In early 2005, the first generation of the Z-Motor was launched. 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.

The Z4 series uses an impressive open neodymium motor with 18 lenses of grade N48, equipped with an even more powerful motor like its smaller siblings in the Z3 series. The Z4 series has the strongest neodymium drive in the world! It doesn't get any better!

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 design improvements over previous models. 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.

The free-flow cooling system was improved by installing pole vent slots 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 increased maximum excursion and a wider range of system configurations.

The striking look of the Z is characterized by a black oxide finish combined with red anodized accents. The motors are also decorated with custom CNC-engraved designs, and each motor is engraved with its production number, making each part unique.

You will notice that the standard Thiele-Small parameters for the Z series are missing. 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.

The Z series subwoofers also come equipped with the Evolution Subwoofer Package (ESP). Drivers equipped with ESP feature larger diameter 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.

The Z series comes standard with an oversized dust cap made of black composite in dry layup, 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 custom look and/or additional performance for a specific application.

ESP Subwoofer Features:

• Carbon Fiber Blend Cone (CFB) - The CFB composition uses an effective carbon fiber-based cocktail to provide you with the highest strength-to-weight ratio in the industry.
• Vario-Density Extended Range of Motion Surround (V-ROM) - Offers ultimate linear control at high excursion while enabling dynamically sounding bass reproduction. The control ribs are compressed to a lower density than the main surround body to allow a seamless control system. The harder you control it, the more control you get.
• Tuned Spider System (TSS) - Each suspension is tuned for specific performance characteristics, e.g., high definition, power handling, X-stiff control.
• Super-Frame (SFrame) - Maximizes spider diameter, cone diameter, suspension excursion, and thus acts as a secondary shorting ring, providing additional heat dissipation for better heat flow from the coil.
