DJ 12 MB300

MID-BASS

High efficiency 12″ mid-bass.

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 DJ 12MB300 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.
