The Audio-Technica AT150LMX Dual Moving Magnet Cartridge features a Gold evaporation tapered cantilever and ML (micro linear) broadband VM vibrating system of stylus. Its low magnetic loss para toroidal generation of electricity system of the laminating core matches to the high efficiency transmission of the PCOCC (monocrystal condition high purity oxygen free copper). The center sealed plate utilizes wide separation of the left and right independent magnet to the fullest. This is a unit with high power Neodymium magnet and C.C.A.W. voice coil for heavy bass and detailed treble.
