I had a hearing test 1 month ago at a ear nose throat doc. I get one every work anyway. Some upper frequency loss but its been that way for some time.
My system
source is a sony hap-zeis hd player that was around starting in 2014 or
so. No longer made, 7 years old.
preamps, parasound jc2 and also a backert rhumba extreme 1.3
amps parasound a-21 and a jc5.
speakers revel f228be and also have some f208 also.
transparent audio speaker cables.
AQ red river xlr, 2 sets.
I have never conciderd the tweeters could be cooked.
They have failed 3 times on the f208's. Dont know why to this day.
One time at a semi moderate volume. I was there when it happened. Didnt hear anything odd and then suddenly they sounded dead. Is it possable the beryllium
tweeters dont just work or not work like the others that blew ? Like maybe they can be damaged and still make sound?
Anyway i will get some sort of tone testing cd or whatever and try it out.
FWIW my car stereo and my headphones at work dont sound like this.
