My DF-10 sub is leaking glasswool from the bottom port !! Yesterday my maid found a few bits of glasswool on the floor which she threw away. Today there was a larger quantity (bigger than a fist), which was lying around the sub. Should I be worried about this? For the time being I've pushed it back in the port, but is it supposed to leak like this? I've not overpowered the sub at any time. All times my receiver is playing movies is around -9.0/-10.0 dB. Only at times have i increased the volume to around -6.0 dB.
I am a bit scared - thankfully it's still in warranty as it's purchased only 2-3 months back. I'm planning to write to them about this and see what their response is.
