China and Taiwan have many coax home speakers/drivers, though not nearly as many as fullrange. Audioclips mostly sounded quite good but on undemanding music. I shy away from Ti tweeter in general so most got eliminated. Besides Tannoy Precision 8 coax (paper cone, Ti tweeter)+woofer and (OEM/clone?) LS50 Meta 1793 (AlMg cone, Al tweeter) projects (and Mg tweeters only from 5" Fyne F-1), I have a pair of 5" CF-Ti coax speakers branded Taulssen. Harpsichord strings' sympathetic vibrations in the soundbox to die for. Too much of a good thing.
So before tackling coax driver design maybe a trip to China or Taiwan to sample the local fare (or feast)....
