CSS LD25X Dome Tweeter

The CSS LD25X Dome Tweeter represents a refined approach to high-frequency reproduction, engineered to deliver clarity and precision in a variety of loudspeaker designs. This soft dome tweeter is an excellent choice for audiophiles and DIY enthusiasts seeking to upgrade existing systems or build new projects where accurate treble response is paramount. Its performance characteristics make it particularly suited to two-way bookshelf speakers, compact monitors, and multi-way designs requiring a dedicated high-frequency driver that integrates seamlessly with midrange units.

At the heart of the LD25X lies a 25.4 mm soft dome diaphragm, carefully selected for its ability to produce smooth, detailed highs without harshness. The tweeter operates with an impedance of 8 ohms and a sensitivity of 90 dB SPL at 1 metre with 2.83 V input, ensuring efficient power handling and compatibility with a wide range of amplifiers. Technical specifications reveal a resonance frequency of 865 Hz, with a total Q factor (Qts) of 1.28, derived from a mechanical Q (Qms) of 4.21 and an electromagnetic Q (Qes) of 1.85. The DC resistance measures 6.4 ohms, while the voice coil inductance is a low 0.07 mH, contributing to extended high-frequency response. With a cut-out diameter of 47.5 mm and a mounting depth of 31 mm, this tweeter is designed for straightforward integration into standard enclosures. The CSS LD25X Dome Tweeter delivers the refined top-end performance required for accurate, engaging sound reproduction.
