Examples for speaker configurations
Parallel operation
Two 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!
RMS output power ≤ 1% THD+N:
Two subwoofers with 1 x 4 Ohms
correspond to a total
impedance of 2 Ohms:
1 x 700 Watt
One subwoofer with 2 x 4 Ohms
also corresponds to a
total impedance of 2 Ohms:
1 x 700 Watt
Two subwoofers with 1 x 2 Ohms
correspond to a total
impedance of 1 Ohm:
1 x 1
,030 Watt
One subwoofer with 2 x 2 Ohms
also corresponds to a
total impedance of 1 Ohm:
1 x 1
,030 Watt
Note:
The parallel connection of 1 Ohm voice coils will
result in shutdown of the amplifier.
