The RS100 wireless speaker allows you to easily add streaming music capabilities to any room you want. It features DTS Play-Fi® technology that gives the freedom and flexibility to wirelessly play the music on your mobile devices over your existing Wi-Fi network. Simply connect the RS100 to your Wi-Fi network, install the free Play-Fi Apple or Android mobile app or Windows desktop app and then you’re ready to stream your music. The RS100 is a great first piece to introduce yourself to McIntosh’s legendary sound quality and performance standards (standards not found in any other Play-Fi device except our MB50 Streaming Audio Player). A single RS100 is all that is needed to start building your wireless speaker system; more can be added over time to expand your system. Up to 16 speakers can be connected to a single Wi-Fi network - enough for stereo playback in 8 separate rooms. With the Play-Fi app installed on all your devices, each device can stream different music to each room, giving all family members or guests control over what they want to hear in their room. Besides accessing your personal music library, the apps have built-in support for many leading online streaming services1 including Amazon Prime Music, Deezer, KKBox, Pandora®, QQMusic, Rhapsody®, SiriusXM®, Songza, Spotify® and TIDAL (subject to change), letting you enjoy all your streaming music on your RS100.
