AS-DV-X1051
Overview
The Esque Audio Audiography AS-DV-X1051 redefines performance by delivering massive output, tight dynamics, and exceptional sound clarity—all in perfect harmony. At the heart of this subwoofer is a combination of precision-engineered electromagnetic and mechanical design, built to handle extreme conditions while maintaining absolute control and fidelity.
One of its standout features is the single-piece forged motor structure, engineered for maximum strength and thermal stability. Finished with an ED (Electrophoretic Deposition) coating, the motor is highly resistant to corrosion and wear, ensuring long-term durability and consistent performance. This robust motor design is paired with an advanced suspension system and a lightweight pressed paper cone, offering a perfect blend of rigidity and natural damping for highly accurate bass reproduction.
This isn’t just about raw power—it’s about control, craftsmanship, and musicality. Every detail in the AS-DV-X1051 reflects Esque Audio’s commitment to delivering precision-engineered sound with soul.
The 10TXDV is designed to operate in either a 1.4 to 1.6 cu ft ported enclosure or a 1.25 cu ft sealed enclosure, with amplifier power in the 300W–500W range being the ideal range for operation. The “Specifications” tab has detailed enclosure suggestions.

POWER RANGE FOR ONE SUBWOOFER
Technology
COIL HEAT REDUCTION - CHR OPTIMIZED MOTOR
Esque Audio’s Coil Heat Reduction technology, a potent innovation created by our top engineers, lowers coil heat by controlling the temperature with ideal air pressure, extending the lifespan of our subwoofer beyond that of any other 10 inch subwoofer. As a result, distortion is greatly minimized and transients are authentically reproduced, or simply put, the bass is tight, clean, and articulate.
Cone
The cone used in this design is a high-quality pressed paper cone, chosen for its excellent balance of natural damping, rigidity, and lightweight performance. Pressing the fibers during manufacturing creates a denser, more uniform structure, which enhances cone stiffness while keeping mass low. This results in smooth, controlled movement and accurate sound reproduction, especially in the midbass and low-frequency ranges.
Why cone stiffness matters: As a woofer’s excursion and motor force increase, maintaining structural integrity becomes critical. A well-pressed paper cone resists deformation under high pressure, preventing the voice coil from shifting out of alignment. Misalignment can cause the coil to rub against the motor’s top plate and pole piece, leading to unwanted distortion. Thanks to its natural acoustic properties and engineered stiffness, the pressed paper cone minimizes this risk, delivering clean, detailed audio even at high output levels.
Due to the significant excursion, our engineering team concentrated on obtaining high levels of cone stiffness without adding a lot of bulk. In the end, this produced the greatest 10inch Sub-woofer design possible.
Motor to Frame-Frame to Motor, air cooling technique.
The Ported Frame Cooling system by Esque Audio circulates cold air through slots that are located immediately beneath the Subwoofer’s voice coil winding. By preserving the impedance of the subwoofer voice coil, this not only reduces heat but also improves sound quality.
Detailed Information:
Numerous speakers use venting strategies to improve voice coil cooling. Large holes normally found directly below the shelf for the spider attachment are used to do this. However, our experts have attached a motor to that frame, which circulates air through motor holes to a ported frame. This high-velocity air flow blows directly or aggressively on the voice coil even though it offers the optimum cooling effect.
This cooling method is enhanced by our design in a variety of ways. As there are three drillings below the motor from which the air flow is connected to three ports in the frame, this connects the motor to the frame. Between the bottom surfaces of the frame and the motor, a narrow, high-velocity air route is formed. Direct access to the voice coil is provided by this air channel, which subsequently ascends into the spider air chamber. Through this narrowed air route and the excursion action of the woofer, a significant amount of cold air is directed directly at the coil windings.
Another significant advantage is that, unlike in a traditional design where the upper surface of the pole piece is shielded from the air flow by the lower flange of the frame, the upper surface of the pole piece, one of the speaker’s hotter components, is directly exposed to cooling air flow. With no extra components, raised frame technology significantly improves thermal power management and lessens compression effects.
