5 Set the HIGH CUT switch to the LOW or HIGH position.
This subwoofer is designed so that the optimum tone balance between the subwoofer and the main speakers is obtained when this switch is set to the LOW position. The tone balance may change, however, depending on the room size, the distance from the subwoofer to the main speakers, and so on. If necessary, switch it to the HIGH position.
Frequency characteristicsFig. 1 shows the frequency characteristics of the subwoofer with each position (HIGH/LOW) of the HIGH CUT switch.

6 Increase the volume gradually to adjust the volume balance between the subwoofer and the main speakers.
Normally, set the control to the level where you can obtain a little more bass effect than when this unit is not used. If the desired response cannot be obtained, adjust the HIGH CUT switch and the VOLUME control again.
●Once the volume balance between the subwoofer and the main speakers is adjusted, you can adjust the volume of your whole sound system by using the amplifier’s volume control.
However, if you change the main speakers
●For adjusting the VOLUME control and the HIGH CUT switch, refer to “Frequency characteristics” below.
Fig. 2 shows the optimum volume level with the HIGH CUT switch at the HIGH position, and the frequency characteristics when the subwoofer is combined with NX- 230P.
