H20 Bluetooth Speaker

The designer of ESD Acoustic discovered that with the same speaker, a reflector baffle provides the low frequency response that a larger flat baffle does, which is friendly to miniaturization. Hence comes the birth of our bluetooth speaker series named H20, Sage and Hermit.

H20 inherits the coaxial field coil unit from Aviator, with total height of 1 meter. It has a 2-inch beryllium diaphragm plus an 8-inch titanium diaphragm. The reflector is made of glass fiber, carbon fiber or other customized materials with 60 centimeters diameter. The electronic part includes two power amplifiers used to drive the mid-high and the bass, with active crossover network.

It is equipped with Qualcomm 5.3 TWS Bluetooth module, which can be wirelessly paired freely to form a stereo system.

The mid-high uses 2-inch world’s only foil beryllium diaphragm by Truextent, bringing higher resolution and lower distortion.

The bass uses ESD’s patented titanium sandwich diaphragm, light and sturdy, and segmantation distortion and phase distortion disappear.

A built-in field coil power supply with AI technology almost cancels out the eddy current, solving this problem which troubles the industry for a century.

The coaxial field coil unit reaches a magnetic density of 2.2T, controlling the speaker with great ease.

The mid-high frequency of the coaxial speaker applies horn curvature that incorporates with the bass diaphragm, effectively reducing distortion.
