One of the tweeters on my alpine type r 6.5" components in the rear has died on me, so now I'm looking for a new set of tweeters to replace them. I don't think I can buy a set of the exact same tweeters, so I'm just looking for something that can be amped to 100 watts/channel so I can run them with my alpines. Preferably 4 ohms, otherwise I can build a new crossover to make them work. Mainly I listen to country music and other old stuff, so I want something to work good with Johnny Cash, Elvis, etc. Any suggestions? Preferably not stupidly expensive.
