Please do not waste your time explaining impedance to me. I have read all kinds of explanations and still do not understand it. But my question is a simple one: I have a Sunn 200s amp but getting too old to lug the 215 cab around and am not good enough to merit a roadie. Can I plug my 2 lightweight GK cabs (115 and 210) into the 200s without doing harm? My taps are not marked so I do not know what impedance they are. Have read that they could be an 8 ohm and a 4 ohm, but have also read that they could be an 8 ohm and a 16 ohm. Thanks in advance for a hopefully simple answer.
