As a tweak or upgrade, has anyone ever changed out the acoustic foam in their subwoofer or speakers? Or does it really matter what type of dampening material you use or its density, especially in a sub? I'm more interested in real world results as opposed to theory and what the "experts" say about it.
The acoustic foam that came with my Dayton Titanic kit was of much higher quality than the foam I installed in my main sub. Just wondering if this foam is worth switching out and if so, what benefit I can expect.
