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!

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.
Most likely the benefits of adding inaudible content are inaudible.

It is known that sharp filters to remove out of band noise can effect the "in band" sound, however, that seems to be the only convincing argument for greater bandwidth (well beyond what you can hear) in audio reproduction.
I love my Fostex F200a Mid matched perfectly (to my ears) with the wonderful Fostex T90A-EX super tweeter, thank you JohnK!

A friend of mine uses the 'Townsend' super duper super tweeter with his horns and swears by it.
If you have a supertweeter crossed too low (like 15kHz) it will interfere with your main tweeter with unpredictable results. Remember that at 15kHz, the wavelength of sound is in the order of a few millimeters, so if you place your supertweeter off by a fraction of an mm, the interference pattern will be different. The high frequencies may be either enhanced or destroyed ... depending on the summation of waves by the time it reaches your ear.

You may or may not like the sound this interference, but of course that is up to you :)
Is it easier to add a super tweeter to horn speakers with better results than to add super tweeters to non horn speakers?
