  Joel CantuAug 29, 2025
  If the sound level from your Yamaha Subwoofer is too low, consider the following: * Ensure that the speaker cables are correctly connected: L (left) to L, R (right) to R, “+” to “+” and “–” to “–.” * Adjust the phase setting to the other position. * If you are playing a source sound with few bass frequencies, play a source sound with bass frequencies, or set the H-CUT to a higher position. * Relocate the subwoofer or change its positioning angle, as standing waves may be influencing the sound.

Why does Yamaha NS-SW901 Subwoofer cause the household breaker to go off?
- C
  Caleb FullerSep 3, 2025
  If the household breaker goes off when using your Yamaha Subwoofer, it could be due to the unit consuming too much electricity when a high-level signal is input. Try turning down the volume on the amplifier connected to the unit, or cut off the power to other unused equipment.
