The frequency response curve clearly shows the low frequency extension of the
V 70 SE linear to 10 Hz The loss at 20 Hz is less than 0,2 dB

Hz
Noise spectrum at 1 kHz / 5 W into 4 ohm – there is no mains interference to be seen.
(50 Hz < 200 µV, 100 Hz < 70 µV) The k2, k3, k4 and k5 noise spectrum is extremely
low and falls quickly.
