This advanced Bluetooth speaker is a must-have for those who value HiFi sound quality. The device boasts impressive features such as a foldable electrostatic speaker, electronic crossover, and 2.1 stereo. It also comes with an 8-inch subwoofer for unparalleled bass output. The speaker is Bluetooth compatible with most mobile phones and provides a seamless listening experience. With publication in 2024, this is a state-of-the-art DSP device that will keep you entertained for years to come.
The feature of this speaker is that it can still produce delicate treble and deep bass at a small volume.
It is recommended to add another speaker shelf and place it in the corner of the living room or bedroom to emit the sound of petty bourgeoisie at will.

Ten years ago, I first heard the wonderful sound of the UK QUAD electrostatic speaker, and the expensive price led me to embark on the DIY journey.
Firstly, various electrode materials were screened, including perforated steel plates, aluminum plates, metal screens, etc., and finally, double-sided PCB copper-clad plates were selected. Practicality, strength, and conductivity can be achieved in one go.
Secondly, the Japanese Dongli PET film with excellent tensile strength was selected as the diaphragm for the electrostatic speaker. The conductive material on the diaphragm was determined through N experiments.
Finally, in the production of step-up transformers, we tested various diameters of enameled copper wires and silicon steel sheets, and different wire diameters produced different sounds. The high frequency range of fine wire diameter is rich, but the lower limit of mid to low frequencies is not enough; The medium and low audio frequencies with thick wire diameters are good, but the extension of high audio frequencies is not enough, and it also increases the volume and cost of transformers.
The final choice is to use a 35 watt medium to high frequency step-up transformer and a 350 watt full frequency step-up transformer.
Nowadays, we can produce electrostatic mid to high range speakers, electrostatic full range speakers, and electrostatic headphone boards at a good price, providing them to audio enthusiasts around the world.
