RCF MB12N405 - 12" 1000W 8 Ohm
The MB12N405 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 MB12N405 is ideal where is required extremely high power handling, very high efficiency and perfect linearity
- Is the ideal 12" mid-bass woofer for reference high fidelity, high performance midbass application in compact 2 way system.
Features
- 4-inch, fibreglass inside/outside aluminium voice coil
- 2000W continuous program power handling
- 98.5 dB Sensitivity
- 50 Hz - 2 kHz Frequency range
- Dual-forced air ventilation for minimum power compression
- Triple roll surround and exponential cone geometry
