the details on MF are wrong. the 115MBE will be available in a 400 watt/8 ohm version.
similarly, the 212MBE is also available in a 600 watt/8 ohm version.
look at the GK website. they have the correct descriptions there.
On the GK webpage, it says 400 watts, 8 ohms for the 115.
On the GK spec sheet from the GK webpage, it says 200 watts, 8 ohms.

And then MF says 200 watts, 4 ohms.
If I had to guess without knowing anything, I would guess that the speakers they put in the combos would be the same speakers they put in the extension cabs. So the 210 combo has 2 - 200 watt speakers and the extension would be the same, so an 8 ohm load and 400 watts total.... which is what the GK specs say. Which matches up with the 350 watt at 8 ohms amp in that combo. The 212 combo would have 2-300 watt speakers, for 600 watts total. Which matches up with the 500 watts at 4 ohms the combo is rated for.
The MB115 amp is putting out 200 watts, so I would have guessed for a speaker that is rated at 250. If they really are putting in a speaker which can handle 400 watts at 8 ohms, its probably not the same speaker in the MB115 combo.
First crush, then, when you suggest you all turn down, they behave better. IMO.
