If your tweeters are really absolutely silent you'd have a very "muddy" sounding speaker, the tweeters carry most of the music, not just "crisp" high frequency information. It's doubtful they'd both be really "dead" in my opinion. Don't know your age but if you're in your 50's/60's it could be a rolling off of your hearing, mine's diminished in the high frequency area, I'm 63.
Have a friend carefully cup the tweeter while its playing, you should hear a difference. When working correctly, they're not supposed to be "bright" or even "crisp", just smooth and easy on the ear btw.
