Yamaha hs80 problem

Ok this morning I bought this pair of monitors.
Installed them and seems one of them has some kind of distortion going on at low levels on the tweeter, the more I turn up the volume I notice the distortion goes away but I can hear more high end.
While the other is smoother (a tiny bit less of high end) and doesn't have any kind of distortion.
You can barely hear the distortion, I know if I take them back to the shop will tell me I'm crazy lol
I think I'm gonna record the speaker so you can hear that yourselves.
Did you ever hear something bad about yamaha manufaturing especially on hs80's?

cheers guys
 
Make sure to check the cable you're using. Sounds like it may be a blown tweeter, though. Had a similar problem with my BX8a, but replacing the tweeter only cost about 15 bucks.
