If you’re utilizing a powered subwoofer in your speaker system, you’ll want to make sure the bass settings are right. LFE+MAIN or LFE is one of the most essential settings. Subwoofer bass settings, often known as subwoofer modes, are LFE+MAIN or LFE.
By selecting the proper bass settings/subwoofer mode, you can guarantee that your amplifier or receiver, as well as your speakers, will operate well with your subwoofer. This article will explain what LFE+Main is and when it should be used.
Why is LFE+MAIN set?
Setting LFE+Main is critical since it determines whether you will get the required sound quality by properly selecting these parameters.
Using LFE+MAIN and setting your speakers to LARGE or SMALL
You must first determine if your speakers are set to SMALL or LARGE before setting LFE+MAIN.
The SMALL and LARGE settings may be found in the speaker setup menu. The following is how various options impact LFE+MAIN:
When the speaker channel is set to small, for example.
The bass setting or subwoofer mode menu may be changed to LFE or LFE+Main when the speaker channel is set to SMALL. All frequencies below the crossover point will be sent to the Subwoofer as a result of this.
2. When the Speaker Channel is Large
The bass setting or subwoofer mode menu may be adjusted to LFE or LFE+Main when the speaker channel is set to LARGE. The low frequencies will be duplicated to the Subwoofer as a result of this.
If you change the bass setting or subwoofer mode to LFE, only the LFE from a Dolby or DTS encoded music will be sent to the subwoofer.

Now that we’ve gone through the settings to use and what impact they’ll have on your subwoofer, let’s look at what these parameters are.
Because most surround sound speaker systems contain a sub, they will include the LFE option. Consider the well-known 5.1 channel speaker setup.
Five full-range primary channels make up the 5.1-surround mix. Center, Right, Left, Right Surround, and Left Surround are the options. A subwoofer is also included, which is powered by a band-limited LFE channel.
Low Frequency Effect is an acronym for Low Frequency Effect. It’s accessible on all DTS and Dolby encoded audio tracks in the surround mix, as well as a separate “.1” channel. Because it is multichannel, it is mostly used for movies and other similar content.
Subwoofers may also handle stereo (2.0 or left and right audio). The frequency is usually shut off around 80 Hz. Check out our post on how to adjust the low pass filter on your subwoofer for additional information.
It’s an effects channel that’s utilized in the optical track since the optical channels don’t have adequate dynamic range for Low Frequency Effects.
As a result, 5.1 systems include 5 channels plus a sub channel plus the LFE channel, as previously stated.
The channel is well-known for its uncanny ability to enhance music and sci-fi settings. LFE also includes around 10% of the low frequencies heard in movies.
LFE+MAIN refers to sound systems with the bass-subwoofer mode menu option on the receiver, which may duplicate low-frequency sounds and transmit them to the main speaker and subwoofer. This makes properly integrating the sub very simple. Whether the speaker channels are set to Large or Small, the low frequencies are sent to the subwoofer in this scenario.
Understanding the Sound Effects in the Environment You’ve Picked
If you go to the receiver’s subwoofer mode menu and choose LFE, the low frequencies from the.1 and speaker channels will be adjusted to “Small” in the configuration menu to output from the sub.
If you choose LFE+MAIN, however, the low frequencies from your speaker channels will start to output to your sub. Whether you set your speaker channels to “Small” or “Large,” you’ll get low frequencies to the sub.
The sound quality is directly influenced by whether you use LFE+MAIN or LFE. Low-pitched sound effects in the 20Hz range are the most difficult to recreate from the viewpoint of a sound engineer.
For example, one could try for hours to duplicate noises used to mimic a rocket launch, earthquake, explosion, or undersea change without success. The truth is that the ears are built to be very sensitive to high-frequency sounds. This implies that the human ear requires a considerable level of amplification to hear them. Low-frequency noises, on the other hand, are typically felt much more quickly by our body.
It’s tough for amplifiers, cabinets, and subwoofers to create sound at high volumes. If you attempt it, you’re likely to run into issues like undesired rattles in wooden speakers, power amplifier distortion, and excessive “chuffing” noises for your bass-reflex speakers’ port.
This is where LFE+MAIN come into play. LFE enables the low frequencies of speaker channels set to “Small” to be produced from the subs, as we’ve seen. Whether your speakers are set to “Large” or “Small,” LFE+MAIN enhances the low frequencies and delivers them to the main speaker.
When configuring LFE+MAIN, keep speaker size in mind.
For appropriate bass control, it’s also important to know the speaker size. We’ve been discussing “Large,” which refers to full-range speakers capable of playing down to 20Hz.
On the other hand, regardless of whether they are more than 6 feet tall, the tiny speakers, dubbed “Small,” lack the ability to play down to 20Hz.
The frequency extension is referred to by the speaker size option in this case.
You’re enabling your sub to do its job whenever you set your speakers to “Small.” The speaker is freed of the strain of producing the lowest frequencies. This breathes fresh life into the speakers and enables them to precisely reproduce the desired frequencies.
When it comes to low-end bass, your subwoofer is eager to take center stage. As a result, this is a better method to preserve your subwoofer than playing back the sensitive LFE channel. Keep in mind that this channel is hardcoded into 5.1 or 7.1 surround sound soundtracks.
The bass management settings are what increase your subwoofer’s responsibilities and feed them sounds that would otherwise be missed in the primary speakers.
When the speakers are set to “Large,” all of the bass, including the 20Hz impulses, is sent to them. There are no signals sent to the subwoofer. Given that many speakers aren’t really “Large,” this is very hazardous. The colossal dimensions are often deceiving.
After taking into account the size of the speakers, it’s clear that LFE+MAIN is still the best choice in many situations.
Whether you use tiny or big speakers, the quality improves. However, you may set them to “Large” and double the low frequencies before sending them to the sub.
When Should You Use LFE+MAIN?
When playing back PCM (2 channel) audio, LFE-MAIN is always the best option.
Using LFE alone may not provide the greatest results at this time. LFE, as contrast to MAIN, delivers solely bass sound (120 Hz.).
Furthermore, it has no direct effect on the soundtrack’s directionality. To put it another way, the goal of LFE is to add to the total bass content.
For the optimum experience, film formats featuring a distinct LFE channel are always mixed with the bass from the MAIN in the appropriate acoustic mixing ratio. LFE+MAIN ensures that you get the appropriate low frequency while playing PCM-based music.
Taking Care of the Subwoofer
Once you’ve chosen to utilize LFE+MAIN, make sure you have an AV receiver that has the bass management settings you’ll need.
Then, set the low-pass crossover on the sub to the maximum level. This prevents the subwoofer’s crossover from interfering with the receiver’s.
You may dial it back and tamper it off a little if you see a peak that you can’t handle easily at the crossover point. The goal is to ensure that the subwoofer is available for playing at all times.
The phase adjustments on the subwoofer may also be used. Switches are used on certain subs, whereas a spinning dial is used on others. If you’re having trouble obtaining a smooth response from your subwoofer and can’t move it, try experimenting with the switch.
Now is the time to start practicing.
If you understand the various speaker sizes and how they affect the sound, using LFE+MAIN to set up your home theater is easy. Hopefully, the material provided here has helped you understand what LFE+MAIN is and how to utilize it effectively.
You may use the fundamental concepts to begin practicing and experimenting with different methods in order to create a fantastic home theater.
The lfe+main marantz is a technology that allows the audio to be sent through two different paths. One path is for the front left and right speakers, and the other path is for the subwoofer.
