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.

A Hi Josephine, We offer free ground shipping to anywhere in the US. Free shipping does not apply outside the US. I believe Amazon Canada carries this model and should be able to give you a better rate. Hope that helps! Thanks. -BM 2359
Steve • 12/17/2019, 2:17:43 PM Q why doesn't your website allow for a choice in color? I am looking for canyon brown color.
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Steve, These are only available in grey right now.
Billy Wresch • 12/17/2019, 2:17:43 PM Q Can I use these with an OSD-AMP60, will that do the job?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Billy, Yes the AMP60 would be a good amp to power one pair of the RX550's. If you're looking to do more than one pair, I suggest going to the AMP120. CS 3065

This transmitter is also made like a rock but it doesnt have to be if replaced. I just dont know what to buy to replace it. model number, etc...
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Andrae, Are you possibly mistaking these speakers for the WR-150 wireless rock speakers? These RX550 are not wireless and do not utilize any kind of transmitter. We do sell the WR-150 transmitter on our site or you can email our return department at
