MIDRANGEMR10N301Professional Low Frequency TransducerPART NUMBER 11100005Features3-inch Inside/outside voice coil, high BL neodymiumdesignVery high sensitivity (109 dB/1w in horn loadedapplication), very high BL factor700 Watt Continuous program power handlingThe MR10N301 is a high efficiency, high power midrange specially designed toprovide superior sound pressure level in a very compact size. The total weight isreduced to less than half of a comparable ceramic midrange thanks to an incrediblypowerful neodymium magnet assembly. The unique sealed basket design doesn’trequire a back sealing chamber, simplifying the cabinet design and improving heatdissipation. Every detail of this speaker has been optimized to offer the bestresponse and perfect control to the midrange frequencies.ApplicationsThe MR10N301 is especially designed for horn-loading and line array configurations.The ideal range of application are mid and mid-low frequencies.The combination of the 3” voice coil, the neodymium motor and the heat sinkbasket design makes this driver the ideal solution for the most demandingapplications.Frequency range: 150 Hz - 2 kHz (mid and mid-lowfrequencies)Unique aluminum sealed basket featuring ventedfin heat dissipation designCalibrated back volume for a perfect time domaintransient reproductionPHASE PLUGpart number 1336005115020001420 100 1.000 10.000 20.000
