The MB15N407 is a ultra lightweight , shallow design, 15" neodymium mid-bass driver. The vented 4" voice coil design and the minimum weight make the MB15N407 a unique product in his category. The new hyper-vented aluminium basket and magnetic assembly design provide an excellent heat dissipation and lower power compression. Special air-forced ventilations are provided for voice coil, magnet assembly and basket. A large neodymium magnet disc powers the magnetic structure providing an extremely high flux density in the gap.
