Edifier's S3000 Amplified Bookshelf Speaker System allows you to create the home audio setup you always envisioned—without the tangle of wires. Bluetooth 5. 0 with aptX provides better power consumption, 4x the range, twice the speed, and 8x the throughput of older Bluetooth systems. That means better, more consistent audio quality with less distortion. KleerNet wireless technology is used to transmit the audio from the powered speaker to the other—no wiring involved! Plus the S3000Pro is Hi-Res Audio certified for higher bit depth and sample rates of 96 kHz or higher. The speakers' matte black finish and dark wood paneling create a look that combines hi-tech modern sensibilities with rustic, old world design. Together, luxury and function combine to form a complete package that will complement any style of decor. Bass, treble, and volume dials located on back of the active speaker. 6. 5 in. aluminum alloy diaphragm cone base and 3 in. planar ribbon tweeter in each speaker.
