Double-stitched EROM beads for maximum durability and control

The double-stitched EROM surrounds of the 112a-D4 subwoofer not only provide a robust structure but also contribute to precise cone movement. This construction allows for exceptional control over the sound, regardless of the subwoofer's operating volume. Compared to single-stitched surrounds, double stitching ensures a longer service life by reducing material stress. This ensures consistent performance, especially at high excursion, which is paramount in the car hi-fi world. A lighter construction would have increased the risk of distortion at extreme volumes.

Laminated double-layer spiders for superior vibration damping

Thanks to its laminated double-layer spiders, the DD Audio 112a-D4 offers superior vibration damping. This construction gives the subwoofer outstanding stability and prevents unwanted deformation under high pressure. Combined with other design elements such as the extended pole piece, it helps minimize deformation at high sound pressure levels, enabling precise bass reproduction. Comparable products often suffer from insufficient damping efficiency, especially in the lower frequency spectrum.

Non-pressed paper cone for natural sound characteristics

The non-pressed paper cone of the DD Audio 112a-D4 gives the subwoofer its typically soft, natural sound characteristics. Unlike alternative materials, paper ensures low self-resonance, allowing authentic bass reproduction, and minimizing sound distortion. For remarkably natural sound quality, developers often chose paper in this application, especially for reproducing the finest low-frequency nuances. A less conventional material choice would have increased the risk of higher harmonics dominating.

Baskets with cooling slots for heat dissipation and performance stability

Equipped with baskets featuring strategically placed cooling slots, the DD Audio 12 subwoofer maximizes heat dissipation. These slots play a vital role in keeping the coil components cool during intensive use. This allows for stable and consistent performance without the risk of overheating, which is especially important in sports or performance cars where long distances require high continuous power. Inadequate cooling would have increased the risk of interruption or degradation of the sound signal.

Coil gap ventilation and extended pole piece for cooling and precision performance

A sophisticated coil ventilation system increases the efficiency of the DD Audio 112a-D4 by improving the voice coil's cooling capacity. Combined with an extended pole piece, the design allows for greater control at high power and protects against thermal failure. This ensures consistent bass and precise reproduction even at maximum volumes. Without these ventilation options, distortion and sound degradation would be almost inevitable.

Performance: 250 watts RMS and 1950 watts peak power for impressive sound experience

With 250 watts RMS and 1950 watts peak power, the 112a-D4 demonstrates the power a subwoofer can deliver. RMS defines the continuous power capacity, while peak power indicates instantaneous loads. This design ensures that the subwoofer remains confident at various volume levels. For car installations that require a wide dynamic range of sound, a higher peak power is essential. Subwoofers with lower peak power may seem overwhelmed at high, sudden volumes, which can lead to sound degradation.

Impedance D4 for flexibility in system integration

The DD Audio 112a-D4 features a dual voice coil impedance of D4, allowing flexibility in adapting to various power amplifier configurations. D4 coils are excellent for parallel connection to maximize the power of a low-ohm mono amplifier. A lack of understanding of electrical compatibility could lead to problems such as overloading the amplifier outputs, but correct impedance cleverly avoids this.

Thiele-Small parameters analyzed: equivalent volume Vas and resonance frequency Fs of the DD Audio 112a-D4

The DD Audio 112a-D4 features a remarkable equivalent volume (VaS) of 64.14 liters and a resonance frequency (Fs) of 32 Hz. VaS significantly influences cabinet design, as higher values ​​indicate a larger cabinet. With an Fs of 32 Hz, the subwoofer delivers impressive bass reproduction, perfect for deep bass reproduction in well-tuned cabinets. Lower Fs values ​​offer more intense bass reproduction for bass enthusiasts seeking deep bass.

Further Thiele-Small parameters: Qms, Qes, Qts and their significance in the application area

With a Qms of 6.21, a Qes of 1.08, and a Qts of 0.92, the 112a-D4 demonstrates a precise balance between mechanical control and electrical efficiency. Such low Qts values ​​support applications in a variety of enclosure types, including sealed and ported enclosures. Increasing the Qts would optimize the subwoofer for a different cabinet type, but closed systems would be less efficient. These values ​​result in precise, powerful bass responses, regardless of the vehicle design. Large variations could result in suboptimal bass performance.

Xmax and BL: Recognizable by the moving mass and the power factor of the subwoofer

A maximum mechanical Xmax of 10 mm ensures that the DD Audio 112a-D4 delivers distortion-free performance under extreme loads. Combined with a BL of 14, this subwoofer demonstrates exceptional control of its cone movements. For the most realistic and deep bass, a higher BL value in watts is crucial. A lower BL would reduce the subwoofer's ability to handle strong magnetic field forces efficiently and precisely.

Dimensions and installation: Limited possibilities in mounting solutions

The 112a-D4's 310 mm frame OD and 279 mm mounting diameter make it flexible for installation, especially in typical vehicle front-end applications. With a mounting depth of just 129 mm, it adapts to a wide variety of installations. Deeper subwoofers often require more extensive modifications to vehicle components. Despite these compact dimensions, the DD Audio 112a-D4 still offers powerful performance in suitable applications. This subwoofer offers optimized performance for all car hi-fi enthusiasts.
