Utilizing a newly designed flat-diaphragm RP mk2 driver with Air Dumping Control for superior sensitivity and improved transient and frequency response, the TH1100RPmk2 from Fostex are premium planar audiophile headphones with an open-back design. Sporting a solid maple wood housing with a distinctive Japanese Hon-Ai indigo dye finish, the TH1100RPmk2 is as much a tool as a work of art.
The TH1100RPmk2 delivers accurate and delicate reproduction of everything from heavy bass to ultrahigh frequencies, for a clear sense of localization and an ideal soundstage. Newly adopted magnesium alloy mechanical parts in the housing base plate and hanger help to reduce the weight of these headphones by 20% compared to aluminum components. Comfort over long listening sessions is an important factor, which is why the TH1100RPmk2 features comfortable silk-protein synthetic leather earpads and a plush sheepskin headband. The detachable Y-cable features gold plating on the 1/4" end and 3.5mm TS connectors for the earphones. These headphones include a leatherette pouch.
This simultaneously achieves high sensitivity, smooth frequency response, and excellent transient characteristics, enabling accurate and delicate reproduction from heavy bass to high frequencies, thereby realizing the ability to express a transparent sound image in space with a clear sense of localization. And new to the updated driver is an air dumping control that achieves better diaphragm amplitude, particularly in the low frequency range. This makes for even better bass response for a warmer soundstage.
Dyeing with Hon-Ai, which is made exclusively from the plant indigo, allows hard maple’s heavy specific gravity to be utilized without adding unnecessary color to the sound, allowing the user to enjoy deep bass and clear, extended highs.
