Features & Specifications

The RS790 is a single rock speaker and a great fit for spacious backyards and pools. This stealthy model includes 200 Watts of power and has an 8-inch woofer for exceptional coverage and bass response. These are important features if your outdoor music has to compete with ambient noise like splashing from the pool or traffic noise. Customers typically purchase two or more to cover areas as large as 1000 square feet.

· Aerospace-grade weather-resistant material ensures protection from water, salt, pool chemicals, etc.

· Incredibly realistic looking with high power handling capability

· Fill large backyards with rich clear sound with no distortion

Weather-Resistant Enclosures
Customers often ask us if our outdoor rock speakers can handle the elements. OSD Audio rock speakers are engineered specifically for even harsh weather with durable aerospace-grade, multi-layer composite cabinetry that can take heat, cold, wind and rain.

Rock Speaker Installation Tips
Installing rock speakers is easy and can be a lot of fun. First, decide where you want your new rock speakers to go. Most of our customers like to hide them in landscape border areas or garden beds. You'll need to run outdoor speaker wire from the speakers (all our rocks include a 3-foot speaker lead) to a sound source. Most outdoor speakers are passive devices, which means they do not have built-in amplification and will need a source of power. You can connect your outdoor speakers directly to household amplification like a home receiver or outboard amp/receiver stored safely in a tool shed or other covered space where it is protected from the elements. The OSD team recommends you bury wire 4-6” underground so that it's not visible nor pose a danger of somebody tripping over it.

What kind of cable do I need?
Direct-burial cable is strongly recommended. We offer CL-rated cable that can withstand extreme weather conditions and uses twice the insulation of regular cables.

To improve longevity of the surface quality on our outdoor speakers, place the rocks in a shaded area to prevent color fade from too much direct sunlight. It is recommended to keep our outdoor speakers out of contact with any chemicals that may be present in your yard. We encourage you to bring the speakers indoors or cover them up during the off seasons to ensure a longer life for the speaker

Brad Hunter
from Lufkin, Texas asked:
July 16, 2012 With the receiver shown above, will I need an additional amplifier for an outdoor setup of 6 speakers. I plan on using(4) RS790 and (1) Omni Speaker and (1) patio speaker. The receiver is 100W X 6 @ 8ohms. I would like to have 4 volume controls as well.
1 Answer
Hi Brad: Yes we would suggest you add an external amplifier like our OSD-AMP200 High Current Amplifier to the Multisource Audio (R&L) Output. Plus in addition to your RS790 speakers (I am assuming 4 each or 2 pair) we would add a DSM4 Dual Source Speaker Selector to organize the four zone output. One pair of the RS790 connected with an OSD-OVC300 Outdoor Impedance matching Volume Control for zone #1. The second pair of RS790 connected to another OSD-OVC300 IM VC for Zone #2. For Zone 3 would recommend our OSD PS-525 single Stereo Planter Speaker featuring 360 degree dispersion (same as the Omni speaker). This would be connected to a third OSD-OVC300 using a four conductor speaker wire from the AMP to the DSM to the Volume Control then to the Dual Voice Coil Speaker featuring left and right input. Last but not least would be Zone 4 which the AP550TT would be the optimum choice. It also features a DVC, Dual Tweeter set up connecting a stereo right and left four conductor connection. Just like the PS-525 Stereo speaker both of these take a stereo input (left & Right +/-) and create what we call a Summed Mono Stereo output. . This gives you your four Volume Controls, a speaker selector with independent on/off switch for each zone and Powerful 2 Channel Amplifier featuring automatic Source Switching. We would suggest setting the Impedance settings for each Volume Control to 4X. We also feature CL3 Rated speaker wire in both 2 and 4 conductor configuration in both 16 and 14 gauge offerings. Check out our Aqua Blue connectors to terminate your RS0790 as well as the PS525. Our OSD CL3 rated speaker Cable is also approved for Direct Burial applications as are the Aqua Blue connectors. Please let me know if we can answer any other questions. Thank you for considering OSD Branded Products. TL

I see the RS790 is sold out and if I'm reading this right has been discontinued. What other comparable speaker is available? Will a new mode be forth coming to replace the RS790?
1 Answer
Hi Gene, Our RS810 and RS850 are great sounding 8" rocks with tons of power. Just make sure to run a nice, powerful amp to them!

from Charlotte, NC asked:
May 21, 2014
I have recently purchased two of these RS790, and was going to power them with one AMP120. Will these perform well if I bridge the two assuming they will drop to 4ohms? Any issues or concerns with this approach?
1 Answer
Hi Brian, The AMP120 will be pushing 150 watts out in bridged mode and the RS790 speakers can handle up to 200 watts each so that should be safe. Of course it will be mono sound when bridged, but you will get more power. Let us know if you have any further questions. Thanks! BM 2701

from CA asked:
April 28, 2014
is the price of the pair? or one unit?
1 Answer
Hi Henry, The price you see is for a single speaker. These are set to be discontinued when they sell out, so they're at an all-time-low price right now. It's a great speaker, but we have so many models that we had to cut down a bit. Let us know if you have any further questions. Thanks! BM 2649
