RCF MB12G301 Tiefton Chassis

Very high sensitivity, excellent linearity and very low distortion.
Voice coil construction, suspensions and cone materials designed to survive at 400 Watt RMS power.

Features:

-3-inch, fiberglass inside/outside copper voice coil
-800W continuous program power handling
-98 dB Sensitivity
-50 Hz – 3 kHz Frequency range
-M-roll surround and exponential cone geometry

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.
