This speaker is the top unit of the Drumfire, which packs quite a punch on its own. It delivers pure hi-fi acoustics with deep, controlled bass and crisp highs. The D-2 is the improved version of the D-1, offering AirPlay 2, Google Cast and Spotify Connect, and even better sound than its predecessor. The D-2 is designed to elegantly blend into any home. Wrapped in faux leather, solid aluminum details and a sturdy wooden cabinet. The multi-room function allows you to play the same music throughout your home. Group and play, set to left/right for stereo pairs. Play them all together - Or not. You choose. Multiroom sound and multi-person operation. The D-2 can be connected to the Drumfire subwoofer or another woofer via cable or wireless if it is a multi-room subwoofer. When you connect a subwoofer, the D-2's crossover changes so that the subwoofer takes over the bass. This way you can play much louder. Streaming services available: Amazon Music, Deezer, iHeart Radio, Napster, Qobuz, QQ Music, Spotify, Tidal, TuneIn, VTuner and many more via Google Cast and AirPlay 2. 6 preset buttons allow easy access to playlists and radio stations.
