■ Subwoofer Parallel-connection
The subwoofer AX15W features four input/parallel connectors—two 1/4” phone jacks and two Neutrik NL4MP
connectors. Use either a phone jack or a Neutrik connector to receive input from your sound system/power ampli-
fier. One of the spare connectors can be used to parallel-connect an additional main speaker (keeping in mind the
impedance considerations mentioned below).

■ Impedance Considerations
When connecting speakers in parallel be sure to check the rated load impedance of the power amplifier. Most power
amplifiers are capable of safely driving speakers with minimum impedance of 8 ohms or 4 ohms. A pair of parallel-
connected 8-ohm speakers have a total impedance of 4 ohms. The AX10/AX12/AX15/AX12M/AX15M are 8-ohm
speakers, and two of these can safely be paralleled on one output. Two or more speakers can be connected in paral-
lel, however, if you are using a power amplifier that can safely drive load impedances of 4 ohms or lower.
