Here is another thing to think about in terms of cone area. Lets look at a piston in a engine. Does the shape of a piston change the bore size?
But like said already the whole cancellation aspect is huge, not to mention the strength advantage, lighter moving mass, less turbulence on and round the sub, and the ability to do some extra tricks with the soft parts not possible with a paper cone. Oh did i mention it looks 10x better then a paper cone?
I will do a bit better testing with this prototype when i get home and can put some real power to it. Maybe even try it out in a 180+ extreme vehicle to see whats louder, how does that sound? Han? :dj:
