It also helps eliminate standing waves, which is something like an echo inside the box. This will give you tighter and more accurate bass. It also helps to give a flatter frequency response to the overall sound, which is good. Besides this, it also helps reduce the vibration of the box, which results in less distortion. There is a big difference to the bass when you have an insulated box. Damping also increases subwoofer efficiency by dissipating some energy that affects the sub, particularly the voice coil. It is advisable to put damping material inside a box. Pillow polyfill and fiberglass insulation are common, though polyfill is a lot easier on your skin. Polyfill also "tricks" a sub into thinking it is in a bigger box. Most sealed and vented enclosures require 1/2 lb. of dampening material per cubic foot of internal enclosure space. For best results it is recommended to loosely fill the material throughout the enclosure.

Use contact cement for the felt. Don't make the layers bonded tightly to each other, but rather just losely against each other. Plywood with triple felt lining. Use contact cement for the felt.

Speakers make sound from vibration (both forward and back). That means as much sound travels into the box as does out into the room. If your wood is too thin, or you're speakers aren't flushly mounted, you're probably getting a secondary sound from the box itself. It could also be from vibration from a bad mount. Wood is typical.
