Our Verdict

LG SL10YG

LG SP9YA

The LG SP9YA is better than the LG SL10YG. The SP9YA has a better soundstage and more sound enhancement features, including room correction. Unlike the SL10YG, it supports Apple AirPlay connectivity. Some listeners may also prefer its more neutral, balanced sound profile out-of-the-box. That said, the SL10YG offers a better surrounds performance.
