The Power Tuned Z310 ESP is an advanced 10-inch subwoofer from the renowned manufacturer DD Audio. Since the introduction of the first Z-Motor generation in 2005, this series has set revolutionary standards in the world of high-performance subwoofers by consistently redefining the limits of car audio. Key features of the Z310 ESP include its powerful neodymium magnet system, top-quality American craftsmanship, and a custom design complemented by red anodized accents on a black oxide layer. Innovative thinking and continuous improvement are at the core of this product—from structural enhancements to more efficient heat dissipation to geometric adjustments for maximum excursion and system versatility, the Z310 ESP is not only powerful but also forward-looking.

In early 2005, the very 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 audio 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 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 values and increase peak and total flux levels by allowing more energy to flow 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 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. The striking look of the Z is characterized by a black oxide layer 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 will notice that the standard Thiele-Small parameters for the Z series are missing. This omission is intentional, as each Z is custom-built, enabling zillions of possible parameter sets, making a static set of specifications very prone to inaccuracies.

The Z series subwoofers are also 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 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 frames, 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 offer you the highest strength-to-weight ratio in the industry.
• Vario-Density Extended Range of Motion Surround (V-ROM) - Provides 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 and provides additional heat dissipation for better heat flow from the coil.
