Mid-bass 12", 400W AES, 800W Program |  |
|
|
|
Very high sensitivity, excellent linearity and very low distortion.
Voice coil construction, suspensions and cone materials designed to survive at 400 Watt RMS power.
Applications
A very light moving mass, a curve response linear above 3 kHz makes the MB12G301 a very good solution for high quality two or three way system. The aluminum voice coil guarantee a very high efficiency in conjunction to a proper Q factor for a good bass response. |
