Our Verdict
LG SP9YA
Bose Smart Soundbar 900 with Speakers + Bass Module
The Bose Smart Soundbar 900 with Speakers + Bass Module is better for mixed usage than the LG SP9YA. The Bose is better built with discrete satellites. It has better soundstage, center, surround, and Atmos performances. That said, the LG offers more sound enhancement features, such as EQ presets. Unlike the Bose, it supports DTS content and has a Full HDMI In port for high-quality passthrough.
