New transducer technology allows you to mount these on the back side of a surface without cutting any holes! The sound is emitted through the surface and the transducers remain completely hidden. These are great for spa and hot tub applications as well as boats, saunas, bathrooms, and float tanks. Completely waterproof.

Transducer technology allows units to be completely hidden behind the mounting surface
Perfect speakers for inside of my small sauna. When testing, keep in mind these transducers basically turn your wall into a speaker. They may not give off much sound until properly mounted to a large flat surface but were more than adequate in my application and incredibly easy to install.
