Troubleshooting Your Subwoofer

Created: Jul 17 2018 | Updated: Aug 24 2018

No Output

• Check that all components are plugged in and turned on.
• Check all interconnecting cables.
• Check that the subwoofer is connected to the sub out (or other appropriate output) on the receiver/processor/amplifier.
• Check that subwoofer output is enabled in the receiver/processor's setup menu.
• Make sure the sub's level control is not turned down.
• If the problem persists, contact your dealer.

Muddy Bass

• Check placement. Try moving the subwoofer closer to the front and side walls.
• Check the type of feet that are being used. If available, try installing the ETC spikes.
• Decrease the volume level.
• Check your processor setup.
• If the problem persists, contact your dealer.

Hums or Unusual Sounds

• Turn the subwoofer off, unplug all signal inputs, turn the subwoofer back on and turn up the level. If the problem disappears, the hum is originating elsewhere in your system.
• Connect the sub to the same AC circuit as the receiver/processor.
• If operating in wireless mode, move the sub away from microwave ovens and/or any devices that use wireless technology.
• If the problem persists, contact your dealer.
