I hope it is OK if I ask this here, as search engine brought me here. Do all these factors also apply to the foundation mounts for high end car audio woofers? Specifically, which is a better material for mounting 6.5" Focal Utopia woofers, mdf, wood, or aluminum? Or does it simply not matter for a cylinder shape in the same way it does for a closed cabinet? If I use CDT aluminum car speaker mounts, cnc'd specifically for my car, anything wrong with lining the inside of the cylinder with 1/8" closed cell foam? thank you in advance.
