CADENCE AMAYA (ES MK II) Design |
|
|
The construction of the electrostatic drive unit is a major technological
breakthrough. The unit is unaffected by humidity, has no charge-up time, is not
susceptible to arcing – and it has an incredible sensitivity of 91dB/watt/1 metre.
No other electrostatic unit even comes close. Several international patents have
been obtained (and some are pending) on The Cadence electrostatic drive unit.

The musical heart of the electrostatic unit is a PTFE membrane that is thinner than
a hair (3.5 microns). It is positioned with the highest degree of accuracy between
two electro-formed stators. These are in turn rigidly held between two aluminium
frames that are machined to very close tolerances. The electrostatic drive unit, in Cadence's hybrid design, is required to work no lower than 950 cycles per second. The second drive unit, the sandwich cone bass driver, is ultra rigid and fast, with a second magnet to improve acceleration. A layer of Nomex honeycomb between two layers of Kevlar guarantees accurate and fast transient response. The whole speaker is housed in a massively constructed bass reflex enclosure with a patented baffling device. `Boominess', a result of undesirable standing waves, is completely eliminated.
