CSS T22-04 Dome Tweeter

The CSS T22-04 Dome Tweeter is a precision-engineered high-frequency driver designed to bring clarity and airiness to any loudspeaker project. Whether you are building a dedicated two-way bookshelf speaker, upgrading an existing multi-way system, or crafting a high-end home cinema setup, this tweeter delivers an extended and detailed top end that complements a wide range of midrange and bass drivers. Its 4-ohm impedance makes it particularly suitable for modern amplifier designs, ensuring efficient power transfer and consistent performance across the frequency spectrum.

From a technical standpoint, the T22-04 boasts a resonance frequency of 1099 Hz, which allows for a relatively low crossover point and seamless integration with midrange units. The sensitivity of 87.7 dB (measured at 1 metre with 2.83 V) provides a balanced output that works well in both modest and high-power systems. The driver’s electrical Q (Qes) of 3.15 and mechanical Q (Qms) of 9.3 combine to give a total Q (Qts) of 2.35, indicating a well-damped, controlled response that minimises unwanted ringing. With a DC resistance of 3.7 ohms, this tweeter is built for reliable, long-term operation. For audio enthusiasts seeking a refined, extended high-frequency performance, the CSS T22-04 Dome Tweeter is a superb choice that will elevate your next build.
