We added an audio system to our pool area.
Visible there are 3 of 6 speakers, and the sub-woofer that will get buried in the ground except for the mushroom cap. It is driven by this system in our pool mechanical room.
It integrates with our whole house audio system such that we stream music to it from our libraries or through a streaming service, like Spotify.
What a difference it makes. We can now play music at a reasonable level and hear it clearly in the pool, without blasting out the neighbors.
