Thoughts on adding a Super tweeter .

I have posted something like this before,but thought I may ask for follow up input.
I already have a superb tweeter,ruler flat to 25khz(titanium),yet wonder if something like the Townshend(it starts to come in above 20 khz,and goes out to a zillion khz,almost)or Murata(comes in at 15 khz,Too low?, goes to a trillion,just kidding btw,)would add "real world"enhancements to my existing set-up.I have NO problems,with high freq performance,as of now,yet in this hobby,one can always be surprised.
Any thoughts would be most appreciated!

Best!

Most loudspeaker are not flat on axis to 20khz, off axis even less so, so many super tweeters are running in the range we can hear, we custom set crossovers but many are arround -6db at 15khz.Then phase maters but crossover 25khz higher not as much.

The only loudspeakers that are hard to add super tweeters to are ones with cabinets that dont allow super tweeters to be close to main drivers plus you need to beable to move the tweeter to ajust time arrival. A full range driver and horns are fairly easy to match too because of hi-frequincy roll off.If you have good extention above 25khz I wouldnt add one but most loudspeakers dont and many dome tweeters roll off far below this even if manufacter states 20khz is probly at -3db or greater. And off axis drop is is even lower for many domes.

No one super tweeter for all loudspeakers, each super tweeter needs to be carefuly matched in level and crossover so no over lap,phase,time problems or boosted frequincys. The one tweeter that matchs all is just asking for grief maybe you will get lucky and it will match but your taking a chance. So if your thinking of adding one realy look into it and maybe DIY or have a pair custom built than you can also match finish as well as transducer crossover.
