hello. my 3 year-old daughter recently played with my B&W 302 which i use for my surrounds (it was not mounted during that time). she pressed on that round convex thing at the center. she did that to both the tweeter and woofer and now both drivers' middle part are depressed and concave. i haven't been able to try them yet. how would this affect the speaker's performance? and, any idea how much it would cost to have the speaker repaired?
