Time wise it didn't take too long. The most time consuming was getting all the angles (especially compound ones) in the finishing detail. I build furniture as a hobby so woodworking is getting a little easier.
As for plans. Well I'm afraid I don't have the patience for a step by step layout explanation. The best I can suggest is visualize what you're doing and lay it out on paper. I'll make several drawings and then finalize the details on paper before I start the actual build. This build is basically a inner cabinet of 3/4" MDF with a 1/4" layer of veneering. The stands are made of 1" laminated mahogany (2 layers). There is a hidden channel to conceal the wire going up to the drivers.
hopefully this will give some inspiration to others for their build.
