How to connect subwoofer to soundbar ultimate guide 2023

In this post, we will discuss how to connect subwoofer to your soundbar. The best soundbar has the ability to connect your TV to home theater subwoofers in your home and deliver a superior sound experience. So, we are going to explain the basic installation steps to get a subwoofer connected to your soundbar.

There are two types of connections

Automated Connection

There should be a power cord connected to the back of each unit for the sound bar and subwoofer. Plug them into an outlet at the end.

It is not necessary to turn on the sound bar for the dedicated subwoofer to begin connecting automatically. Indicator lights on the subwoofer will stop blinking when the subwoofer is fully connected. A continuous glow occurs until the blinking stops. Unless the blue LED stops blinking, the process fails. There is a red light on.

Manual Connection

  • Manually pairing the subwoofer is possible if necessary. The soundbar can be reset after it has been serviced or changed.
  • The subwoofer and the soundbar should be powered from the back of each. In the end, plug them into an electrical outlet.
  • Your subwoofer’s ID SET button is located at the back. Press it with a pointed object.
  • When STANDBY no longer blinks and LINK turns off, continue holding down.
  • Turn off the soundbar and hold Mute.

The ID SET pairing button is not available on all soundbar models. It is necessary to use the remote control to perform ID SET. While pressing the Mute button, hold the Up button if ID SET doesn’t take place. Refer to the manual of your soundbar for instructions on how to use either of these buttons.

  • Once ID SET is displayed on the soundbar, continue holding down.
  • Once the soundbar is turned on, the subwoofer’s Blue LED will blink to confirm the connection.
  • We have now connected the main unit and subwoofer. You should now see a solid green LED in the blue area. When the Blue LED blinks, the process fails. Once the soundbar is turned off, repeat Step 2 again.

Subwoofers For Soundbars: Why Do You Need Them?

Reasons You Should Get One

  1. You will be able to enjoy high-quality audio right from the start of your home theater installation if you have a subwoofer that will last you for decades to come. The most iconic scenes in movies from the last two decades are characterized by high-quality explosions, bullets hitting walls, and character dialogue. The high-quality bass that comes with a subwoofer is also appreciated by movie watchers and gamers.
  2. You might be surprised at how affordable subwoofers are. My family still uses this Sony subwoofer to this day. In comparison to stand-alone brands that cost more, we got this for a great price. This is actually an affordable way to upgrade your current setup. Besides saving some money on the initial purchase, you can also consider soundbars without built-in subwoofer systems.
  3. There is a lot more control over your sound settings with a subwoofer than with a built-in soundbar speaker. It’s easy to overdo the settings so that every time you watch a movie, you end up adjusting them, but if you’re that motivated, you can plug in a subwoofer to do so. It is extremely convenient to be able to adjust your base settings from outside the soundbar in some movies that have a difficult-to-understand dialogue by nature. There are some people who mount their soundbars in hard-to-reach areas, so a subwoofer adds another layer of flexibility.

A Soundbar’s Subwoofer: 5 Things to Consider

1.  There are some soundbars that do not support powered subwoofers or subwoofer amplifiers. In the event that you’re looking for a soundbar that comes with an adapter cable, such as the SVS SoundPath RCA Audio Interconnect Cable, this information will be helpful. It is compatible with most subwoofers, including all SVS models.

2. The cabinet’s size. There is a minimal visual impact of soundbars on a room, which makes them popular. You should choose a compact subwoofer if your lifestyle requires it. A home’s décor can be discreetly integrated or hidden. Subwoofers with sealed cabinets usually have smaller footprints and dimensions than those with ported enclosures.

3. Listening preferences and playback levels. Soundbars do not need to be oversubscribed, according to SVS Sound Expert Ed Mullen. 5.1 surround sound systems or even stereo speakers can’t produce the same output as soundbars. In terms of bass response and impact, a subwoofer will not make a significant difference. You might benefit from a larger, more powerful subwoofer if you like to dance and watch action movies at high volumes.

4. The room’s dimensions. An open-plan living room or basement might not generate enough energy with a small subwoofer. In large areas, you might consider a subwoofer with a larger size.

5. A subwoofer’s accessories. By installing a wireless subwoofer kit, you can reduce visual impact and increase placement options. A soundbar can be positioned opposite a subwoofer on the opposite wall. Interconnect cables for subwoofers are no longer required. Two subwoofers can be connected to a soundbar with RCA Y adapters. This option is possible, even though it is rare.
