the longmill I think were just tweeters, at least thats what they were sold as, although they may have originally come from a component set. They came with their own X-over too.
The front mid/bass is a pioneer. My electric window mechanism broke recently and destroyed most things in the door inc the original factory speaker. So I picked up a set (again off ebay) of mid/bass speakers for a few quid. They are much better than the originals. So thats why I upgraded the tweeters as the high range sounded rubbish in comparison. Got some more mid/bass speakers coming, caliber competition (yet again ebay for a few quid). Whichever is the best out of them and the pioneers will go in the front and the others in the rear. Then it just leaves me to get some tweeters for the rear.
