Sundfield Spatializer osimulates a larger soundstage with the touch of a button. This unique feature creates wide-filed sound by optimizing each channel, sending out opposite signals to eliminate mutual interference and improve separation.
30W + 36W RMS undistorted power, 4 inch woofer, and 19mm silk dome tweeter, the Edifier R1700BTs active Bluetooth bookshelf speakers make even the hardly-noticeable sounds very clear. And the DSP(Digital Signal Processing) and DRC (Dynamic Range Control) helps to minimize distortion for improved audio even at low volume.

When connected the sub-out automatically detects the subwoofer and activates the digital crossover. Dual RCA inputs allow you to connect to two devices at a time. Connect to your devices such as phone, PC, laptop, tablet, or gaming console with RCA to RCA audio cable, and 3.5 mm-RCA audio cable, eliminates the need to switch cables.
Convenient dials on the side panel of the speaker allows you to adjust the bass, treble, and volume, press the volume dial to toggle between inputs.
