How To Connect Two Wireless Subwoofers To One Soundbar
  • Anthony

If you want to boost the bass in your home theater setup, you might be wondering how to connect two wireless subwoofers to one soundbar. While most soundbars come with a built-in subwoofer, adding an extra subwoofer can really help to fill out the low end. Here are a few different ways that can I connect 2 wireless subwoofers to one soundbar?

Do Soundbars Come With a Built-In Subwoofer?

Many soundbars have a built-in subwoofer or a separate partner subwoofer. But some people might think that the bass from these partner subs isn’t good enough and that their sound could distort or get muddy.

A common complaint about soundbars that have built-in subs is their heavy front sound.

This is not to suggest that all soundbars are poor in sound quality. It is just that people familiar with the capabilities of a subwoofer will be able to distinguish between them. Subwoofers that are capable of producing power output and smooth-hitting deep bass notes are the best.

Why Add a Subwoofer to the Soundbar?

Why Add a Subwoofer to the Soundbar

Subwoofers enhance surround sound and the low-pitched audio tone created by your loudspeaker.

A subwoofer is the best option if you prefer a deeper, more power and punch to your movie, music, or battle royale game.

A standalone subwoofer, in other words, would make a movie’s stormy scene sound more authentic. It would be as if thunder was roaring outside your home theater.

Scenes of motorbikes revving up would seem so real that you’d be transported to the highway. The sound of guns during gunfights would make it impossible to hide behind the couch.

If you have a big room or a room with an odd shape, you might want to improve your system and add more subwoofers to get a richer, more powerful sound.

Connecting 2 Subwoofers to a Soundbar: Is It Possible?

You won’t usually be able to add a separate subwoofer to a soundbar. A separate subwoofer can only be connected to a soundbar if they are both packaged together and designed to be paired.

If both the soundbar and subwoofer come from the same manufacturer, it is possible to connect an additional subwoofer. If they are from the same brand, soundbars and subwoofers may be compatible.

Sometimes, the people who make soundbars let you add something extra called a subwoofer to make the sound even better. But they say you should only use the ones they suggest.

How to Connect 2 Subwoofers to a Soundbar

If you put together an entertainment system in a large or oddly shaped room, you can expect to need more than one speaker or subwoofer.

This is the most effective technique to provide a completely immersive audio experience. As a result, be proactive and get a soundbar with twin subwoofers or extensible.

The Nakamichi Shockwave Ultra soundbar comes with two extra speakers called subwoofers that you don’t have to plug in with wires. There are also four more speakers that go behind you to make sound all around you. You can get this soundbar with two subwoofers included.

You can add a second subwoofer to soundbars like the Bose Soundbar 700. But it might be hard or even impossible to connect two subwoofers wirelessly to the soundbar. You might be able to connect one sub wirelessly and the other through a plug-in link.

To connect the two subwoofers to the soundbar via cable, the video below suggests using a 3.5-millimeter Y-split adapter:

1. Connect Non-Matching Subwoofers

If you want to add another subwoofer to your sound system, it’s better to use one made by the same company. If you use one made by a different company, it might not sound good and could make weird noises.

Even if you make sure that the subwoofers that don’t match have the same voltage and other specs, you can’t be sure that the audio quality will be the same.

The amp power and speaker size of your subwoofers are two factors that might negatively impact their coupling.

Also, putting two subwoofers from different brands together may not only lower the audio quality but also hurt the subwoofers. Worse, it may wind up causing damage to other components of your sound system.

So, be sure you correctly match and couple your two subwoofers.

If you have two subwoofers that are exactly the same kind, it can make the sound even better! They will work together perfectly because they have the same parts, power, and can make the same kinds of sounds. Furthermore, comparable brands imply that they are designed to complement one another.

2. Connect Matching Subwoofers to a Different Soundbar

Connect Matching Subwoofers to a Different Soundbar

While subwoofers should not be mixed and matched, a soundbar is an exception. You may connect a pair of same-brand subwoofers to a different brand’s sound system or soundbar.

It will be difficult, but not impossible, and the work must be completed with extreme attention to safeguarding the equipment.

It is critical to examine the specifications of both your soundbar and subwoofers to guarantee that they will work well together.

Check the characteristics of each subwoofer before pairing it with a different brand of sound system or soundbar. It would help if you examined their amps, sensitivities, and impedance.

You should also ensure that the soundbar has a preamp output. An RCA Y-adapter may be used to provide two parallel low-frequency signals to separate subwoofers.

If your soundbar connects to the subwoofer wirelessly, there are now wireless subwoofer adapters on the market that you may test out. These adapters can send audio signals to up to four wirelessly connected subwoofers.

Connecting Three or Four Subwoofers

You can use up to four subwoofers. Make sure they have either RCA line-out or LFE connections. Then daisy chains them using a series of subwoofer cables.

If this is not possible, you might need a home theatre receiver with two subwoofer outputs. These will need to be split so you can feed four subwoofers. That’s a lot of cables, as you can see.

Built-In Dual-Sub Support vs. Adding Dual-Sub Support

Built-In Dual-Sub Support vs. Adding Dual-Sub Support

We believe that adding two subwoofers to your home theater is a fantastic idea. However, certain brand variances make them incompatible. Some brands, for example, will natively handle two subs, while others will accept two subs but may have complications. This is when research comes in handy.

The best thing to do is check your user’s manual or choose a soundbar you know will work. It’s also a good idea to learn how soundbars work in the first place. Our guide about soundbar operation can assist you in making a better-educated selection. Something else to keep in mind is that there is a big difference between native compatibility and just joining two subs.

  • Built-in Dual Sub Support — If you want to enjoy your system’s full capability, this is your best choice. This will enable dual-channel support and improved balancing.
  • Adding Dual Subs – While this is possible, you may only get your sound in mono. However, since they are subs, it may not be a big concern for you.

Your best option is to get a soundbar that can accommodate twin subwoofers. There are a few well-known manufacturers that provide solutions like this. For example, the Sonos Arc (Amazon) natively supports two subwoofers. However, this will need the use of a suitable Sonos Sub (on Amazon). This may be a problem depending on your budget.

If you want to look at other options, the Nakamichi Shockwave Ultra is a great speaker that supports two subs out of the box and is available on Amazon. There are, however, possibilities if you already have a soundbar and wish to connect numerous subwoofers. Remember that adding dual sub support might be difficult.

Your success will be determined by your soundbar and the sort of subwoofers you use. If possible, stick to the same brand to prevent dynamic range and image difficulties.

Speaker Impedance

Assume you have several spare subs lying around and want to utilize them. First, check sure your soundbar can support them. Then you connect everything, but there’s some distorted low-end. Furthermore, it seems that one sub is louder than the other. You should be concerned with your speaker’s impedance, among other things.

This is a very complicated notion, but it simply refers to the amount of power your sub draws. Speaker impedance is typically rated between 4 and 8 ohms. When two subs have differing impedance ratings, you may notice distortion, poor audio quality, and clipping.

You should avoid these things if you want to have clearer audio. You don’t have to link the two subs because you have them.

FAQs About Wireless Subwoofer Connectivity

You should be able to find the answers to your questions. These questions may be in your head.

Can You Connect Two Subwoofers Directly To One Soundbar At The Same Time?

The simple answer to this question is No. Two Bluetooth connections are impossible at once with Bluetooth. You can connect one subwoofer to the other, even if they are different soundbar models.

Is There Any Other Authentic Way To Connect Both Wireless Subwoofers?

No one method will work for everyone. The only way to connect the soundbar to the Bluetooth subwoofers is by using the above method.

Where To Place The Subwoofer With The Soundbar?

Some people prefer to place the old wireless subwoofer behind their heads, but it is best to have them in the center of the room, similar to your soundbar.

It would help if you made sure that there is nothing in the way of the sub’s bass. You can place the sub either to the left or right of your TV or soundbar.

Do Multiple Subwoofers Increase The Bass?

Installing many subwoofers is a great way to get a deeper, more powerful bass. Here’s the deal! You can get a larger one instead of connecting multiple small subwoofers to achieve the desired sound quality for a great experience.

Is It Possible To Connect Any Wireless Subwoofers To A Soundbar

A soundbar doesn’t allow you to add a subwoofer on its own. Usually, this is only possible if the speaker and subwoofer are sold together and are made to work together out of the box.

Is it possible to use a coaxial cable as a subwoofer?

Yes. The Coax digital cable can be used to set up a wireless subwoofer. These cables may not be interchangeable. All video cables, including digital coax cables, have a 75-ohm standard impedance.

Is The Length Of Subwoofer Cables Significant?

Speakers and subwoofers don’t care about the length of the cables. Short version: Electrical signals travel too quickly through cables to make an audible change. However, the distance between the speakers and wireless subs might matter if they are too far apart.

Can Regular Speaker Wire Be Used As A Subwoofer?

It should work. The problem is that speaker wires are often not shielded as they carry an amplified signal. You can go to a radio shop and purchase a soldered or solderless RCA y adapter.
