Discover the Power Tuned Z418 ESP from DD Audio. This 18" (46cm) subwoofer represents the culmination of years of development and refinement, starting with the first generation Z-Motor in 2005. Equipped with an impressive open neodymium motor, you'll enjoy high-performance sound that puts this unit at the top of its class. Many design improvements over previous models increase the performance and versatility of this 18" subwoofer, which impresses with its striking looks as much as its inner values. Unique features such as the Evolution Subwoofer Package (ESP), outstanding material quality and manufacturing expertise ensure that your Z418 ESP subwoofer is not only powerful, but also durable and individual.

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 using 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 installing longitudinal pole valves to increase airflow to the coil former. DD then increased the thermal mass and used heat-absorbing coatings in the target areas to aid long-term heat dissipation.
DD has also made geometric changes that allow for increased maximum deflection and a wider range of system configurations.
The eye-catching look of the Z is characterized by a black oxide coating 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 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 size class.
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, alternate 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.
ESP subwoofer features:
- Carbon Fiber Blend Cone (CFB) - The CFB composition uses a potent carbon fiber-based cocktail to give you the highest strength-to-weight ratio in the industry.
- Vario-Density Extended Range of Motion Surround (V-ROM) - Provides the ultimate in linear control at high excursion while enabling dynamic sounding bass response. The control ribs are compressed to a lower density than the main surround body to provide a continuously variable control system. The harder you drive it, the more control you get.
- Tuned Spider System (TSS) - Each suspension is tuned to specific performance characteristics, e.g. High Definition, Power Handling, X-Stiff Control.
- Super-Frame (SFrame) - Maximizes the spider diameter, cone diameter, suspension deflection and thus works as a secondary shorting ring and provides additional heat dissipation for better heat flow from the coil.
