Our Verdict

LG SL6Y

Yamaha YAS-408

The Yamaha YAS-408 is a better soundbar than the LG SL6Y. Despite only being a 2.1 soundbar, the Yamaha's center channel performance is almost the same as the LG's, even with a dedicated center channel. Other than that, the Yamaha has more inputs, Wi-Fi and Apple AirPlay support, and better bass response. On the other hand, the LG has more sound enhancement features.
