an email and I will get his info and send it to you.
