FAQs

What is the power output of the Kanto SUB8?

The Kanto SUB8 delivers 250W of peak power using a Class D amplifier.

What size is the speaker driver?

Can I connect this subwoofer wirelessly?

No, the Kanto SUB8 requires a wired connection using RCA cables. It does not have built-in wireless capabilities.

How do I adjust the crossover frequency?

The subwoofer has a built-in precision low-pass filter (LPF) with a dial that allows you to adjust the cutoff frequency typically between 40 Hz and 120 Hz to match your main speakers.

What does the phase switch do?

The phase switch (0° or 180°) helps synchronize the subwoofer's output with your main speakers. Flipping the switch can improve bass integration and impact depending on your listening position and room acoustics.

Does it have an auto-off feature?

Yes, the SUB8 features a power-saving auto-off function that puts the subwoofer into standby mode when no audio signal is detected for a period.

What material is the cabinet made of?

The cabinet is constructed from acoustic-grade MDF to minimize unwanted resonance and enhance sound clarity.

What cables are included with the subwoofer?

Troubleshooting

No sound from the subwoofer

Check that the subwoofer is plugged in and the power switch is on. Verify that the volume is turned up and the audio source is active. Ensure the RCA cable is securely connected to both the subwoofer and the audio source.

Humming or buzzing noise

Try a different RCA cable. Ensure all audio components are plugged into the same power strip or circuit to minimize ground loop noise. Adjust the subwoofer's position; sometimes proximity to other electronics can cause interference.

Weak or muddy bass

Adjust the LPF (Low-Pass Filter) and Phase settings. Experiment with the subwoofer's placement in the room. Try moving it closer to a wall or corner to boost bass, or further out if it sounds boomy. Ensure the volume is set appropriately.

Subwoofer doesn't turn on automatically

Confirm the power cable is securely connected. Check if the 'Auto-Off' feature is engaged and ensure the audio source is sending a strong enough signal. The auto-off feature requires a sufficient audio input to activate.

Setup, Compatibility & Care

Setup:

  1. Connect the subwoofer to your audio source (AV receiver, soundbar, or speaker system) using an RCA cable to the 'Line In' port.
  2. Power the subwoofer using the included AC cable.
  3. Adjust the Volume knob to your desired level.
  4. Set the Low-Pass Filter (LPF) knob to match the frequency range of your main speakers. A good starting point is often around 80 Hz, but consult your speaker's specifications.
  5. Use the Phase switch (0° or 180°) to determine which setting produces the most bass impact at your listening position.

Compatibility:

The SUB8 is compatible with any audio system featuring line-level RCA outputs. It works well with AV receivers, integrated amplifiers, powered speakers, and soundbars that offer subwoofer pre-outs or line outputs. Ensure your audio source has a way to output a low-frequency signal.

Care:

  • Clean the exterior with a soft, dry or slightly damp cloth. Avoid abrasive cleaners.
  • Ensure the vents are clear of dust and obstructions.
  • Regularly check cable connections to ensure they are secure.
