Keystone (Pair)

Wireless Solar Rechargeable Outdoor Speaker Pair


Enjoy true hi-fidelity sound outdoors with no complications!

Enjoying music outdoors is great. But getting true hi-fidelity sound from great outdoor speakers has always involved complicated wiring to your inside home stereo. On top of that, you can’t control the volume or program music from outside without running back to the inside stereo. Who needs that! Keystone™ solves everything. First and foremost, this is a real high-fidelity speaker: it has a long-excursion 4-inch woofer in an acoustic suspension enclosure and a wide-dispersion 1-inch soft dome tweeter. Together, they combine for smooth, wide-range response that does full justice to even the most demanding program material. But Keystone doesn’t stop there: It streams music wirelessly from any Bluetooth®device. It’s powered by a long-lasting internal rechargeable battery. Its built-in 40-watt (peak) amplifier provides plenty of music power. Keystone is an outdoor music system that is super easy to set up and leave up all summer long.Other thoughtful touches abound: An embedded solar panel keeps the battery charged. The two speakers wireless link to each other for true stereo—no inter-speaker wiring needed. And of course, it’s IPX4 water-resistant. Keystone is the way to go for hi-fidelity music outside that’s all upside and no downside.

** To determine if the Solar Panel is providing charge to the battery, press and hold the Bluetooth button on the  speaker  (not  on  the  remote)  for  5  seconds.  Once a  tone  is  heard,  release  the  button.  If  the  tone continues to play after release, then the solar panel is providing charge to the battery. If the tone does not continue  to  play  after  release,  the  solar  panel  is  not  providing  charge  to the  battery.  To  optimize  solar charge, expose panel to direct sunlight.
***  Available  range  is  affected  by walls,  obstructions,  and  movement.  For  optimal  performance,  place  the product so it is unobstructed by walls, furniture, etc.
**** If the remote control sensor is exposed to direct sun light, strong artificial light (like from an inverter-type fluorescent lamp), or infrared light, the unit or remote control may not function properly.
