After you switched the position of the speakers open the cabinet to see if anything fell off the back of the driver(s) like the magnet, or crossover components, and etc. Make sure all components are tight and not dangling around inside. Also make sure the wires are snug and fitting properly on the crossover and post.
I received a speaker once where in shipping the magnet structure had fallen off the rear of the driver and hit the crossover causing many problems. I hope you didn't experience any cabinet damage. Good Luck!
