I have a ML200 2X10 combo that I have been running bridged (200 watts) since I got it and am totally happy the way it is. I just finished reading the manual about the switchable feature and running 2 - 4 ohm cabinets at 100 watts each. This is actually pretty cool because I have an SWR Goliath 2X10 cab (4 ohm) to plug in if I ever want to go that way. My question: If I plug my SWR into one of the 4 ohm outputs and the combo cabinet (8 ohms) into the other 4 ohm output, How much horsepower (watts) are the combos 2X10 speakers actually receiving? At what % of efficency would the 8 ohm cab be operating? Did I word that right?
