Klipsch Cinema 400
Score: 73/100Rankings
Klipsch Cinema 400 is a 2.1-channel soundbar that offers a robust 8-inch wireless subwoofer delivering strong bass and Tractrix horn-loaded tweeters for clear highs. The absence of Dolby Atmos and limited smart features make it less future-proof. Great for TV upgrades in apartments where space is limited but powerful bass is wanted.
The Polk Audio Signa S2 is a low-profile 2.1 soundbar with a wireless 5.25-inch subwoofer delivering solid bass and VoiceAdjust dialogue enhancement. Its plastic construction and limited channel configuration restrict its appeal for larger home-theater setups. Best for budget-conscious owners of 40-55-inch TVs seeking easy installation and clear dialogue.
