Vented diaphragm: Grado headphones have a vented diaphragm
design for a large, airy, three-dimensional sound. The wooden air chambers are
hand-crafted at Grado's labs from a specially selected species of mahogany. An
intricate procedure of curing is done between production steps to achieve optimal
Drivers: The diaphragm is made of a low mass polymer,
developed with the suspension's compliance in mind, to achieve the desired
low frequency response. The diaphragm's total mass is designed to provide
a full 20 kHz bandwidth, while avoiding break-up at lower frequencies. High
power neodymium magnets maximize efficiency and minimize weight. The left
and right drivers are matched to within 0.05 dB for exact imaging.
Voice Coil: The GS1000i's voice-coils are wound from ultra-high
purity, long crystal (UHPLC) oxygen free copper. This high conductivity copper yields
a clear transmission and minimizes coloration, resulting in smooth, clean and dynamic
Connecting Cord: Grado also uses UHPLC copper in the cable.
The new 8-conductor cable design improves the control and stability in the upper
and lower frequency ranges.
G-Cushion: The GS1000i's over-ear cushion design creates a
virtual room where your ears sit. The result of this room is a more spacious
soundstage, and long term comfort.
