The Polk provides must-have options too, together with Wi-Fi and Chromecast streaming that go lacking from cheaper fashions just like the Vizio V21. The Signa lacks the DTS Digital:X processing of rivals Vizio and Yamaha, nevertheless. Digital:X helps create a convincing encompass discipline with out the usage of rear audio system, and it pushes these manufacturers forward for TV watching. 

The Vizio V21 is a better option for customers who desire a soundbar that does music and films in equal measure; the Polk is healthier for music lovers who crave thrilling, detailed sound and punchy bass.

The Polk Signa S3 is a soundbar/wi-fi subwoofer combo that builds on the success of different Polk fashions just like the Signa S1 and the Command Bar. On the floor it seems just like 2014’s Signa S1 — solely with a nicer, wool-like grill — however the internals have acquired quite a lot of essential upgrades.

How does it sound?

I examined the Polk Signa S3 towards two different 2020 soundbars — the Vizio V21 and the JBL Bar 2.1 Deep Bass — and it pulled forward of the opposite two in a single essential respect: it was essentially the most enjoyable with music. When judged by itself the Vizio sounds nice, however in direct comparisons to the Polk it got here throughout somewhat chesty and boxed-in. The Polk burrowed additional into recordings, releasing key particulars, making it simpler to overlook I used to be listening to a soundbar.

Whether or not I used to be watching a present streaming from Netflix or listening to some Spotify, the Polk Signa S3 was pure sounding with a good stereo soundstage, plus a forcefulness and feeling of energy when wanted. There was no sense that it was holding again or distorting, and it delivered spectacular scale for a comparatively compact speaker.

I began with Mitski’s heartbreaking Your Finest American Woman, and on the Polk her efficiency sounded each forceful and brutal — however the speaker was additionally in a position to floor tiny particulars such because the little “hmph” at first of the track. The S3’s tuning tends towards the thrilling finish of the spectrum, nevertheless, so the distorted center eight was hardest to take heed to among the many three ‘bars. As compared, the Vizio specifically sounded somewhat veiled and lacked the Polk’s dynamics. 

The Polk additionally belted out large productions like Kamasi Washington’s model of the Fists of Fury theme. The Vizio sounded laid again however closely separated. Turning off Digital:X on the Vizio diminished the carnival halfway impact somewhat, however I nonetheless wished to return and take heed to the track on the Polk.

Whereas Digital:X could be a distraction throughout music, it helps the Vizio with many film soundtracks. Through the Thanator chase scene from Avatar (at 26:53), the Polk managed to convey the dialogue however the swirling bugs and stomping creatures have been somewhat blunted by comparability. Adjusting the Polk’s bass management and sound mode did not assist deliver again the slam of the Vizio or the JBL.

Within the foyer scene from The Matrix, nevertheless, the tables have been turned. The Vizio struggled with the pulsing bass rating, however the Polk’s bigger, extra muscular sub was higher in a position to convey every of the notes.

Must you purchase it?

The Polk Signa S3 is a robust soundbar worth particularly if you will get it for lower than its $250 checklist worth. The Signa S3 gives a stable efficiency with music, due to the bigger sub and a number of latest tech together with HDMI ARC and Wi-Fi streaming. On the subject of films, it is not as punchy because the JBL Bar 2.1 or as evocative because the Vizio V21, nevertheless, so both of those could also be higher selections when you’re not going to take heed to a lot music in your soundbar.
