SB Acoustics, SB23CACS45-8, 8″ Ceramic – Aluminum Cone Woofer 8 ohm
A very nice woofer from SB Acoustics that features a white Ceramic – Aluminum cone. The cone incorporates symmetrical ridges in the cone to further stiffen it. This moves the breakup mode out to where you can easily use this woofer in a two-way system.
The Ceramic coating is done by a plasma process. This gives the cone additional stiffness.
Take a look at the “Ceramicos” kit for a great example.
Like every other SB driver, this one features a rugged cast aluminum frame, large voice coil, and rubber surround.
