PROJECTION, ORTHORGRAPHIC (GENERAL) - A SYSTEM OF DRAWING AN IMAGES OF AN OBJECT FORMED BY PROJECTING VIEWS AT RIGHT ANGLE FROM ANOTHER VIEW. THIS IS CALLED THIRD ANGLE PROJECTION IN THE U.S. WHERE THE TOP VIEW IS DRAWN ABOVE OF THE PLAN VIEW. THE REST OF THE WORLD USES FIRST ANGLE PROJECTION WHERE THE TOP VIEW IS DRAWN ON THE BOTTOM OF THE PLAN VIEW. THE SYSMBOLS FOR FIRST ANGLE AND THIRD ANGLE PROJECTION ARE DRAWN NEXT TO THE TITLE BLOCK.

Eminence Model Number 820F3031

Coil Diameter 50 mm (2 in)

Gap Height 8 mm (0.313 in)

Magnet Weight 0.85 kg (30 oz.)

Coil Widing Width 14mm (0.55 in)

PolarityA positive voltage applied to the

positive terminal shall cause movement of the cone away from

the magnet structure.

Rub and BuzzNo rubs, buzzes or supurious noises

with 4 Vrms applied at any frequency from 50 Hz - 20 kHz.

Thermal Power Handling (ref)200 W continuous for 8 hours without mechanical failure or

burnout, per AES2-1984 pink noise test, free air.

Mechnical Power Handling (ref)

60Vpk for 100 hours without mechanical failure or burnout, per EV woofer burst sweep power test, 45

Hz - 180 Hz passband, in ZX1i enclosure

Structural Performance (ref)

The woofer must not have any rubs or buzzes after 6 drops at .6 m (24 in) (3 drops in one direction and 3

drops rotated 45°), and no components of the woofer assembly must crack or fall off, per EV woofer

drop test procedure.
