Common Issues & Troubleshooting
1. Power issue
Reports have been made that the subwoofer causes problems where it produces loud popping sounds and switches on and off inconsistently and constantly without an input signal.
This may mean that there is an issue within the amplifier itself.
Solution: Carry out a “buzz test” on the amplifier. Turn on the subwoofer and set the gain knob to between 50-60%. Touch the male RCA post (not connected to the receiver) to see if there is any buzzing. If sound is absent, then the amplifier needs repair or replacement.

2. Absence of Input With a Low-Level Hum
Usually, a faint hum of sound at the time of no input can occur, which is often caused due to grounding fixations.
Solution: Check all components to ensure that they are set to the correct ground. You may try to use a different socket, which is on a different circuit from where the subwoofer was initially plugged in. Electric noise can also be greatly reduced by the use of a power conditioner.
3. Bass Being Boomy or Unclear
Users have reported that the subwoofer can sound abnormally loud or unclear, especially in certain acoustically designed rooms.
Solution: Change the low-pass crossover + phase controls and change the subwoofer’s placement to achieve the optimal settings needed for the room. This also helps in placing the subwoofer away from corners and walls, and the boominess can be eliminated.
