It occurred to me when fitting some new car speakers that a dual
concentric design would be ideal for this use. But they all seem to have
tweeters just stuck on the front. Any reason why this design has fallen
out of favour?

**Perhaps people have finally discovered what I found a few decades ago:
They sound like ****. Given that midrange frequencies are being bounced off
the back of the tweeter, the result ends up sounding like a pig's breakfast.
I've never heard a decent dual concentric car speaker. Perhaps it's due to
the shockingly bad crossovers used. Maybe it's just the cheap, crappy
drivers.
