Hi, As a newbie, let me first say thank you for the information, time and dedication this site represents. What a wonderful resource! Had I found it sooner I might not be asking these questions.
That said, I've had the pleasure of owning a pair of 4315A's for the last 30 years. So, when they were scheduled for downtime for new surrounds, I naturally thought something JBL would be nice in the interim. Hence the 4311's. OOPS! Not what I was expecting, though had I looked at specs first...
So, now I've done my homework (belatedly), and my choices seem to be:
1. Sell them. (There seems to be ready market.)
2. Learn to live with them. (Not likely.) or,
3. Make them something they're not, i.e. such as swapping out the mid and tweeter.
I'm leaning towards 3, minding that just buying 4412's is not as simple as it sounds. However, changing drivers raises crossover issues. Arrgh!
