Do you have a multimeter? Measure the DC resistance of you speaker load, i.e., set the speaker to measure ohms. This measurement is always lower than the nominal AC impdance. For example a speaker that measures 6 ohms DC is an 8 ohm speaker. A 4 ohm speaker will measure 3 ohms DC; a 16 ohm speaker will mesure around 12 ohm.s

It works for speakers hooked up in parallel or in series as well.

I need to call up Behringer to find out what one of their techs say.
