Yes it's called expanding foam. Home Depot and All hardware (Ace/True Value) some grocery stores will carry this stuff. One VERY important point is consider what you're planning to fill for there are two types of foam product. One of them is known as minimal expansion the other is known as hi expansion / hi capacity / 3X expanding. I consider the minimal expanding to be fine for what you'll be filling. I DO NOT recommend using the hi expansion stuff because this foam is so strong (expands so much) that I have witnessed windows being forced out of walls during construction of buildings. It sounds like B.S. but others here will verify that this stuff is dangerous. As for the minimal stuff it will be fine.

i don't really know if it is really good for lots of bass, but i used roadkill on my front doors, made a fairly good difference.
