Hi,

I bought a pair of DB651 speakers along with pioneer DEH-P5050UB head unit. The speakers worked very well for 6 months.

Now recently the sound quality has deterioted. These is some extra vibration when a rock music is played. When I got it checked with the dealer, he observed the problem and replaced it with a new set of DB651.

Any body knows what could be the issue ?

Thanks,
Johny
