Sound Check: Can You Use 2 Bookshelf Speakers as a Center Channel?

When setting up a home theater system, many enthusiasts wonder if they can use two bookshelf speakers as a center channel. It’s a great question, and one that requires some understanding of how a center channel works and the role it plays in your audio setup.

What is a Center Channel Speaker?

Before we dive into the question at hand, let’s take a step back and discuss what a center channel speaker is and why it’s an essential component of a home theater system. In a surround sound setup, the center channel speaker is responsible for producing dialogue and on-screen action sounds. It’s the speaker that sits directly below or above your TV, and its primary function is to provide clear, crisp audio that’s synchronized with the on-screen action.

In an ideal setup, the center channel speaker should be matched to the left and right front speakers in terms of tone, balance, and overall performance. This creates a seamless audio experience, where the sound appears to come from the screen rather than the speakers themselves.

The Role of Bookshelf Speakers in a Home Theater System

Bookshelf speakers, on the other hand, are designed to be compact, versatile, and easy to place in a room. They’re often used as the left and right front speakers in a home theater system, providing a wide soundstage and excellent music reproduction. Bookshelf speakers are typically smaller and more affordable than floor-standing speakers, making them a popular choice for many audio enthusiasts.

Can You Use 2 Bookshelf Speakers as a Center Channel?

Now that we’ve covered the basics, let’s get back to the question at hand: can you use two bookshelf speakers as a center channel? The short answer is yes, but with some caveats.

In theory, using two bookshelf speakers as a center channel can work, but it’s essential to consider the following factors:

• Stereo vs. Mono: A center channel speaker is designed to produce a single, mono audio signal, whereas bookshelf speakers are typically configured for stereo operation. Using two bookshelf speakers as a center channel would require you to configure them to produce a mono signal, which might not be possible with all speaker models.

• Phasing Issues: When you use two speakers to produce a single audio signal, phasing issues can occur. This is because the sound waves from each speaker can interact with each other, causing cancellations and reinforcements that can affect the overall sound quality.

• Imaging and Soundstage: A center channel speaker is designed to produce a focused, pinpoint sound that appears to come from the screen. Using two bookshelf speakers as a center channel can create a wider soundstage, but it might also compromise the imaging and sound localization, making it harder to pinpoint the source of the sound.

Configuring Bookshelf Speakers as a Center Channel

If you still want to use two bookshelf speakers as a center channel, here are some configuration options to consider:

• Mono Summing: Many receivers and processors offer a mono summing feature, which allows you to combine the left and right audio channels into a single mono signal. This can help alleviate phasing issues and provide a more coherent sound.

• Configuring the Speakers: You can try configuring the bookshelf speakers to produce a mono signal by setting them to “mono” or “center” mode, if available. This might involve adjusting the speaker’s internal settings or using a specialized cable to connect the speakers to the receiver.

• Using a Dolby Atmos or DTS:X Configured Receiver: If you have a receiver that supports Dolby Atmos or DTS:X, you can use two bookshelf speakers as part of a height channel or a wide channel configuration. This can help create a more immersive audio experience, but it’s not a traditional center channel setup.

Pros and Cons of Using 2 Bookshelf Speakers as a Center Channel

Here are some pros and cons to consider when using two bookshelf speakers as a center channel:

Conclusion

While it is technically possible to use two bookshelf speakers as a center channel, it’s essential to consider the potential drawbacks and limitations. A dedicated center channel speaker is designed to provide clear, precise audio that’s optimized for dialogue and on-screen action. Using two bookshelf speakers as a center channel can compromise this performance, leading to a less-than-ideal audio experience.

If you’re looking for a cost-effective solution or a temporary workaround, using two bookshelf speakers as a center channel might be acceptable. However, if you’re serious about creating an immersive home theater experience, we recommend investing in a dedicated center channel speaker that’s specifically designed for this purpose.

Remember, in the world of home audio, there are no shortcuts to greatness. Investing in the right equipment and configuring it correctly will always provide a better listening experience than trying to make do with compromises.

Can I use 2 bookshelf speakers as a center channel in a home theater system?

Using 2 bookshelf speakers as a center channel can work, but it’s not the most ideal setup. The center channel is responsible for producing clear dialogue and vocals, and using two speakers can cause phase issues and affect the overall sound quality. However, if you don’t have a dedicated center channel speaker, using two bookshelf speakers can be a viable alternative.

That being said, it’s essential to configure the speakers correctly to minimize any potential issues. You’ll need to set the speakers to “mono” mode to ensure they’re producing the same audio signal, and adjust the EQ settings to compensate for any phase differences. Additionally, placing the speakers close together and angled inward can help to create a more cohesive soundstage.

Will using 2 bookshelf speakers as a center channel affect my surround sound experience?

Yes, using two bookshelf speakers as a center channel can affect your surround sound experience. The center channel is a critical component of a surround sound system, and using two speakers can disrupt the soundstage and cause dialogue to sound unclear or dispersed. This can be particularly noticeable in movie scenes with lots of conversation or voiceovers.

To minimize the impact, you’ll need to carefully calibrate your surround sound system and adjust the speaker settings to optimize the audio output. You may also need to adjust the seating position and speaker placement to ensure the best possible listening experience. However, even with careful calibration, using two bookshelf speakers as a center channel may not provide the same level of immersion and engagement as a dedicated center channel speaker.

Can I use any bookshelf speakers as a center channel, or are there specific models recommended?

Not all bookshelf speakers are suitable for use as a center channel. Look for speakers with a clear and balanced sound, particularly in the midrange frequency range where dialogue resides. Speakers with a dedicated midrange driver or a tweeter that’s designed for clear, detailed highs can work well as a center channel.

In terms of specific models, some popular bookshelf speakers that could work as a center channel include the Q Acoustics 3020i, the ELAC Debut 2.0 B6.2, or the Dali Opticon 1. However, it’s essential to audition the speakers and listen to their sound quality before making a final decision.

How do I connect 2 bookshelf speakers to my receiver or amplifier?

Connecting two bookshelf speakers to your receiver or amplifier is relatively straightforward. You’ll need to use an RCA Y-adapter cable to split the center channel audio signal into two separate channels, which are then sent to each speaker. Make sure to set the receiver or amplifier to “mono” mode to ensure the speakers receive the same audio signal.

It’s also essential to ensure that the speakers are matched in terms of impedance and power handling to avoid any potential damage to the amplifier or speakers. Consult the user manual or manufacturer’s instructions for specific guidance on connecting and configuring the speakers.

Will using 2 bookshelf speakers as a center channel cause any phase issues?

Yes, using two bookshelf speakers as a center channel can cause phase issues, particularly if the speakers are not identical or are not positioned correctly. Phase issues can result in a cancellation of certain frequencies, leading to a thin, hollow sound or a lack of clarity in the dialogue.

To minimize phase issues, it’s essential to position the speakers as close together as possible, ideally within a few inches of each other, and angle them inward to create a cohesive soundstage. You can also experiment with reversing the phase of one speaker to see if it improves the sound quality.

Can I use 2 bookshelf speakers as a center channel in a stereo setup?

In a stereo setup, using two bookshelf speakers as a center channel is not necessary, as the stereo speakers are designed to produce a wide, immersive soundstage. In a stereo setup, the center channel is not used, and the audio signal is split between the two main speakers.

However, if you’re using a stereo setup to watch movies or TV shows, you may want to consider using a dedicated center channel speaker to enhance the dialogue clarity and overall sound quality. Alternatively, you can use a soundbar with a dedicated center channel speaker to improve the audio experience.

Are there any benefits to using 2 bookshelf speakers as a center channel?

One potential benefit of using two bookshelf speakers as a center channel is that it can provide a wider, more immersive soundstage than a single center channel speaker. This can be particularly beneficial in larger rooms or in situations where a more expansive soundfield is desired.

Additionally, using two bookshelf speakers can provide a more flexible setup, allowing you to move the speakers around to create a more optimized listening experience. However, it’s essential to weigh these benefits against the potential drawbacks, such as phase issues and a potential loss of clarity in the dialogue.
