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

Free ground shipping for limited time High performance without breaking the bank. Guaranteed to sound better than most rock speakers in the market or your money back. The HF9 rock speaker fits beautifully in larger backyards and pool areas or big commercial projects, as well as, other settings requiring more bass.

5 Questions & 5 Answers
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

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:

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

Shocking Results
I purchased these speakers to use in my back yard near the pool and spa. I was quite surprised as to how quickly they came. Although I did pay slightly more than I wanted, I kept in mind that one gets what they pay for. This is a great bang for the buck. These speakers do what they say they will and a bit more. I'm quite Happy with them all the way around

Great Speaker
The speaker sounds and looks great! It arrived right on time and in perfect condition. The only problem I had was that I thought I was getting two speakers. I was a little disappointed when I opened the box, only to find one. This is 100% my own fault though, for misreading the details when ordering the speaker. At the moment I have this speaker hooked up and two bose FreeSpace speakers and that is more then enough sound around my pool. I will be ordering another one of these speakers anyway though, just for good measure.

Great Product
I bought these speakers on the recommendation of a friend who has owned the same product for 7 years. Their speakers have worked flawlessly and have survived the weather without special protection. We use these around our pool and get lots of compliments.

The website showed the speakers in sets of two. Imagine my surprise when on Christmas morning my daughter and son-in-law opened their gift any only recieved 1 speaker. Seriously, for the price I paid for 1 speaker I could have purchased 2 speakers locally. Leason learned.... read the fine print.

Outdoor rock speakers ...
Outdoor rock speakers sound unbelieveable!! Im pretty picky and was a little hesitant since I wasnt buying a name brand, but am very glad I found their website. I have a pair of older outdoor bose speakers mounted above my covered patio and these new rock speakers on my uncovered patio and these totally out rock those bose. Im actually thinking about replacing the bose with something from these guys. These are very deep sounding with excellent bass and high trebles--when they said they dont need an extra subwoofer theyre not kidding! (I have the HF9 Advance Tech Rock Speakers). Go with these guys and you wont be dissappointed!! Highly recommend!!

These speakers sound fantastic! We installed a 70 volt system with 11 of the HF9's around our resort pool and created a great surround sound effect. Everyone keeps looking for the speakers in the planter beds. The best thing is the multitap power settings which allows us to set the volume of each speaker for even coverage around the facility. Oh yes, the price was great too.
