Subwoofer strange noise

I have a less than year old B&W ASW300 Sub. I just moved it to another part of my audio room closer to where I sit and the sound has improved dramatically. However, I am hearing a "clicking" or "knocking" coming from the internal woofer at each beat when the unit is being driven, not excessively but at a decent volume level. It almost sounds like it has a tear in the cone material but it doesn't. I've looked very closely and there are no defects that I can see. Is this normal? This is my very first SW and don't know if this is a normal sound or not. Can anyone guide me on this? Does this sound like a defect in manufacturing? Thanks.

You may need to pull the driver and play it while it's out of the box to get a better idea on whats going on.

Sounds like it is being overdriven to me. This is a very small low powered sub. Good luck.

Try tightening all the screws and bolts you can get to from the outside first. Check the port to be sure there isn't something in there.

Unless you see something from the outside it is going to need to be taken apart. Something has come loose inside (amp? bracing?) or the speaker is coming apart or rubbing.
