Polk Audio Signa S3 Review

The Signa S3 from Polk Audio is a 2.1 soundbar system that costs only $249 and aims to bring theatre-like rumble into your home.

Unexpectedly, the Signa S3 produces much power; there is a lot of bass depth, balanced mids and clean, crisp highs. Although the system has minor drawbacks, having multiple listening modes increases versatility. The system is also a good deal.

Ultimately, both products have a superb sound quality and are worth the money. The final decision between these two models is what features are most important to you.

Polk speakers, are they good quality?

They sound better than average for the price, but the strong bass can give the impression otherwise. A reputable and well-known audio gear manufacturer, Polk Audio is well-known for its broad selection of speakers that come at every price point.


If you want a soundbar and don’t want to spend much money, we recommend the Polk Audio Signa S2. A good soundbar option is the Polk Audio Signa S3, but only if you require WiFi and intend to buy an 8K TV soon. The Polk Audio Signa S2 is the better option if you don’t require WiFi connectivity and don’t have any immediate plans to upgrade to an 8K TV.
