Lifetime Tech Support

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.

What's on your mind?

Ben • 12/17/2019, 2:17:43 PM Are these loud enough to host a party where 75+ people are attending in a backyard?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Ben: Depends on the party, if your are just looking for background music, maybe. If you are establishing a dance floor and you can set these up at 10 to 12 feet apart, maybe. We also have the BTP-650 the patio speakers that can be mounted above the crowd. I would hate for you to have to buy either of these with the party as your measuring stick. TL/3784
Robb • 12/17/2019, 2:17:43 PM Are the two speakers hard wired together? Is so, is the wiring rated for underground burial and for the elements?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Robb: Yes the two speakers are hard wired together to produce stereo sound. The wire has a heavy duty jacket suitable for burring. There are also weatherproof covers for the speaker cable connection on both the master speaker as well as Satellite speaker. Good Luck TL/3806
Jeff • 12/17/2019, 2:17:43 PM Can you hook other single speakers to the main also? I would like 4 total speakers working together. So main and then 3 singles? Thanks
Customer Service • 12/17/2019, 2:17:43 PM
Hi Jeff: Good question.... Currently all our models have a built in Stereo Amplifier with one channel connected to the internal speaker (the right channel as an example) and a single output for the Left channel for true Stereo separation. The internal amplifier is meant only to power a single pair of eight ohm speakers. We have been looking into Bluetooth technology where the Bluetooth receiver has a built in extender so it outputs the stereo signal to a second Receiver (not sure if this is by WiFi or Bluetooth). Another possibility is to have a built in four channel amplifier with three outputs, one matching the internal amplifier and then another for right and left stereo to connect to a second pair of passive speakers. But I need to do more research, but as it stands we are limited with our current lineup to a single pair of Rocks, Patio and Frogs speakers. Stay Tuned TL/
Dave • 12/17/2019, 2:17:43 PM Can the power be left turned on the main speaker for long periods of time even when not in use?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Dave: Yes you can leave the speakers on for extended periods. The current draw is minimal while it is in stand by mode waiting for new audio signal. TL/3894
Guy • 12/17/2019, 2:17:43 PM Does the speaker wire have to be buried?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Guy: Only if you want to hide it, Our CL3/FT4 (12, 14 or 16 gauge) rated speaker wire can be buried in the actual ground, in a buried conduit or above ground. TL/3919
