High-quality, powerful sound in a compact design: The Luna HD 2.0 bookshelf speakers deliver an impressive total output of 74 watts (RMS). Whether via cable (AUX and optical) or Bluetooth, the individual components work together to create an engaging sound experience. Two woofers and two midrange drivers with a separate passive bass membrane ensure crystal-clear highs and authentic vocals, while the bass is deep and palpable. The Luna HD also filters out any noise even at maximum volume. The included remote control allows you to adjust the volume and bass intensity. To maintain the elegance of the Luna HD without protruding buttons and switches, simple, touch-sensitive controls adorn the side of the speakers.
