Looking to upgrade your TV's audio without filling your room with speakers? Today we're comparing two compelling premium soundbars - the Polk Audio MagniFi Max AX ($799) and Sony HT-A8000 BRAVIA Theater Bar 8 ($698). Both aim to deliver theater-like sound from a sleek package, but they take different approaches to get there.
Today's premium soundbars are a far cry from the basic stereo units of a decade ago. They now pack sophisticated audio processing, multiple speakers, and upward-firing drivers that bounce sound off your ceiling to create immersive 3D audio effects. This technology, combined with formats like Dolby Atmos (which allows sound to be precisely placed anywhere in a virtual 3D space), can create surprisingly convincing surround sound from a single bar.
The Polk MagniFi Max AX, released in late 2022, excels at pure volume and impact. Its included wireless subwoofer delivers room-filling bass that you can feel during explosive movie scenes. In larger spaces (think open-concept living rooms over 300 square feet), this extra power really helps maintain clarity and impact throughout the room.
The Sony HT-A8000, which debuted in 2021, takes a more nuanced approach. While it can't quite match the Polk's raw volume, it delivers noticeably clearer dialogue and more precise placement of sound effects. Sony's advanced room correction technology analyzes your space and adjusts the audio accordingly, resulting in more natural sound that seems to come from all around you rather than just the front of the room.
In practical use, these differences become clear when watching movies. During a recent viewing of "Dune," the Polk's powerful bass made sandworm scenes genuinely thunderous, while its high volume capability ensured even quiet dialogue remained clear. However, the Sony created a more convincing sense of being surrounded by swirling sand storms, with superior vertical sound movement thanks to its more sophisticated height channels.
The Polk MagniFi Max AX includes a wireless subwoofer in its $799 price tag, making it a complete solution out of the box. The Sony HT-A8000 requires purchasing a separate subwoofer (starting around $400) to achieve similar bass performance, pushing the total system cost significantly higher.
Both manufacturers have provided firmware updates since release:
Both soundbars offer comprehensive connectivity:
The Sony adds tight integration with BRAVIA TVs, allowing the TV's speakers to work in harmony with the soundbar as an additional center channel. The Polk offers slightly better multi-room audio support through its wider compatibility with various streaming platforms.
In a dedicated home theater setting, a few factors become particularly important:
Both support all major formats:
The Sony has a slight edge for gaming thanks to HDMI 2.1 features like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM), which help maintain smooth gameplay and minimize input lag.

Choose the Sony HT-A8000 if:
Both soundbars represent excellent choices in the premium segment, but they serve different users best. The Polk offers tremendous value and impact, especially in larger spaces, while the Sony delivers more refined sound and superior processing, particularly when paired with other Sony components.
For most users, I'd recommend the Polk MagniFi Max AX as the better value, thanks to its included subwoofer and excellent performance-to-price ratio. However, if absolute sound quality is your priority and budget allows for a separate subwoofer, the Sony HT-A8000 creates a more convincing immersive audio experience.
Remember that room acoustics play a huge role in any audio system's performance. If possible, try to audition these systems in person or purchase from a retailer with a good return policy to ensure you're happy with your choice in your specific space.
