I DJ with 2 sets of Pro Media 4.1's and this weekend at a gig 3 of my speakers were knocked to the ground from about 3 feet and no longer work anymore. There is nothing rattling inside I opened them up and there are no visble wires loose or disconnected. However, there is a bit of a burnt smell to them. Kind of like the got too hot and when they were knocked to the ground it FRIED them or something. If anyone has any suggestions or has had this problem let me know . I want to return them but not sure if they are covered in warranty. Thanx.
