[QUOTE="squeak9798, post: 836913, member: 555320"] It's sound absorbant material, designed to deflect the rearwave of the speaker to reduce standing waves and cone breakup. That, or deflex pads, are supposed to make a pretty noticeable difference. While I haven't installed any yet, I've read enough about them from IASCA world champions to trust their opinion that they do infact work [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Plus, for the $20 or whatever, you're not out much if it doesn't [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] If you are building sealed doorpods, I wouldn't worry so much about this. It may still help reduce road noise some though. However, if the back of the pod is going to be open into the door (for IB), then covering the holes in the panel is a MUST. [/QUOTE]
