Can You Add A Subwoofer To Bookshelf Speakers? (If yes then how)

So you have a nice set of bookshelf speakers and thinking about adding a subwoofer. There could be different reasons such as you have an existing subwoofer and want to test it with your bookshelf speaker. Or want to improve or add more bass to your listening experience.

Whatever the reason, the question is can you add a subwoofer to bookshelf speakers?

Yes, you can add a subwoofer to bookshelf speakers and enhance the sound quality. While it’s not an essential addition, a subwoofer can provide richer bass tones and fuller sound reproduction for a more immersive audio experience.

But to add a subwoofer, there are a few things that should be considered. Because if you are not doing it in the correct way then instead of improving, it could ruin the sound quality coming from your bookshelf speakers.

Below you can find out an easy way to connect bookshelf speakers and subwoofers as well as the pros and cons. And I’ll also recommend some of the best subwoofers available on the market today.

Pros of adding a subwoofer to a bookshelf speaker 

There are plenty of benefits of adding a subwoofer to your bookshelf speakers. Mostly because adding subwoofers will add an extra layer to your sound system and the sound will sound a lot more smooth. 

On top of this, adding a subwoofer to your bookshelf speakers will naturally expand the bass response of your speakers. Although bookshelf speakers are good enough they cannot produce low-frequency sound as well as a separate subwoofer. Similarly, the addition of Subwoofers will add greater clarity to your sound and help reduce distortion in sound

Lastly, the addition of subwoofers will take a massive load off of your bookshelf speakers so that they can focus on producing the sound that they are better at rather than focusing on low-frequency sounds. 

Cons of adding a subwoofer to bookshelf speakers

Although the pros of adding subwoofers to your sound system overweigh the cons. However, it is best that you know both sides of the story. Here are some cons of adding a subwoofer to bookshelf speakers. 

Adding a subwoofer will cost you more than sticking to your current setup. Therefore, you will have to spend some extra money on the addition of a subwoofer (and more if you add two subwoofers).

Adding a subwoofer to your bookshelf speakers will also require time and effort – if you can spare the time and effort – and you have the money too, then go for it.

How to add a subwoofer to bookshelf speakers 

Adding a subwoofer to your sound system is a complicated business, if you do know how to do it right, it will overpower everything else. Therefore, you need a proper way to connect your bookshelf speakers to a subwoofer.

Here is an easy way that you can connect your subwoofers to push on speakers.

Secure the connection 

The first step will be to connect your subwoofer using a cable. There are different types of cables, you will have to figure out what works for you. For example, an audio interconnect cable or an extra set of speaker cables. Just connect the cables in the right spot and you will be good to go.

Adjust controls 

Once the cables are connected, you will have to adjust the controls. If you are using a normal subwoofer, then you will have to take care of just two knobs. The volume and crossover frequency. The best way to adjust this is to play a song that you have played on your headphones before (so you know how it is supposed to sound) and adjust the knobs with the sound of the song. 

Adjust the placement of the subwoofer 

Apart from the wire connection and adjustment of controls, the way you place your subwoofers will also have an effect on how they sound. Therefore, make sure that they are on the same level as your bookshelf speakers for the perfect sound. Similarly, adding two subwoofers instead of one will make your speakers sound more even. 

Blast the songs

The last step is to check if the sound is even – you can figure it out by playing your favorite song on the speakers. The sound of speakers is subjective, so you should check if it works well for you – there are no set ground rules for this step.
