True Dolby Atmos Surround Sound

Signa S4 is Dolby Atmos Certified* to immerse you in 360 degrees of surround sound. From added ambience in music to special effects flying overhead, Signa S4 provides an incredibly realistic sound environment. Plus, standard audio played through the Signa S4 can be up-mixed to create a virtualized Atmos experience.
* Requires HDMI eARC connection between sound bar and TV

Advanced 3.1.2 Sound Bar

The Signa S4 sound bar’s advanced seven speaker array was designed to deliver a lifelike Dolby Atmos 3.1.2 listening experience. Its dedicated center channel provides crystal clear dialogue and its optimized left and right tweeters and woofers deliver a huge, wide sound stage. Plus, dual, up-firing speakers take advantage of Atmos’ height channels to send sounds over your head, rounding out your 3D sound immersion.

Polk VoiceAdjust™ – Hear Every Word

Tired 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

Optimized Sound Modes

One-button, preset sound modes optimize the Signa S4 so you can have the best sonic experience for movie watching and music listening. And don’t worry about waking your family or neighbors during late night, binge watching sessions. With Night Mode, one button lowers the bass while increasing VoiceAdjust so you can hear every word, without raising the master volume.

Sets Up In Seconds

Set 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.

50 Years of Engineering The Perfect Home Theater Sound

Signa 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 never imagine.

I really wanted to like this pillow but I didn't, My son did.
Color: Blue, Size: Medium
I bought two of these Medium pillows for summer camp that my son and I went to this year. Let me start by saying the only reason I don't like it is because its too soft and small for me. By soft I mean the pillow bottoms out when I put my head on it. I measured and it is 4" thick but when I put my head on it, it almost disappears. They could add 20-25% more stuffing and it would be great. My son liked his, I didn't even bring mine. What I did do is stuff a standard size memory foam pillow in the stuff sack and used that! The quality of this pillow is great, the seams were not torn or coming undone like some people said, no rips or stains. the zippier works just fine and IT IS MEMORY FOAM, people who complain that it's not are expecting a brick of foam which this isn't, it is shredded/torn memory foam filling that is exactly like my $60 memory foam pillows that I use on my bed. TLDR its great for kids, not for people with bowling balls for heads like me. WISE OWL, ADD MORE FILLING ! I was able to stuff a pillow 3x the size of this one in the same bag.

Comfy!
Color: Black, Size: Medium
It's very comfortable. It's a good size and thickness. I wish it had a strap to hold it on to your air mattress or cot. Good value!

I purchased the toddler size as a back support pillow. Quality! Firmness!
Size: Kids 13"x18", Number of Items: 1
I LOVE this pillow! OK, I admit that I just got it and opened it, but I already know I'm going to love it. I purchased the toddler-sized pillow to use behind my back in the car or on an airplane - or maybe just a snuggle pillow in the bed - a tiny version of a body pillow. I got exactly what I wanted! This pillow is exquisitely crafted, and I can feel the cooling quality already. I purchased a brand new silk zippered pillow case for it. I inserted the pillow in the case right away because I know it's going to expand over the next 72 hours - to the perfect firmness, I hope. I'm afraid if I wait until tomorrow it might not be able to fit into the pillowcase! Some people here have reported a distaste for the firmness of this pillow, but I'm looking forward to it. So, I recommend if you want to really firm pillow, you had better put it right in the pillowcase when you get it, because you might not be able to stuff it in if you wait 72 hours! By the way, this pillowcase has absolutely zero smell, so don't bother your sleepy head about that.

Great pillow for side sleepers!
Size: Standard 20"x28", Number of Items: 2
I bought these pillows at first because I wanted to try out the “coolness” of them (I live in a place with no AC). They’re definitely not cold, but they do a good job of regulating the heat on particularly hot/stuffy nights. But my favorite thing about these by far is the support! I’m a side sleeper, and these are just the right amount of firm to tuck between your shoulder and neck that keeps your neck in a good position all night, while still soft and comfy for your head! I’ve been sleeping on them for about 2 months now and they have maintained their shape really well. Definitely recommend!
