Theater Solutions B83GR vs Alpine Corporation Solar Bluetooth Rock Speaker

The Alpine Corporation Solar Bluetooth Rock Speaker is a slightly better speaker than the Theater Solutions B83GR. Though they're both designed to look like rocks to blend with outdoor landscapes, the Alpine Corporation is slightly better built, has somewhat of a more balanced sound profile, and has a significantly longer battery life than the B83GR. That said, the B83GR has a larger Bluetooth range and can link to up to 99 additional speakers of the same model, which can be useful for those with a large outdoor space.
