Each speaker cabinet houses one 1" silk dome tweeter and one 4" long-throw mid-low driver. The MDF cabinet can effectively diminish resonance and distortion, further guaranteeing the pure reproduction of audio input. The digital amplifier can drive 15W to each of the stereo pair and provide DRC (dynamic range control). With 24W (RMS) total output power, the speaker can produce enough sound to fill a medium room. The Bluetooth V5.4 audio receiver supports the seamless audio streaming with stable connection. Three preset sound effects are optional by EDIFIER ConneX App for music, movie, and gaming. With the app, you can also customize your own sound effects to cater to your unique tastes.
