SB Acoustics SB19ST-C000-4 3/4" Dome Tweeter

The SB19ST-C000-4 Dome Tweeter from SB Acoustics delivers exceptionally clear and detailed high-frequency reproduction, making it an ideal choice for audiophiles and DIY speaker builders seeking refined treble performance. This 19mm dome tweeter excels in two-way bookshelf speakers, compact monitors, and multi-driver systems where precise, airy highs are essential. Its low resonance frequency and controlled damping characteristics allow seamless integration with midrange drivers, ensuring a natural and cohesive soundstage across a wide listening area.

Engineered with a 4-ohm impedance and a sensitivity of 88.5 dB (1m/2.83V), this tweeter offers efficient power handling while maintaining low distortion. The total Q factor of 1.22, combined with a mechanical Q of 6.45 and an electrical Q of 1.5, provides a well-balanced transient response and smooth roll-off characteristics. The voice coil inductance is a mere 0.07 mH, contributing to extended high-frequency extension and minimal phase shift. With a DC resistance of 3.4 ohms and a resonance frequency of just 98 Hz, the SB19ST-C000-4 is capable of crossing over at relatively low frequencies, offering flexibility in system design.

Whether you are upgrading existing speakers or building a new high-fidelity system, this dome tweeter delivers the clarity and detail required for accurate sound reproduction.
