- 4-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
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.
