The MB10G251 is designed to provide an excellent frequency response linearity with very low distortion. A strong magnetic structure guarantee dynamic and precision. M-roll surround and spider design offer great linearity and precise reproduction.
Applications
A very light moving mass, a curve response linear above 3 kHz makes the MB10G251 a very good solution for high quality two way systems. The 2.5" aluminium voice coil guarantee a very high power handling and perfect low frequency control.
The aluminum voice coil guarantee a very high efficiency in conjunction to a proper Q factor for a good bass response.
