Buying Guide for the Best Arc Soundbar
Shopping for an arc soundbar can feel overwhelming with so many features and technical terms to consider. The key to finding the best soundbar for your home setup is to understand your needs—like the size of your room, the devices you’ll connect, and the type of audio experience you want. By learning what the main specifications mean and how they impact your listening, you can confidently compare models and make a choice that fits your lifestyle.Audio ChannelsAudio channels refer to how many separate paths sound travels through, such as 2.0, 3.1, 5.1, or even 7.1.2. More channels generally mean more immersive and surround-like audio. A basic 2.0 system provides simple stereo sound, suitable for smaller spaces or simple TV watching. A 3.1 setup adds a dedicated center channel for clearer dialogue, while 5.1 or greater incorporates rear and overhead speakers for effects, creating a theater-like environment. If you mostly watch TV or listen to music, a 2.0 or 3.1 system may be enough, but if you love watching movies, playing games, or want a more immersive feel, opt for a higher channel count that includes surround and height effects.
Dolby Atmos SupportDolby Atmos is a technology that creates 3D sound by placing audio in different virtual locations, even above your head. This makes movies and certain types of music more immersive and realistic. Some arc soundbars support this feature, while others do not. If you mainly watch regular TV or basic streaming, Dolby Atmos may not be essential. But if you enjoy cinematic experiences or have a streaming service that provides Atmos content, choosing a soundbar with this support can enhance your enjoyment.
Connectivity OptionsConnectivity refers to the ways you can connect the soundbar to your TV or other devices. Common options include HDMI ARC/eARC, optical audio, Bluetooth, and Wi-Fi. HDMI ARC/eARC typically provides the best sound quality and supports advanced features like Dolby Atmos, while optical is simpler but more limited. Bluetooth and Wi-Fi are useful for wireless streaming from your phone or tablet. For most users, having HDMI ARC/eARC is ideal for new TVs and modern setups. However, if your devices are older or you want to play music wirelessly, check for a variety of connectivity options that cover your needs.
Size and DesignThe size and design of a soundbar affect both how it looks and how it fits into your space. Soundbars come in different lengths and shapes—some are low-profile and wide, while others are more compact. Choosing the right size has both aesthetic and acoustic effects; a large soundbar often pairs well with big TVs and fills large rooms more efficiently, while smaller units are better for bedrooms or smaller living rooms. Always measure the available space and consider the look you want for your setup before picking one.
Subwoofer InclusionA subwoofer is a separate speaker dedicated to producing deep bass sounds, making action scenes and music feel punchier and more impactful. Some arc soundbars come bundled with an external subwoofer, while others have built-in bass speakers or offer the subwoofer as an optional add-on. If you enjoy movies with dramatic soundtracks, gaming, or music with lots of bass, getting a soundbar with a subwoofer will noticeably enhance your audio experience. If you have neighbors or prefer a more subtle sound, a soundbar without a subwoofer may be sufficient.
Smart FeaturesMany modern soundbars include smart features like voice assistants (Google Assistant, Alexa), app controls, or integration with smart home devices. These features let you control your soundbar with your voice, adjust settings via smartphone, or sync with other smart gadgets. If you like using smart tech in your home or want to adjust the soundbar without searching for a remote, look for those with built-in smart features. If you prefer simplicity, models without these extras may suit you better.
