There are so many factors involved that could produce what you're hearing but my best guess are the metal dome tweeters.
That's not to say you can't make them work but I think you'll have to do some room treatments at the minimum and a complete gear change at the other extreme.
At the very least I would run them in at a fairly high volume (don't clip!) by facing them very close to each other & throwing a blanket over them. Run one spkr. out of phase so the volume seems muted. After 100 hrs. of this if they still hurt your ears I would look for something else, 'cause at this point your battle is uphill.
