There are actually many factors that come into play when you are looking at the ability of the woofer to maintain control during bass reproduction at high volume. The mass of the cone is only one factor and in fact aluminum is not, in most instances, heavier than other cone materials, but it does have a better stiffness to mass ratio. Another very important factor to consider when trying to achieve clean reproduction of low frequencies at high volume is the motor control of the voice coil. Regardless of the cone material if the combination of the cone travel, voice coil length, and BL in the top plate gap are not sufficient to maintain control of the woofer the bass performance at higher volume levels will get very ugly. Thus in the design of the woofer itself we need to consider all of the factors surrounding bass distortion at high volume. This is an area where we have spent much time researching.
