The MB12N405 is a hypervented neo mid-bass design with a linear frequency response and very high efficiency.Nominal Diameter: 300 / 12 mm/inch
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.
