Super tweeters, are they worthwile?

Hello guys
I've been reading some infomation on the web about super tweeters and I've got curious.
First I didnt believe in subwoofers, I thought the would only add bass quantity to my system and then I got convinced and I tried one. Well, I couldnt believe how much it improved the 3D image, making it rock solid and so real. And I thought soundstage was mostly the tweeters job. 
Now I read some guys swear that super tweeters can also improve the soundstage, 3D image and bass!!  Well, If a sub can improve the mid and high frequencies, I think I can believe super tweeters could improve bass. 
First, I would like to now your experience with super tweeters, please only the ones who actually tried them. 
Second, if I listen all of my music streaming Tidal hifi (44.1 kHz), does this sample rate have ultrasonic infomation for the super tweeters to play? If not, does software or hardware (DAC) upsampling delivery it? 
Finally, wich super tweeters would you recomend under 1k the pair? I mean, ready to plug and play. I dont have the expertise, nor the time and patience to build crossovers, etc.
Just to mention, I live in a country where I dont have the chance to borrow them from a dealer with a trial period. I have to buy everything blindly. 
Thanks!!

I recommend a visit to an Audiologist to test your hearing and find out where it drops off!

Super tweeters can enhance the music including the sound stage as you noted in your opening questions. I own the Townsend Super Tweeters and I have found the results very positive however they seem to work better with some speakers verses other speakers, but they work, most likely depending upon the tweeters used in various speakers. 
Sorry, that's the only question that you asked that I can answer.
If you choose to purchase a pair of the Townsend Super Tweeters for best pricing (before you purchase new or used) contact Nicholas Besley of The Emporium in the United Kingdom.
IMO;Those that say Super Tweeters (a really good pair) don't work most likely are stating an opinion vs actually owning a pair and listening to them.

I used Decca ribbons, and then Sequerra ribbons as part of a mini-HQD system many years ago with a subwoofer. They increased the frequency spectrum, but like most add-ons to the original Quad ESL (aka '57), there was a coherence issue-I did manage to get them to blend and I guess they accomplished part of their task in making the high frequency sweet spot (within the range of the super tweet) less constricted- a notorious fault of the old Quad. 
Still have the Deccas, they need to be repaired. I kept them mainly for artifact value. Are the Townsends still in production? I think there was another brand in the last few years that is no longer in production? 
Old school isn't it?
This came up in a discussion of the big Bozak, for which it was common to use some piezo tweeter as an add on....

You guys are probably too young 😛 to remember the Ultra Tweeters from Golden Sound. The output of the Ultra Tweeters was 3 GHz, nothing below that.
