The impedance of the M80s is 4 ohms. The VP150 and QS8s are 6 ohms. This will all be in line soon in all the literature and the speakers. The VP150 and QS8s could technically be called 4 ohm speakers because of the minimum impedance at one small frequency bandwidth but in reality they act like 6 ohm speakers.
