Question on speaker quality

[Shannon]

I'm currently using a logitech z3e 2.1 set that is about 4 or perhaps 5 years old. It seems to still do it's trick. Also don't worry about the buzzing, just as long as it doesn't crackle or you're able to hear a scattered electronic sounding voice you're fine.

I don't think that a speaker wears out in the same way for example a car motor would lessen in horse power or your hearing ability would lessen once you get older. But still, perhaps Shannon can prove me wrong one's again

Hearing do get worse when you get older, or when you play extreme high music as i have done. :L
In any case, what you mean with Crackle?
My speakers makes the sounds like "krechshsrkrkshkrhk" on some sounds sometimes when listening to things.

Does it crackle only on ultrasonic subliminal, only on regular music, or on both? If it's crackling on ultrasonics only, you have to read the instructions that came with it for what to do.
