6 Different Connection types for subwoofers to TV

#1 Using a Direct Connection

If you want to connect your Subwoofer to a TV, a direct connection is probably the most convenient method.

You can use this method to do almost everything that other processes do.

It doesn’t matter if you are using an older model television or if you are using a newer, high-definition television; a direct connection will work with no other devices or wiring needed.

At first, connect the included stereo cable to your TV’s audio output jack.

Typically, you can find it on the side or back of your Television.

Then, connect the HDMI cable from your cable box or DVD player to the TV’s HDMI port that is located at the audio input port.

Find the input port on your subwoofers, and plug the other end of your HDMI cable into the input port. When you plug your TV into your AV receiver, their connection is automatic.

You don’t have to make any changes to your TV or your AV receiver. It’s the easiest and usually the most popular way to do it.

Double-check that the HDMI cable is long enough to connect the TV by placing the Subwoofer. You should also cover the wires to keep the wiring tidy.

#2 Using a converter

If your TV or Subwoofer has a different kind of port type than your audio system, it’s a good idea to buy a converter device.

They don’t have an identical connection port you can plug into, so having one device with all of your HDMI, Component, and Composite inputs is handy.

Converters are used to convert the signal from your audio source, usually a portable MP3 player, to a format that the Television and Subwoofer can read.

This allows the sound from your audio source to be sent to the TV and Subwoofer.

If you want to connect your Subwoofer to your TV, you’ll need to connect the digital coax output directly from your AVR directly to the Television.

Then connect the other end of the digital coax input cable to the converter to complete this project.

A digital coax cable is included with your AVR and will have a gold or white connector on each end. Simply put the converter between your AVR and the TV.

Connect the HDMI cable through the converter. Ensure all wired connections are plugged in securely and that none of the plugs is loose.

If there is any loose connection, the connection will not be made successfully. Finally, connect the other side of the HDMI cable to the Subwoofer.

However, it’s worth the extra effort if you want to get the most accurate results possible. If you don’t have matching connecting ports, it’s the best way to connect your Subwoofer output to your television.

A receiver can help you to connect the Subwoofer to your TV.

This will give you a more powerful bass effect and a much larger sound stage. Be sure to allow lots of time to complete this method.
