The casing of the Airpulse A300Pro speakers is made from elegant 25 mm thick, high-strength walnut veneer, featuring a 36 mm thick sound-absorbing interior lining that optimizes the absorption of excess standing waves to minimize sound coloration and deliver a natural, uncolored sound. The speakers are equipped with a refined horn-loaded aluminum ribbon tweeter that fills every corner of a room with clear and harmonious high frequencies. An improved 6.5-inch magnesium-aluminum woofer, supported by a 50 mm diameter voice coil and an advanced heat dissipation mechanism, ensures minimal distortion at maximum dynamics, resulting in very detailed and deep-reaching tones at any volume. The connection between the left and right speakers utilizes Kleernet wireless transmission technology to enable lossless wireless playback. Combined with the Qualcomm QCC3031 Bluetooth receiver, the A300Pro guarantees high-quality and faithful reproduction when streaming from your smartphone, tablet, PC, or laptop. In addition to the standard wireless left/right stereo configuration, the A300Pro speaker system also offers an independent configuration for left and right as traditional monitor speakers, typically used in mixing consoles and professional recording studios. The Airpulse A300Pro speakers can be connected to your audio equipment via RCA, optical, coaxial, USB, and XLR. With the included remote control, you can conveniently switch between sources, adjust the volume, and turn the speakers on and off from your couch. Alternatively, you can customize the bass, treble, and volume of each speaker using the controls on the back of each speaker to create an immersive listening experience.
