Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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.
