Blew the tweeters out of my RTi70's. Sent an email to Polk customer service. Haven't heard anything back, but have had to send things in before. I pulled what I think is the tweeter, a magnet with foam on the front. But there was still a copper coil and and wire connections. Should this have gone back as well? Didn't see how those would come out. Tried hooking up a tweeter from a rti28 that I have and nothing came out, so I'm wondering if it's the coil thing that is bad.
