Our Verdict
JBL Xtreme 2
Alpine Corporation Solar Bluetooth Rock Speaker
The JBL Xtreme 2 is a better overall speaker than the Alpine Corporation Solar Bluetooth Rock Speaker. The JBL can produce a more extended low-bass than the Alpine, has a better-balanced sound profile overall, and can get louder. It can also play stereo content without downmixing it to mono, resulting in a more immersive soundstage. That said, some users may prefer the Alpine Corporation's rock-like design for their outdoor decor. It also has longer-lasting battery life, though this can depend on your usage.
