Electrostatic speakers
The electrostatic speaker uses a thin conductive diaphragm
driven over its whole surface by an electrostatic force. As
rigidity is not a requirement the mass can be extremely small,
so the response to transients and high frequencies is almost
immediate.
With all parts of the surface being driven, there are no
break-ups or spurious movements such as experienced with a
cone.
In Britain, QUAD is virtually synonymous with the
electrostatic speaker, but there are many other makers in the
field, especially in America.
Bias When a voltage is applied across two conductors having
a large surface area in close proximity the ...
