Learning how to connect a projector to a speaker only takes a few minutes. You’ll find most information in the product manual for either device. But for a quick summary, check the audio output options, whether you’ll be using a cable or wireless connection. Next, connect the speaker via cable or Wi-Fi, and ensure the projector finds the speaker. Adjust the audio settings to the appropriate audio source and set the volume to a comfortable level. Finally, test the connection to hear audio from the speaker. That’s it!

No matter the connectivity type, there are a few steps that remain the same. The biggest hurdle in finding the best projectors is the research involved. The second biggest hurdle is figuring out audio connections and the setup involved. For a more detailed guide, keep reading.


  • The first step in making the projector-to-speaker connection is figuring out whether you’re dealing with a wireless speaker or a model that requires manual connections
  • There are different audio connection types, so check your model’s tech specs to figure out which speaker cables to use with your projector.
  • Most manufacturers offer a customer service line you can call to help walk you through troubleshooting the difficulties you run into.

Connecting Projectors and Speakers – Step By Step

To connect via streaming devices, follow the directions included. You should always keep these booklets for instruction purposes.

Insider Tip

Having a wireless or Bluetooth connection can help you keep your home theater tidy by removing the mess of wires.

STEP 1 Confirm a Wireless or Wired Connection

You’ll need to make sure the audio connection types match up with manual connections. While some projectors offer multiple connection types, others will rely on one type alone. Some of these audio output connection types include:

  • HDMI Cable
  • Built-in AUX Input (Headphone Jack)
  • Channel RCA Connection
  • Analog Video Connection


Ensure that you clarify what connection type the speaker you purchase has and whether it’s compatible with your projector.

STEP 2 Connect Your Audiovisual Products

Once you figure out the audio connection types, it’s time to hook your speaker to your projector. Power off both devices before making audio output connections. For Bluetooth tech, you’ll follow the directions in your instruction booklets. Most Bluetooth speakers will make a confirmation sound upon successful pairing. Audiovisual connection isn’t all that matters, however. If the question, “What to use for a projector screen?” comes up, there are multiple options out there you’ll love.

STEP 3 Enjoy Additional Devices as Desired

Whether your audio cable is connected or your Bluetooth tech is set up, you’re now ready to enjoy the same sound waves you might find in a cinema. Adding a Blu-Ray player, wireless streaming stick, or video streaming box into the mix can further up the ante. Plus, you can connect your tablet to the projector for even more streaming options. There are tons of choices for creating the perfect home theatre.

Troubleshooting Projector to Speaker Connections

Sometimes you might run into trouble when looking for an audio signal or getting both devices into the “pairing mode” required for a wireless connection. When troubleshooting, it’s essential to look into the instructional manual for both devices. If that fails, reach out to the brand or a connection specialist in your area.

How do I get sound from my projectors to my speakers wirelessly?

Some speakers require you to connect with a coaxial cable or even a headphone jack. Choose a Bluetooth-enabled device for a wireless connection between your projector and speaker.

How do I create a surround sound experience?

Make sure you don’t have poor-quality speakers. The audio device you invest in decides how convincing your audiovisual products will be. Movies are easier to immerse in when you have great sound quality.

Should I buy external speakers for a portable projector?

If your projector has built-in speakers, check their audio quality. Poor-quality speakers can ruin an experience even with the best streaming devices money can buy.

Are complex home entertainment connections worth it?

Investing in internal speakers dramatically improves your experience. Even single soundbars can produce far better audio quality than a built-in speaker system.
