Review on 🏞️ Theater Solutions 2R6G Outdoor Granite 6.5" Rock 2 Speaker Set: Enhance Your Deck, Pool, Spa, Yard, or Garden with Granite Grey Acoustics by Brandon Harding

I connected them to an old Sony STR-DH100 receiver. For the price, they sound phenomenal. You can hear and even feel the bass. I was surprised as they are not that big. I don't hear any distortion even at high volume. You can see all the watertight seals inside the case. It should be noted that the first pair I received had an issue (one of the speakers sounded noticeably weaker than the other). I received a replacement pair quickly and haven't had any issues with them so far. I suggest you test them first before installing them.
