The included wireless 10-inch subwoofer and two SR2 surround speakers allow for flexible placement to suit different room layouts. The surrounds require either wall mounting or stands for optimal positioning, which are considerations for the final room setup. The system is finished in black, offering a neutral look that blends with most entertainment centers.
Performance and Features
Immersive Audio Performance
The core promise of the PolkAudio SR2 is certified Dolby Atmos and DTS:X cinematic surround sound. The 7.1.2 channel configuration, which includes two upfiring speakers in the soundbar, is engineered to produce overhead audio effects, creating a more three-dimensional listening experience. A key differentiator is Polk’s patented SDA (Stereo Dimensional Array) 3D technology. This is designed to deliver a super-wide soundstage, minimizing acoustic interference to make movies, TV, and music sound exceptionally immersive. Owner reviews frequently highlight the system’s ability to fill large rooms with detailed, captivating audio.
Voice Clarity and Bass
Dialogue clarity is a common challenge with home audio, which Polk addresses with its patented VoiceAdjust technology. This feature works with the integrated center channel speaker to boost vocal levels without affecting the balance of the rest of the soundtrack, ensuring clear conversation even during loud action scenes. For bass, the system includes a wireless 10-inch subwoofer that connects automatically upon powering on. It is designed to deliver deep, rumbling bass that can be placed anywhere in the room for optimal effect. The system also includes a Night Mode, which reduces bass and enhances voice levels for quieter late-night viewing.
Connectivity and Streaming
This system is built for a wireless entertainment ecosystem. It supports high-quality music streaming via built-in Wi-Fi with Chromecast built-in, Bluetooth, and Apple AirPlay 2. This allows users to stream directly from smartphones, tablets, or computers. For video sources, the soundbar features HDMI inputs with 4K/60 fps, HDR10, and Dolby Vision passthrough, ensuring high-quality video is delivered to the TV. This makes it a central hub for both audio and video components. The ability to create a multi-room audio solution is also a noted feature, adding to its versatility beyond TV sound.
Control and Presets
The system comes with a remote control for adjusting volume, selecting inputs, and toggling features like VoiceAdjust and Night Mode. It is also compatible with voice control for hands-free operation. Several preset sound modes are included, which optimize the audio profile for different content types such as movies, music, and sports, allowing users to quickly tailor the sound to their activity.
Setup, Support and Ownership
Setup is designed to be straightforward, with the wireless subwoofer and surround speakers intended to connect automatically. However, some owner feedback notes that initial pairing of these wireless components may occasionally require troubleshooting. The surround speakers need a power supply and benefit from strategic placement, which may involve wall mounting or stands not included in the primary bundle. The system’s larger footprint is best suited to bigger rooms. Polk provides a limited one-year warranty. Information regarding the frequency of firmware updates or long-term software support is not detailed in the available specifications.
What Owners Say

Many highlight the exceptional clarity of dialogue and the immersive, room-filling nature of the sound. Several users with experience in traditional high-power receiver setups have been impressed by how this system compares, noting it “punches above its weight class.” Positive remarks also mention stable wireless connectivity and the system’s reliability over extended use.
A smaller portion of reviews mention the value proposition relative to recent price adjustments.

FAQs
Does the PolkAudio SR2 truly produce overhead Dolby Atmos sound?
Yes, the system is certified for Dolby Atmos and DTS:X. It includes two upfiring speakers within the main soundbar unit that are specifically designed to bounce sound off the ceiling to create the perception of overhead audio effects, contributing to a more three-dimensional soundscape for compatible content.
How does the VoiceAdjust technology work?
VoiceAdjust is a patented Polk technology that works in conjunction with the system’s dedicated center channel speaker. It allows you to boost the volume level of dialogue and vocals independently from the rest of the audio mix. This means you can make conversations clearer without making background music or sound effects disproportionately louder.
Are the surround speakers and subwoofer truly wireless?
The audio connection from the main soundbar to both the subwoofer and the SR2 surround speakers is wireless, eliminating the need to run speaker wires across the room. However, each of the two surround speakers and the subwoofer require a separate power cord to be plugged into an electrical outlet for operation.
Can I use this system for music streaming without the TV on?
Absolutely. The PolkAudio SR2 has robust streaming capabilities via built-in Wi-Fi (supporting Chromecast and Apple AirPlay 2) and Bluetooth. You can stream music directly from your phone, tablet, or computer to the soundbar system independently, using it as a powerful wireless speaker for your entire music library or streaming services.
