A few years ago after a visit from my young grandson-5 years old- I found my tweeters had been modified.
I took my eye off the ball for this one. He’s a lovely lad of 11 now. I’ve never mentioned it to him and he obviously doesn’t remember.
I do get some distortion and certain records I don’t play cos of it.
Recent price to replace £160 + £38/hour labour to replace. I’m not going to bother.
Remember if you have grandchildren they’ll probably move faster than you.
