Following some research on acoustic resonances, it was brought to my attention that the enclosure air-spring becomes non-linear beyond a certain level of compression. Therefore the Maximum SPL (below an arbitrary distortion threshold) attainable by a system is thus dictated by the volume of air within the enclosure.
Dennis H has provided a useful formula for determining distortion relating to air compression:
Distortion % = 140*(one-way driver displacement)*(1/enclosure volume)
What are the causes for this form of distortion? Is it due to the temperature decay or the pressure imbalance between sides of the diaphragm?
How can we decrease this phenomenon?
Thanks,
Thadman
