10 Best Dolby Atmos Soundbar Under 500 2025 in the United States

The Polk Audio Signa S4 Sound Bar stands out in the under $500 Dolby Atmos soundbar category with its impressive audio performance and user-friendly features. With a 3.1.2 channel setup, it delivers immersive 3D sound thanks to its up-firing speakers, which utilize Dolby Atmos technology to create a height effect. Its dedicated subwoofer enhances the bass, providing a rich and full sound experience, making it suitable for movie enthusiasts and gamers alike.

One of the key highlights is its exclusive VoiceAdjust technology, allowing users to customize dialogue levels for clearer speech, which is particularly beneficial for those who watch movies or shows with extensive dialogue. The sleek, ultra-slim design of the soundbar (at just 2.36 inches tall) ensures it can fit seamlessly in most setups without obstructing the TV screen or remote sensor, making it a good choice for various room sizes.

Setting up the Signa S4 is a breeze, requiring only a single cable connection to your TV, which is great for those who prefer a hassle-free installation. Plus, its compatibility with 8K, 4K, and HD TVs means it's future-proof for the latest technology. The built-in Bluetooth functionality allows for easy streaming from devices, broadening its appeal for music lovers. However, while the sound quality is commendable, some users may find that the bass might not be deep enough for those who prefer a thumping sound experience. Additionally, while the connectivity options are plentiful with HDMI (eARC), optical, and analog inputs, it lacks advanced features found in higher-end models, like multi-room audio support. The Polk Audio Signa S4 Sound Bar is a solid option for anyone seeking a high-quality audio upgrade for their home entertainment system without breaking the bank, particularly benefiting movie watchers and general users looking for a straightforward setup with good sound quality.

The JBL Bar 9.1 is a solid choice for anyone seeking an immersive home theater experience without breaking the bank. Its standout feature is the built-in Dolby Atmos and DTS: X decoding, which enhances audio for a surround sound experience. With an impressive total output of 820 watts and a hefty 300-watt, 10-inch powered subwoofer, it delivers deep, resonant bass that can fill a room. The detachable, battery-powered surround speakers add to the convenience by allowing you to enjoy real surround sound without the hassle of wires, making it great for smaller spaces or casual setups.

In terms of connectivity, the JBL Bar 9.1 offers several options, including HDMI, Bluetooth, Wi-Fi, and optical connections, ensuring compatibility with most devices. The package includes all necessary components like cables and wall-mount brackets, which is a nice touch for users who want a quick setup.

There are some drawbacks to consider. While the wireless surround speakers are convenient, some users may find the battery life to be limited, requiring frequent recharging. The size of the soundbar and subwoofer may also be a concern for those with limited space, as it’s relatively large compared to some compact models. Additionally, the soundbar's performance can vary depending on room acoustics, although it does include built-in calibration to help optimize sound.

For those who prioritize high-quality audio in a home entertainment setup, the JBL Bar 9.1 strikes a commendable balance between performance and price. It’s especially well-suited for movie lovers and gamers looking for an enhanced immersive experience, though users should keep in mind their space and charging needs when considering this soundbar.
