With reliable connectivity, average latency, a fairly wide soundstage, and EQ sound customizations, the budget Polk Audio SIGNA S2 delivers good value for movie fans. However, the lack of Atmos support, underwhelming sub-bass, and uneven bass and treble lacks serious immersion.

Product Snapshot

Overview

The Polk Audio Signa S2 is an entry-level speaker system that was first launched in late 2018. It ships as a soundbar and a subwoofer, and since they’re wireless, setting them up is very easy to do.

Its subwoofer creates a decent bass output, but not thunderous, so for users who need that rumble when watching movies, some of the picks in our best speaker list might be worth looking into.

The Signa S2 doesn’t support Dolby Atmos, but its soundstage is good enough to accurately depict directional sounds when watching movies or TV. The best soundbars also have Bluetooth and Wi-Fi connectivity, but the Signa S2 can only connect to devices through Bluetooth.

Its port selection is limited to one Optical Audio In, one HDMI ARC port, and one AUX port, but it ships with a HDMI cable and a Digital Optical Cable for added convenience.

Consensus

our Verdict

The Polk Audio SIGNA S2 comes with a wireless subwoofer and connects reliably with HDMI ARC and Optical but lacks Full HDMI. While audio is crackle-free, tested latency performance could be better for video streaming (83ms via ARC and 75ms via Optical).

The soundstage is slightly wider than the bar, but sounds come from the front rather than immersing you from the sides, and the 2.1-channel setup doesn’t support Atmos.

Bass and treble are heightened but aren’t correctly balanced, and the underwhelming sub-bass means sounds lack satisfying thumps. And while the compact remote enables EQ adjustments, the bar doesn’t sport a protective grill, and the subwoofer’s low-grade exterior isn’t durable.

Lastly, input commands are responsive, and EQ presets offer quick sound customization, but there’s no app for accessing controls.

Reason to Buy

  • Good wired and wireless connectivity
  • No audio disturbances
  • Average latency performance
  • Fairly wide soundstage
  • Sound customization with EQ presets

Reason to Avoid

  • Heightened bass and treble are not balanced well
  • Subpar stereo surround
  • No Atmos support
  • Less extended sub-bass
  • No protective grill
  • Subwoofer made of cheap material
  • No app

The Polk Audio Signa S2 consists of a 2.1-channel setup, while the Polk Audio MagniFi MAX SR is a 5.1-channel sound system. This means that the MAX SR comes with two satellite channels that are not present on the S2. The MAX SR offers better wired connectivity options since it has three Full HDMI ports, while the S2 has none. See what else the MAX SR has to offer by reading through our Polk Audio MagniFi MAX SR review.

The Polk Audio Signa S2 has a dialogue enhancement feature that is missing on the JBL Bar 5.1 Surround. It also ships with a Digital Optical Cable that is not included with the JBL soundbar. In contrast, the JBL soundbar consists of a room correction feature that you won’t get with the Signa S2 and two HDMI ports that are also missing on the S2.

The Polk Audio Signa S2 features EQ presets, unlike the Sonos Arc, and it also ships with a subwoofer, which is not standard with the Sonos Arc. Still, the Sonos Arc offers a broader soundstage courtesy of its 5.0.2 channel setup, which is superior to the S2’s 2.1 channel setup.
