QSC Audio 1700, 1100, 1400, 1200 Cable, Power Loss, Damping, Length, Gauge, Resistance, Factor

loss of 10% is barely audible, the resultant low damping factor will prevent the amplifier from fully controlling the peaks and dips in frequency response caused by speaker impedance variations. This will result in greater coloration and muddiness.
