Our Verdict

LG S75QR

LG SP7R

The LG S75QR is better than the LG SP7R. The main difference between the two bars comes from Dolby Atmos support. While the SP7R doesn't support Atmos, the S75QR does. Additionally, the S75QR can correctly implement surround sound formats like Dolby Digital and DTS for a more immersive feel.
