What's The Maximum Sound Pressure Level?

That's quite easy to calculate for closed cabinet or bass reflex loudspeakers.

This is an example of two Alcone AC12/SW8: however, the parameters of any other driver may be entered. The values are valid for an optimally tuned bass, under the condition that it can handle the power. Therefore, we calculating the maximum sound pressure level based on the excursion of the bass driver.

This is an approximate calculation.
