1. Firstly, fix the supplied feet to the subwoofer cabinet using the included screws.
2. Using high quality interconnects, connect the SX-120 subwoofer line-input to either the sub-out, or pre-out of your amplifier or receiver.
3. As low frequency content is largely non-directional you can position the subwoofer almost anywhere within the room.
4. Connect the mains power cable to the AC power socket, and power on the unit.
5. Adjust the crossover frequency, phase settings, and volume to suit your setup.
