ESP equipped drivers sport larger diameter suspensions and deeper frames than standard subs and exclusive surround and cone designs. ESP subs are truly built to maximize performance in their designated size class. By increasing the surface area of the voice coil, size of the magnetic gap, and its heat dissipating abilities, the Z4 is able to be driven just as hard as the Z3, but with increased long-term high power handling. The USA steel motor parts are machined in DD Audio’s hometown of OKC, and all the moving parts are USA made from the finest materials and manufacturing methods available. The Z series is DD Audio’s highest performing subwoofer line, designed specifically for precision, with competition in mind. Using the strongest motor on the planet, the Z series has won every major Sound Quality and Sound Pressure Level contest, in every variant, all over the world.

The Z4 is for pros who know how to take advantage of the higher energy and improved handling. Everything but the frame has been upgraded to further eliminate loss of energy, better manage magnetic field distortion, and improve stress handling. Originally coined The Beast, the 9900s first appeared on the market in the early 2000s.
Signal Processors
HiDef Tuned are great for systems where fidelity inside the car is the main focus. These subs trade a small amount of power handling and output capability, compared to the Power Tuned, for the ability to work better in small ported and sealed enclosures and extract the most efficiency from a given amplifier power. We hyper analyze details like flux density, voice coil travel, and thermal dissipation in our motors so we can customize our designs to maximize the performance of the circuits that drive the moving parts. The 3500 series woofers also come equipped with DD Audio’s Evolution Subwoofer Package (ESP).
Sealed Enclosures
The ESP-equipped subwoofer has a larger suspension diameter than a standard woofer, as well as a deeper basket and specially optimized surrounds for greater excursion and enhanced reliability. This is where all that stuff about the best designs and best parts really comes into play. The main goal of any subwoofer design is to pass through the original signal as true as possible. A speaker is taking an electrical signal and transferring this electrical energy to a vibration in the air. In the process we have a convoluted exchange involving electrical induced magnetic waves interacting with permanent magnetic waves inducing motion passing through rigid mechanical parts suspended by flexible parts passing wave energy to the air.

Choosing a sealed enclosure is also a great way to go when it comes to confined cargo areas and limited cost for construction. We believe in supporting brick and mortar dealers and have carefully partnered with small businesses who can provide quality installation and customer satisfaction befitting DD AUDIO® equipment. It’s a favorite among enclosure builders and installers for its performance and versatility. It’s enjoyed daily by drivers who love their music and have a tendency to get over enthusiastic with the bass knob. It’s also a testament to DD AUDIO’s quest for performance, devotion to USA Made build quality, and commitment to the ever evolving audio engineering process that comes with the modernization of materials and tooling.

It took a brief hiatus, but now it’s back and more beastly than ever. The latest iteration was developed in response to the recent explosion in ultra-low-frequency music. These subwoofers were designed to provide long-term power handling, with accuracy, and high excursion capabilities. It’s been optimized for a 1500 – 2500 watt power band with the ability able to handle bursts of up to 10,000 watts. It boasts 3 inches of magnet cross-section, over a 10″ OD, and weighs in at 70 pounds (motor only). The traditionally tight DD magnet gap drives a 4″ flat wound aluminum voice coil to a peak excursion in excess of 3 inches while keeping enough turns in the gap to maintain power and control.

LOADED ENCLOSURES
We take pride in using the best designs and the best parts to make the best subwoofers on earth. We do not make compromises to profit from substandard equipment; no expense is spared when creating our products thus ensuring maximum product performance and longevity. The Power Tuned woofers are constructed with additional mechanical and electrical damping to handle the daily rigors of any bass enthusiast. DD Audio’s 3500 series woofers are some of the most sonically accurate woofers the company sells. Thanks to a low moving mass design, high energy, and well-focused magnetics, these woofers provide accurate reproduction of any bass note, regardless of how loud you want to play it. When the goal is to "Make Better Music" or "Make Better Content," you need an incredible workflow alongside pro audio studio equipment, podcasting, and pro video equipment.

In the supplied vented enclosure, the performance of the 3510-ESP certainly did not disappoint. The very bottom of the audible register was very low, allowing me to easily hear the very subdued kick drum in Livingston Taylor’s Grandma’s Hands. This is a listening test I perform frequently, as a good many woofers do not reproduce these extremely low frequencies at audible levels. Dire Straits’ Heavy Fuel and Marc Cohen’s Walking in Memphis were excellent, with tight transients and correct timbre. Most sealed enclosures are best for sound quality and limited space applications. The subwoofer, depending on specific variables, may tend to play much tighter and more accurately then a typical vented enclosure.
The New Z4 Subwoofer Is The Most Powerful Z That DD Audio Has Ever Made
Due to its open motor structure, the Z series experiences an increased benefit from cooling channels machined into the pole piece, resulting in a higher volume of airflow redirected to the voice coil. The pillars surrounding the pole have been extended to allow for increased excursion and longer coil windings. The magnetic configuration changed slightly to make use of the very high iron content steel to increase the flux energy that crosses the gap. The 1100 Series subs are designed to be highly efficient and sound amazing. Like all of DD Audio’s made in USA subwoofers they use the highest grade parts on the planet and can be personalized with custom build options.
To further compliment the Z’s striking motor cosmetics the aluminum quick-change top plate, and shorting ring both feature red anodized accents. You’ll notice the standard TS parameters are missing for the Z subs. This omission is on purpose because each Z is custom built to order allowing for Zillions of possible parameter sets making one static set of specs very prone to inaccuracy. The reason we build Zs custom to order is it gives a system designer the utmost freedom to design for their specific application. The Z Series subs also feature our Evolution Subwoofer Package (ESP).
Entertaining minds will revel in the endless system design possibilities deliverable with these precision low-frequency devices. We take pride in our subwoofer engineering achievements, contest records and accolades, but we will never consider our quest complete. We continuously analyze listening trends, user habits, and new technologies so we can make any necessary tweaks along the way. This is all so at the end of the day we can, without a doubt, say we’re proud to build the best subwoofers on the planet. All of this technology drives a cone made from a combination of pulp and carbon fiber, which is also supported by a special V-ROM design foam surround. The surround is built with the same profile as DD Audio’s Extended Range of Motion (EROM) surrounds, but with flex ribs that allow it to retain its strength and shape even at the extremes of excursion.
Our sample is the 3510-ESP, a 10-inch subwoofer built on a rugged cast aluminum basket and powered by a huge triple-stacked 170-mm motor. The woofer tips the scales at right around 37 pounds, so you know this is a serious 10-inch driver as soon as you pick it up! The 3510’s magnetic energy is focused around a pair of three-inch, four-layer copper voice coils. The coils are coated with an ultra-high-temperature capable varnish, and wound on a special former composed of several different materials. All of this engineering is designed to result in excellent heat transfer, and allow really high power handling without failures. Furthermore, the former is double-slit to reduce inductance, and there are vent holes placed above the coil windings to increase airflow and improve coil cooling.
