RCF MB12N405 12 in. Woofer with Hypervented Neo Mid-Bass Design

To get this performance the magnetic structure use a high flux neo disc and the cone assembly a fibre loaded exponential shape along with a high excursion triple roll. constant geometry surround.

The fibreglass former and aluminium voice coil provide a very high power handling maintaining a light mass and a proper Q factor for bass alignment.
