Dome Super Tweeter

T250D

Features

The world first dome super tweeter em- ploying ø25mm pure magnesium dia- phragm.

Low distortionand high power magnetic circuit with combination of the copper- plating york/plate and the tripled ø90mm large ferrite magnets.

Up down roll tangential surround is to re- alize less anti-resonance and superior am- plitude characteristic.

Wide range and high input design.

High-density resin frame with the shape designed to minimize the distance be- tween the tweeter and a woofer for more accurate sound image.

Fostex is well-known in the audio industry for its high-quality speaker components, including its dome tweeters. These tweeters are designed to reproduce high frequencies with precision, clarity, and a broad dispersion pattern, making them a favorite among audio enthusiasts and professionals alike.

One of the main features of the Fostex dome tweeter is its lightweight and rigid diaphragm, typically made from materials like silk, aluminum, or metal composites. This design allows for quick movement and exceptional response times, ensuring that even the most intricate details in the audio playback are preserved. The dome shape is engineered to provide a smooth frequency response, making these tweeters capable of handling frequencies well into the upper ranges, often exceeding 20 kHz.

Fostex tweeters are also known for their remarkable power handling capabilities. Many models boast a significant power rating, allowing them to be paired effectively with a wide range of amplifiers. This feature is particularly advantageous in professional settings, where reliability and performance under various conditions are paramount.

The technologies employed in Fostex dome tweeters often include advanced voice coil designs and high-quality magnetic circuits. The voice coil is typically constructed to ensure minimal distortion, leading to a more accurate sound reproduction. The integration of high-temperature materials helps enhance the longevity of the components, making them a wise investment for audio systems.

Another key characteristic is the wide dispersion pattern provided by the dome design, which ensures that sound is distributed evenly across the listening area. This trait is especially beneficial in home theater and studio applications, where a true-to-life listening experience is essential.

Many Fostex dome tweeters also incorporate innovative features, such as waveguides or acoustic lenses, to further enhance their performance. These additions help to improve soundstage and detail, allowing listeners to appreciate the nuances of their audio content fully.

Overall, the Fostex dome tweeter stands out for its combination of advanced materials, engineering excellence, and superb sound quality. Whether used in DIY speaker projects, professional studio monitors, or home audio systems, these tweeters provide an exceptional listening experience that truly captures the essence of high-frequency audio.
