10 Best Dolby Atmos Soundbar Under 500 2026 in the United States

The Polk Audio MagniFi Max AX SR is a 7.1.2 channel soundbar system designed to deliver immersive Dolby Atmos and DTS:X surround sound at a price point that fits under $500. It includes a wireless 10" subwoofer and two surround speakers, which help fill your room with rich, three-dimensional audio, including overhead sounds that enhance movies and shows. The soundbar supports multiple connectivity options, including HDMI eARC, optical input, Bluetooth, Wi-Fi, Apple AirPlay 2, and Chromecast, making it easy to connect to your TV and stream music from various devices. Polk’s patented VoiceAdjust technology is a helpful feature that boosts dialogue clarity without overpowering other sounds, ideal for watching TV without missing what people say.

The build is sleek and not overly bulky, fitting well under most TVs, and it comes with wall-mounting options if you prefer. Setup is straightforward, and the included remote and voice control compatibility add convenience. While the system provides clear and powerful sound, its 200-watt output might not fill very large rooms as impressively as higher-end models. Also, it’s not water-resistant, so it’s best kept indoors and away from moisture. The subwoofer, although wireless, requires power from an outlet, which may limit placement flexibility.

This system is an excellent choice for users looking to upgrade their home TV sound with a true Dolby Atmos experience without spending a fortune. It suits those who want easy streaming and solid surround sound for movies, TV, and music but don’t require the absolute top-tier power or advanced smart home integration beyond basic voice assistants.

The ULTIMEA Poseidon D80 is a robust choice for a Dolby Atmos soundbar under $500. It features a 7.1 channel setup, which includes 8 high-performance drivers and a 6.5-inch wireless subwoofer, offering an impressive and immersive audio experience. The inclusion of Dolby Atmos technology enhances the 3D soundscape, making movies and shows more engaging. Its SurroundX System and 360° Aural Spatial Localization further ensure that the audio reaches you from all directions, adding to the surround sound effect.

With 4 wired surround speakers, it does require some setup but promises a comprehensive home theater experience once arranged correctly. The soundbar supports various connectivity options like Bluetooth, HDMI with eARC, optical, and AUX, making it compatible with many devices, including older models. The smart control via the ULTIMEA app allows for convenient updates and customization, including 121 EQ presets and 6 tailored audio modes, catering to different genres and preferences.

However, it's worth noting that the Poseidon D80 does not support DTS decoding, which might be a limitation for some users. The modern, tech-savvy design is complemented by a user-friendly interface with both remote and app controls. At 21 pounds, it is relatively heavy and may require a sturdy setup for wall mounting. For users looking for a high-quality, immersive sound system with advanced features like Dolby Atmos within a budget, the ULTIMEA Poseidon D80 is a compelling option, though the wired speakers and lack of DTS support are points to consider.

The Polk Audio MagniFi Max AX is a strong contender in the Dolby Atmos soundbar category under $500, offering a rich 5.1.2 channel setup with 11 drivers including up-firing speakers for immersive height effects. This setup effectively delivers surround sound with certified Dolby Atmos and DTS:X, which enhances movie and music experiences with a cinematic feel. Its standout feature is Polk’s patented VoiceAdjust technology, which makes dialogue much clearer without sacrificing background sound, a big plus for TV shows and sports. The included 10-inch wireless subwoofer adds deep, satisfying bass that pairs well with the soundbar without taking up much space.

Connectivity is versatile, supporting Wi-Fi, Bluetooth, Apple AirPlay 2, Chromecast, Spotify Connect, and Alexa, making it easy to stream music directly from many devices. The soundbar is reasonably sized and designed for tabletop or wall mounting, fitting comfortably in most living rooms. Setup is straightforward, which helps users get started quickly.

On the downside, it is not water-resistant and its 200-watt power output, while decent, may not fill very large rooms with strong volume. Also, the subwoofer, though wireless, connects via a wired power source, which could limit placement options slightly. This soundbar is well-suited for those looking for immersive home theater sound with good bass and clear dialogue, especially if streaming and smart device compatibility are important.
