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. |

Highly recommended.
This is definitely a big improvement in sound (volume, clarity and bass) over what were already pretty nice sounding built in television speakers which I listen to at about volume level 9 (of 100) for casual daily YouTube videos. I can bring it to level 13 when wanting to be more immersed in Netflix and such. I don’t need much volume in my home (though in my car I have a 12” subwoofer and play music at 75% volume LOL).
VOLUME: The sound bar can get much louder and with that extra volume it stays more clear without being distorted unlike the built-in television speakers that start to sound distorted when it gets 50% and above in volume.
REMOTE CONTROL: This soundbar CAN be controlled with my TVs remote so long as it’s connected not just with the optical audio cable but the HDMI cable as well going into an ARC HDMI port on the tv. The soundbar turns on when I turn on my tv and turns off when I turn off my tv.
I don’t see a volume level on the soundbar which is my first complaint about the soundbar. It’s also not on my tv when using the soundbar. I just see a + or - on the tv when I press those buttons.
EQ (ISSUE 1): Sadly there is no real EQ settings on this. There are several buttons on the REMOTE ONLY (not on the soundbar itself) that have 6 custom sound settings: Movie, Night, TV, voice 1, voice 2 and voice 3. I’m not sure if you can combine these. I switched to “night” and then “voice 3” thinking that maybe it would simply enhance the voice on night mode but when I press night mode again it resets the voice setting. So I think it’s either or. And as a 7th choice you have your bass volume. Thats the extent of EQ options.
When using the built in speakers the TV had tons and tons of options with 5 frequency sliders (for sub bass, bass, mids, high mids and treble), surround sound, magic sound, add bass, add treble… so much. That’s all greyed out when using the optical audio out to this soundbar. I don’t know if all of those settings would still be there if I got an LG sound bar with my LG television. But considering I don’t know what brand of television will be my next, I couldn’t worry myself with matching the soundbar brand.
So far, I guess it doesn’t matter that there aren’t as many EQ settings, the speaker sounds pretty good as is. I leave it on “Movie” for everything. I have my Apple Music hooked up on the television but haven’t used it for music yet, I presume I would want to put the soundbar on the music setting for that.
ISSUE 2: I am not sure is an issue with the speaker or the television but when watching YouTube for example, if you are on the YouTube menu, there is no audio signal being sent to the speaker and thus you see single white dot of light. When you have clicked on a video and the audio signal is sent to the sound bar, the single white light turns green. The PROBLEM is that there is a fraction of a delay after the video has started before the sound starts on the speaker. There are many videos I watched that for some reason has someone speaking from the very first frame of video and the sound bar always misses it, the sound turning on 1-2 words late into the video. It has nothing to do with speaking specifically, whatever the sound is in the video, the speaker doesn’t activate until a fraction of a second after the video starts. It’s a bit jarring, and a little more annoying. If I rewind the video to the beginning I’m just repeating the situation because rewinding means there is no audio signal going to the speaker and so I see the white dot again, that once again doesn’t turn green until a fraction of a second after the video starts again.
But aside from those issues, it really does sound good and I haven’t felt a need to crank up the base much because it sounds pretty full as is, without sounding too bassy or muffled. I experimented with the voice enhancement buttons. I’ve settled on “voice 2” to bring just a little bit more clarity and audibility to the voices when I have the volume a bit lower so as not to disturb others.
It sounds good, I can make it louder than ever before if I want. I can control its volume and on/off without needing its remote (though I need its remote for the other EQ settings). I got it “open box” but it looked brand new I must say for $143.80 which is a good price for what this is. And I trust the Polk brand.
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.
