They are dual 2 ohm and are actually a full range driver. After about 9k they fall off pretty bad. Harmon used these in one of the home space saving subwoofer. Might have been a computer set up. They were also used full range in mini/bmw in the hk systems. Also about a dozen other products over the years. But alpine tweets i have went well with them.
Sorry guys, I'm now into the busy season at work. If you have offers for specific items go ahead and make them. I don't have time to play the games at the moment. Don't mean to be harsh, i just don't have much time on my hands
