The way these are typically deployed can be analogized like running your speakers full range then throwing in a subwoofer. Basically you are running double bass.
A lot of 1" dome tweeters get directional above 5KHz, i.e, they start beaming when you are more than 30 degrees off-axis. Remember basically there’s no real musical output above 10KHz in most instances. It seems the super tweeters function in most cases to simply expand the dispersion of your speakers in the 7-10KHz high frequency range.
It can be useful if your tweeter beams at high frequencies--this will be even more obvious if you have a 1.1" or 1.25" tweeter. However some 1" dome tweeters have good horizontal dispersion out to 60+ degrees and won’t need this. It really depends on the drivers you have.
