Why do people use tweets in the A pillars, that's not 1 foot from the mid?
In the end it all comes down to personal preference and interior of a car, from what ive read and experienced, the near the tweet to the mid, the better; and you somewhat can overcome the need to TA.
But every car has different response, i my tweets near to the mid, on the dash, not to farther in, towards the windscreen, some have their tweets in the sails, some in the A pillars and some in the doors.
My crown has tweets in the door, near the door handle. And they sound really nice. Since shahid bhai's ride is in discussion here, i liked it when he had his tweets in the doors better than when they were in the A pillars and now since they are in the sail pannels, they sound even better.
