The Signa S4 pairs a low-profile 3.1.2 sound bar with a wireless 5.9 in subwoofer to deliver an expansive soundstage and deeper bass than most built-in TV speakers. Its single-cable setup and Polk's VoiceAdjust and BassAdjust controls make it an immediately usable upgrade for living rooms and small home theaters where clear dialogue and room-filling audio matter most.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDolby Atmos 3.1.2:\u003c\/strong\u003e Up-firing elevation speakers create height channels for a more immersive, over-the-head sense of space in movies and games.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7-driver array:\u003c\/strong\u003e Dedicated center channel and racetrack mid drivers deliver clearer dialogue and fuller midrange presence for voices and instruments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5.9 in wireless subwoofer:\u003c\/strong\u003e Adds deeper, physical bass impact that expands the overall soundstage beyond what the slim bar alone can achieve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoiceAdjust technology:\u003c\/strong\u003e Lets listeners raise vocal clarity without altering the rest of the soundtrack, improving intelligibility for TV and dialogue-heavy content.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBassAdjust control:\u003c\/strong\u003e Synchronizes bass level between bar and sub so users can tame or emphasize low end easily for different content or rooms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact, low-profile design:\u003c\/strong\u003e At about 2.36 in tall the bar fits under most TVs without blocking the IR sensor, whether wall-mounted or on a shelf.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Signa S4 is best for people who want a clear, appreciable step up from TV speakers with minimal setup time; streamers, casual movie watchers, and gamers using 4K or 8K TVs will find it especially convenient because it works with modern HDMI eARC connections and pairs quickly over Bluetooth for music.
