FT28D specifications

The Fostex FT28D is a high-performance tweeter that has gained recognition among audio enthusiasts and professionals alike for its exceptional sound reproduction and innovative design. Specifically engineered to deliver clear and detailed high-frequency response, the FT28D serves as an ideal component for high-fidelity loudspeaker systems, studio monitors, and home audio setups.

One of the standout features of the FT28D is its use of a diaphragm constructed from a unique blend of textile materials. This not only enhances the tweeter's ability to reproduce high frequencies with remarkable precision but also contributes to a smooth frequency response that minimizes harshness or distortion. The diaphragm design allows for extended frequency response up to 40 kHz, making it particularly suitable for high-resolution audio playback.

The FT28D also incorporates an innovative neodymium magnet system that provides strong magnetic flux and enables improved sensitivity. This powerful magnet helps to increase the efficiency of the tweeter, allowing it to produce louder sound levels without requiring excessive power. This is particularly advantageous for audio systems that prioritize dynamic range and clarity across a wide listening volume.

Another important characteristic of the FT28D is its rotatable waveguide. This feature allows for more versatile installations by enabling the user to adjust the dispersion pattern of the tweeter according to the acoustic environment. The waveguide helps to create a more focused soundstage, enhancing stereo imaging and providing a more immersive listening experience.

The build quality of the FT28D further enhances its appeal. Constructed with durable materials, this tweeter is designed to withstand the rigors of professional use while maintaining consistent performance. The mounting design is also user-friendly, allowing for easy integration into various speaker cabinets.

In summary, the Fostex FT28D tweeter is a standout choice for anyone looking to incorporate a high-quality high-frequency driver into their audio system. With its advanced diaphragm technology, powerful neodymium magnet system, adjustable waveguide, and robust construction, the FT28D promises to deliver exceptional sound clarity and performance. Whether for professional studio environments or home audiophile setups, this tweeter is sure to impress with its ability to faithfully reproduce the nuances of music and sound.
