When it comes to upgrading your TV's audio in 2024, two standout options are the Polk Audio MagniFi Max AX and the LG S90TR. Both launched in late 2023, representing the latest in home audio technology. Let's explore how these systems compare and which might be right for your setup.
Modern soundbars have come a long way from the simple stereo bars of a few years ago. They now offer complex audio processing, multiple speakers, and the ability to create immersive sound that seems to come from all around you. The key technology here is Dolby Atmos, which adds height channels to create a three-dimensional sound bubble - imagine hearing a helicopter actually moving overhead in your favorite action movie.
Both the Polk MagniFi Max AX ($799) and LG S90TR ($799) support this technology, but they take different approaches to delivering it.
The fundamental difference between these systems lies in their channel configuration. The Polk offers a 3.1.2 setup, which means:
The LG provides a more extensive 7.1.3 configuration:
This difference isn't just about numbers - it significantly impacts how immersive the sound experience can be. The LG's additional channels create a more complete sphere of sound, particularly noticeable in larger rooms where sound has more space to travel and reflect.
The Polk MagniFi Max AX excels at dialogue clarity, thanks to its VoiceAdjust technology. This is particularly helpful for everyday TV watching, where understanding conversation is crucial. The system's "Night Mode" is also impressive, automatically balancing sound levels so you won't wake the household during late-night viewing.
The LG S90TR takes the lead for movie watching, especially in dedicated home theater settings. Its additional channels create a more convincing surround sound effect, and the third height channel adds extra precision to overhead sounds. The system's AI room calibration (which automatically adjusts sound based on your room's acoustics) makes a noticeable difference in getting the best possible performance.
Both systems handle music well, but in different ways:
Modern soundbars are expected to be more than just speakers - they're entertainment hubs. Here's how these systems compare:
The setup experience differs significantly between these systems:
The Polk takes a straightforward approach - connect the HDMI cable, plug in the subwoofer, and you're mostly done. It's ideal for users who want good sound without complex configuration.
The LG requires more setup time but offers more refinement. The AI room calibration process takes about 5 minutes but delivers noticeably better sound. The additional speakers need careful placement for optimal performance.
At the same $799 price point, the decision comes down to your priorities:
The Polk MagniFi Max AX offers:
The LG S90TR provides:
Consider your room size first. In smaller rooms (under 200 square feet), the Polk's simpler setup might actually work better, as complex surround systems can create muddied sound in tight spaces. The LG shines in medium to large rooms where its additional channels can create a more encompassing sound field.
Think about your primary use case:
Both systems represent current technology, but the LG's more advanced feature set might provide better future-proofing. Its support for 4K/120Hz passthrough and more sophisticated processing suggests it might handle upcoming audio formats and features better.
For most users, the LG S90TR represents better value, offering more features and better overall performance at the same price point. However, the Polk MagniFi Max AX remains a strong choice for those prioritizing simplicity and dialogue clarity.
Remember: The best soundbar is the one that fits your specific needs and room setup. Don't be swayed just by feature lists - consider how you'll actually use the system in your space.
