When it comes to upgrading your TV's audio, soundbars have become the go-to solution for many homes. Today, we're comparing two distinct options: the entry-level Polk Audio Signa S4 ($269) and the premium Samsung HW-Q990D ($1,298). Let's explore how these systems stack up and help you decide which might be right for your setup.
Today's soundbars have evolved far beyond simple stereo speakers. They now incorporate sophisticated audio processing, wireless connectivity, and immersive sound technologies like Dolby Atmos, which adds height channels to create a three-dimensional sound field. The difference between entry-level and premium systems often comes down to how effectively they can recreate this immersive experience.
Since the Polk S4's release in 2021, we've seen significant advances in room correction technology and wireless audio. The newer Samsung Q990D (released 2023) incorporates these developments, offering features like SpaceFit Sound Pro that automatically adjusts audio based on your room's acoustics - something missing from the Polk.
The Polk Signa S4 uses a 3.1.2 channel configuration, meaning:
This setup includes seven drivers total, with dedicated tweeters and mid-range speakers handling different frequency ranges. The wireless subwoofer uses a 5.9-inch driver for bass.
The Samsung Q990D delivers an 11.1.4 configuration:
With 22 total drivers, including:
The Polk S4 delivers surprisingly good performance for its price point. The dedicated center channel ensures clear dialogue, while the upward-firing speakers create a basic Atmos effect. However, without rear speakers, surround effects are simulated through clever processing.
The Samsung Q990D operates on a different level entirely. Its true surround sound creates a bubble of audio that places you in the center of the action. During testing, movies like "Dune" showcase the system's ability to move sound seamlessly between speakers, creating a truly cinematic experience. The additional channels allow for more precise sound placement and better separation between effects.

The Samsung Q990D requires more planning. You'll need power outlets for the main bar, subwoofer, and two rear speakers. However, the additional setup complexity delivers a more complete home theater experience. The SpaceFit Sound Pro feature helps optimize performance for your specific room.

The Samsung HW-Q990D ($1,298) is significantly better for movies due to its true surround sound setup with rear speakers and four height channels. While the Polk Signa S4 ($269) provides good movie performance for its price, it can't match the immersive experience of the Q990D's 11.1.4 channel configuration.
Yes, the Polk Signa S4 provides excellent value for a basic home theater setup. Its 3.1.2 channel configuration with Dolby Atmos support delivers good dialogue clarity and basic surround effects that will satisfy most users upgrading from TV speakers.
The Samsung Q990D offers substantially better performance with true surround sound, more powerful bass, and advanced features. However, at nearly 5x the price of the Polk S4, it's a significant investment that makes sense primarily for dedicated home theater enthusiasts.
The Polk Signa S4 is ideal for apartments due to its compact size, simple two-piece setup, and adjustable bass levels. The Samsung Q990D, while more powerful, requires more space and multiple power outlets for its rear speakers.
While the Polk S4 simulates surround effects from the front, true surround sound requires rear speakers like those included with the Samsung Q990D. The difference is noticeable, but many users find front-only systems satisfactory.
The Samsung Q990D delivers superior Dolby Atmos performance with four height channels and more precise sound placement. The Polk S4 provides basic Atmos effects through two up-firing speakers, which is good for entry-level but not as immersive.
Both soundbars are compatible with any TV through HDMI eARC or optical connections. However, the Samsung Q990D offers additional features when paired with Samsung TVs, like Q-Symphony integration.
The Samsung Q990D is significantly better for gaming with its HDMI 2.1 support, dedicated gaming mode, and true surround sound for positional audio. The Polk S4 provides basic gaming audio but lacks gaming-specific features.
The Polk S4 offers easier setup with just two pieces to connect. The Samsung Q990D requires more setup time with its rear speakers and subwoofer, but includes automatic room calibration to optimize performance.
The Polk S4 works well in small to medium living rooms up to 300 square feet. The Samsung Q990D is better suited for medium to large spaces up to 800 square feet and performs best in dedicated viewing rooms.
The Samsung Q990D delivers superior music performance with better clarity, deeper bass, and more precise stereo imaging. However, the Polk S4 provides satisfactory music playback for casual listening.
The Polk Signa S4 offers excellent value at $269 for basic home theater use. The Samsung HW-Q990D at $1,298 is worth the investment only if you want premium performance and have a dedicated viewing space.
