Send them to me for proper disposal? 😉
The world, my friend, is your oyster. The mighty F200a is one of the finest FR / WR drivers available and there are lots of things you could do with them. How big do you want to go with the cabinet? If you want modestly big, this should do the trick nicely (especially the curved-front version): http://homepage.mac.com/tlinespeakers/FH/download/Chang-NBVR-map-140807.pdf

Hm as they are not mentioned there do they fit anything changing ?????
Sounds too good to be true to me...

well if it fits without anything changing, maybe my speaker as the woodwork does not look horrible complicated, is rather small and narrow, simple and a smalish FET amp could do the job.😀
The F200a requires the same volume as the 207 I designed it for, so it's a straight swap. Flat to 40Hz. Good enough?
The rear triangle deflector size is up to the builder. So long as it's long enough to prevent cross-talk between the upper & lower throats, that's fine. 1.5in should do. An internal brace (not pictured) would be useful as well.

I know that feeling.
You can resort to a mixture of MDF & chipboard. Not as good as BB ply, but it's a whole lot better than nothing.
Laminate 1/2in MDF to 3/4in MDF & you'll push panel resonance below the passband of the cabinet. Use that for the sides, the top & bottom, & 3/4in chipboard for the other panels. Should do a decent job.
