Weatherproof rock speakers are not a new concept. While these are a good way of discretely getting music into your backyard, the thing with the typical rock speaker is that the actual speaker is of an unfamiliar brand which makes me question the overall sound quality. With a name like Klipsch though, my perception is a little bit different.
These weatherproof speakers have dual tweeters so that you can play both left and right channels from a single rock. This means less wiring to worry about hiding. Just in time for summer for around $299.
