Fostex TH1100RP Premium Open-Back Planar Magnetic Headphones

TH1100RP Premium Open-Back Planar Magnetic Headphones, by Fostex.

This product is the flagship of the RP headphone lineup, carefully assembled at a factory in Japan with the latest Fostex-developed premium grade RP planar magnetic driver built into a solid wood housing dyed with Aizome indigo from Tokushima, known as the representative indigo dyeing process in Japan.

The one-of-a-kind texture of the traditional Aizome, which brings out the beauty of the individually different wood grain, and Fostex’s RP technology, a flat diaphragm that has been used for 50 years, play together in this headphone flagship.

RP and RP technology are proprietary Fostex technologies that move the entire surface of the planar diaphragm in regular phase.

The RP technology planar diaphragm driver technology, developed in 1974 and continually refined ever since, has a newly developed planar diaphragm, much larger than the conventional RP driver used in T50RP mk3 / mk4.

In addition to increasing the number of magnets that sandwich the diaphragm, as well as a newly designed pattern and shape for the printed coil, the magnetic circuit components have been redesigned to optimize the magnetic flux distribution.

All of these work together to suppress unwanted resonance in the diaphragm. This simultaneously achieves high sensitivity, smooth frequency response, and excellent transient characteristics, enabling accurate and delicate reproduction from heavy bass to high frequencies, and the ability to express a clear sound image in space with a clear sense of localization.

The solid hard maple wood housing, known as a material for guitars, is dyed with Awa Aizome from Tokushima, which has long been valued for its high-quality dyeing. The wood is carefully dyed one by one by skilled craftspersons, resulting in a deep indigo colour that beautifully reveals the unique grain of the hard maple wood.

Dyeing with Aizome, made exclusively from the indigo plant, allows the hard maple’s density and specific gravity to take advantage of its properties that do not add unnecessary colour to the sound, allowing the player to user a firm, deep bass range and clear, extended treble range.
