Measuring and setting the distance

First of All, you need to measure the distance between your sitting position and your speaker. Remember the number.

  • Go to Speaker Settings> Distance> enter the figure.

Secondly, tell your AV receiver the size of your speakers.

size
Adjusting the speaker size
  • Go to Speaker Settings> Size
  • By default, it should be preselected as “small“.
  • But if you have large floor-standing speakers with 8-inch or larger woofers, you may select the size as “large” speakers. But the center and surround speakers may still likely work best run as “small” speakers as this will send any low frequency audio to your LFE channel.

Thirdly, set up the crossover point in order to send the bass away from your speaker and to your sub.

Adjusting Crossover Frequency
  • Go to Speaker Settings> Crossover Frequency
  • By default, it should be 80 Hz.
  • Based on the size of your speaker it can be 60-200 Hz or more.
  • Your speakers’ or subwoofer’s user manual may offer specific guidance in this area. 
  • If you don’t have a manual, try these settings. For small speakers with 2- or 3-inch woofers, try settings between 150 and 200Hz; for midsize speakers with 4- or 5-inch woofers, use 80 or 100Hz; and with large bookshelf speakers or skinny floor-standing speakers, use  60 or 80Hz crossover. 
  • If you have doubts about the speakers’ sizes, always select “small” on the setup menu.

Lastly, adjust the subwoofer volume. To do this,

Adjusting the volume
  • Use a decibel meter or you can also Install decibel meter app in your mobile.
