Fostex FE166En help with a custom box

I’d like to find some build plans for these Fostex FE166En drivers, I’d like to also add some highs with some Foster Ribbon tweeters
I’ve found the basic plans for these drivers but would like to see what others have come up with and would share the plans with me
And also any info for using a dsp or crossovers with and info on any settings for either
