my a-pillar in my car is very close to the factory location of the tweeter, and the other day i got some idea to put a pair of tweeters or a tweeter and 2" midrange driver in there for some upper extension.
or a pair of tweeters.
i like the highs.
regardless, ive seen it done, but does anyone had an experience to hear them. does it sound good? not wanting opinion, facts. please.
