Features & Specifications

If you want the best omni speaker on the market, the OS850 is the one! We designed this outdoor ground speaker with fiberglass, not ABS plastic, for even better sound quality. This sturdy omni ground speaker is tough and includes a weatherproof 8" down-firing polypypropylene woofer that cannot collect condensation or dust. A new molded tweeter and woofer combo delivers smooth indoor quality sound and broader dynamic range for outdoor use, while the large weather-resistant port adds efficiency and additional 6dB of bass output. Installation is easy. Add one or even two for full, 360 degrees of beautiful sound in your backyard.

What Is an Omni Speaker?
Popular with landscape professionals and audio contractors, omni speakers offer omni-directional, 360° surround sound with no obstructions. If there are multiple people scattered in different areas, the sound is consistent, not mixed. This feature plus the durable nature of the Omni make it a popular speaker for theme parks, hotels, and resorts; however, omnis are also quite common for residential use.

Should I bury my omni speaker to get better sound?
You don't have to bury your Omni speakers but it will enhance sound quality and here's why. The sound comes out of the "mushroom cap" on top of the speaker. When you bury the omni (a few inches above the grille), the sound has a surface to bounce off of--the ground acts like a tuned baffle!

What kind of amplification do I need?
The OS850 is a passive speaker, meaning it will require power from an amplifier or receiver. This speaker has high power handling so you'll want to pair it with an amp that can handle 300W. We suggest our AP200 high current amp to get the best sound performance from your new omni speaker.

Please call for 70v Version


Other Product Info

If you want the best omni speaker in the market, this high definition garden omni 360 degree in ground speaker, designed for theme parks, hotels, or any architecturally landscaped area, simplify installation and deliver deep, rich and clear sound. This omni speaker is a 8” woofer cone with rubber surround, 1.5” mylar dome tweeter with 2 step crossover design for audiophile application.
This garden speakers are designed to blend into any environment which can be used for in-landscape burial. The enclosure is not made by ABS plastics like other omni speakers in the market. We all know ABS can have resonance that can't produce tight bass. We actually design this speaker using the same materials making our rock speakers (reinforced raisin fiber class). The result is a deep clean and tight bass that no other omni speaker in the market can produce. This advance USA engineering design ensures performance in even the most temperamental and unpredictable climates.

Thinking of using a Crown PS-400 to drive these. Your opinion? Also how do these compare to Stereo Stone 250W Commercial grade stealth rock speakers?
1 Answers
HI Dux: I believe the OS-850 speaker is a true omni speaker with a unique 360 degree design. It has a built in 70V Transformer for 70V or can be connected 8 ohm. You could easily power two pair with the CROWN amp for a 4 ohm stereo load. Or run all four in mono 70V. Excellent choice. And I believe could be half the price of the Stereostone. Good luck TL/4709

How does this speaker compare to the Bose Free Space 51?
1 Answers
Hi Dave: Bose is an amazing marketing company. The Free Space 51 is an amazing speaker. But try finding a Frequency Response for a speaker featuring a 4.5" full range driver. It would be lucky to produce below 120 Hz, and no Tweeter probably means a cut off at 16 kHz. The speaker is rated at 50W continuous with peaks of 100 watts as well so lets look at the OS 850. The OS 850 features an 8 inch 2 way coaxial design with a Frequency Range of 38 Hz to 20 kHz. So it actually plays a full range signal with some pretty good bottom end. It also has a sensitivity rating of 90 dB, of course BOSE does not list this spec either. 90 dB means the speaker is very efficient and does not need much power to drive it to full output. Did I mention this speaker is rated at 300 watts as well. The enclosure itself is 4 inches taller and an inch wider diameter. Plus this speaker is commercial grade and features an optional internal 70 Volt Transformer with five settings. We sell as many of the speakers for commercial as residential. Great bang for the buck. As far as the comparison, there is no comparison. The OS 850 should be selling for much more making it an even greater value. TL/4414

I am going to use this product, probably 4 for my patio/pool. I want to drive them with Sonos Connect AMP. With Sonos saying their device will do 55 W per channel at 8 Ohms. Will that work for these speakers, if not do you have a similar speaker that would work? Thanks.
1 Answers
Hi Evan: The SONOS Connect Amplifier has a right and left output and is rated at 55 W at 8 ohm. It does not give a 4 ohm spec so they do not recommend connecting 2 pair of speakers which would create a 4 ohm load. It is not the speakers you have to worry about. I would suggest going with SONOS Connect and purchasing our XMP100 amplifier which has both an A and B output and will run at a 4 ohm load. But don't take my word for it contact SONOS and ask them about connecting any two pair of speakers. Note the OS850 are rated at 90 dB sensitivity which means they are very efficient and do not need alot of power. The higher the sensitivity the more efficient. 3dB is doubling the power; so 87dB would need double the power. TL/4570

Hi, I'm in the process of moving to a new house and looking to get some Omni speakers. I currently have 4 OS800 speakers in my yard which has a pool centrally located. I'm looking to get a set of OS850 speakers. The yard is about 50ft deep from the house and about 115ft wide. Would 3 of these speakers be enough or should I get 4? And what's the best location? I've included a few pictures of the planned yard. Thanks for your help. Le

I have 2 RS690 rock speakers on one side of a patio. I would like to put 1 OS 850 in the garden in the middle and 2 RS690 rock speakers on the other end of the patio. The patio is 20' x 54'. These speakers run through a splitter into a receiver. each pair has volume control.
1 Answers
Hi Charlie: Based upon what you are telling me you have a Speaker Selector (your term splitter) and volume controls for each pair of speakers so far 2 pair RS 690. You want to add a single OS 850 Omni speaker which presents a problem since it has only one input. I am assuming you have another stereo output (R&L +/-) to run to the garden in the center of your patio. You really need a stereo Dual Voice Coil speaker that has aright and left stereo input but only a single DVC woofer and two tweeters (one for right and the second for left). Something like our RS 690TT Dual Voice Coil Rock Speaker. You can connect a Volume Control to this speaker as well whether it is a stand alone Volume Control or one built into the Speaker Selector. The DVC was made for this type of application where you want to connect a stereo signal but only space for a single speaker. You will notice the tweeters are 180 degrees apart. TL/4240

Hello - exactly how deep should these be buried? The manual doesn't actually say, it just tells you how large a hole to dig. Do you bury the entire bottom part? Higher? Thanks in advance.
1 Answers
Hi Mike: The idea is to bury the speaker up to the opening where the sound comes out so you use the ground as a natural baffle creating a loading effect. You certainly can experiment to see if it creates any difference for you application, so dig a hole deep enough to so the opening is ground level. If your satisfied with the effect then leave it. If your curious you can try filling in so the opening is a couple of inches above ground level and see if you hear a difference. It may also make a difference with what you have planted around the speaker. Good Luck TL/3867

are these a suitable replacement to a weathercraft ws 710 speaker?

The current speakers are two wire speakers
1 Answers
HI Rich: Not sure the OS-850 is a good match to your WS-710 speaker. The OS-850 is an 8.0" 2 way speaker versus the 5.25" 2 way of the WS-710. It does have the two wire connection as well (+/-). A closer match might be the RS660M Omni Rock Speaker which is a 6.5" 2 way with the same efficiency 90dB. It is available as each as well and comes in four different color choices. TS-2195

I bought 4 speakers OS850 however they do not sound clear. I am using a receiver Onkyo TX - NR616. I also bought an Amplifier MX1260 but I did not install yet. My question will be how to install the amp using the receiver? Plus I am worried that just using the receiver the speaker is not sounding right... imagine with the amp... Any help before I think that these speaker do not perform right?
1 Answers
Hi Claudio, We need to know what other components you were planning to use with the MX1260 multi-channel amp. Assuming it would be used for more than the four OS-850 omni speakers, we suggest connecting the MX1260 to the Zone 2 Pre-amp output of the Onkyo NR616 to the Buss 1 input. You could connect all four of the OS-850 to channels 1, 2, 3 and 4 of the MX1260. Set the switch for Zone 1 and 2 to ST or Stereo. Then make sure the input switch is set to Buss #1 for all four speakers. Then connect the first speaker to the left output of channel 1 and the second speaker to the right channel. Repeat for the third and fourth speaker from Zone 2 (channel 3 & 4). Make sure to adjust the gain control for each speaker to about half way. Now you will be able to hear all four speakers and see if the sound quality is isolated to one or all of the speakers. TL/MA 1459

Hi Bill: Yes the OS850 can be used to replace the LS3 (I am assuming these are the speaker you were referring to). I am curious about your system. What are you using for the source, are you using either volume controls or a speaker selector. Are you using a Receiver or amplifier (would like to know including make an model of all your components). Are the LS3 still under warranty, maybe we can figure what went wrong with the LS3's. TL

Hi Bill: I am assuming you are referring to the LS3 speakers. Can you tell us how you have your system wired. It sounds like you are running everything in mono. It would help to know what sources you are using as well. Are you utilizing any Volume Controls or Speaker Selector? Bottom line the OS-850 speakers can replace the LS3 speakers and will provide a much more open and louder sound. Knowing your setup will help me understand better. How old are the LS3, are they still under warranty? TL

After looking around quite a bit, I think I'm sold on a pair of OS850 speakers. The reviews on these seem to be very good. What kind of power source would work best with these? I would like to connect an ipod and stream satellite radio thru them. I do have a 'boom box' type radio but I'm not sure they will work properly with it?! What would you recommend? Thanks.
1 Answers
hi tim Hi Mike, We recommend our AMP200 that features audiophile quality sound and automatic source switching so you can connect both your iPod and stream satellite radio. What ever you connect to input #1 takes priority while that source is active. When you turn it off, Input #2 becomes active (between 3 to 15 seconds after shutting your #1 source off; there is knob that varies the delay). We also offer CL3-rated speaker wire approved for both in-wall applications as well as direct burial. Terminate the OS850 with our Aqua-Blue connectors and you will be set. The OS850 connects to the Speaker A output, and you still have Speaker B to connect additional speakers as well. Note that the AMP200 is a High Current model that features a 2-ohm rating. If you have the room or need, you could easily connect two pair of the OS850 speakers in parallel (creating a 4-ohm load) and the amp would have no problems playing as long and as loud as you want.

I had the Omni OS650 for over 20 years. When it came time to replace I went back to Omni as a proven product. I liked the 360 sound and wanted a more substantial speaker for my next purchase. Speaker Outlet offered the new OS850 and I ordered a pair back in April. Danial in customer service did an outstanding job in keeping me informed while encountering some manufacturing delays. % stars for customer service. I got my speakes just in time for a weekend party. The installation was easy since I was replacing like product. turned on the stereo and WOW, these speakers are pretty cool. These are so good, when going from inside to outside of the house, there was no loss of music quality. One of my guest even commented that the outside sounded better than the inside. During the delay, I thought I would change to a directional speaker. Danial again was helpful in advising me that if I liked the old Omni 360 these would be well worth the wait, and he was right.
