OSD BTR-150 rock speakers (single speaker shown) are designed to blend into your landscaping.
Powered rock speakers with built-in Bluetooth
OSD's convenient BTR-150 speakers are disguised as rocks, so they blend in by the garden or swimming pool. They're also self-powered and Bluetooth-enabled, so you can play your music outdoors without having to connect to an indoor receiver.
Built-in Bluetooth for easy streaming and setup
These speakers are ideal for streaming music from your compatible phone, tablet, or laptop. The "main" speaker houses the amplifier and Bluetooth module. It connects to an outdoor AC outlet with the included water-resistant power supply. The second speaker is completely passive and connects to the main speaker with an included run of speaker wire.

Features
Landscape Speaker: The OSD Audio BTR-150 powered outdoor "rock" speakers feature a weather-resistant, acoustic suspension (sealed) enclosure with a powder-coated, rust resistant aluminum grille for outdoor durability. The BTR-150 is designed to withstand all types of weather and perform under some of the harshest conditions.
2-Way Powered Speaker: Each loudspeaker houses a 2" dual-cone tweeter and a 5.25" polypropylene cone woofer, with a Butyl rubber surround, for full-range outdoor sound. The main powered speaker includes a built-in 120 watt amplifier that powers the drivers in both speakers for dynamic sound with low distortion. The passive speaker connects to the main powered speaker via the attached 3' speaker wire on each speaker and the included 10' speaker cable (16' total). Four waterproof wire nuts are provided for connecting the speaker wires.
Built-In Bluetooth: The OSD Audio BTR-150 powered outdoor speaker features built-in Bluetooth 5.0 with support for wireless audio streaming (A2DP). You'll be able to wirelessly transmit audio from your Bluetooth-enabled smartphone, tablet, laptop, or desktop computer to the outdoor speaker system. You'll still control music playback and view song/artist/album info from your source device (not the speaker). Only one source device can be paired, connected, and used for playback at a time. The speaker system has a wireless Bluetooth range of approximately 30' to 50'.
Note: The BTR-150 does not offer a wired source input.
Outdoor Mounting: Each speaker is designed to look like a rock, allowing them to blend in with your yard, garden, or landscape area. The speakers feature a wide flat bottom for placement on a flat surface while remaining upright and stable.
Power Requirements: The main powered speaker needs to be located near an AC outlet where you can connect the included power supply to the speaker in order provide the electrical current needed for the built-in amplifier and built-in Bluetooth receiver. The AC power supply features an attached 3.5' cord that plugs into an AC outlet and a 16' cord that plugs into the back of the main powered speaker.
- When mounting the power supply outdoors, you must use a GFI protected AC outlet with "in-use" waterproof cover.
- The power supply is IP67-rated and waterproof. As a precaution, try and limit the power supply's exposure to harsh weather, water spray, and other outdoor elements.
Note: The BTR-150 does not include a power switch and will be powered On when plugged into AC power.

The price is right, the setup is simple, and the sound is profound! Not much more to say. Placed in a large planter outside a long fence next to our 20 x 40 in-ground pool. The sound is amazing no matter where you're standing.
