The difference between the LFE channel and the subwoofer output is that the LFE channel is used to carry additional bass information in the Dolby Digital program while the subwoofer output represents how some or all of the bass information will be reproduced.

Is LFE better subwoofer?

Subwoofers are designed purposely for emitting low-frequency sounds. LFE channels transmit the lowest frequencies in audio productions. Thus, when you use the LFE channel on your subwoofer, you get the best low-frequency sound.

What does LFE mean on a subwoofer?

low-frequency effects The low-frequency effects (LFE) channel is a band-limited audio track that is used for reproducing deep and intense low-frequency sounds in the 3–120 Hz frequency range. This track is normally sent to a subwoofer—a loudspeaker designed to reproduce very low frequencies.

Should subwoofer be set to LFE or LFE Main?

LFE – Uses AVR crossover, to pass low frequencies to the subwoofer. Lets say you set them at 80hz, any low frequency than that will be taken care by sub and higher will be handled by speaker. LFE + Main – This will pass all of the bass or low frequencies to the subwoofer, in most of the AVRs the fronts run full range.

Do all subwoofers have LFE?

Almost all AV receivers and pre-amps will feature an LFE (Low Frequency Effects) output. The LFE channel is a mono signal and is already filtered before the signal is sent to the subwoofer. Almost all subwoofers will be equipped with an LFE mode.

Should I use LFE for music?

If you are creating sound effects for film or video games, sending bottom end of your sound effects to the LFE channel is a good idea. It will help you get the most impact out of your effects without muddying up your front, center, and surround channels.

Why do subwoofers have 2 inputs?

Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. If you have a processor with very low output so you can use a Y-splitter. By using both inputs with the same mono signal doubles the subwoofer sensitivity.

Why do some subwoofers have 2 inputs?

Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. If you have a processor with very low output so you can use a Y-splitter. By using both inputs with the same mono signal doubles the subwoofer sensitivity.

What phase should my subwoofer be on?

Typically, though, phase is left at 0° for most applications. While seated in your listening sweet spot, play music with bass content that is familiar to you and then have someone switch the 0/180 phase switch on the sub to 180-degrees. This will let you determine if the bass sounds louder in your seating position.
