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 waterproof. Keystone is the way to go for hi-fidelity music outside that’s all upside and no downside.
