I just bought a pair of these for $100.
But they seem to have an issue.
If there is a song with a bass, the woofer gives some kind of distortion. It goes with the music. I have the speakers for a week and there were 2 days where I thought the distortion was gone. But now i hear it again. I know for sure that the problem lays with the speakers. One of the pair doesn't have it (that bad). If i put my finger on top of the cone, the distortion is a lot less. I also live on the second floor, and my house is made out of wood, so maybe its the vibration? I don't know.

I opened it and the electronics seems fine. It's like new in there.
The woofers and tweeters of both speakers moves manually but they make a scrape noise when you do it. When i find a good spot, it does not make that scrape noise.

Also the distortion does not go up with the volume. I can only hear it when the volume is low.

Is it common that speaker have this kind of distortion over the years?

Maybe someone can help.

Thanks

Bass drivers are called woofers. The small, high frequency drivers are tweeters.

Wood structure of the house is not related.

Rotate the woofers 180 degrees and see if the helps to straighten them out. I'm not familiar with your exact model, but overtime the woofer and spider begin to sag. It's worked for me a number of times and it's easy to do

Wow! I could only turn it 90 degrees because the cables aren't long enough but i think it already helped a lot. Now the bad one sounds like the other (less bad) one. That's a big improvement! Thank dude, i give you the trophy 'Clever Badass'

You can just flip the whole speaker to test this.
