Oh, yeah....#'s 1 through 8....
Enjoyment primarily....making my modest investments punch above their weight....diy-ing a speaker type that I enjoy but the commercial versions are out of reach or too old and compromised to restore without factory assist.
So I'm literally rolling my own cones creating a personal variant just because I can.
It's involving, 180 out from what I've used to do.
One concept that intrigues is a line source version, just for grins....modules stacked, flipped at the top end....'bout 72" tall overall with some subs.
Thinking a sub swarm might be interesting with 4 line columns...
...not the usual bucket filler, but someone's got to do it. *L*
