About this item

Written by Crutchfield's Eric A.

Powerful rock speakers with built-in Bluetooth

OSD's rugged BTR-805 rock speakers are self-powered and Bluetooth-enabled, so you can play your music outdoors without having to connect to an indoor receiver. And each one has a large woofer and soft dome tweeter for extended frequency response.

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.

Weather-resistant enclosure with potent drivers

These speakers feature rugged rock-shaped cabinets, so they're durable enough to crank out tunes year-round, rain or shine. Each speaker has an 8" polypropylene woofer for big-time bass, and a 1" soft dome tweeter for smooth, detailed highs.
