LFE: This stands for Low Frequency Effect and is the dedicated “. 1” channel in a 5.1 or 7.1 surround mix… Both or LFE+Main: Most systems have a mode whereby the bass frequencies below the AV receiver's crossover point are sent to both the subwoofer and the main speakers.

The subwoofer outputs the LFE channel plus the lower frequencies of the full range channels. The crossover frequency is the where the AVR sends the lower frequencies of the regular channels to the subwoofer. All frequencies under 120 kHz are non-directional by human perception.

When using an LFE/subwoofer cutoff (-3dB) at 80Hz / 24dB/octave slope, the frequencies slightly above the 80Hz setting are high enough to still have directional perception, especially if the sub is located in close proximity to the listening position.

Large Vs Small (LFE + Main, Double Bass, etc…) Small applies a 12 dB/octave high pass to the speaker at the selected crossover frequency. Small sends a duplicate signal to the subwoofer and applies a 24 dB/octave low pass to the subwoofer at the selected... LFE means the subwoofer gets the LFE ...

It sends all the low frequency sounds to the sub and every sound over 80 hz to the speakers. I also set the LFE to 80 Hz with my Audigy 2 and Inspire 5.1 speakers even though its not a true LFE. It...

The crossover determines the level the content that will be filtered from the speakers to the sub. It applies to both movies and music and can generally be set individually for all speakers. Personally I currently have my crossover setting at 110 Hz. Lowering it much beyond this creates a more choppy frequency response as I've measured using REW.

The crossover frequency is the sound frequency point at which sounds after that will be greatly reduced, effectively blocking them. We use it as a reference point at which the output to a speaker (or the input to an amplifier, when using active crossovers) is reduced by 3 decibels (-3dB).

The crossover frequency of your subwoofer is the frequency at which your speakers start to roll off and your subwoofer kicks in with LFEs and bass notes. Most modern AV receivers feature an auto EQ program that will assign the proper crossover frequency automatically based on the capabilities of your loudspeakers.

The LPF is the cut-off frequency for LFE content, but the LFE and LFE+Main setting controls the mixing of non-LFE content. A more logical pairing might be to have the LPF for LFE setting paired with the Subwoofer Yes/No setting under the Speaker Configuration since the LPF setting only gets used when the sub is enabled.

Here are some essentials that you need to know about subwoofer crossover settings: LFE or Low-Frequency Effect is the part of your sound system that produces deep sounds when listening to music or... LFE + Main is a crossover mode that we find in sound systems where it sends deep sounds lower than ...

A good crossover frequency is a range at which the crossover is able to filter the unwanted sounds perfectly. It’s hard to settle on a unified crossover frequency for every speaker because a lot of factors come into play when setting one. However, there are common frequency ranges that will work well in many cases.
