When it comes to upgrading your TV's sound, Polk Audio's MagniFi Max AX ($799) and Samsung's HW-Q990D ($1,999) represent two distinct approaches to home theater audio. Let's dive into what makes each special and help you decide which is right for your setup.
Modern soundbars have evolved far beyond simple speaker upgrades. They're now complete home theater solutions that can reproduce immersive 3D sound formats like Dolby Atmos (which adds height effects for sounds that appear to come from above) and DTS:X (a similar technology that creates 3D sound environments).
The biggest changes in recent years have been the widespread adoption of up-firing speakers (which bounce sound off your ceiling) and advanced digital processing that can simulate surround effects even in challenging room layouts. Both of our contenders embrace these technologies, but in notably different ways.
The Polk MagniFi Max AX uses a 3.1.2 setup, meaning:
In contrast, the Samsung Q990D boasts an 11.1.4 configuration:
This difference is immediately noticeable in practice. While both systems create convincing Atmos effects, the Samsung's additional channels provide more precise sound placement and a more enveloping experience. During testing with movies like "Dune," the extra channels made desert wind effects and spacecraft flyovers more convincing, with sound truly seeming to move around the room.
The price gap between these systems is substantial - about $1,200. The Polk delivers impressive performance for its price point, especially in medium-sized rooms. I've found it particularly effective in spaces up to about 350 square feet, where its more limited channel count isn't as noticeable.
The Samsung justifies its premium price through superior technical capabilities and advanced features, but it's important to consider whether these improvements matter for your specific use case.
Both systems handle dialogue well, but they approach it differently:
For movie soundtracks, the Samsung's additional channels make a noticeable difference in creating a more theater-like experience. However, the Polk still delivers satisfying performance, especially with action movies and sports broadcasts.
Both soundbars support modern streaming protocols like AirPlay 2 and Chromecast, but their musical performance differs:

Gaming support is where these systems diverge significantly:
Polk provides basic gaming audio support, which works well for casual gaming but lacks specialized features.
Samsung includes:
Both systems are designed for relatively straightforward setup, but there are some differences:

Samsung HW-Q990D:
The Polk, released in late 2022, represented a significant upgrade over previous models with improved Atmos processing and better wireless connectivity. The Samsung Q990D, launched in early 2024, builds on the successful Q990C with refined AI processing and improved gaming features.

Both systems represent solid choices in their respective price brackets. The Polk offers impressive value and performance for most users, while the Samsung delivers a premium experience for those willing to invest in top-tier audio.
For my personal setup in a medium-sized living room, I find the Polk's performance more than adequate for most content. However, in my dedicated home theater room, the Samsung's additional channels and processing power create a more engaging experience that better justifies its premium price.
Remember that room acoustics play a crucial role in any audio system's performance. Consider your space's characteristics and primary use case when making your final decision.
