The Edifier R1855DB speakers come with a fully functional remote control for the bookshelf speaker set. You can adjust the volume, switch the inputs, mute the speakers all with your fingertips. Inputs are accessible with clear and concise functionality in addition to the manual. Bringing back old-school design with the latest technology, the Edifier R1855DB is an active 2.0 bookshelf speaker system with a 10-degree angle to accurately direct the sound towards you. The corner design directs the sound from the woofers directly to your ears, producing 70 watts of balanced quality melodies. The 4-inch midrange woofer speaker drivers provide rich lows, while the highs produce clear highs.
