Verdict

The LG SC9S is a 400W 3.1.3 channel soundbar system featuring the world’s first triple up-firing channels, including a dedicated up-firing center driver designed to enhance dialogue clarity and overhead spatial effects. It supports premium audio formats like Dolby Atmos, DTS:X, and IMAX Enhanced, and offers high-resolution audio up to 24-bit/96kHz. A major pro is its 'Synergy' design, which includes a dedicated bracket for seamless mounting with LG C2 and C3 OLED TVs, along with 'WOW Orchestra' technology that allows the soundbar to work in harmony with a TV's internal speakers. Performance highlights include a powerful 220W wireless subwoofer and advanced AI Room Calibration for optimized acoustics. However, potential cons include the lack of dedicated side-firing drivers for a wider surround stage and a limited LED interface that can be difficult to interpret without the companion app.
