5.1 vs. 7.1 Surround Sound: Which Is Better?

Starting your home theater project means deciding between a 5.1 or 7.1 surround sound system. This important choice affects how you’ll enjoy movies and music at home, and it depends on a few key things. But how do you know which one is better for you?

Choosing between 5.1 and 7.1 surround sound depends on room size and personal preference. 5.1 is ideal for smaller spaces, offering balanced audio without overwhelming. 7.1 suits larger rooms, providing immersive, theater-like sound. Consider room acoustics and desired audio depth to decide.

In this guide, we’ll explore the differences between 5.1 and 7.1 systems, looking at what they offer and how they work in different spaces. We’ll consider how the size of your room and your listening habits should influence your decision. Whether you want a full cinema sound or just a better audio setup, this article will help you make the right choice for your home theater.

What’s the Difference Between 5.1 and 7.1 Surround Sound?

Quite simply, the difference between a 5.1 and a 7.1 surround sound system is two speakers. A 5.1 system consists of five speakers and one subwoofer, while a 7.1 system consists of seven speakers and one subwoofer. (Source)

A 5.1 system typically has three front speakers (right, left, and center) and two side surround sound speakers. A 7.1 system enhances sound immersion by adding two rear speakers behind the listening area, optimizing the speaker arrangement for a more enveloping experience.

5.1 Surround Sound Pros and Cons

Surround Sound Channels - 5.1

A 5.1 sound system has several advantages and disadvantages. Despite the diminished size relative to a 7.1 system, a 5.1 audio system could make more sense for your particular home theater.

Basic 5.1 home cinema systems, being more common, offer easier online troubleshooting and often come as ready-to-use packages. With two fewer wires than 7.1 systems, they are simpler to set up and typically provide ample sound for most rooms.

In larger rooms, a 5.1 system might not be adequate, as its surround sound might not feel as immersive, especially with ample space behind the listening area. Additionally, some media optimized for 7.1 sound won’t be fully utilized by a 5.1 system.

For most applications, a 5.1 system will do, However, several disadvantages might make upgrading to a 7.1 system more appealing. We think a 5.1 system is a more obvious solution for people who are working with a limited space or smaller room.

7.1 Surround Sound Pros and Cons

Surround Sound Channels - 7.1

A 7.1 sound system also has its advantages and disadvantages. Despite the added power of two additional surround speakers, a 7.1 system may be detrimental to your listening experience.

A 7.1 system is perfect for larger rooms where sound may get lost in the space. It provides a deeper surround sound listening experience. Theater quality media designed for a 7.1 system will come through clearer than it would on a 5.1 system.

Still, there are several disadvantages to a 7.1 system. In smaller rooms, the additional surround sound speakers may make the surround sound channels dominate over the front channels. This will make the dialogue and front-side sound effects difficult to hear.

In addition, a few 7.1 systems come as a ready kit and will require you to buy components separately. Because of this, it’s difficult to find an online community to help troubleshoot your system since the components will be unique to your setup.

5.1 or 7.1 Soundbar For Gaming?

When it comes to gaming, the audio environment can significantly affect the experience. Choosing between a 5.1 and a 7.1 soundbar depends on your gaming needs and room setup.

  • 5.1 Soundbars: A 5.1 setup offers a surround sound experience with five speakers and a subwoofer. It’s great for a wide range of games, providing clear, directional audio that enhances gameplay in most environments. It’s particularly suitable for smaller rooms and for gamers who enjoy a variety of game genres.
  • 7.1 Soundbars: A 7.1 setup adds two additional speakers, creating a more enveloping sound field. This is particularly beneficial in first-person shooters or games where audio cues are crucial for detecting enemy movements.

5.1 and 7.1 Surround Sound Layout

As previously mentioned, the difference between a 5.1 surround sound system vs 7.1 system is two surround speakers. These additional surround speakers add depth to fill large rooms with theater-quality sound.

A 5.1 system has a fairly standard setup. There is a center speaker that goes below your TV or projector and two front speakers that go on either side of the TV. Last, two surround speakers are placed on either side of the listening area.

On the other hand, a 7.1 system adds two speakers. Otherwise, it is set up the same way. The five speakers the system has in common with a 5.1 system are set up the same way. The additional surround speakers are designed to go behind the listening area at a different angle than the first set of surround speakers.

It’s not uncommon for these speakers to be mounted on (or in) the ceiling. The advantage to ceiling mounting besides the interesting sound experience is that it keeps the area behind the listening area free for walking.

What’s Right for Your Room?

Several factors are going to affect whether a 5.1 or 7.1 sound system is appropriate for your room. Just because you want enormous, theater-quality sound from a 7.1 system doesn’t mean you will get it in just any room. There are three major characteristics of a room that will determine what kind of sound system is right for it.

  • Room Size:
    • Large rooms benefit from additional speakers.
    • In rooms under 350 square feet, 7.1 systems may overwhelm with unclear sound.
  • Listening Position:
    • 7.1 systems place speakers behind the listener for full surround sound.
    • Not ideal if there’s limited space behind the listening area.
  • Furnishings:
    • Hard surfaces (tables, desks, cabinets, wood/tile floors) reflect sound, impacting speaker effectiveness.
    • Soft surfaces (bookshelves, couches, carpeting) absorb sound, enhancing speaker performance.

Features and Your Budget

As expected, a 7.1 system will be more expensive than a 5.1 system. It has more components and is capable of a richer sound experience. That said, different factors will impact how expensive your system will be.

  • Receiver:
    • Essential for converting TV signals to speaker-level signals.
    • 5.1 systems often include a receiver; 7.1 systems usually don’t.
    • Possible to upgrade from 5.1 to 7.1 by adding a receiver and two speakers.
  • Wires:
    • Many systems offer wireless setups for convenience.
    • Wired connections provide superior audio quality.
    • Consider the trade-off between ease of setup and audio fidelity.
  • Calibration:
    • Some systems have internal calibration using test tones and a microphone.
    • Optimizes sound for your room’s acoustics.
    • More common and expensive in 7.1 systems.

Price Differences Between 5.1 and 7.1 Surround Sound Systems

Cost - Which is more worth it

One of the deciding factors between whether to get a 5.1 or 7.1 system is price. If you’re looking to save money, you can snag a 5.1 surround sound package for a very fair price.

Of course, you get what you pay for, so these systems may not be sufficient for your needs. Top-of-the-line 5.1 sound systems from a top-of-the-line brand like Klipsch can run you over $6,000. This system will promise high definition, theater-quality sound and come with the receiver included.

If you’re planning to go with a 7.1 surround system, you can expect to pay at least $500 for a decent system. Obviously, this won’t get you a very good system. For a good 7.1 surround sound system with a receiver (although you don’t necessarily need a receiver as you’d know if you’ve read our guide), you can expect to pay over $1,000 and up to $13,000.

5.1 vs 7.1 Soundbar Uncompressed

  • 5.1 Soundbars: These soundbars offer crisp and detailed audio, including a subwoofer for well-rounded sound. They’re well-suited for standard-sized rooms, maintaining clarity in dialogue and music, and are ideal for a balanced audio experience without overwhelming the space.
  • 7.1 Soundbars: Featuring two additional channels, 7.1 soundbars provide a more layered and immersive audio experience. They excel in larger rooms, enhancing the depth and movement in soundtracks, particularly in action-packed movies or live concerts.

Overall, both 5.1 and 7.1 soundbars effectively handle uncompressed audio, but the 7.1 offers greater immersion and nuance, so if you are a high-quality sound enthusiast, 7.1 is the way to go.
