How to Connect a Subwoofer

We all have heart eyes for subwoofers, to be completely honest. The foundation for all of that musical pleasure is the subwoofer, no doubt it is the basis for audio in movies and music.

Although some bookshelf and tower speakers provide tremendous bass. You truly can’t beat the sensation of having a robust 12 or 14-inch speaker cone supporting the low end, in my opinion (other sizes are also available!).

Additionally, if you want to, you can shake the windows! That’s enjoyable. Unless you’re a neighbour.

All those expensive speakers with their posh mid-range and high-range frequencies simply wouldn’t sound as good without a strong low-end.

But you must make sure that your subwoofer is hooked up properly if you want to get the most out of it.

It could appear that installing the speaker is simple. However, there are a few things to consider while wiring your subwoofer.

So what do we need to understand about subwoofer connections?

Types of connections in Subwoofers

A subwoofer can be connected to your speaker system in one of two ways:

Low-level connection also known as LFE and,
High-level connection also known as Speaker-level connection 

The one you choose will typically be determined by the kind of amplifier you are using to drive your speakers. And occasionally depending on the kind of audio you are hearing.

Both connection styles are found on a lot of subwoofers. Some people, though, might only have one or the other.

Some subwoofers have a separate low-level and LFE connection, such as those produced by the well-known subwoofer manufacturer REL Acoustics. However, the majority of brands only feature a low-level or high-level input.

Checking this before you purchase a new subwoofer is a good idea. that it has the appropriate input connections for your system.

However, you won’t typically experience an issue.

Low-level subwoofer connection

A low-level subwoofer connection, also known as a line-level connection, is a type of audio connection that is used to connect a subwoofer to an audio source. It is called a low-level connection because it carries a line-level signal, which is a relatively low-voltage audio signal that is typically used to connect components within a sound system.

There are several types of low-level subwoofer connections, including RCA, 3.5mm, and speaker-level connections. RCA connections are the most common type of low-level subwoofer connection and are typically used to connect a subwoofer to a receiver or amplifier. 3.5mm connections are also commonly used and are often found on portable devices such as smartphones and tablets. Speaker-level connections are another option and are used to connect a subwoofer to a speaker-level output on an amplifier or receiver.

Low-level subwoofer connections are typically used in home theater and audio systems to allow the subwoofer to be connected to the audio source without the need for a separate amplifier. This can be a more convenient and cost-effective solution, as it eliminates the need for additional equipment.

To use a low-level subwoofer connection, you will need to connect the subwoofer to the audio source using the appropriate cable and connection. This will typically involve connecting the subwoofer to the “subwoofer out” or “LFE” (low-frequency effects) output on the audio source using a low-level subwoofer cable. You will then need to adjust the settings on your audio equipment to ensure that the subwoofer is receiving the correct audio signal.

High-level subwoofer connection

A high-level subwoofer connection, also known as a speaker-level connection, is a type of audio connection that is used to connect a subwoofer to an audio source. It is called a high-level connection because it carries a speaker-level signal, which is a relatively high-voltage audio signal that is typically used to drive speakers.

High-level subwoofer connections are typically used in audio systems where the subwoofer does not have its own amplifier and relies on the amplifier in the audio source to power it. This can be a more convenient and cost-effective solution, as it eliminates the need for a separate amplifier for the subwoofer.

To use a high-level subwoofer connection, you will need to connect the subwoofer to the audio source using the appropriate cables and connections. This will typically involve connecting the subwoofer to the speaker-level outputs on the audio source using a high-level subwoofer cable. You will then need to adjust the settings on your audio equipment to ensure that the subwoofer is receiving the correct audio signal.

One of the main benefits of using a high-level subwoofer connection is that it can simplify the overall wiring of an audio system. By using a high-level connection, you can eliminate the need for a separate amplifier for the subwoofer and reduce the number of cables and connections required. Additionally, high-level subwoofer connections can be less susceptible to interference and noise compared to low-level connections, which can help to improve the overall sound quality.

Connecting subwoofer

Now that you are aware of your alternatives, let’s go over connecting a subwoofer in greater depth.

Almost all of these examples employ SVS subwoofers. These speakers are of the highest caliber, and they come in a variety of styles to fit any home theatre space.

Your connections and controls, on the other hand, can be a little bit different if you have a specific brand.

However, in general, most subwoofers will contain comparable settings, so you should have no trouble following along.

Always consult your subwoofer’s handbook if you are unsure, that’s no harm.

How to Connect the Low-Level Input on a Subwoofer

1. Determine the type of low-level connection that your subwoofer and audio source use. Most subwoofers will have a low-level input that is compatible with RCA or 3.5mm connections. You will need to make sure that you have the appropriate cables and connections to match the inputs on your subwoofer and audio source.
2. Locate the low-level input on your subwoofer. This is typically a pair of RCA jacks or a 3.5mm jack, depending on the specific connection type.
3. Locate the low-level output on your audio source. This is typically a pair of RCA jacks or a 3.5mm jack, depending on the specific connection type.
4. Connect one end of the low-level cable to the low-level output on your audio source.
5. Connect the other end of the low-level cable to the low-level input on your subwoofer.
6. Turn on your audio source and subwoofer and adjust the settings as necessary to ensure that the subwoofer is receiving the correct audio

 

What is the purpose of Two Line Level Inputs?

A subwoofer with two line-level inputs, also known as low-level inputs, is designed to allow the user to connect multiple audio sources to the subwoofer. Line-level inputs carry a relatively low-voltage audio signal and are typically used to connect components within a sound system. There are several types of line-level inputs, including RCA, 3.5mm, and speaker-level connections.

Having two line-level inputs on a subwoofer can be useful for a number of reasons. One reason is that it allows the user to connect multiple audio sources to the subwoofer, such as a receiver and a media player. This can be convenient for people who want to be able to switch between different audio sources without having to unplug and reconnect cables.

Another reason why a subwoofer may have two line-level inputs is to allow for more flexibility in terms of placement and setup. For example, if the subwoofer is located in a different room from the audio source, the user can use one of the line-level inputs to connect the subwoofer to the audio source and the other line-level input to connect a second audio source, such as a television. This can be especially useful in larger homes or in situations where the audio source is not easily accessible.

In terms of compatibility, it is important to make sure that the line-level inputs on your subwoofer are compatible with your audio source. You will need to make sure that you have the appropriate cables and connections to match the inputs on your subwoofer.

How to Connect the High-Level Input on a Subwoofer

Connecting the high-level input on a subwoofer is a process that involves using a high-level audio connection to connect the subwoofer to an audio source. High-level connections, also known as speaker-level connections, carry a relatively high-voltage audio signal and are typically used to drive speakers.

To connect the high-level input on a subwoofer, you will need to follow these steps:

1. Determine the type of high-level connection that your subwoofer and audio source use. Most subwoofers will have a high-level input that is compatible with speaker-level connections. You will need to make sure that you have the appropriate cables and connections to match the inputs on your subwoofer and audio source.
2. Locate the high-level input on your subwoofer. This is typically a pair of binding posts or a terminal block, depending on the specific connection type.
3. Locate the high-level output on your audio source. This is typically a pair of binding posts or a terminal block, depending on the specific connection type.
4. Connect one end of the high-level cable to the high-level output on your audio source.
5. Connect the other end of the high-level cable to the high-level input on your subwoofer.
6. Turn on your audio source and subwoofer and adjust the settings as necessary to ensure that the subwoofer is receiving the correct audio signal.

It is important to note that high-level connections are typically not as common as low-level connections, and may not be available on all audio sources.

 Connecting Speaker Wire to subwoofer

Connecting a subwoofer with speaker wire is a process that involves using a pair of wires to connect the subwoofer to an audio source. Speaker wire is a type of wire that is specifically designed to carry audio signals and is typically used to connect speakers to an amplifier or receiver.

To connect a subwoofer with speaker wire, you will need to follow these steps:

1. Determine the type of connection that your subwoofer and audio source use. Most subwoofers will have a pair of binding posts or a terminal block that are compatible with speaker wire. You will need to make sure that you have the appropriate wire and connectors to match the inputs on your subwoofer and audio source.
2. Locate the binding posts or terminal block on your subwoofer. This is where you will connect the speaker wire.
3. Locate the binding posts or terminal block on your audio source. This is where you will connect the other end of the speaker wire.
4. Strip the insulation off of the ends of the speaker wire, exposing the bare wire.
5. Connect one end of the speaker wire to the binding posts or terminal block on your audio source.
6. Connect the other end of the speaker wire to the binding posts or terminal block on your subwoofer.
7. Turn on your audio source and subwoofer and adjust the settings as necessary to ensure that the subwoofer is receiving the correct audio signal.

It is important to note that speaker wire is typically color-coded, with one wire being red and the other being black. It is important to match the correct wire to the correct terminal on both the audio source and the subwoofer to ensure that the audio signal is properly transmitted. Additionally, it is important to use the correct gauge of speaker wire for the distance between the audio source and the subwoofer to ensure that the audio signal is transmitted properly.

Connecting Neutrik Speakon to a subwoofer

Connecting a subwoofer with a Neutrik Speakon connection is a process that involves using a specialized audio connector to connect the subwoofer to an audio source. The Neutrik Speakon connector is a type of audio connector that is specifically designed for professional audio applications and is widely used in concert sound systems, recording studios, and other professional settings.

To connect a subwoofer with a Neutrik Speakon connection, you will need to follow these steps:

1. Determine the type of connection that your subwoofer and audio source use. Most subwoofers will have a Neutrik Speakon connector that is compatible with a Neutrik Speakon cable. You will need to make sure that you have the appropriate cable and connectors to match the inputs on your subwoofer and audio source.
2. Locate the Neutrik Speakon connector on your subwoofer. This is where you will connect the Neutrik Speakon cable.

They are also resistant to interference and are less prone to wear and tear than other types of connectors. As a result, they are often preferred by professional audio engineers and technicians.

Is it Possible to Connect Both the High and Low-Level Connections at the Same Time?

It is generally not recommended to connect both the high and low-level connections on a subwoofer at the same time. This is because doing so can potentially cause problems with the audio signal and may result in poor sound quality or even damage to the audio equipment.

High-level connections, also known as speaker-level connections, carry a relatively high-voltage audio signal and are typically used to drive speakers. Low-level connections, also known as line-level connections, carry a relatively low-voltage audio signal and are typically used to connect components within a sound system. Connecting both types of connections at the same time can result in conflicting audio signals and may cause problems with the overall sound quality.

Additionally, connecting both the high and low-level connections at the same time can potentially cause damage to the audio equipment. This is because the high-level signal is significantly stronger than the low-level signal and may overload the low-level input on the subwoofer, potentially causing damage to the subwoofer or the audio source.

Therefore, it is generally recommended to only use one type of connection at a time when connecting a subwoofer to an audio source. If you are unsure which type of connection to use, it is always a good idea to consult the manual for your audio equipment or seek the advice of a professional.

Connecting a Wireless Subwoofer

Connecting a wireless subwoofer is a process that involves using a wireless connection to link the subwoofer to an audio source. Wireless subwoofers are designed to offer greater flexibility and convenience in terms of placement and setup, as they do not require the use of physical cables to connect to the audio source.

There are several ways to connect a wireless subwoofer, depending on the specific make and model of the subwoofer and the audio source. Here are some general steps that you can follow to connect a wireless subwoofer:

1. Determine the type of wireless connection that your subwoofer and audio source use. Most wireless subwoofers use Bluetooth or Wi-Fi to connect to the audio source. You will need to make sure that both the subwoofer and the audio source are compatible with the same type of wireless connection.
2. Turn on your audio source and subwoofer and put them in “pairing” mode. This is typically done by pressing and holding a button or activating a setting on the device.
3. On your audio source, search for available Bluetooth or Wi-Fi devices and select the subwoofer from the list of available devices.
4. Follow the on-screen instructions to complete the pairing process. This may involve entering a PIN code or completing other authentication steps.
5. Once the subwoofer is paired with the audio source, the subwoofer should automatically connect to the audio source whenever it is turned on and within range.

Connecting two subwoofer to an av receiver

While most rooms can get by with only one subwoofer, adding two or more subwoofers can have certain benefits.

The fundamental advantage of having numerous subwoofers is that they will smooth out the bass response throughout your space, providing a balanced low, mid, and high frequency sound at each listening position.

Low bass frequencies have a challenge since the sound waves’ wavelength is quite long. And this might lead to a variety of issues when attempting to get a balanced sound in a confined space.

Spreading the bass throughout the space and avoiding any peaks or troughs in certain frequencies can be accomplished by adding an additional subwoofer.

So how can you upgrade your system to include a second subwoofer? There are several options.

AV Receiver with Dual Subwoofer Outputs

Two subwoofer outputs are now a common feature of modern AV receivers.

Therefore, if your AV receiver provides this option, that is the simplest approach to add another subwoofer.

One subwoofer must only be connected to the “Sub 1” pre-out. And the other’s “Sub 2” pre-out.

As previously mentioned, a single RCA wire would be used to connect them all.

The majority of AV receivers simply output the identical audio stream from each output.

Some more expensive receivers, nevertheless, feature a separate audio feed from each output. Due to the possibility of differing treatment requirements for subs in various positions, this can make it simpler to EQ and balance the bass in the room.

Using a Y Splitter Cable

Simply connect the one connector to your AV receiver’s subwoofer pre-out. Then connect the two extensions to the respective subwoofer inputs.

 After that, just configure your AV receiver as usual.

The distance and separation between the subs are the essential factors to take into account. It will be simpler if they are close to one another because the cable will need to reach both.

Purchase a shorter Y-adapter, such as this one, if you think it would be an issue:

Then, just attach two longer, independent RCA connections to each sub.

This may make it simpler to run wires to the subwoofers wherever they are located in the room.

Daisy-chain the Subwoofers

Only your subwoofers can support you in doing this. However, some subs have both an input and an output at the line-level.

In this scenario, you would connect the first subwoofer to the AV receiver as usual.

The output of the first sub would then be connected to the input of the second sub using an RCA connection.

Daisy-chaining is the term for this. when a signal is transferred from one device to another.

This enables you to add an additional subwoofer to a single AV receiver output while also streamlining the wiring in your space.

Using this technique, you can increase the number of subwoofers in your home.

Always consult your subwoofer’s handbook to learn about any restrictions on this procedure.

You should only daisy chain connections of the same kind, for instance. This indicates that the stereo line output on subwoofer 1 should only be used if the stereo line-level input on the AV receiver is connected.

Conclusion

That’s all there is to it. You actually believed it was simple to attach a subwoofer to your speaker system!

It can be, which is wonderful news.

But when connecting a subwoofer, there are a number of considerations to take into account.

The most important decision is whether to use high-level or low-level connections. as well as whether both of these options are supported by your hardware.

It’s not too difficult to connect the connections, but it can be challenging to find out how to configure everything.

However, after everything is in order, upgrading your speaker system with a high-quality subwoofer can significantly improve the sound quality in your home.
