Why Size Matters for Soundbars and TVs

When setting up a home theater system, size matters! Choosing the right size soundbar for your TV can make all the difference in your audio experience. A soundbar that is too small will not provide sufficient sound coverage, and a soundbar that is too large can overpower the room.

It’s essential to find the right balance between the size of the TV and the soundbar. Additionally, the placement of the soundbar on the TV is critical for optimal sound quality. Choosing the right size soundbar and positioning it correctly can enhance your viewing experience and allow you to enjoy seamless, high-quality audio from your favorite movies and TV shows.

Recommended Soundbar Sizes for 70 Inch TVs

As I mentioned, the soundbar size you choose for your 70-inch TV can significantly impact your viewing experience. Based on my research, I strongly recommend soundbars with a width of at least 45 inches to fully complement the larger screen of a 70-inch TV.

However, personal preference, budget, and room layout are essential factors when choosing the perfect size soundbar for your TV. Remember that an overly large soundbar may overcrowd your TV stand or wall mount, while a small one may not provide adequate sound quality. So, take your time to find the right balance and size that meets your needs.

Factors to Consider When Choosing a Soundbar Size

When choosing a soundbar size for your 70-inch TV, it’s essential to consider a few factors. First of all, you want to ensure that the soundbar’s length is similar to the width of your TV, preferably a few inches shorter.

Also, think about the placement of your TV and where you’ll be sitting about the soundbar. If you’re sitting far away, you may want to consider a larger soundbar or a system with multiple speakers to create a more immersive sound.

Additionally, don’t forget to consider your budget and what features are most important to you, such as the number of channels or compatibility with voice assistants. Considering these factors, you can choose the perfect soundbar for your 70-inch TV that provides excellent sound quality and complements your viewing experience.

Top Soundbars for VIZIO 70 Inch TV

I highly recommend the Vizio Elevate Sound Bar for anyone looking for the best soundbar for their Vizio 70-inch TV. With its unique design that automatically rotates to provide an immersive audio experience, this premium 5.1.4 setup offers an award-winning design with an accessible form.

However, if you’re looking for other options, the Sonos Beam (2nd Gen), Samsung HW-Q70T, Yamaha YAS-209, and LG SK9Y are also great. These soundbars offer excellent audio quality and easy connectivity with your Vizio TV. Ultimately, the best choice depends on your specific needs and preferences. Still, with any soundbars, you will surely enjoy a powerful and immersive audio experience that enhances your TV viewing experience.

1. Sonos Beam (2nd Gen)

I recommend the Sonos Beam (2nd Gen) soundbar as the top choice for a 70-inch TV. It has a discreet center channel for improved dialogue, and it also comes with Dolby Atmos technology for a truly immersive audio experience.

It seamlessly integrates with mounted TVs and even works as a standalone speaker. Controlling the Beam has never been easier with the Sonos app and Apple Airplay 2 compatibility. At a price point of €549, it’s an investment, but the impressive sound quality for its compact size is worth it.

2. Samsung HW-Q70T

I highly recommend the Samsung HW-Q70T soundbar as the perfect match for your 70-inch TV. This 3.1.2-channel soundbar comes with Dolby Atmos and DTS:X, which provides complete immersion and powerful 3D surround sound that fires from the front, side, and above.

Its wireless subwoofer also matches the size of a typical subwoofer, making it perfect for those who want to experience cinema-quality sound. Additionally, it comes with Wi-Fi and Bluetooth connectivity, making it easy to stream your music, podcasts, or audiobooks.

Overall, with its seamless compatibility with Samsung QLED TVs, powerful sound, and top-notch features, the Samsung HW-Q70T soundbar is worth considering for your 70-inch TV setup.

3. Yamaha YAS-209

Out of all the soundbars I’ve researched, the Yamaha YAS-209 seems to be an excellent option for a 70-inch TV. Its 2.1 setup and wireless subwoofer provide a robust, immersive sound that enhances TV, movies, and games.

Its built-in Alexa voice control and DTS Virtual:X virtual 3D surround sound add a convenient touch. In terms of size, the central soundbar unit is approximately 37 inches wide and 2.5 inches tall, making it easy to fit under several TVs without blocking the IR.

The Yamaha YAS-209 is a well-balanced soundbar that enhances your TV viewing experience significantly.

4. LG SK9Y

I have used the LG SK9Y soundbar, and while it may not have the most comprehensive sound profile, it still delivers decent audio quality. Its subwoofer measures 8.7″ x 15.4″ x 12.3″, making it an excellent fit for most living room setups.

However, if you have a 55-inch TV with legs close together, it might not fit between them. But don’t worry; plenty of other soundbars cater to all TV sizes. The Sonos Beam (2nd Gen) is an excellent choice for LG TVs, offering outstanding audio performance at a mid-range price.

Nevertheless, the LG SK9Y could still be a decent option if you want a cheaper alternative. Just make sure to evaluate all the factors before making a final decision.

5. Vizio SB36512-F6

I recommend the Vizio SB36512-F6 as one of the top soundbars for a 70-inch TV. It’s an affordable option with immersive listening thanks to its up-firing speakers and Dolby Atmos capability. The included wireless subwoofer may be smaller than expected, but it still adds a satisfying amount of bass to your audio experience.

Plus, the compact design won’t take up too much space in your living room. Overall, the Vizio SB36512-F6 provides excellent sound quality for its price point, making it a great addition to any entertainment setup.


When looking for the best soundbar for a 70-inch TV, it’s essential to consider the size of the soundbar and the TV, as well as factors such as sound quality and features—recommended soundbar sizes for a 70-inch TV range from around 45 to 60 inches, depending on personal preference.

Some top soundbars for VIZIO 70-inch TVs include the Sonos Beam, Samsung HW-Q70T, Yamaha YAS-209, LG SK9Y, and Vizio SB36512-F6. Depending on the soundbar, it may be necessary to have a subwoofer for optimal bass performance.

The average cost of a soundbar for a 70-inch TV can range from around $200 to $1000 or more, depending on brand and features.

What is size soundbar best for a 70-inch TV?

There’s no one-size-fits-all answer to finding the best soundbar for a 70-inch TV. However, there are some general guidelines that you can follow to get the most out of your audio experience.

Based on our research, we recommend finding a soundbar that is at least 60 inches wide to match the width of your TV. This allows maximum separation of the left and proper audio channels, resulting in a better sound quality overall.

Of course, the size of your room and personal preferences may come into play, but generally speaking, a soundbar at least 60 inches wide is an excellent place to start when pairing with a 70-inch TV.

How many channels should a soundbar have for a 70-inch TV?

In my experience, a soundbar with at least 2.1 channels is required for a 70-inch TV. A giant TV needs a more robust, immersive audio experience to match the stunning visuals. Additionally, having a subwoofer can enhance the overall sound quality, especially in terms of bass.

However, if you’re a true audiophile or want a movie theater-like experience, a soundbar with more channels, such as 5.1 or even 7.1, can provide a more surround sound experience. Ultimately, it comes down to personal preference and budget. Ensure the soundbar you choose is compatible with your TV and has the necessary input for your devices.

Is it necessary to have a subwoofer with a soundbar for a 70-inch TV?

In my experience, having a subwoofer with a soundbar for a 70-inch TV is unnecessary, but it can undoubtedly enhance the overall audio experience.

Some soundbars come with a built-in subwoofer, which can produce decent bass levels, but if you’re a real audiophile, adding a dedicated subwoofer can take your sound quality to the next level. Keep in mind that subwoofers can take up extra space, and they can be more expensive as well.

So, it’s really up to your personal preferences and budget. A good soundbar with or without a subwoofer can significantly improve your TV’s audio, especially when watching movies, TV shows, or video games.

Can I use any soundbar with a 70-inch TV?

I think it’s important to consider the soundbar’s size and quality with a 70-inch TV. While technically, you could use any soundbar with a 70-inch TV, ensuring that it will deliver the best possible audio experience for your viewing pleasure is essential.

Finding a soundbar that’s not too small or too big for your TV and has enough channels to provide a cinematic experience is critical.

Additionally, many soundbars come with a wireless subwoofer, which can make a massive difference in the sound quality, particularly for bass-heavy content like action movies or music. Choosing a soundbar for your 70-inch TV depends on personal preference and budget.

What is the average cost of a soundbar for a 70-inch TV?

When finding a suitable soundbar for your 70-inch TV, the cost is a factor. On average, you can expect to spend anywhere from $100 to $500 on a soundbar for a 70-inch TV. Of course, the price can vary depending on the brand and features you’re looking for.

While it might be tempting to opt for the cheapest option available, it’s important to remember that quality can also come with a higher price tag.

However, great soundbar options for those on a budget, like the TCL Alto 6 or JBL Bar 5.1, can provide excellent sound without breaking the bank. Ultimately, it’s all about finding the right balance between cost, quality, and the features you need for your TV setup.
