For the 6th gen, factory tweeters were only available and came in the Ex coupe and 99-00 Si.I'm guessing these are the coupe/hatchback ones because the sedan ones are pretty hard to find.
No and yes. They do exist but they were not available for the 96-00 EX. They were available in other markets and also on the Acura EL.Sedan ones are hard to find because there is no such thing. Factory tweeters were not available for the 96-00 Civic Ex sedan.
