    Do I need special cable to run outdoor speakers?
    We strongly recommend our direct burial, CL3/FT4 waterproof cable and wire connectors that are designed for the outdoors. Our speaker wire uses a specially formulated UV-resistant, white polyethylene jacket that provides protection against water damage and allows the cables to withstand extreme weather conditions like rain, snow and high temperatures and incorporate twice the insulation of average cable. If you plan to bury the cable, OSD recommends you bury it 4-6" underground so that it's not visible nor pose a danger of somebody tripping over it. Our speaker cable is ideal to use in direct burial applications. As for the gauge, for runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, we suggest 14-gauge wire. 

    Add Volume Controls
    Volume controls can be a great addition to a system providing both proper impedance matching and more hands-on local control of the volume in the listening area. We offer a great selection of outdoor volume controls to choose from!

    Extremely Durable
    OSD outdoor speakers are developed with harsh conditions of the outdoors in mind. Our rock speakers use only non-water-absorbing materials and won't absorb any water. This is critical in winter so it won't freeze and crack. The shape is designed to withstand large amounts of pressure, extreme temperatures and moisture. Remember though, outdoor speakers are an investment, so take care of them. Storing them away from extreme weather conditions will only lengthen the time you will get enjoying outdoor speakers. These rock speakers utilize weather-resistant components for years of trouble free performance.

    Devin • 12/17/2019, 2:17:43 PM I was wondering if there was speaker wire attached to the product and if so how long???
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Devin: There is a three foot lead coming out of the bottom of the speaker. We also offer CL3 Rated Direct Burial Cable in 16/2 (16 Gauge two conductor) for runs up to 80 feet and 14/2 (14 Gauge two conductor) for longer runs. We also recommend our Aqua Blue Direct Burial connectors for terminating the speaker cables to the three foot leads. TL
    Bob • 12/17/2019, 2:17:43 PM I am planning on using these speakers by my pool where they will have exposure to direct sun and rain. I will be using them during the months May - September. How will they hold up to the elements?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Bob: All of our rocks are built to withstand the elements. It is recommended to put them away during the months you will not be using them. TL
