LFE + MAIN Settings

In the Speaker Configuration menu, when the speaker channel is set to "Small" the Bass Setting or *Subwoofer Mode menu can be set to LFE or LFE + Main. This will pass all frequencies under the crossover point to the Subwoofer.

For example LFE 120hz - would send all frequencies UNDER 120 to the sub and from 120 up to the speakers.

If the speaker channel is set to "Large" you may want to set the Bass Setting or *Subwoofer Mode set to LFE + MAIN as this setting will duplicate the low frequencies to the Subwoofer. If you set the Bass Setting or *Subwoofer Mode to LFE nothing will output to the Subwoofer with the exception of the LFE from a Dolby or DTS encoded track.

LFE (Low Frequency Effect) - The discrete content sent to the subwoofer from a Dolby or DTS encoded audio track. (The .1 in a 5.1 or 7.1 audio track)

LFE + Main - The low frequencies output to the Subwoofer and speakers whether the speaker channels are set to Large or Small.

SO:  If you have a new speaker - lets say a center speaker and the speaker is rated at 60hz to 20khz then your center should be set to 60hz this way the amp will not send frequencies under 60hz to your center speaker. Only frequencies 60 to 20khz will be sent to the speaker.

If you have a full range large speaker - you would set the amp to FULL range or LFE as low as possible (probably 80hz)

Speaker placements.


There are a few ways to increase or decrease bass in your speakers.


  1. Placement from wall, the closer to a wall and even more so the corner of the walls will give more bass.

  2. Spikes on and off, spikes off will create more bass.

  3. Carpet in the room – carpet helps absorb reflections and thus increasing bass.

  4. Curtains also help with absorbing reflections; open glass windows are something you want to try and avoid.

  5.  Tile / Wood / carpet flooring – these all influence your sound.

  6. Amplifier settings – make sure bass output to BOTH (sub + main) or (LFE + main) is selected otherwise no low frequency bass will be output to the front speakers.

  7. Amplifier settings – When listening to music I always have the amp on PURE or DIRECT or STRAIGHT mode, this means the amplifier will automatically switch to whatever the signal it receives is. In other words, if the amp receives a stereo signal (music) it will only play in stereo, when it receives a DTS signal it will automatically switch to DTS etc..

  8. Make sure your speakers (FRONT) are set to large and full band on the amplifier when you are using floorstanders.

  9. If you have an active sub, then select all speakers to 80hz and let your sub do the low bass by selecting LFE (120hz).
