I would like to embark on a custom crossover for the new Westlakes. I noticed several members built custom 4-ways for their 4345's. I would like to do the same. Not sure I would continue to use them but would like to experiment.

I'm wondering if one of the members who has done this could give me plans and help me modify those plans to crossover at 400,1.8k and 8k? Driver compliment is as follows:

128H-1 x 2 @4 ohms
2122H x 1 @8 ohms
2426J x 1 @16 ohms
2403 x 1 @8 ohms
