Product information

Description

The Polk Audio Signa S4 is a 3.1.2 channel soundbar system engineered to deliver an immersive home cinema experience. Featuring advanced Dolby Atmos support, this system creates a 360-degree soundstage that brings movies, music, and gaming to life with cinematic clarity. The package includes a dedicated wireless subwoofer that provides deep, impactful bass, ensuring a balanced and powerful audio performance for any living space.

Advantages

This soundbar system excels by providing a true 3.1.2 channel configuration, which includes dedicated height channels to fully utilize Dolby Atmos technology for overhead sound effects. The inclusion of VoiceAdjust technology ensures that dialogue remains crisp and intelligible, even during intense action sequences. Furthermore, the wireless subwoofer offers flexible placement options, allowing users to position it anywhere in the room without the clutter of cables, while the system's low-profile design ensures it fits discreetly beneath most televisions without obstructing the screen or infrared sensors.

Suitable for

  • Enhancing home theater audio for movies and television shows
  • Immersive gaming experiences with 3D spatial audio
  • High-quality music streaming via Bluetooth
  • Improving dialogue clarity for news and talk programs

This system may not be suitable for users seeking a full surround sound experience with physical rear speakers, as it relies on virtualized processing for its surround effects. Additionally, it might be less ideal for very large, open-concept rooms where a more complex multi-speaker system would be required to fill the space effectively.

Key specifications

  • Audio channels: 3.1.2
  • Audio decoding: Dolby Atmos
  • Connectivity: Wired (HDMI eARC/ARC, Optical, Aux) and Wireless (Bluetooth)
  • Subwoofer: Separate wireless unit with 15 cm (5.9 inch) woofer
  • Tweeter size: 2.54 cm (1 inch)
  • Color: Black

To set up the system, connect the soundbar to your television using the provided HDMI cable via the eARC or ARC port for the best performance. If your TV lacks these ports, you can use the optical or auxiliary inputs. Once connected, the wireless subwoofer will automatically pair with the soundbar upon power-up. You can then use the included remote or your existing TV remote to adjust volume, select sound modes, and manage bass levels to suit your preferences.

What to consider before purchase

  • Ensure your TV has an HDMI eARC or ARC port to fully support Dolby Atmos functionality.
  • Verify that the physical dimensions of the soundbar fit your TV stand or wall-mounting space.
  • Consider the placement of the wireless subwoofer to ensure it has access to a power outlet.
For the best audio performance, place the subwoofer in a corner or near a wall to enhance bass resonance. Regularly update your TV firmware to ensure seamless communication between your television and the soundbar via HDMI.
