Spec Sheet PDF

Low Q, looks good for small vented box. These ceramic cones have a very nice, smooth upper midrange quality. Good upper midrange for 2way with low Fs tweeter.

SB Ceramic cones consist of an aluminum/ceramic dual layer cone. Ceramic provides a very hard and robust surface with improved sonic properties and cosmetic appearance.

Vented cast aluminum chassis for optimum strength and low compression
Geometrically reinforced ceramic cone for optimum piston operation and reduced
break-up
Soft low damping rubber surround for improved transient response
Non-conducting fibre glass voice coil former for minimum damping
Extended copper sleeve on pole piece for low inductance and low distortion
CCAW voice coil for reduced moving mass
Long life silver lead wires
Vented pole piece for reduced compression

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

Amazing extended response with distortion low distortion. It requires high order crossover, but it is perfect when paired with the ceramic tweeter in a 2 way system.
