Polk Signa S2 Honest Review: Clear Voices, Honest Limits

I bought the Polk Audio Signa S2 in January 2026 for one reason: Gloria could not hear the evening news. We had replaced our old 50 inch Samsung with a 55 inch TCL 55T7 before Thanksgiving football in November 2025, and the picture was a clear step up. The sound was not. The TCL's built-in speakers made anchors sound like they were talking through a towel, and every commercial came through louder than the actual broadcast. Gloria is the one who complains when dialogue is hard to hear, and she was right. I am 58, a retired city bus mechanic in Raleigh, and I have never owned another soundbar. This is not a review from a home theater showroom. It is ten months in one living room, about 11 feet from the couch, with local news, college football, NFL Sundays, basketball in winter, and the occasional baseball game in summer.

Here is the honest version nobody tells you before you buy a bar like this. The Polk Audio Signa S2 is very good at the job I bought it for, which is making voices sound like voices. It is not a whole-room transformation, it is not a replacement for rear speakers, and it will not make a bad broadcast sound like a movie theater. If you want a bar that disappears under the TV, clears up dialogue, and adds enough low end to make a kickoff return feel like something, this is a sensible place to look. If you want to feel a stadium in your chest at low volume, keep reading the limits section before you click anything.

What Nobody Tells You Before You Buy It

The first thing nobody tells you is that a soundbar is a room decision as much as a product decision. Our living room is one room, not a dedicated theater. The TV hangs on the long wall across from the couch, about 11 feet away. The couch faces it straight on. There is a window on one side and a kitchen opening on the other. That layout matters more than a spec sheet because a bar that sounds spacious in a showroom can sound thin against a bare wall, and a bar that sounds boomy in a carpeted den can sound bright in a room with hard floors. I did not measure the room with any gear. I just paid attention to how often I reached for the remote.

The second thing nobody tells you is that most of the dialogue problem is not volume. It is separation. The TCL's built-in speakers put music, crowd noise, and voices in roughly the same place. When I turned up the news to hear an anchor, the commercials got louder too. The Polk Audio Signa S2 did not make the TV quieter. It made voices sit forward enough that I could leave the volume alone. That is a small distinction with a big effect on how the evening feels. Gloria stopped asking me to turn it up. I stopped bracing for the commercial break.

The third thing nobody tells you is that the bar itself is small. The listing says 35.43 inches wide, 2.15 inches tall, and 3.31 inches deep, and it weighs 3.9 pounds. On our low media console it looks like a strip of trim rather than a piece of furniture. That is good under a 55 inch TV because it does not block the bottom edge of the screen or the TV's remote sensor. The specs say it is designed not to block the TV's bottom edge or IR remote sensor, and in our setup that held true. I did not wall-mount it. It sits on the console, which is what the specs allow, and the wireless subwoofer sits on the floor at the left end of the console.

The fourth thing nobody tells you is that the remote matters more than you think. The Polk Audio Signa S2 comes with a remote, and VoiceAdjust is the control I actually use. It is not a feature I leave on some automatic setting. I raise it for local news when the field reporter is in a noisy location, and I leave it alone for football. If you hate having another remote on the coffee table, that is a real annoyance. I keep ours in the console drawer and pull it out when I need it. The bar also has built-in music streaming, but I have to be honest: I have not used it much. We listen to music through the TV or not at all. I am not going to pretend a feature I ignore is the reason to buy.

How I Tested It in One Ordinary Living Room

I did not run a lab test. I ran a routine. Every weekday morning I make coffee and turn on the local news. Gloria joins me for the evening news at 6. On Saturdays in the fall we watch college football, and on Sundays Marcus comes over for NFL games. In winter we watch NBA and college basketball. In summer a baseball game might be on in the background. That is the whole test cycle, repeated for about ten months. No second TV, no den, no patio setup. One living room, one couch, one bar.

The chain is simple. The TCL 55 inch T7 is on a Mounting Dream full motion mount on the long wall. The Polk Audio Signa S2 sits on the low media console beneath it. The wireless subwoofer is on the floor at the left end of the console. The bar connects with one HDMI cable to the TV's ARC port. The Roku Streaming Stick 4K is still what we use for streaming, and the indoor antenna is what we use for local broadcast. I control almost everything with the Roku voice remote, but I use the soundbar remote when I want VoiceAdjust. That is the entire setup. If your setup is more complicated than that, you are a different customer than I am.

The first week was mostly about volume. I kept reaching for the remote because I was used to the TV speakers and I did not trust the bar to hold a dialogue level. By the second week I noticed I was leaving the volume in one place for the evening news. That was the tell. The Polk Audio Signa S2 was doing the thing I bought it to do. It was not making the room louder. It was making the voices clearer at the same volume. Gloria noticed before I did. She stopped asking me to turn it up, which is a better review than anything I can write.

The Good: Dialogue Without the Volume Ride

The best thing about the Polk Audio Signa S2 is that it fixes the specific problem that made me buy it. Local news is a hard test because it is not mixed like a movie. An anchor at the desk sounds different from a reporter in a parking lot, and the commercial break is often louder than the broadcast. With the TV's built-in speakers I was constantly nudging the volume. With the bar I set a level and left it. The anchors sounded like they were in the room. The field reports still had background noise, because that is how field reports work, but I could follow the words without leaning forward.

VoiceAdjust is the feature that earns its place. It is not a magic button, and it will not turn a mumbling broadcast into a clean studio recording. What it does is let me push voices forward when I need to without turning the whole room up. I used it most during the evening news, when Gloria and I are both tired and neither of us wants to ride the volume button. I also used it during football halftime shows, when the panel is talking over crowd noise and music. For the actual game, I left it alone. The crowd sounded like a crowd, and the announcers stayed clear enough.

The wireless subwoofer is the other half of the story. It sits on the floor at the left end of the console and connects wirelessly, which meant I did not have to run a cable across the room. It adds weight to football and basketball without turning the news into a rumble. On a kickoff return you feel the hit and the crowd in a way the TV speakers never managed. On the evening news it stays out of the way. That balance is what I wanted. I did not want a bar that makes everything sound like a trailer. I wanted a bar that knows when to sit back.

The bar also handles everyday TV better than I expected. Sitcoms, cooking shows, and the local morning news all sound natural. The 5 full-range drivers do a better job with voices than the TV's built-in speakers, and the surround audio output spreads the sound enough that I am not always aware of where the bar is. I am not saying it creates a bubble of sound behind the couch. I am saying it fills the front of the room well enough that I stopped thinking about the speakers. For a living room 11 feet from the TV, that is the right result.

The Limits: What It Will Not Do

Here is the part that separates an honest review from a sales page. The Polk Audio Signa S2 is a soundbar and a wireless subwoofer. It is not a surround system with rear speakers. The specs list surround audio output, and the bar does spread sound wider than the TV alone, but it cannot put a crowd behind your head. If you want the ballpark where the announcer's voice comes from the center and the crowd comes from the sides and back, you need a different setup. I do not have rear speakers, and I do not miss them for news. For a big action movie, I notice the difference.

The second limit is volume. The bar is happy at normal living room levels. When I pushed it for a loud action scene, the subwoofer started to call attention to itself in a way that did not match the rest of the sound. It was not distortion, exactly. It was the low end getting thicker than the scene wanted. I turned it down and the balance came back. If your idea of a good time is a wall-shaking movie night, this is not the bar that does that best. If your idea of a good time is a clear football broadcast and a news show you can follow, it is.

The third limit is the room. Our living room is not a giant open floor plan. The couch is about 11 feet from the TV, and the room has walls and furniture that keep the sound from running away. In a much larger room, or a room with high ceilings and hard floors, I would expect the bar to work harder and sound thinner. I cannot test that because I do not have that room. What I can tell you is that in a normal living room, at a normal distance, the bar has enough output. Outside that, your mileage will vary.

The fourth limit is the little stuff. The remote is small, and I have misplaced it twice. The enclosure is plastic, and the warranty is limited, which is worth knowing if you are hard on gear. The built-in music streaming is there, but I have not made it part of my routine. None of these are deal breakers for me. They are the kind of details that separate a four star product from a five star product. I would rather tell you about them than pretend the bar is perfect.

Gloria stopped asking me to turn up the news. That was the whole job, and the Polk Audio Signa S2 did it without making the rest of the room louder.

Who This Is For

This bar is for people who watch the news and sports and want to understand what they are hearing. If you have a thin TV with built-in speakers that make anchors sound muffled, the Polk Audio Signa S2 is a practical fix. It is for a living room, not a theater. It is for someone who wants one bar, one subwoofer, and one cable, and who does not want to build a system with rear speakers and a receiver. It is for the person who notices that commercials are louder than the show and wants to stop riding the volume button.

It is also for couples with different hearing. Gloria is the one who complains when dialogue is hard to hear, and I am the one who hates turning the volume up and down. The bar met us in the middle. If you have a partner who asks what did he say during the evening news, this is a reasonable thing to try. It will not fix a hearing aid, and it will not fix a bad broadcast. It will make the voices clearer at a normal volume, which is most of the battle.

Who Should Skip It

Skip it if you want a true surround system. The Polk Audio Signa S2 is a bar and a subwoofer, not a room full of speakers. If you want crowd noise behind you and a ballpark announcement from the sides, you need rear speakers or a different setup. Skip it if you have a very large room with high ceilings and hard floors. The bar can only do so much, and a bigger room will ask more of it. Skip it if your main goal is deep, room-shaking bass for action movies. The subwoofer adds weight, but it is not a dedicated home theater sub.

Skip it if you hate extra remotes. The bar comes with one, and I use it for VoiceAdjust, but if a second remote on the coffee table is a deal breaker for you, factor that in. Skip it if you want a piece of furniture. It is a slim plastic bar, and it looks like a slim plastic bar. That is fine under a TV, but it is not a design statement. And skip it if you need a guarantee that every broadcast will sound perfect. No soundbar can promise that. The Polk Audio Signa S2 made our news and football better. It did not make bad audio good.
