Input Impedance Avalanche IQ Subwoofer Amps

The input impedance on our current 1961 and 1723 subwoofers is 20kOhm, except when the lowest gain setting is used.
In that case, it is 13kOhm (13.333kOhm to be precise) because of an attenuator added to the input signal path. With our very customizable gain structure, it is very easy to match it with any setup.
