SB Acoustics SB26ADC-C000-4 Aluminum Dome Tweeter

The SB26ADC-C000-4 Dome Tweeter from SB Acoustics represents a refined choice for audiophiles and DIY enthusiasts seeking exceptional high-frequency reproduction. Engineered with precision, this 25.4mm dome tweeter delivers a clear, extended response that brings recordings to life with remarkable transparency and airiness. Whether you are upgrading a two-way bookshelf speaker, designing a dedicated high-end system, or restoring vintage cabinets, this tweeter integrates seamlessly into a wide range of audio projects, offering both versatility and performance.

At the heart of its design lies a voice coil inductance of just 0.04 mH, which minimises impedance rise at higher frequencies and ensures outstanding transient accuracy. This low inductance allows the tweeter to reproduce fine details and subtle harmonics with exceptional speed and precision. With a sensitivity of 90 dB (SPL 1m/2.83V) and a nominal impedance of 4 ohms, it pairs well with moderate amplification. The total Q factor of 1.2, combined with a resonance frequency of 68 Hz, indicates controlled behaviour near its lower limit, while the mechanical and electrical Q values of 2.9 and 2.0 respectively contribute to a balanced, natural sound. The DC resistance of 3.2 ohms further supports stable performance. Ideal for critical listening, this tweeter brings clarity and refinement to any loudspeaker design.
