CSS LD25X-WG Dome Tweeter

The CSS LD25X-WG Dome Tweeter with Waveguide is a meticulously engineered high-frequency driver designed to deliver smooth, extended treble response for discerning audio enthusiasts and loudspeaker designers. This tweeter excels in both two-way and multi-way speaker systems, where its integrated waveguide ensures seamless integration with midrange drivers, providing a coherent soundstage and precise imaging. It is particularly well-suited for high-fidelity home audio, studio monitors, and custom DIY speaker projects where controlled dispersion and low distortion are paramount.

At the heart of the LD25X-WG lies a 25 mm silk dome diaphragm, chosen for its natural, non-resonant character and ability to reproduce delicate high frequencies with clarity. The integrated waveguide not only enhances off-axis response but also lowers the resonance frequency to 865 Hz, allowing for a lower crossover point. With an impedance of 8 ohms and a sensitivity of 89 dB (1m/2.83V), this tweeter is efficient and easy to drive. The DC resistance (Re) is 6.4 ohms, while the voice coil inductance (Le) is a low 0.066 mH, contributing to extended high-frequency extension. The total Q factor (Qts) of 1.28, derived from a mechanical Q (Qms) of 4.21 and an electromagnetic Q (Qes) of 1.85, indicates a well-damped, controlled response. This combination of technical features ensures accurate, fatigue-free listening, making the LD25X-WG a superb choice for high-performance audio designs.
