Overview4-inch, fiberglass inside/outside copper voice coil 2200W continuous program power handling 100 dB Sensitivity 45 Hz – 2.5 kHz Frequency range Dual-forced air ventilation for minimum power compression Triple roll surround and exponential cone geometry Specifications
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.
