exactly, 3dB less!
Have you already built a SB18 test cab to compare with the ES-18BPH?

I should be building (well glueing together) the beyma cab in the next couple of weeks, going to load it with a void v-18 1200.
I'll post measurements when i'm done but I can't measure absolute SPLs

 black = 2x SB15 - PAudio SN15LF (2Pi, 1W/2.00V)
grey = ES-18BPH - PAudio C-18ELF (2Pi, 1W/2.83V)

bitzo, driver displacement is not subtracted from vtc, I expected that the driver is fireing into the chamber and reverse mounted so that the magnet extends into the horn/port...
