JBL’s patented Differential Drive® Technology ferrite drivers incorporate 3" voice coils with lower mass ferrite magnets for reduced weight, increased power handling, exceptionally low distortion and extended low frequency response. JBL’s 2432H is the only neodymium 3" voice coil compression driver in this class, delivering very high power levels and smooth, crystal clear sound.
