When do you expect the granite grey RS850 to be in stock? 
1 Answer
Hi Angel:

These will be out of stock for the next 90 days. The Sandstone Brown stock is low and will hopefully be back in stock with the RS850 Grey in time for the Spring selling season.

We are not tech savvy people. Does the speaker just need to be plugged into an AC outlet? Can I connect via Bluetooth to my android and Kindle?
1 Answer
Hi Linda:

The RS850 are our top of the line rock speakers, but it is a passive design that needs a powered (or amplified) signal from an Amplifier or Reciever to play music. We do have another pair of 8.0" passive rock speakers as well, our model RX805, which also needs a powered signal. Thes speakers are the basis of a Bluetooth Rock speaker kit featuring these same speakers; a model BTR-805 (Bluetooth Rock). It features a Master 8.0" Speaker that needs to plug into an AC outlet. Which delivers power to both an internal Bluetooth Receiver and a two-channel stereo amplifier. One channel connects to the inner 8" coaxial (2-way speaker). There is a speaker wire that runs from the Master Speaker to the matching Satellite Speaker (same as a single RX805 rock speaker) carrying the second stereo channel. So your Bluetooth enabled devices (Smartphone or Tablet) connects wirelessly to the Master Speaker's Bluetooth Receiver. The Master and Satellite Speakers should be placed between 8 to 12 feet apart for the best stereo separation.

I hope that is not too confusing,

My pool area is 40x50. Is the RS850 overkill? I’ll have 4. 1 in each corner. Also, which amp do you recommend?
1 Answer
Hi Tony: I would recommend a combination of our AMP300 and a Pre-One Preamplifier. The reason I suggest adding the Pre-One is so you can switch the input signal to Mono since you will have a long distance between each RS850 (a great choice). I also highly recommend adding our NERO Link Wi-Fi streamer as one of your sources connected to the Aux input of the Pre-One. I can explain further if you would like to discuss your setup; TL/5492

I have a small like 40x40 backyard that we like to do outdoor movies in. We have a blow up screen and projector. Im looking to setup some kind of speaker arraignment so that we can get loud enough sound to hear with out overpowering the neighbors. We currently just use a couple blue tooth speakers but the sound isnt loud enough. Would you suggest these speakers as an option? if so how many do you think we would need?
1 Answer
Hi Chris: RS850 is an excellent speaker. And if you were looking for just a single pair, they are a good choice. But what else can you tell me about your setup? Is there a pool, Firepit or a dedicated viewing area to consider? Are you designing a sound system to support your movie night only or something to enjoy anytime you are in your backyard? I would be happy to discuss the complete plan with you.; think about a rough drawing of your layout, possible blueprints or images from different angles. Also, have you considered what you want to use as your source or sources? TL/5465

What’s the main difference between the RX805 and the RS670 rock speakers ? I bought two of the RS670 last year and one stopped working
1 Answer
Hi Bill: The RX series is our entry level Rock speakers. The RS is the step up usually featuring a more elaborate cabinet and more expensive internal components. The RX805 features an 8.0 driver; the RS670 has a 6.5" driver. Both have a low frequency down to 35Hz. Note: the RS850 is our top of the line rock. Did you attempt to replace the single RS670? It does have a 1-year warranty. Try contacting our RMA department. TL/5207

which speakers would you recomend as best option to be powered by a Sonos amp? I have a set of Bose now and I need the volume up very high before they get rocking. No pun intended.
1 Answer
Hi Mario: Your best bet would be the RS670 one because they are in stock (the RS850 are out to July). Plus they are more efficient at 90dB sensitivity and would be better matched to your SONOS Connect Amplifier which is limited to driving a single pair at 55 watts per channel. The RS670 are rated to 150 watts. A problem with most outdoor setups is they try to get away with one big speaker instead of multiple speakers strategically placed around the pool area, like near the hot tub area, outdoor barbeque, fire pit or even just to cover the pool. We would be more than happy to make some recommendations based on your application. Let me know if I can be of further assistance. TL/ 5004

Will a 100 watt sherwood amp handle these speakers?
1 Answer
Hi Denny: Yes the Amp will power these speakers but if it is the typical Sherwood Amplifier/Receiver it will say that if recommends 8 or 16 ohm speakers. Which means this is a chip amplifier that has no headroom, no guts and will not provide enough output to take full advantage of these speakers. And you are limited to a single pair with no ability to expand. You should take a look at our AMP200 where you will get plenty of output plus have the ability of adding a second pair and get even more output/coverage. You you could even look at a smaller pair of rocks and power three pair with the AMP200. TL/4379

I have a pair of your rock speakers that have been outside for about 10 years one now has a "deteriorated cone surround" sound. I'd like to replace just that one but all the models have changed. (more than once I believe)the box that the speaker came in is labeled SPGS8##HYPCBG 8" Rock Gray with HYPE in an oval. I did another system for a friend a few years later and bought HF9's I believe that seemed to be the same. Is this RS850 the same as those?
1 Answer
Hi Don: I am not familiar with those model numbers. There is a HF9 speaker from another manufacture with a similar speaker. Both 8" 2 way rock speakers. Our enclosure is a little wider and not as high. The RS 850 is our best selling/Sounding rock speaker in our lineup.

How far should these speakers be spaced apart - 10-12 ft? RS850 High Fidelity 8.5" Rock Speaker
1 Answer
Hi Paul: Think of a triangle, we recommend 10 to 12 feet apart especially if you are going to be 10 to 20 feet away from the speakers. If you are farther than 20 feet away you could go to 15 feet apart but no more than that. Even at 10 to 12 feet you should angle the speaker in towards a central point at the tip of the triangle. The key is to have the Tweeter focused on that center point. TL/3856

I am looking to purchase rock speakers as a gift for a friend. But do all of these wireless bluetooth speakers need to be connected an amp? Maybe I am looking at the wrong thing. Can you suggest a good pair or wireless bluetooth speakers please. Thank you.
1 Answer
Hi Stacey: These speakers feature a built in Stereo Power Amplifier and Wireless Bluetooth Receiver that are both contained in the master /sync speaker. Therefore it has a external waterproof power supply with a 25 foot cord that powers both the amp and receiver and needs to be plugged into an AC outlet. The second or satellite speaker has to be connected to the master/sync speaker to provide left and right stereo sound (25 foot cord supplied). It syncs up with any Bluetooth enabled device one device at a time. Bluetooth range: 120 feet to 150 feet with an unobstructed line of sight; 50 feet to 75 feet when obstructed. Your results may vary depending upon your actual surroundings. I hope that answers your question TL/ 3737

Hi Bill: The BTR-800TT will not be able to Sync up together. The Bluetooth enabled device will only sync up to one or the other not both at the same time. Our BTR-800 Bluetooth Stereo pair has two speakers one being the master which includes built in stereo amplifier plus Bluetooth Receiver. And a second speaker that has to be hardwired to the first (master) speaker. They should be 8 to 12 feet a part for proper stereo separation.

September 12, 2015
I purchased your BTR-800 rock speakers and for some reason it does not appear I am getting power to them. Your guide talks about having the speakers fully charged, How does that come about? Do the speakers have to be plugged in for a period of time? The connection from the power supply to the master speaker is very difficult to engage and I am not sure if it is fully connected, could this be the problem? Could the transformer be malfunctioning and if so how would I check to make sure it is functioning properly. Thanks Chuck R
1 Answer
Hi Charles, The BTR-800 speakers do not need to be charged. It could be that you don't have the plug facing the correct direction. If you look closely at the end of the plug from the power supply, you will see that there is a flat edge on one side of the circle that matches the shape of the input on the rock speaker. Make sure to line up the edge on the power supply with the edge on the speaker and push it in all the way.

I too am wanting to use Sonos. Would I be better off just using a Connect and attaching it to an amp/receiver to use the larger rock speakers? We have a very open, large area that I had planned to use 2 of the RS850's and then just use a Connect Amp on the smaller outdoor patio speakers. What do you suggest?
1 Answer
Hi Stephanie: I would suggest purchasing our OSD-AMP200 and two OVC300 Volume Controls. And using a single SONOS connect to the AMP200 and have it power your RS-850 Rock speakers on Speaker A and then connect your Patio Speakers to Speaker B output. The Volume Controls should be located somewhere near each pair of speakers. This will allow you to adjust each speaker pair to the other. You can get away with just connecting the AMP200 directly to the two pair of speakers and using the SONOS Connect as your source. TL-2144

I have a 2x100W 8ohm amp to power speakers for a very large outdoor area. Because of the large area, I generally play at fairly high volume, which seems to shorten the life of the speakers. How do I choose between the 850, 840 and 805 speakers for this application?
1 Answer
John, Thank you. Well all of our 8" rock speakers can handle anywhere from 175 - 300 watts, so if you're only going to push each speaker with 100 watts, you wouldn't be playing them to their full potential, but you can get the job done. RS850 is our highest quality rock speaker, so this will give you the best sound out of the 8" models, but you will get the best outcome with a high current amplifier such as our AMP200. -BM 2090

Hi Denny, The RS850 outdoor rock speaker is our top of the line model in that category. It has higher volume capability; a larger tweeter for the highs; and the frequency response goes slightly lower, which translates to more bass.
