In series
Two identical subwoofers with one voice coil (single voice coil) or one
subwoofer with dual voice coil are connected in series.
Note: The connection of two voice coils in series will result in doubling
the impedance!
Maximum output power of this configuration:
Two subwoofers with 1 x 2 Ohms correspond to a total impedance of
4 Ohms: 525 / 1,050 Watts
Two subwoofers with
a single voice coil
One subwoofer with 2 x 2 Ohms also corresponds to a total impedance
of 4 Ohms: 525 / 1,050 Watts
Two subwoofers with 1 x 1 Ohm correspond to a total impedance of
2 Ohms: 830 / 1,660 Watts
One subwoofer with 2 x 1 Ohm also corresponds to a total impedance of
2 Ohms: 830 / 1,660 Watts
Note: The connection of subwoofers with 4 Ohms in series is not recom-
mended because it results in a low output power of the amplifier!
One subwoofer with
a dual voice coil
