아 뉴에그 후기였군요. 딱 아래와 같은 증상 나오고 해결책은 딱히 없습니다.
리시버는 야마하 어벤티지예요.

Pros: Overall sound quality good. Newegg handled the return of these speakers with no problems.

Cons: Internal vibration/rattle from mid-range enclosure. Ugly cabinet design.

Other Thoughts: These speakers had an overall sound quality that was very good. Bass response was good, but there in lied the problem. If you have a receiver that can produce a good amount of bass, both speakers had a vibration and/or rattle coming from the mid range area of the cabinet. JBL states the mid-range speaker has it\'s own enclosure inside the cabinet, and I believe there in lies the problem. If you push a lot of bass from these, that enclosure has some resonance to it. At first I thought something was vibrating on the stand next to the speakers, but I then realized it was coming from the speaker itself. Might not be an issue if your receiver can\'t push much bass, such as a Yamaha, but with the Onkyo I had these hooked to, it was a real annoyance. Had to return the pair and newegg was very good with the return process. I\'ll stick with Polk in the future.
