Question about Polk Audio RT1000I Speaker
One of my speakers developed a loud hum on the powered subwoofer side of the speaker. When I first noticed the hum I could tap on the amp and it would go away. But after turning my hometheatre amp on it would come back. This went on for about 15 minutes. Now the hum is gone but there is no sound coming out of the sub. The fuse is ok on the amp but I don't hear the speaker "click" on like the right speaker does. The front LED is still on so I know that it is getting power. Is my amp fried? Or is it the sub speaker itself? I also tried using both the "rca" inputs and the "speaker in" inputs and nothing changed. Polk Audio wants $200 for a new replacement amp. The rest of the speaker works fine. Any help or suggestions would greatly be appreciated.
Try another speaker on that channel if you get no sound or it hums then it is time to take your set to a tech your audio out put on that side is damage along with some caps.good luck.
