One subwoofer with
a dual voice coil
24
Mono subwoofer application
Subwoofer with one voice coil (single voice coil)
Maximum output power of this configuration:
1 x 4 Ohms: 525 / 1,050 Watts
1 x 2 Ohms: 830 / 1,660 Watts
1 x 1 Ohm: 1,100 / 2,200 Watts
Filter settings
Bandpass, high- and lowpass filter
Bandpass Highpass filter
(BPF) 100 Hz
Parallel operation
Two identical subwoofers with one voice coil (single voice coil) or one
subwoofer with dual voice coil are connected in parallel.
Note: The parallel connection of two voice coils will result in halving the
impedance!
Maximum output power of this configuration:
Two subwoofers with 1 x 4 Ohms correspond to a total impedance of
2 Ohms: 830 / 1,660 Watts
One subwoofer with 2 x 4 Ohms also corresponds to a total impedance
of 2 Ohms: 830 / 1,660 Watts
Two subwoofers with 1 x 2 Ohms correspond to a total impedance of
1 Ohm: 1,100 / 2,200 Watts
One subwoofer with 2 x 2 Ohms also corresponds to a total impedance
of 1 Ohm: 1,100 / 2,200 Watts
Note: The parallel connection of 1 Ohm voice coils will result in shut-
down of the amplifier.
