Don't make the mistake of installing outdoor speakers without the corresponding outdoor volume controls. Sure, you can still adjust your outdoor speakers from inside, but do you want to have to run indoors every time you need the slightest change in volume? Volume Controls can be a great addition to an outdoor audio system and give you convenient hands-on control. Just like the freedom of indoor volume controls, outdoor volume controls let you enjoy the party and control volume levels as needed while maintaining a safe impedance level for your receiver or amplifier. These outdoor volume controls provide proper impedance matching and can take outdoor climates because they are constructed of sturdy, weather-resistant seal box. Install them just about anywhere, including mounted on a PVC pipe or on on-wall.
