Introducing the new RYOBI ONE+ Hybrid Score™ Wireless Secondary Speaker. By connecting your Bluetooth® device first to a Primary Speaker, you now have the ability to connect up to four additional Primary or Secondary Speakers instantly using SKAA® technology. Note that only 5 speakers can be connected together within the network, and that you must have a Primary Speaker in order to transmit audio through the Secondary Speaker. This speaker features a high-quality driver and passive radiator, so you will always receive clear, robust sound. With up to 150 ft. of SKAA range from a Primary Speaker, a Secondary Speaker can be placed virtually anywhere in the home or on the jobsite and stream through your walls and floors. Control volume levels easily with independent volume control on every speaker, or, control each volume level simultaneously right from your mobile device. Not only is this speaker compatible with any RYOBI ONE+ 18-Volt battery, it also includes an AC power adaptor that allow for endless runtime. Learn more about SKAA technology
