Are you looking to buy the best soundbar for your projector? You’ve got some work to do. Buying the wrong soundbar can ruin the audio experience and would be like flushing your money down the drain.

This article explains a few things you should consider when buying a soundbar. In subsequent sections, you’ll find the seven best soundbars for a projector to purchase in 2023.

Can You Use a Soundbar For a Projector?

Soundbars are often pictured next to a sleek flat television, which is why most people associate them with a TV. But that doesn’t mean you can’t use it for other devices.

Yes, you can use a soundbar for a projector. After all, a soundbar is a loudspeaker that outputs the audio.

But you must be cautious about the type of soundbar you invest in. That’s because there are different types of soundbars, and not all of them will be compatible with the projector.

Soundbars differ by the number of channels, length, power, and cost, but the factor you should look into is connections. The soundbar (and the projector) will have one of the following connection types:

  • HDMI/HDMI Arc – This is the most popular digital connection used in Blu-Ray players and gaming consoles. The sound quality is superior and enables surround sound in the room.
  • SPDIF – Also known as TOSLINK, SPDIF stands for Sony/Philips Digital Interface. It utilizes either TOSLINK connectors or RCA connectors with fiber optics cable. The sound quality is among the best, but you’ll have to miss out on high-res audio like DTS HD master audio.
  • Optical – Optical is another digital connection that offers excellent audio quality but is limited to transmitting 5.1 channel audio.
  • Stereo – Unlike the above three connection types, stereo is an analog connection. It’s limited to stereo sound and doesn’t offer high-res audio.
  • RCA – RCA is another analog connection mainly found in older televisions and projectors. The audio quality is decent, but you’d need better cables.

Although it’s possible to convert between the connection types with a converter, it’s better if there’s consistency between the two. So buy a soundbar with HDMI Arc if your projector has its output.

Can You Use a Bluetooth Soundbar on a Projector?

With the advancement in wireless technologies, you now have soundbars with in-built Bluetooth. So, yes, you can use a Bluetooth soundbar on a projector, but only if the projector has Bluetooth capabilities.

When buying a wireless soundbar, check the Bluetooth version on both devices. The latest Bluetooth version is 5.3 at the time of my review. Many soundbars and projectors aren’t there yet.

Wireless soundbars are the norm, and you will find Bluetooth and Wi-Fi in most of them. There can be a mismatch between the Bluetooth versions, i.e., you can pair a Bluetooth 5.2 soundbar with Bluetooth 3.0 projector.

With that said, here are the seven best soundbars currently available for your projector screen:

Polk Audio doesn’t have the aura or the brand power of Sony or Bose, but its sound systems offer the ideal balance of quality and cost. The Signa S3 soundbar is a product that extends that legacy.

It’s an ultra-slim sound bar just over 2″ in height but has an extended length of 41″. Within that space, it has squeezed in two mid-range drivers, two tweeters, and an elevation speaker at the center.

Along with that, the S3 ships with an external wireless subwoofer. These produce the low frequencies like the whoop-whoop noise of a helicopter blade, while the tweeters take care of the high-frequency sounds like chimes.

Furthermore, the soundbar has the patented voice adjust technology that helps you listen to a crisp, clear speech in a movie or conference. Add the Dolby Atmos 3D Surround sound feature, and now you realize why it’s rated so highly.

The Polk Audio Signa S3 is designed to work with all types of TVs, whether 8K, 4K, or HD. Thus, you’ll find many connectivity options, including HDMI Arc, optical, and audio jack, besides the wireless options like Bluetooth and Wi-Fi. Built-in Google Chromecast is another handy feature you may like. 

At under $400, it’s arguably the most competitive soundbar for the projector.

The TV mode is optimized to isolate ambient sounds from speech, thus suppressing background noise. This helps immensely when verbal content is your primary focus.

The Alto 6+ is powered by Bluetooth and can pair up with your mobile or iPad. But you also have optical cable and HDMI cable as connection options.

Last but not least, the soundbar is Roku TV Ready and compatible with the TCL Roku TV remote.

You can add the Sonos Sub subwoofer (not included in the pack) to get that beefy bass.

Where to Place Soundbar with Projector?

Ideally, it would help if you placed the soundbar directly under the projector screen. That’s where they’re supposed to be when used for TV. If you’ve got rear speakers, satellite speakers, or external subwoofers, they are placed as per the seating arrangement.
