SB Acoustics SB21SDC-C000-4 Ring Dome Tweeter

The SB21SDC-C000-4 Ring Dome Tweeter from SB Acoustics delivers an exceptionally clear and extended high-frequency response, making it an outstanding choice for audiophile-grade loudspeaker designs. Engineered for precision, this tweeter ensures that every detail in the upper register is reproduced with remarkable accuracy and airiness.

Ideal for use in two-way bookshelf speakers, three-way systems, or high-end studio monitors, this ring dome tweeter integrates seamlessly with midrange drivers thanks to its low resonance frequency of just 72 Hz. This characteristic allows for a smoother crossover transition and a more coherent soundstage, whether you are building custom loudspeakers or upgrading existing designs.

Technically, the tweeter features a 20mm ring dome diaphragm with an impedance of 4 ohms and a sensitivity of 91 dB (SPL 1m/2.83V), ensuring efficient power handling and dynamic output. The voice coil inductance is a mere 0.04 mH, contributing to excellent high-frequency extension, while the total Q factor of 0.95 and DC resistance of 3.1 ohms reflect careful engineering for controlled damping. With a compact mounting depth of 31.5 mm and an overall diameter of 91.9 mm, this tweeter is straightforward to integrate into a variety of enclosures.

Combining advanced materials with meticulous design, the SB21SDC-C000-4 offers a refined solution for achieving pristine high-frequency reproduction in your next project.
