Polk Audio Signa S2 Ultra-Slim TV Sound Bar, $149 (Orig. $229)

Currently on sale for $80 off on Amazon — at 35% off its original retail price — this best-selling soundbar packs a serious punch without the bulk.
Before getting into just why this soundbar is the perfect slim powerhouse, here’s a brief rundown on how soundbars work.
Soundbars provide a richer, more robust sound output from your TV and usually come in a variety of “channels,” indicated in decimal format. The Signa S2 is a 2.1-channel soundbar. This means it features left, center and right channels for crisp clarity and depth of sound, plus a subwoofer for bass.
What’s arguably most impressive about this particular soundbar is that it works with any TV regardless of its size, brand or type. So pair it with your 4K or HD TV, sit back, and listen to it instantly boost the sound quality with the press of a button.
One of the Signa S2’s standout features that shoppers love is its Voice Adjust technology. This feature ensures that the dialogue your TV produces is clear and consistent at all volumes. So you’ll never have to strain to understand what’s being said in your favorite shows and movies again.
The included subwoofer also delivers just enough room-shaking bass, and it’s not too distracting or invasive.
With over 11,000 five-star reviews, it’s no wonder the Polk Audio Signa S2 is one of the best-selling soundbars in recent memory. One five-star reviewer gave a thorough review of the device, highlighting that it delivers “good sound, clear dialogue” and “turns on/off automatically.”
All in all, this is the best slim soundbar you’ll find anywhere.
