= Equivalent air compliance The volume of air that has the same compliance ("springiness") as the driver's suspension Because less air is more "springy" than more air, a large Vas represents a "loose" suspension
Compliance A measurement in liters or cubic feet of the volume of air that is equal to the compliance of the speaker's total suspension
Visual Analogue Scale, a scale in which a patient marks a point on a line between two points to indicate how much of a certain symptom, such as pain, he or she feels
Volume of air having the same compliance as the driver suspension The compliance, or stiffness, of the driver suspension is determined by the surround and the spider This parameter is measured in cubic feet
The equivalent volume of compliance, which specifies a volume of air having the same compliance as the suspension system of a driver
