Acoustics, Lumia, and Electrics All-in-One System - Edifier QR65 speakers. High-quality acoustic architecture, with Hi-Res Audio and Hi-Res Audio Wireless certified, and supporting LDAC. Splendid preset and custom light effects. Safe and high-efficiency USB charging ports, powered by TurboGaN technology.
With the MDF enclosure, the independent acoustic cavity, and the enhancement by patented MazeTube Bass Reflex Channels and TurbMuff Air Noise Suppression Technology, port noises and acoustic resonance are reduced to the lowest level.
The end-to-end audio process flow supports high resolution audio up to 24bit/96kHz.
The dual TI Class-D digital audio amplifiers provide the precise two-way active crossover, magnify high frequency signals and mid-low frequency signals separately, and manage DRC effectively. The USB-A and the RCA audio input ports support high-resolution audio signals. With the enhancement of LDAC technology, you can also stream high resolution audio up to 24bit/96kHz to this speaker via Bluetooth.
With the bundled aluminum speaker stands, the sound coloration effects can be diminished effectively, which arise from the sound reflection against the desktop surface.

Meanwhile, the design of 10-degree angle is for directing the sound precisely at ear level when the speaker is put on a desktop.
