This is the 2nd generation of our Bluetooth® Rock Speakers, we made the following changes a) Using better sound rock shell from our most popular rock speaker RX805 with better bass and clear high ends. b) Using waterproof IP67 grade power supply for better outdoor durability.

Get ready to jam in any outdoor space with the BTR805 Wireless Bluetooth® Rock Speaker . This 8" set is ideal for your lawn, garden or patio for best bass; they come in Granite Grey or Sandstone Canyon Brown so you can coordinate without the speakers looking out of place.

There are two speakers, a master and pairing speaker. The master speaker has the internal stereo amplifier plus built in Wireless Bluetooth® Receiver. The second or pairing speaker is connected to the master speaker using the 10Ft speaker cable that is included with the kit. The result is a two channel stereo output. It is recommended to have the speakers 8 to 12 feet apart for best stereo dispersion. You can cut the 10Ft cable down to the exact length desired. The extra cable is supplied in case you have to be created to hide the wire when running it between the two speakers.

Martin • 12/17/2019, 2:17:43 PM Can these speakers connect to home receiver though wireless streaming like through a SONOS connect or HEOS
Customer Service • 12/17/2019, 2:17:43 PM
Several of the Aventage Yamaha receivers have both Bluetooth reception and broadcast capability, so you can drive the speakers from the receiver if the receiver is connected to the Internet instead of streaming through your cell phone. In this case, the receiver would stream say Pandora from the Internet through the receiver to your Bluetooth speakers ... avoiding cell phone data charges. And you can use the Yamaha cell phone app to control the receiver. However, the catch is the distance which is about 30 ft without any interfering walls or objects. So you may need a Bluetooth amplifier to boost the distance to 100 ft. plus. You can Google several different amplifiers that should work and buy them off Amazon.
Glen • 12/17/2019, 2:17:43 PM I purchased a pair of the BTR805's a year and a half ago and absolutely love them. Unfortunately here in South Texas the sun gets very hot and the Bluetooth range on my speakers is probably 15' at best. Setting my phone out near the speakers is a real pain as I have to hide it under a chair to keep from overheating and stopping. Is there a way to extend the Bluetooth range? The whole idea was to sit at the patio table and eat with music playing but the table is about 25' away and there's no way the current Bluetooth in the system can reach it.

Hi Glenn: Check out this link regarding Bluetooth connection for Android. All our Bluetooth Speakers are Bluetooth 3.0. TL/
Scott • 12/17/2019, 2:17:43 PM A squirrel (or some other rodent) chewed thru my power cords. Do you sell the power supplies? If not, is there a recommendation
Customer Service • 12/17/2019, 2:17:43 PM
Hi Scott: I am sorry to hear that. Two options, one is to take a picture of the Power Supply so we can check if we still have a matching replacement in our RMA Department. The second option would involve taking the unit to an audio Video Repair shop and having them splice the cable back together and maybe add an extension piece. They could also test the power supply to see if it is still good to go. Send the image to I would follow up with the RMA department. TL/5175
ashish s • 12/17/2019, 2:17:43 PM any alexa enabled speakers available - linked via voice, the alexa app, and amazon music
Customer Service • 12/17/2019, 2:17:43 PM
Hi Ashish: According to this link they say the AMAZON Echo does have an internal Bluetooth Transmitter built-in and you can command to connect to Bluetooth which then disables the internal speaker: An external speaker connection can be achieved wirelessly via Bluetooth or wired through the 3.5mm audio jack on the back of the device. The issue around using the 3.5mm jack is that, when a 3.5mm cable is connected to the Echo Dot, the internal speaker is completely bypassed, whether or not your wired speakers are turned on. This means that, when using a wired connection, your wired speakers must be turned on if you ever want to use the Echo Dot. On the other hand, with Bluetooth speakers, the Echo Dot switches back to its internal speakers when the Bluetooth speakers are turned off. Even if the Bluetooth speakers are on, you have the flexibility to sever the connection hands-free by simply asking Alexa, so you can switch back to the internal speaker at will. If you have your heart set on using wired speakers with the Echo Dot, there are things you can do to make wired speakers a lot more convenient. So you can use the AMAZON ALEXA connection to broadcast the audio signal via Bluetooth to any of our Bluetooth enabled speakers including broadcasting to our NERO XS integrated amplifier with built-in Bluetooth Receiver.

JO • 12/17/2019, 2:17:43 PM How long is the power supply cord? I want to make sure they will reach the plug from the shrub bed.
Customer Service • 12/17/2019, 2:17:43 PM
Hi JO: The Power Cable breaks down as follows: the cord from the AC plug to the actual Power Supply block is just under 4 feet. The cable from the block to the speaker is around 16 feet. Then there is a short pigtail (under 2 feet) coming from the bottom of the speaker which has a waterproof connection to the Power Supply Cable. TL/5309
