I can't help but notice that manufacturer are still using paper cone subwoofers, while other companies are using aulumium, carbon, poly cones etc. etc. What is the purpose for having paper around? You would think having paper in the automotive enviroment would be a bad idea, considering things like moist/ Uv rays. For example most factory speakers found in cars are paper,over a period of time they become dry-rotted or cracked, in other words wheather beaten.
