To the regulars,
I have a rather old subwoofer, purchased a long time ago. Never used it for ages, it was collecting dust in the garage. Had bit of a clear out today, decided to not give the subwoofer away and re use it at home. It's a 12 inch subwoofer with a 300W amp.
When playing something with a frequency below 40hz, the plate amplifier at the back generates a rattling sound, which dominates the bass, making it less clear and it's driving me crazy. Thing weighs around 39kg, so I can't be moving it about ever second just to inspect it. Pressing the amplifier inwards stops this rattling sound. I've tightened the screws holding the amp to the sub, checked for loose components, although I don't think anything loose will create that rattling sound, well except from the toroidal transformer. So what can it be?
I was thinking it could be an air leak between the amplifier and the enclosure, causing the air to leak out. The port, especially at lower frequencies, makes a chuffing sound, indicating that there is a pressure differential. If you're going to ask for a video, I haven't got any.
