8 Excel W12CY001 looking for a DIY project to fit in

The idea is to make an independent module with 2 W12 seas as in the photo of the Schweikert VR6
And if someone is so kind as to send a drawing with the croosover with the filters and capacitors that I need and if possible the drawing as if it were for a 5 year old child well thank you very much in advance

I don't get the point to add a module with two 12cm midbasses when you already have a satellite with a 15cm high midrange.
Anyway, the integration it's not easy beacause a passive filter for a 4-way is complicated and expensive as you will need high value coils to linearise the impedance curve at low frequency. It would be easier to use an active xover.
If I were I would build an MTM satellite with the seas midwoofers and use the Scanspeak as a subwoofer.
 
Hello, good, the idea is to make everything independent as 3 independent speakers and power them separately since my amplifier has 8 outputs at 160 W per channel, so I want you to give me your help to be able to make an independent crossover for that only speaker, which is the one in 2 seas w12cy woofer, because I already have the rest clear, thank you
