It forever changed the way people thought about a high-performance subwoofer and pushed the boundaries of car hi-fi to new extremes. Over the years, many versions of the Z-motor have been produced, and this spirit of experimentation has driven DD to constant improvement and innovation.\u003c\/p\u003e\n\u003cp\u003eThe Z3 series uses an impressive open neodymium motor with 13 lenses of N48 grade, just like their bigger brothers in the Z4 series. The steel motor parts from the USA are machined in DD Audio's hometown OKC, and all moving parts are made in the USA from the best available materials and manufacturing methods. The current Z models feature several structural improvements over earlier versions. DD was able to overcome structural saturation limits and increase peak and total flux levels by channeling more energy through our magnet lens architecture via more efficient flux paths, tighter lens alignment, and converging flux lines.\u003c\/p\u003e\n\u003cp\u003eThe free-flow cooling system was improved by adding longitudinal pole vents to increase airflow to the voice coil former. Then DD increased the thermal mass and applied heat-absorbing coatings in target areas to support long-term heat dissipation. Additionally, DD made geometric changes that allow for increased maximum excursion and a wider range of system configurations.\u003c\/p\u003e\n\u003cp\u003eThe striking look of the Z is characterized by a black oxide finish combined with red anodized accents. The motors are also adorned with custom CNC-engraved designs, and each motor is engraved with its production number, making every part one of a kind. You will notice that the standard Thiele-Small parameters are missing for the Z series. This omission is intentional, as each Z is custom-built, allowing for zillions of possible parameter sets, making a static set of specifications very prone to inaccuracies.\u003c\/p\u003e\n\u003cp\u003eThe Z series subwoofers also come equipped with the Evolution Subwoofer Package (ESP). Drivers equipped with ESP feature larger diameter suspensions and deeper frames than standard subwoofers, as well as exclusive surround and cone designs. ESP subwoofers are truly built to maximize performance in their respective size class.\u003c\/p\u003e\n\u003cp\u003eThe Z series comes standard with an oversized dust cap made of black composite in dry construction, a red logo, and a treated paper cone, but can optionally be equipped with a custom suspension configuration, alternative composite dust caps, composite cones, powder-coated baskets, and a variety of logo options to give your subwoofer a personalized look and\/or additional performance for a specific application.\u003c\/p\u003e\n\u003cdiv style=\"border: 1px solid #e5e5e5; border-radius: 8px; padding: 20px; margin: 20px 0; background: #fafafa;\"\u003e\n\u003ch2 style=\"color: #232323;\"\u003eDD Audio Custom Subwoofers – Design your own!\u003c\/h2\u003e\n\u003cp\u003eOur \u003cstrong\u003eDD Audio Custom Subwoofers\u003c\/strong\u003e are not only an audio highlight – they are built exactly to your wishes!
