In early 2005, the first ever generation of the Z-Motor was launched. It forever changed the way people thought about a high performance subwoofer and pushed the boundaries of carhifis to new extremes. Over the years, many versions of the Z-Motor have been produced, and this spirit of experimentation has driven DD to constantly improve and innovate.
The Z4 series uses an impressive open neodymium motor with 18 N48 grade lenses and is therefore equipped with an even more powerful motor than its little brothers in the Z3 series. The Z4 series has the most powerful neodymium motor in the world! It doesn't get any better than this!
The steel engine parts from the USA are machined in DD Audio's hometown of OKC, and all moving parts are made in the USA from the best materials and manufacturing methods available.
The current Z's feature several design improvements over previous 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 was improved by adding longitudinal pole valves to increase airflow to the coil former. DD then increased the thermal mass and applied heat-absorbing coatings in the target areas to aid long-term heat dissipation.
DD also made geometric changes that allow for increased maximum excursion and a wider range of system configurations.
The Z's eye-catching appearance is characterized by a black oxide coating 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 for the Z Series are missing. This omission is intentional, as each Z is made to order, allowing for zillions of possible parameter sets, making a static set of specifications highly susceptible to inaccuracies.
The Z Series subwoofers are also equipped with 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 class.
The Z-Series comes standard with an oversized black composite drywall dust cap, red logo and treated cellulose cone, but can be optionally equipped 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 additional performance for a specific application.
