The Z series is DD Audio's flagship series, made possible by DD Audio's experience in designing and manufacturing top-class subwoofers. The latest innovations in technology and materials combined with meticulous hand-crafted assembly work. The result is a completely different subwoofer with a performance that is completely different from what we have been used to so far. In the magnet structure, the Neodymium rods are symmetrically positioned vertically around the voice coil. This reduces the stray flux and increases the magnetic force on the voice coil. In addition, the open magnet structure enables really efficient voice coil cooling. DD Audio does not provide any numerical power rating for the element. The power rating is still sufficient for most needs. One Z series element has already exceeded 180 dB in dB Drag Race competitions several times. You can also get this element:•with a different colored cone•with a different colored dust cup•with 0. 25 ohm coils•with 0. 5 ohm coils•with 0. With 75 ohm coils•1.
