When it comes to home entertainment systems, soundbars have become an increasingly popular choice for their sleek designs, ease of use, and impressive audio quality. However, one question that often arises among soundbar enthusiasts is whether or not an external amplifier is necessary to enhance the listening experience. In this article, we’ll delve into the world of soundbar amplification, exploring the ins and outs of this topic and helping you determine whether an external amp is right for you.
Understanding Soundbar Amplification
Before we dive into the nitty-gritty of external amplifiers, it’s essential to understand how soundbars work. A soundbar is essentially a compact, all-in-one speaker system that combines multiple drivers, amplifiers, and signal processing technology into a single unit. The built-in amplifier is designed to power the drivers, producing a balanced and immersive audio experience.
Most soundbars come with a built-in amplifier that’s specifically designed to match the speaker’s impedance and power requirements. This amplifier is usually a Class D amplifier, which is a type of switching amplifier that’s highly efficient and compact. Class D amplifiers are well-suited for soundbars because they provide a good balance between power output and energy efficiency.
Types of Soundbars and Their Amplification Needs
Not all soundbars are created equal, and their amplification needs can vary depending on the type and design. Here are a few common types of soundbars and their amplification requirements:
- Basic Soundbars: These are entry-level soundbars that usually come with a built-in amplifier that’s sufficient for small to medium-sized rooms. They often have a power output of around 20-50 watts per channel.
- Soundbar Systems with Subwoofers: These soundbars come with a separate subwoofer that requires more power to produce deep bass notes. In this case, the built-in amplifier may not be sufficient, and an external amplifier might be necessary to drive the subwoofer.
- High-End Soundbars: These premium soundbars often come with more powerful built-in amplifiers that can produce higher sound pressure levels. However, they may still benefit from an external amplifier to further enhance the audio quality.
Benefits of Using an External Amplifier with a Soundbar
While a soundbar’s built-in amplifier can provide good sound quality, there are several benefits to using an external amplifier:
- Increased Power Output: An external amplifier can provide more power to the soundbar, resulting in higher sound pressure levels and a more immersive listening experience.
- Improved Dynamic Range: An external amplifier can help to improve the dynamic range of the soundbar, allowing for more nuanced and detailed sound reproduction.
- Reduced Distortion: An external amplifier can help to reduce distortion and noise, resulting in a cleaner and more accurate sound.
- Flexibility and Upgradability: An external amplifier can provide more flexibility and upgradability options, allowing you to upgrade your sound system in the future.
When to Use an External Amplifier with a Soundbar
So, when should you consider using an external amplifier with your soundbar? Here are a few scenarios:
- Large Rooms: If you have a large room or an open-plan living area, an external amplifier can help to increase the soundbar’s power output and fill the space with sound.
- High-Volume Listening: If you like to listen to music or watch movies at high volumes, an external amplifier can help to provide more power and reduce distortion.
- Subwoofer Integration: If you have a soundbar system with a separate subwoofer, an external amplifier can help to drive the subwoofer and produce deeper bass notes.
Choosing the Right External Amplifier for Your Soundbar
If you’ve decided to use an external amplifier with your soundbar, here are a few things to consider when choosing the right one:
- Power Output: Look for an amplifier that can provide sufficient power to drive your soundbar. A good rule of thumb is to choose an amplifier that can provide at least 50 watts per channel.
- Impedance Matching: Make sure the amplifier is impedance-matched to your soundbar. This will ensure that the amplifier can provide the correct amount of power to the soundbar.
- Signal Processing: Consider an amplifier with built-in signal processing features such as EQ, compression, and limiting. These features can help to enhance the sound quality and provide more flexibility.
- Connectivity Options: Look for an amplifier with multiple connectivity options such as HDMI, optical, and analog inputs. This will ensure that you can connect your soundbar and other devices easily.
Popular External Amplifier Options for Soundbars
Here are a few popular external amplifier options for soundbars:
- Yamaha A-S801: A high-end integrated amplifier that provides 100 watts per channel and features built-in signal processing and multiple connectivity options.
- Denon AVR-X3600H: A home theater receiver that provides 105 watts per channel and features built-in signal processing, multiple connectivity options, and support for Dolby Atmos and DTS:X.
- Onkyo A-9150: A high-end integrated amplifier that provides 90 watts per channel and features built-in signal processing, multiple connectivity options, and support for Dolby Atmos and DTS:X.
Conclusion
In conclusion, whether or not you need an external amplifier for your soundbar depends on several factors, including the type of soundbar, the size of your room, and your listening preferences. While a soundbar’s built-in amplifier can provide good sound quality, an external amplifier can offer several benefits, including increased power output, improved dynamic range, and reduced distortion. By choosing the right external amplifier and considering factors such as power output, impedance matching, and signal processing, you can enhance your soundbar’s performance and enjoy a more immersive listening experience.
| Soundbar Type | Amplification Needs |
|---|---|
| Basic Soundbars | Built-in amplifier sufficient for small to medium-sized rooms |

By considering these factors and choosing the right external amplifier, you can take your soundbar’s performance to the next level and enjoy a more immersive and engaging listening experience.
What is a soundbar and how does it work?
A soundbar is a type of loudspeaker that produces a wider sound field, making it ideal for home theaters and music listening. It works by using multiple drivers, such as tweeters and woofers, to produce a wide range of frequencies, creating a more immersive audio experience. Soundbars are designed to be compact and easy to set up, making them a popular choice for those who want to enhance their TV’s audio without the hassle of a full home theater system.
Soundbars can be connected to a TV using various methods, including HDMI, optical, and Bluetooth. They often come with built-in amplifiers, which power the drivers and produce the sound. However, some soundbars may not have enough power to produce the desired level of sound quality, which is where an external amplifier comes in.
What is an external amplifier and how does it work?
An external amplifier is a separate device that is designed to increase the power output of a soundbar. It works by taking the audio signal from the soundbar and amplifying it, allowing the soundbar to produce a louder and more detailed sound. External amplifiers can be connected to a soundbar using various methods, including RCA cables and speaker wire.
External amplifiers can be particularly useful for soundbars that are not powerful enough to fill a large room or produce the desired level of bass. They can also be used to add more channels to a soundbar, such as a subwoofer or rear speakers, to create a more immersive audio experience.
Do I need an external amplifier for my soundbar?
Whether or not you need an external amplifier for your soundbar depends on several factors, including the size of your room, the type of soundbar you have, and the level of sound quality you want to achieve. If you have a small room and a soundbar with a built-in amplifier, you may not need an external amplifier. However, if you have a large room or want to produce a more detailed and immersive sound, an external amplifier may be necessary.
It’s also worth considering the type of soundbar you have. Some soundbars are designed to be more powerful than others, and may not require an external amplifier. However, if you have a soundbar that is not producing the desired level of sound quality, an external amplifier may be a good option.
