Actually, a 12-inch speaker is really a 9-inch speaker for the purposes of moving air because the diameter of the moving diaphragm is only 9-inches. Therefore, measuring to the outside of a speakers basket might be good for designating speaker size, but it is not the correct measurement to use for calculating SPL. That's all I'm saying.
Consequently, I would need to see the algorithm in the SPL calculator in order to understand how it works and which speaker size designation to use.
