Illuminati (33rd Degree)

Here's a chart that will help quantify matters. Below is an SPL chart based on Fostex specs. Add 6dB for π/2 radiation, where applicable. I've included maximum output based on the 10log figure, which of course assumes that X-max is not an issue and that there is no compression. In other words, the maximum SPL listed here is rather optimistic.
