The well-designed SB26CDC-C000-4 tweeter not only matches the SB Acoustics Ceramic woofers aesthetically but also technically. Thanks to the low resonance frequency, linear response and high power handling, this tweeter is ideally suited for the more demanding speaker builds where other tweeters would be easily strained.
Highlights
- Phase optimized diaphragm design for coherent high frequency radiation
- Copper cap for reduced voice coil inductance and minimum phase shift
- Saturation controlled motor system for low distortion
- Non-reflective rear chamber with optimized damping for improved dynamics
- Flow optimized vented pole piece for optimum coupling to rear chamber
- CCAW voice coil for low moving mass
- Long life silver lead wires
- Low resonance frequency

SB Acoustics SB26CDC-C000-4 1’’ Aluminium/Ceramic Dome tweeter
The well-designed SB26CDC-C000-4 tweeter not only matches the SB Acoustics Ceramic woofers aesthetically but also technically.

Other than that, ceramic domes offer smoothness and harmonic richness unavailable from conventional paper cone material. Ceramic materials also offer significantly higher stiffness numbers and slightly better internal losses than typical metals such as titanium or aluminum. Compared to polymers, paper, and other soft materials, ceramics provide: significantly higher stiffness to weight ratio, more consistent performance over a wide range of temperature and humidity as well as superior immunity to UV light and sunlight, to water and salt water and to combustibility.
