Does a subwoofer work without speakers? (2023)

If you're trying to achieve the low frequencies that a subwoofer can produce without using (or having to use) speakers, you might be wondering how that could possibly work. After all, it looks like they're going hand in hand. This can leave you in a state of confusion.

Does a subwoofer work without speakers? Yes, with the right connection, you can get the low end of a subwoofer without using a speaker system. To do this, use a line-level RCA converter or speaker inputs with an active subwoofer. With an unpowered subwoofer, use a low frequency crossover to connect to the receiver.

Of course, there can be many different reasons why you might want to do this.

Whether you're using older gear or just trying out your new subwoofer, you can use these relatively simple hookups to get you there.

Just be sure to monitor the specific type of receiver and subwoofer you're using and don't try to connect if you're unsure if it's stable. Let's take a closer look.

How to connect a subwoofer without speakers

As you sit at the traffic light anxiously waiting for it to turn green so you can drive to your destination, you hear low-pitched audio frequencies and reverberations from a car playing very loud bass.

You wonder how you can get the benefits of a subwoofer your way, even if you don't use speakers.

So how do you connect a subwoofer without speakers? For a powered subwoofer, use a line level RCA converter to connect the subwoofer to the receiver and choose whether or not to connect the speakers. Another option is to use speaker level inputs. For an unpowered subwoofer, use a low-frequency crossover and avoid connecting speakers.

While this may sound annoying, it really shouldn't take you a lot of time, effort, and energy to figure out how to do it.

(Video) What are the differences between a speaker and a subwoofer?

Connecting a subwooferno speakers means you are pairing your receiver with a stereo system that is responsible for low audio frequencies. Although it is not a speaker, it can help you get higher quality sound effects.

Let's take a look at the top three ways to connect a subwoofer without speakers.

1. Use a line level RCA converter

Does a subwoofer work without speakers? (1)

If you're using a powered subwoofer (one that has a built-in audio input and electronic amplifier), you can connect your sound system to a speakerless receiver in two ways.

The first way is to use a line level RCA converter. To do this, follow these steps:

Check the specifications of your subwoofer

Before you start working on any type of connection to sound devices, it is important to know what you are working with. In this case, you should check the connection options of your subwoofer and those of the receiver.

You should find fairly standard features including audio inputs and outputs, power options, etc. With this connection method, you connect the RCA ends (usually red and white) of the converter to the subwoofer's RCA input jack (usually a male connector on the other end of the Y-cable ).

Make sure your computer meets these specifications if you plan to use this method of connection.

Buy all the necessary equipment.

Now that you know your gear can work this way, you can go ahead and buy any gear you don't have.

Hopefully this will just be a simple purchase of a line level RCA converter. Otherwise you need the subwoofer and the receiver.

Connect the line level RCA converter to the receiver

Now that you have all the necessary equipment (which is a short list, thankfully) you can start making the connection between your RCA line-level converter and your receiver.

Sincespeaker level outputswitch to a lower power, you can rest assured that both teams are safe.

You will likely connect the double ended Y-cable (red and white) to the speaker level inputs on your receiver. This leaves you with the single end of the Y-cable to connect to your subwoofer.

Connect the RCA line level converter to the input socket of the subwoofer

After you connect the RCA line level converter to the receiver, you need to take the single end of the Y-cable and connect it to the subwoofer. This should be fairly easy provided there is a place to make the single RCA input connection.

The RCA line level converter ensures that the audio coming from the speaker input options is at a suitable level for the subwoofer. This allows the equipment to safely receive the low-level signal.

Run a performance test

Now that you've established a connection between the two computers, it's safer to run a performance test before you start playing music or other audio out loud. You can find the best way to perform a performance test for your specific computer.

Start streaming your audio

Now you should be done. It's time to enjoy the newly connected subwoofer.

2. Use speaker level inputs

If you are using an active subwoofer, you can also connect your subwoofer without a speaker via a speaker input.

If you have a subwoofer with speaker level input options (instead of or in conjunction with an RCA in/out option) you can make this connection. You can even do this with other speakers, but it's not necessary (especially if you're trying to go without).

(Video) How to Connect a Subwoofer to Anything V2.0

If you are using speaker-level inputs to connect your subwoofer to a speakerless receiver, follow these steps:

Check your subwoofer

Again, you should verify that your subwoofer has the ability to make this connection before proceeding.

You should also make sure your receiver can connect this way. (But what kind of receiver doesn't have these input options?)

What you are looking for are two speaker input connectors. Instead of the cinch connection option, connect cables directly from the receiver to the subwoofer. These ports will likely be red and white.

Buy all the necessary equipment.

Luckily, you don't have to go out and buy something unique if you choose this option. You use the input cables to connect the speakers as well as the receiver and subwoofer. Since you probably already have them, they should be in good condition. And if not, at least the list is short.

Connect the subwoofer via the speaker level inputs

Now that you've sorted out all the logistics, lay the appropriate audio cable from the speaker's level input to the subwoofer.

Make sure you are pairing the correct cables appropriate for the model of receiver and subwoofer you are using and consult your owner's manual if you have any questions.

adjust your tone

Now that you're connected, it's a good idea to test again and make any necessary adjustments before proceeding with the full flow.


Once you've run a performance test and are ready to hear low frequency audio, it's time to enjoy the connection you just made.

3. Use a low-pass filter

If you're using an unpowered subwoofer (one that doesn't come with an electronic amplifier and built-in RCA jack), you can use a low-pass crossover to connect the subwoofer to the receiver without speakers.

(Video) How Speakers Make Sound

Since an unpowered subwoofer isn't that common, you might not have this problem. However, these subwoofer boxes are more popular than you might think, so knowing what to do with them is important.

In order to connect your subwoofer without a power supply to a receiver without loudspeakers via a low-pass filter, you must proceed as follows:

Check your subwoofer

Again, you need to make sure you know what you're working with. An unpowered subwoofer is the only type of subwoofer that you can use this connection method with. If your subwoofer does not have an internal electronic amplifier, you are probably using an unpowered subwoofer in an enclosure.

Buy all the necessary equipment.

If you're sure your subwoofer isn't getting power, be sure to purchase a low-frequency crossover. They should be well labeled and not too difficult to connect to your receiverSubwooferafter the purchase.

Connect the low-pass filter

If you use one low-pass crossover when you have a single voice coil, or use two low-pass crossovers when you have a double voice coil, you can connect them togetherAudiokabelfrom the receiver to the input options for the subwoofer through the crossover assembly.

The audio signal is correctly transmitted to the subwoofer so that it receives the reproduced low-frequency sound.

However, since this method cannot be used with the established connection of other speakers, you cannot connect them to the same receiver either.

Enjoy an established connection

Now that you've hooked up your receiver and subwoofer, it's time to perform a performance test and enjoy.Stream your media.

Ideally, you should never be able to hear the bass coming from the sub; it should appear to come from the speakers. Try to keep the sub within a few feet of small left front or right front speakers.

Why does subwoofer have speaker outputs? ›

Some stereo amps and preamps have a “subwoofer out” which is usually just a preamp output, meaning it's a regular full-bandwidth line-level signal that relies on the subwoofer's crossover to decide how much high-frequency information the sub will throw away, and how much low-frequency information it will keep.

Can you use a subwoofer alone? ›

These frequencies cannot be generated by traditional speaker systems, so without a subwoofer, you lose out on a significant portion of the artist's intended sound. Of course, a subwoofer is never used alone and needs to be connected to a quality speaker system to utilize its full potential truly.

How do I get only bass from my subwoofer? ›

Play music through your receiver at about one-quarter volume. Turn up the gain of the subwoofer amp until the sound from your subwoofer completely overpowers the other speakers, without distorting. Turn the gain up until it distorts, then back it off until the sound is clean again.

How do you get deep bass? ›

For deep bass, you're going to want to use a low-pass filter to cut out the higher frequencies of the bass notes, and then shape it with the filter and amplitude envelopes. Using the low-pass filter cutoff, we cut the higher frequencies out. Next, played with the filter resonance to add some depth and color.

Which sound mode is best for bass? ›

Bass exists between about 20Hz and 200Hz.

Every musical note corresponds with a frequency. If you want to maximize your bass-heavy music, you need to adjust your equalizer within the 20-200Hz range by boosting the decibels (dB) in that range.

Does a subwoofer need a power source? ›

Passive subwoofers require an additional power source like a receiver or amplifier. Active subwoofers include a built-in amplifier and power source and only need to receive an audio source.

Is a woofer the same as a speaker? ›

What is the difference between Speaker and Woofer? Speaker is the overall sound reproduction system, and woofer is a part of this sound system. Speaker system is made up of parts like tweeter and woofer and even subwoofers. Woofers are designed to reproduce low sound frequencies in the range of 40 Hz to 1 KHz.

Does a subwoofer connect to speakers? ›

So instead of using those connections, we'll use the subwoofer's speaker-level, aka "high-level," inputs. Most, but not all, subwoofers have these inputs; they get connected using speaker cables to the same speaker output jacks on your receiver or amplifier that are also hooked up to your speakers.

Is it better to have a subwoofer in front or behind you? ›

Subwoofer placement in the front of the room is the most common and usually results in the best blending with the main speakers and center channel and minimizes localization effects. Bass is omni-directional.
