The BTP525 water-resistant wireless Bluetooth® patio speakers from Outdoor Speaker Depot are smart buys for patios, decks and pool areas. They're ideal for use indoors and outdoors, and they're available in black or white so you can create the perfect look for your sound system. These Bluetooth® patio speakers feature a single connection for a Bluetooth®-enabled device, and the pair includes a 25-foot AC power supply (please see diagram in above photos). These speakers also come with 10ft of speaker wire so you can place them on opposite ends of your space. We also add innovative weather resistant cap to better protect the speaker connection. The aluminum grilles on these speakers are specially treated to be weather resistant; but for locations where corrosion is more likely to occur, like near the beach, we suggest applying Clear Coat (spray paint only, not brush) to the grills to help fend off the damage that may occur near the ocean.
