Fostex TH1100RP: Flagship with advanced RP planar magnetic driver technology

The Fostex TH1000RP is a flagship model that showcases Fostex’s advanced RP planar magnetic driver technology, carefully integrated into a solid wood housing. This exceptional product is the result of Fostex’s 50 years of experience in developing RP planar diaphragms.

Each pair of headphones is handcrafted in Japan and features a unique texture achieved through the traditional Aizome dyeing method, renowned for its deep indigo color and ability to highlight the natural grain of hard maple. This dyeing process not only enhances the visual performance, but also preserves the acoustic properties of the wood, delivering unparalleled sound quality.

The main feature of the TH1000RP is a new planar diaphragm, significantly larger than previous models, combined with an optimized magnetic circuit. This ensures high sensitivity, flat frequency response and excellent transient response, creating accurate and detailed sound reproduction over a wide frequency range from deep bass to high frequencies. The thoughtful design ensures a clear sound image with precise localization, making these headphones ideal for both professionals and audiophiles.

Another distinctive feature of the TH1000RP is the hard maple body, painted using the Awa Aizome method from Tokushima. This paint, made exclusively from the indigo plant, allows the headphones to retain their natural acoustic properties while still looking impressive. The deep indigo shade, unique to each pair thanks to the hand-painting process, highlights the beautiful texture of the maple, making each pair of headphones unique. This process not only adds aesthetic value, but also ensures that the sound quality does not suffer from unnecessary color changes.

In addition to the acoustic and aesthetic qualities, the TH1000RP features new lightweight magnesium alloy mechanical parts, reducing the overall weight by 20% compared to traditional aluminum parts. The weight reduction and the use of rubber bands to reduce vibrations increase wearing comfort. The new ear pad design and flexible upper cushion, made from high-quality materials such as soft, low-impedance cushions and genuine sheepskin, provide comfort even during long listening sessions. The inclusion of high-purity OFC cable and the ability to have balanced connections further improve the overall performance, making the TH1000RP a premium choice for discerning listeners.
