Two subwoofers with
a single voice coil
One subwoofer with
a dual voice coil
In series
Two 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 re-
sult in doubling the impedance!
RMS output power ≤ 1% THD+N:
Two subwoofers with 1 x 2 Ohms correspond to a total
impedance of 4 Ohms:
One subwoofer with 2 x 2 Ohms also corresponds to a
total impedance of 4 Ohms:
Two subwoofers with 1 x 1 Ohm correspond to a total
impedance of 2 Ohms:
One subwoofer with 2 x 1 Ohm also corresponds to a
total impedance of 2 Ohms:
Note: The negative terminal of the first voice coil has to
be connected to the positive terminal of the second voice
coil by using a speaker wire with the same gauge as the
other speaker.
