I am looking to rebuild this crossover, figuring out the values and replacing them on the old crossover hopefully will not be much of a problem and it is well within my abilities (at least i hope so). but I have read that some do not think that the stock crossover points are ideal and they advise modifying it

the stock cross over points are 1000hz and 6.5 khz.

now this is beyond my knowledge of electronics. i will need schematics and list of parts and instructions. if I have schematic i can draw a pcb and and order it to be built but i will need to start with a complete ready to go schematic.

I have looked at some other threads about this crossover and i found the orignal diagram, but i was hopiong to get some good advise on how to rebuild, what components to use? and how modifications to make.
