The Z-series is DD Audio’s flagship series, made possible by DD Audio’s experience in designing and manufacturing high-end subwoofers. The latest innovations in technology and materials combined with precise hand-made assembly work. The result is a completely different subwoofer whose performance is completely different from what you have been used to until now. In the magnet structure, the Neodymium rods are in a symmetrical vertical position around the voice coil. In this way, the stray flux is reduced and the magnetic force on the voice coil is increased. In addition, the open magnet structure enables really effective cooling of the voice coil. DD Audio does not indicate any number for the element for power duration. The power duration is still sufficient for most needs. One element of the Z series has already exceeded 180 dB in dB Drag Race competitions more than once.
