8 Hz. That’s your frequency target for those Telarc 1812 cannon shots. Your system needs to be able to survive high power at 8 Hz.
What sort of SPL would be "realistic"?
According to the US Army, the impulse SPL of a 105 mm howitzer at the gunner’s location is 183 decibels. That’s roughly one BILLION times the sound power of the 92 dB target mentioned. Obviously this isn’t practical for a home audio sound system, but I wanted to give some perspective on the difference between 92 dB and "realistic".
The amount of air displacement it would take to deliver even 92 dB @ 8 Hz at the listening position is enormous. You’d be looking at something like 2 or 3 very capable 15" subwoofers.
