In early 2005, the first ever generation Z engine was launched. It forever changed the way people thought about a high performance subwoofer and pushed the boundaries of carhifi to new extremes. Many versions of the Z engine have been produced over the years, and this spirit of experimentation has driven DD to constant improvement and innovation.

The Z3 series uses an impressive open neodymium motor with 13 N48 grade lenses, just like their big brothers in the Z4 series.

The USA-made steel motor parts are machined in DD Audio's hometown of OKC, and all moving parts are made in the USA using the best materials and manufacturing methods available.

The current Z's feature several design improvements over earlier models. DD was able to overcome structural saturation levels and increase peak and total flux levels by allowing more energy to flow through our magnetic lens architecture via more efficient flux paths, tighter lens alignment and converging flux lines.

The free-flow cooling system has been improved by adding longitudinal pole valves to increase airflow to the coil former. Then DD increased the thermal mass and used heat-absorbing coatings in the target areas to aid in long-term heat dissipation.

DD has also made geometric changes that allow for increased maximum displacement and a wider range of system configurations.

The eye-catching look of the Z features 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 each part unique.

You'll notice that the standard TS parameters are missing for the Z Series. This omission is intentional, as each Z is made to order, allowing for zillions of possible parameter sets, making a static set of specs highly susceptible to inaccuracies.

The Z Series subwoofers also feature the Evolution Subwoofer Package (ESP). ESP-equipped drivers 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 classes.

The Z-Series comes standard with an oversized black composite drywall dust cap, red logo, and treated cellulose cone, but can be optioned with a custom suspension configuration, alternative composite dust caps, composite cones, powder-coated frames, and a variety of logo options to give your subwoofer a custom look and/or added performance for a specific application.
