Default What is causing this sound and some other questions...

Hello,
Can anyone tell me what is causing this sound?
YouTube

Is this spider hitting the bottom?
The reason I am asking is because I would like to change the magnet and coil to bigger (I would go from 30w to 100w -just for fun), but I don`t know what is causing this sound when I overpower the woofer.

I would also like to know if I can get T/S info (to build L port box) by measuring the original ported box.

Thank you for help

That sound can be caused by multiple causes, the voice coil hitting the back plate being another one which damages the woofer quite fast. T/S parameters you could measure youself, you can find how to using a search engine.
