Easy to set up and compact in size, the D12 speaker can be placed in your living room, study room, dining room, or bedroom. Just connect to the power supply, and it's ready to use! The speaker casing minimizes acoustic resonance and produces an excellent sound. Featuring an RCA/AUX input port for versatile connectivity to external devices such as TV, turntable, DVD, and a line out if you ever want to add an extra subwoofer or active speakers. The D12 can also be connected wirelessly with your smartphone or laptop with the help of Bluetooth 5.0 connectivity. Three top-mounted knobs (Bass dial, treble dial, volume control/input selector) allow for simple, accurate control of the treble, bass, and volume/input. An easy-to-use remote control is included so you can quickly adjust the volume or switch to the mode you want: movie mode, music mode, or other input models.
