If I set the super tweeter at 8 kHz setting, will both my floorstanding speaker tweeters & the super tweeter will play the same audio at the same time? Or will just the super tweeter play audio?
The tweeters on your floorstanding speakers will continue to function as normal regardless of what crossover setting your use on the super-tweeter, the super-tweeter just extends further up the frequency range .... so yes all tweeters will play audio all the time.
