not really. i just tinker
i tend to find most car audio tweeters and hard domes too harsh, so i play more with custom audio stuff more in search of a more natural tone.
i tend to find myself gravitating towards dayton and peerless gear, not for any particular reason, other than the spec sheets seem to more lend themselves towards what i'm looking for in either tone, or just a different approach.
i recently bought a set of aiyima tweeters that copy the peerless design, but haven't had a chance to mount them up to try yet.
