the box Speaker 12-280/8-W

I had to return the first of this speakers immediately, as it was poorly manufactured. Of of the box, there was scrapping noise, even at very low volume, sounded like a badly centered voice coil. The second one
has similar symptoms, but noise is much quieter here. As I ran out of time, I could not return this one. Up to now it is working (small bass reflex sub for two 8" satellites) fine. But time will tell, if this is really as sturdy and relieble as a 12" sub should be. @Thomann: make this speaker more expensive and invest in better quality assurance.
