HiVi M4N 4" Aluminum/Magnesium Midbass
A shielded magnet structure allows the HiVi M4N 4" full-range speaker to be incorporated easily into audio/video applications. The driver may be used in a small closed box as a midrange unit in a three-way system and the good extension (70 Hz) in a vented enclosure allows for use in a 2-way two-driver or MTM configured system. Stamped steel frame, magnesium/aluminum ally cone, optimized magnetic circuit, and high temperature CCAW voice coil.
