Five Decades of Engineering the Perfect Home Theater SoundSigna S4 was designed in our Acoustic Research and Development center outside Baltimore, MD by the speaker experts at Polk. We've leveraged over 50 years of American hi-fi loudspeaker engineering so Signa S4 will deliver the thunderous, crystal clear, cinematic surround sound experience you've always dreamed of in your home - but at a value you could only imagine. |
True Dolby Atmos Sound Bar SystemSigna S4 is Dolby Atmos Certified to immerse you in 360 degrees of surround sound. The difference between regular surround sound and Dolby Atmos Certified sound is that it provides a true 3D sound experience by the additional playback of audio on height channels. From added ambience in music to special effects flying overhead, Signa S4 provides an incredibly realistic sound environment. And when you playback standard audio through Signa S4, it can be upmixed to create a virtual Atmos experience. |
VoiceAdjust - Hear Every WordTired of riding the volume control to hear the dialogue during quiet scenes? Have trouble picking out voices when the bass kicks in? Polk's VoiceAdjust was designed to make sure that you hear every word. This patented technology combines with Signa S4's dedicated center channel to allow you to raise the volume of only the voices, making them clear and easy-to-understand, while leaving the rest of the soundtrack untouched. |

---|---|---|
Customizable Sound – Music, Movie, Night ModesLate night binge-watching session? Don’t worry about waking your family or neighbors. With Night Mode, one button lowers the bass while increasing VoiceAdjust so you can hear every word, without raising the master volume. Plus, one-button, preset sound modes optimize the Signa S4 so you can have the best sonic experience for movie watching and music listening. |
Wireless Subwoofer for Effortless BassSigna S4’s powerful wireless subwoofer provides the deep, effortless bass that Polk is famous for, at a level of loudness that’s surprising for its size. The subwoofer connects automatically on start up and can be conveniently placed nearly anywhere in the room. Put it up front or in the corner for maximum impact or place it behind the couch and feel the rumble. |
Sets Up In SecondsSet up is easy: simply connect the included HDMI or optical cable (or aux-in for older TVs) for the ultimate sound quality for any TV – even the latest 8K Ultra-HD TVs. Signa S4 is pre-programmed to work with most TV remotes, and it quickly pairs to your mobile device via Bluetooth to stream your favorite music. Lastly, Signa S4’s low-profile design won’t block your TV or your remote and can also be wall-mounted for flexible placement. |

Customers like the sound quality of the speakers. They say it has a bass boost to enrich the sound, the bass that comes out of the subwoofer is incredible, and the sound is clear. They also say the external speaker is clearer and does not buzz like the TV. The mode is good for late night listening with the sound turned down so that others are not bothered by the sound.

It is also easy to use. There are various adjustments that can be made with the sound bar remote, but once these were made we only use the TV remote. The sound bar appears to go into sleep mode when the TV is off and comes back on when the TV is turned on. It is compatible with Dolby 2.1 content, but it cannot be upgraded with additional speakers.
There are five inconspicuous buttons on the top of the sound bar: on/off, source selection, Bluetooth on/off, volume down, and volume up. Bluetooth is used for playing sound from other sources like a smart phone. These buttons also appear on the sound bar remote along with other buttons for mode selections. There are three sound buttons: Movie, Night, and Music. We use the Movie mode mostly as it “expands” the soft and loud sounds as if in a movie theater but with 2.1 speakers. The Night mode “compresses” the sound levels, making “quiets” a little louder and “louds” a little lower. This mode is good for late night listening with the sound turned down so that others aren’t disturbed by loud explosions and you can still hear the “quiet” portions. The final sound mode, Music, is for listening to music with the frequencies set at a more equal distribution.
There are also three buttons for Voice Adjustment. These adjust the voice frequencies to make voices easier to understand. At the highest level, number 3, we can tell that voices are much clearer but they sound somewhat unnatural. Consequently, we normally use level 1 and occasionally level 2 when necessary.
There are a series of lights on the front screen to indicate operation and when modes are selected. The main light comes on when the sound bar is in operation and goes off when it goes into sleep mode. This is a soft light and I do not notice it when watching the TV. The color changes whenever the Dolby 2.1 signal is received and being used. Other lights on the front will turn on momentarily whenever a new mode or source is selected to indicate that the signal has been received and the change made. There is also a light that comes on when Bluetooth is turned on. This goes off when Bluetooth is turned off or when Bluetooth goes into sleep mode if it is not in use for more than 15 minutes. Note, the auto sleep mode is not the default and this option has to be manually selected to be in use.
This sound bar produces much better sound than the TV speakers and requires little attention once the adjustments are set; we mostly use the TV remote. My only criticism regards adjusting the subwoofer levels. The subwoofer has bass minus and plus adjustment buttons on the remote but, unlike the other mode adjustments, there is no visual indication that anything is happening when this is used. There isn’t even an indicator that it is wirelessly linked except for the lights used when manually connecting it. The bass can be adjusted up to the point that deep voices and drums rattle items on the shelves in the room. When adjusted down to reduce such rattles we have no way of knowing if we are at a mid or lowest level. The bass can be adjusted to what is being listened to, but it would be nice to know the actual setting so that a “standardized” level could be selected for particular circumstances.
