Coulomb’s Law in action, the force resulting from a significant difference in the accumulated electrostatic charge between garment and wearer. Harnessing this force in a speaker would require ...

On demo for the first time – and ahead of their official summer launch – will be a pair of new Quad ESL-2912X electrostatic speakers. It's the first Quad electrostatic speaker released since ...

An electrostatic loudspeaker uses a thin plastic diaphragm residing between two perforated metal sheets (the grids or stator plates). The audio signal is applied to the grids out of phase.

With no voltage, sound passes freely. Applying a voltage across the assembly produces ions and moves air with very low inertia, unlike a typical speaker. By controlling the reverse pressure of air ...

If you've been in two minds about getting tickets to this year's Bristol Hi-Fi Show, then this exciting hi-fi news should seal the deal. Quad and Wharfedale will be demoing three of its biggest recent ...
