Why Subwoofer Has Two Inputs? [8 REASONS]

A subwoofer is a small and powerful speaker that is used to add bass to your home theater system. Because of its size and power, it is important to ensure that you have enough input ports on your subwoofer so that you can use it with different types of audio sources.

One way to do this is to have two inputs on your subwoofer. This way, you can use it with both stereo music files and movie soundtracks. It also allows you to use the same subwoofer with multiple home theater systems.

If one of your home theater systems has a different type of audio output than the other, simply plug in the second input on your subwoofer and you’re good to go.

So you have a home theater system and you want to add a subwoofer? Great! Here are some reasons why it’s a good idea to have more than one input on your subwoofer.

1: Two Inputs Are Better Than One

Subwoofers come with two inputs, so that you can connect them to two separate amplifiers. This is a great feature if you have more than one amplifier and want to use both inputs at the same time. It can also be helpful if you have a stereo system and want to use the subwoofer as a Solo Speaker.

2. An extra sensitivity adjustment

Subwoofers come in all shapes and sizes, but they all have one common goal- to produce low frequencies. To do this, subwoofers typically use two sets of speaker cones- one for the higher frequencies and another for the lows.

This dual input allows the subwoofer an extra sensitivity adjustment, which can be important if you have a large room with a lot of furniture and walls that block sound from getting out.

Subwoofers come with two inputs for a reason. Some music genres, like hip-hop or electronic dance music, are more bass-heavy than others and require an extra level of sensitivity in order to reproduce the low frequencies accurately.

This is often done by turning up the crossover frequency, which adjusts how much of the low frequencies are sent to the subwoofer’s speaker.

3: It Allows You To Play Different Music At The Same Time

The reason subwoofer inputs have two channels is because stereo audio signals can only carry so much energy. When you play two different music tracks at the same time, the subwoofer can’t handle the power of both signals at once and will overload.

By splitting the signal into two channels, it allows the subwoofer to handle both tracks without issue.

4: It Prevents Feedback Issues

One reason subwoofer manufacturers include two inputs is to prevent feedback issues. In a nutshell, feedback is when one device emits an unwanted sound and feeds that sound back into the audio system, creating an amplified and distorted version of the original audio.

This can ruin a movie or song listening experience, as well as create problems with the audio system’s overall performance. By providing two inputs, the subwoofer can “split” its output between the left and right channels, preventing any unwanted noise from coming back into the main speakers.

5: It Makes It Easier To Set Up And Use Your System

A subwoofer with two inputs makes it easier to set up and use your system. This is especially helpful if you have a stereo system and want to add a subwoofer. You can simply connect the second input to the left or right channel of your stereo.

6: It’s A Lot Cheaper Than Buying Another Subwoofer

Subwoofers come in a variety of shapes, sizes and prices. For example, buying a subwoofer that has two inputs can be cheaper than buying another subwoofer. This is because you can use one input for low-frequency sounds and the other input for high-frequency sounds.

7: It’s A Great Addition For Any Home Theater System

Subwoofers are a great addition to any home theater system. A subwoofer provides low frequency sounds that help to create a more immersive experience for viewers.

Additionally, having two inputs on a subwoofer allows you to use it with two separate systems without having to purchase an additional unit. This makes it easier to build and configure your home theater system.

8: You Can Connect More Sources To Your Subwoofer

One of the great things about purchasing a subwoofer is that you can connect more sources to it to create a more powerful audio experience.

This is especially useful if you have multiple TVs or speakers with built-in subwoofers, or if your current subwoofer doesn’t have enough power to handle all of your audio needs.

For example, say you have two TVs with built-in subs and want to use them both in conjunction with your new subwoofer.

You could simply connect the woofer’s left and right inputs together, or use a splitter cable to connect each TV’s output directly to the woofer’s left and right input ports. This way, each TV can benefit from the full power of the subwoofer.

Why some subs have dual inputs?

Subwoofers are a vital part of any home audio setup, providing the low end response that can make or break the overall sound quality of a system.

Traditionally, most subwoofers have had a single input, but there are now models on the market that feature dual inputs. So why do some subs have dual inputs?

There are a few reasons why a sub might have dual inputs. One possibility is that the sub is designed to be used in conjunction with two different amplifiers, one for each input.

This can be advantageous if you want to use two different amps to drive your subwoofer – for example, one amp might be dedicated to driving low frequencies while another drives higher frequencies – as it can allow you to fine-tune the sound quality of your system more accurately.

Conclusion

Dual inputs are beneficial for several reasons. First, they allow for an extra sensitivity adjustment, which can make it easier to find the perfect sound for your specific listening setup.

Second, dual inputs can be used in conjunction with a crossover to divide the frequency range of your subwoofer into two channels, allowing you to tailor the sound output specifically for either front or rear speakers.

Finally, dual inputs can be used in combination with a powered amplifier to power two subwoofers simultaneously.
