Spec Sheet PDF
These ceramic cones have a very nice, smooth upper midrange quality. Features include a vented cast aluminium chassis for optimum strength and low compression, soft low-damping rubber surround for improved transient response, and a shorting ring in the motor system for reduced distortion. 12cm Ceramic Cone Midbass, with 25mm Voice Coil.
Why Ceramic? Ceramic cones 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. For example, polypropylene's performance changes dramatically with temperature, while paper can be significantly affected by humidity.
- Superior immunity to UV light and sunlight.
- Superior immunity to water and salt water.
- Superior immunity to combustibility.
