Default What is oil can popping of a sub

I was comparing Dayton HF and Ho series 12 inches. I hear HF is meant for large enclosure and that in a small enclosure it can have the issue 'cone is prone to 'oil can popping' in high Q/smaller enclosures'

It turns out the in a 35 litre 1.255 cubic the HF still looks better than HO

What is this oil can popping?

Yellow is HF in 78 litres
Blue is HF in 35 litre, thats my car sub enclosure size
pink is HO

Where i found this oil can pop issue

The Dayton Ref line has an aluminum cone. I'm
Guessing it has something to do with the cone ringing or making a popping noise?
