This applies to the following Rumblewood Subwoofers


Your Rumblewood Subwoofer has a set of controls that are useful to understand including…

  • Low Pass Gain
  • Low Pass Frequency
  • Phase Switch
  • EQ Frequency
  • EQ Bandwidth
  • EQ Level

The Low Pass Gain is basically a volume control for your Rumblewood Subwoofer.  Turn this higher for more bass and turn this lower for less bass.

The Low Pass Frequency determines the highest frequency your Rumblewood Subwoofer will attempt to play.  If your other speakers have strong bass, setting this lower is often better and if your other speakers have weak bass, setting this higher is often better.  If this is set too low, the bass may feel thin or weak.  If this is set too high, the bass may feel muddled or boomy.

The Phase Switch allows toggling the Rumblewood Subwoofer between in phase and out of phase.  This is most relevant if you have a second subwoofer or your other speakers have significant bass.  Experiment with this to find the best setting.

The EQ Frequency, EQ Bandwidth, and EQ Level allow manually adjusting up/down a specific frequency on the Rumblewood Subwoofer normally to address a specific issue.  Normally leave the EQ Level at 0 unless you know you need to manually adjust the response of the Rumblewood Subwoofer.

You can find additional details in the Dayton Audio plate amplifier manuals here…


If your audio receiver supports auto-calibration, we strongly recommend you auto-calibrate your audio system as follows…

  1. Connect your Rumblewood Subwoofer to your audio system
  2. Position your Rumblewood Subwoofer at the expected position in your room
  3. Set the Low Pass Gain on your Rumblewood Subwoofer to a reasonable level
  4. Set the Low Pass Frequency on the Rumblewood Subwoofer to the highest value (your receiver will effectively determine an appropriate cutoff)
  5. Set the EQ Level on you Rumblewood Subwoofer to 0
  6. Run auto-calibration on your audio receiver (normally involves connecting a microphone and letting the receiver play specific audio signals to all your speakers)
