Our Verdict

Klipsch Flexus Core 300

LG Sound Suite H7

The LG Sound Suite H7 and Klipsch Flexus Core 300 are both all-in-one soundbars with integrated subwoofers. You can expand both systems with each brand's respective speakers and subwoofer, but the LG allows you to go up to four satellites compared to the Klipsch's two. Still, the Klipsch is the better option standalone, since it has HDMI In and Optical support and works with DTS family audio formats, while the LG doesn't.
