I have JBL 2226H 15" woofers in 4507 style enclosures. I believe these are tuned to 38-40hz. I'm looking for suggestions on new or used tweeters/horns to match up with them. I've got a budget of $200-$250 for the tweeters & crossover.

I don't know how to design a crossover though, so I'm looking for proven designs.

I listen to rock and jazz and classical, though these speakers will also serve as home theater main L&R's.

Thanks for any suggestions! Driver doesn't have to be JBL and I'm open to horns. I'm using solid state 140watts per channel.
