New DIY Project

Does anyone have plans for a build similar to the Fern and Roby Raven utilising the SEAS FA22rcz 8" fullrange driver?

Looking to challenge myself and think these would be great fun to put together.

Any help would be very much appreciated.
Yes don’t put the driver at the very end of the box if you can. You will have to deal with sharp drop of output at f=345/2*box lenght.
