Origin Acoustics is one brand that has come up with some creative designs- the founder also founded Speakercraft, a well-known brand that has slipped a bit since he left.
Other brands make similarly-styled subs and satellites- for the sake of any neighbors whose house is close enough to the pool to hear your music, it would be best to focus the sound away from their house and toward yours- not only does the sound not travel toward them well, it will reflect off of your house/garage and require less power/volume than firing outward and away, never to be heard once it leaves the area where you want music.
Origin Acoustics' is the premiere manufacturer of outdoor audio loudspeakers. From our discreet landscape outdoor series to our Outdoor Bollard Loudspeaker, we have simple stunning installed audio for your outdoor oasis.
