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.


Also perhaps to do with the fact that the stereo 'information' is
carried by the higher frequencies which are lost in the carpet and seats
in most cars so many manufacturers have gone for seperate mid-high
speakers (not just tweeters) in the ends of the dash or the top corners
of the doors. It also means that they can then fit lower quality
speakers that do not need to handle full range in the doors and get what
the punter perceives to be better quality (i.e. more bass.)

You didn't seriously imagine that it's possible to get a proper stereo image
in a car did you?
