A lot of these types used to "squawk" as I remember (even the JBL originals), the bass gains swamped by the midrange sadly. Not as fun looking, but you could look out for the later JBL versions (crackle black finish only for the pro market) - which I think had "B" and "C" monikas after the 4310 and 4410 numbers (I forget now, but new, the 4410C? was around £1300pr ten or so years ago IIRC) and with much better crossover design to bring the concept up to date......
I can't go on and I can't go back, I don't feel so matter of fact,
I tried and tried to make good sense, What's the good to try it all again?
