I think that I had a problem with vinyl rumble, has anyone else experienced this?
The system I using is a stereo setup with a pair of B&W 601's hooked up to a Denon AV-2802 amp. The record player has a Linn Sondek arm.
My speaker's woofer cones were going crazy when I played a remix of "Air - Surfing On A Rocket" on my record player. They were vibrating in and out around 2cm. These are only small woofers, less than 5 inches diameter, and I'd never seen them moving so much. This wasn't even at a particularly loud moment in the track, and the volume wasn't that high either. I just assumed though that it was something odd with the music.
The next day, my dad put on a work by George Gershwin, and the same thing happened. This time the cones were going even crazier, and their movement did not correlate with the music. I then remembered that my old Pioneer amp had a subsonic filter, which was there to remove record rumble. Seeing as the Pioneer dated from the 70's and wasn't entirely reliable, I decided to do a workaround. This involved changing the speaker setting on the amp to "small", thus removing the problematic frequencies.
I am concerned though that the speakers might be damaged.
