My speakers don't sound right.... I don't know what's wrong but they're not as loud as they used to be. I cranked them wayyy up about a couple weeks ago and they haven't sounded right since. I'm trying to diagnose where the problem is. I wonder if the Harmon Kardon couldn't hang. It's almost like the horns aren't working but they sound like they are. maybe I should open them up and disconnect the woofers to see? I wonder if running the 16 ohm c and the 8 ohm E on GPA N1600 crossovers might have done something? Also they kinda sound out of phase although they didn't sound that way a couple of weeks ago?
