It's a matter of taste, but if you were my friend I would gently suggest that this is a great excuse to get some better-sounding speakers.
The deaftech speakers all have a harshness to their treble that drives me up the wall; a sure recipe for listener fatigue, IMO.
Speakers that sound very good to many people include PSB, Monitor Audio, KEF and B & W. They have much better-sounding tweeters, plus outstanding overall performance.
If you really want to keep what you have you should get a new tweeter from the manufacturer and replace it; it cannot be repaired. There is no way to restore it to its original shape and rigidity once it has been deformed, which would be essential to restoring its original performance. Any thought of repair is nonsense.

What could cause this? My speakers are calibrated to 75dbs at -10 volume on my Denon 791 AVR and I have my receiver set to never go louder than -10.
