Hi, this is the first time I have ever been on a forum and I am not really sure how this all works. Any advice is welcome. I am a custom cabinet builder and I love speakers. I like to purchase speakers that are in rough shape and build new cabinets for them. I recently took a rp280f that was damaged and turned it into a center channel speaker. I would like to rebuild a pair of tangent 500 speakers to match but want to make a better cab. I’ve heard people say it has essentially the same components as the heresy 2 but doesn’t sound as good. What can I do when I rebuild them to make them sound better? Can I change the horns to fastrac horns? Thanks. Here is the rp280f that I converted.
