The World's First Bluetooth Electrostatic Speaker| treVolo
Electrostatic Speaker Technology
Dual Woofers and Dual Amplifiers
Bluetooth® 4.1 aptX® with Line-out function
BenQ treVolo is the best portable electrostatic Bluetooth speaker available with the same technology as high-end listening room speaker. It utilizes a quad amplified design utilizing active electrostatic panels, high quality woofers, and large radiators that are precisely tuned with a custom tuned DSP to deliver truly uncompromising better sound for the wireless compelling audio enjoyment.
treVolo uses the same electrostatic technology that is typically reserved for high-end speaker systems. It was created to reduce harmonic distortion from 10% to less than 1%, representing a tenfold improvement over traditional speakers. The end result is a clean, crisp and beautiful sound
treVolo speaker features a unique technology called TrueSound, that can help improve sound quality on highly compressed legacy audio files. If the speaker's DSP chip detects the loss of higher frequency data due to a low bit rate recording or high compression levels, TrueSound will improve the detail in the higher ranges of the audio spectrum that can be lost on a low bit rate recorded file.
CD-quality aptX® Bluetooth® gives you the highest support for Bluetooth® signal transmission, and Line-out feature can turns the speaker into a high-quality wireless Bluetooth® signal receiver. In the way you transmit CD-quality sound wirelessly from your smart devices to your existing Hi-Fi system.
