The MB15N405 is a hypervented neo mid-bass design with a linear frequency response and very high efficiency. 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.
Applications:
The MB15N405 is ideal where is required extremely high power handling, very high efficiency and perfect linearity.
Is the ideal 15" mid-bass woofer for reference high fidelity, high performance midbass application in compact 2 way system.
