The MB12X301 is designed to provide an excellent frequency response linearity with very low distortion. A strong magnetic structure guarantee dynamic and precision. The new dual forced hyper-venting system guarantee a very efficient voice coil ventilation for minimum power compression and incredible power handling.
M-roll surround, exponential cone geometry and spider design offer great linearity and precise reproduction.
Features:
- 3-inch, fibreglass inside/outside copper voice coil
- 1000W continuous program power handling
- 98.0 dB Sensitivity
- 45 Hz – 2.5 kHz Frequency range
- Hypervented for minimum power
- compression M-roll surround and exponential cone geometry
Applications:
A light moving mass, a curve response linear above 2.5 kHz makes the MB12X301 a very good solution for high quality two way systems.
The 3.0" copper voice coil guarantee a very high power handling and perfect low frequency control.
