Product Details

HiVi M8a 8" Aluminum / Magnesium Woofer

HiVi's M8a woofer has been designed to deliver outstanding bass reproduction in vented systems. The M8a utilizes a unique one-piece aluminum/magnesium composite cone. The cone's superior rigidity contributes to dynamic and accurate reproduction of transient program material. A high-temperature voice coil former, air transparent spider, and venting of the coil maximize power handling. The M8a provides excellent quality bass definition with good extension (40 Hz), and can be used to great effect in a medium sized 2-way speaker system or as a woofer in a 3-way system.
