Press Release (edited)–OKLAHOMA CITY, OK — DD Audio announced the release of its Z4 subwoofer, the newest member of the Z series, DD Audio’s highest performing subwoofer line.
The Z4 uses an 18 lens grade 52 neodymium open motor design. So,18 blocks of neodymium make up the woofers’ total magnetic lens. Grade 52 refers to the grade of neodymium, 52 being the highest grade commercially available.
By increasing the surface area of the voice coil, size of the magnetic gap, and its heat dissipating abilities, the Z4 is able to be driven just as hard as the Z3, but with increased long-term high power handling. The USA steel motor parts are machined in DD Audio’s hometown of Oklahoma City, and all the moving parts are USA made.
“Using the strongest motor on the planet, the Z series has won every major Sound Quality and Sound Pressure Level contest, in every variant, all over the world. The Z4 is for pros who know how to take advantage of the higher energy and improved handling,” said DD Audio.
In the Z4, all but the frame has been upgraded to further eliminate loss of energy, better manage magnetic field distortion, and improve stress handling.
Like the Z3 and the MiniZ in the current lineup of Z subwoofers, the Z4 has an open motor structure so it benefits from cooling channels machined into the pole piece, resulting in a higher volume of airflow redirected to the voice coil. The pillars surrounding the pole have been extended to allow for increased excursion and longer coil windings. The magnetic configuration changed slightly to make use of the very high iron content steel to increase the flux energy that crosses the gap.
