@Miiksu I believe the super hard plastic and the grill are causing the hollow sound. The black foam helps cover the plastic and the cotton keeps the sound in control, so I am VERY happy with the back end. The front still needs work. As far as the grey foam baffles I made, I do not think it helps much. I can't hear any difference with it on or off. Taming the treble without losing the wonderful clarity is the next challenge.
I am able to listen to the song "Hail to the King" that
@Hal Rockwell mentioned without my ears bleeding.
Also I need to change the name. Walmart mod isn't very good, I think something like "The Wolfhammer Mod" is much more descriptive
