[QUOTE="bose301s, post: 4533808, member: 575773"] No, no Fourier transforms, no Fourier series, I just got done with that stuff!! Fourier stuff is hard, it's hard to think in the frequency domain, much easier to think in the time domain. As for mass, you are correct, what is much more important is stiffness of the cone. You can have 2 identical mass cones, one that is super stiff and one that isn't. The softer one will cause frequency smearing as well as standing waves on the cone. It also lowers the radiating area as the center will move with the VC but the edge will stay much more stationary. This effect is actually used to the designers advantage in phase plug drivers, since the middle is has much quicker transient response and can reproduce high frequencies it is used as a tweeter basically. The driver however directs the sound into the center of the cone, with the phase plug it hits the plug and deflects on a path to the listening area. [/QUOTE]
