Since this thread is too quiet, I'll bite...
My latest project is to get another power amp, a Beheringer digital crossover, some horns, etc. so I can try out the
Selenium D250-X's I got, coupled with some APT-50's with a passive crossover (too cheap to buy a third amp). Depending on how this
works with my Pi-4's, I might get/build a set of Wayne's midhorns. My issue isn't so much with spending the money, but explaining to my wife why I might
want "more speakers." Its a bit of a game I don't mind playing.
It is an expensive experiment to test $60 worth of drivers. Is this hobby a bit nutty or what?
