treVolo 2 is a Bluetooth speaker with Electrostatic Diaphragm Technology that permits high-end acoustics in a compact sized speaker. The bass woofer can increase 5 dB of acoustic pressure with the same wattage, allowing full-toned bass performance with perfect balance. Audio efficiency is increased by 34.5% compared to conventional speakers thanks to the pore design, while the surface contact area is decreased by 98.3% thanks to the vibration absorbing design. The unique wood mount lowers sound wave reflections on the table surface, bringing audio experience to life and sending the music directly to listeners' ears.
