The linear displacement allows for undistorted playback of the bass, especially at high volumes. The robust construction ensures that the subwoofer operates without sound loss and distortions, even under maximum load.
The cone material used in the Audison Prima APS 10 S4S, which consists of water-repellent treated, pressed paper, has significant influences on the sound character. This design offers an ideal balance between stiffness and damping, enabling precise and dynamic bass reproduction. Thanks to the water-repellent properties, performance remains consistent even under humid conditions. The specific cone geometry, which was simulated using FEM and tested with the Klippel Scan Vibrometer, ensures improved displacement and sound quality.

Audison Prima APS 10 S4S: The high-density flux ferrite magnet technology

At the core of the Prima APS 10 S4S is a high-density flux ferrite magnet, providing exceptional magnetic density. This technology ensures precise and powerful sound reproduction, especially at high volumes. Unlike lower-density materials, ferrite offers improved energy efficiency, reducing stress on the voice coil and extending its lifespan. This optimization takes the performance of this subwoofer to a new level, enabling the reproduction of even the lowest frequencies with brilliant clarity.

Perfect impedance for high flexibility: 4 Ohm voice coil

The single 4-ohm voice coil of the APS 10 S4S represents an optimal solution for combination with modern amplifier systems. This impedance allows for either single configurations or, by paralleling multiple subwoofers, lower ecumenical resistance values. The design allows for maximum power output from the amplifier without interference or performance degradation. Lower impedances could lead to increased power consumption, while higher values ​​could reduce flexibility and efficiency.

The mechanics in detail: Xmax of 12.6 mm for precise bass reproduction

A standout feature of the Audison Prima APS 10 S4S is its 12.6 mm excursion (Xmax), which ensures both high precision and powerful bass reproduction. This excursion allows the subwoofer to reproduce low frequencies with great volume and minimal distortion. While larger Xmax values ​​would result in impressive bass, this could also overtax the mechanical capacity, while a smaller excursion would limit the ability to deliver bass intensity.

Electro-acoustic subtleties: Fs of 28.5 Hz for lowest frequencies

With a resonant frequency (Fs) of 28.5 Hz, the Prima APS 10 S4S subwoofer can reproduce the deepest bass frequencies necessary for an optimal driving experience. This low resonant frequency is achieved through the carefully tuned interaction of all acoustic and mechanical components. A lower Fs would penetrate deeper into the subsonic range, which is unnecessary in most automobiles, while a higher Fs could unnecessarily limit the audible bass range.

Installation rate Material specialty: Water-repellent pressed paper cone

Another unique feature of the Prima APS 10 S4S is the water-repellent paper cone. This construction protects the woofer from moisture and increases its durability under various environmental conditions. Compared to polypropylene or aluminum, paper is easy to form in car hi-fi applications and offers high rigidity and low weight. These properties lead to more efficient sound production with short response times, which is particularly advantageous for high-performance music.

Engineering in geometry: Specially developed cone-dust cap-basscle geometry

The specially designed cone-dust cap-bass geometry of the APS 10 S4S maximizes linear excursion with minimal installation depth. These design features determine the diaphragm's behavior at high volumes, reproducing harmonic sound waves even under extreme conditions. This optimization is an excellent example of the application of finite element modeling (FEM), which is used in the manufacture of automotive loudspeakers.

Precise listening experience: BL of 12.9 T•m ensures high efficiency

Particular attention is also paid to the force factor (BL) of 12.9 T•m, which describes the efficiency of energy conversion. High BL values ​​indicate a strong magnetic force field of the voice coil and result in powerful reproduction without any loss of power. This means that the APS 10 S4S is more efficient than models with lower values, which directly translates into dynamic and impressive bass fidelity.

Compact dimensions for easy installation: Only 120 mm installation depth

The ultra-flat design of these subwoofers allows them to be installed even in discreet enclosures without wasting space, as if a bulky subwoofer could waste space. The minimal space requirement of 120 mm allows for innovative installation concepts, making the APS 10 S4S ideal for vehicles with limited space, while still providing sufficient air volume for the cone movement. Incidentally, a larger installation distance could impair the efficiency of the cone due to resistance, but thanks to this design, this is not the case with the APS, unlike less flat speaker systems.

High-quality accessories: steel grille and plastic seal included

With the purchase of the Audison Prima APS 10 S4S, you receive not only the subwoofer itself, but also a high-quality, custom-fit steel grille and plastic gasket. These accessories protect the subwoofer both mechanically and aesthetically, ensuring that no external influences impair sound quality or operation. These custom-made accessories reduce the risk of damage and make the overall system more compatible for daily use in the vehicle.

Connection optimization: Single voice coil for AP F8.9 bit amplifier

The subwoofer is specially optimized for operation with an AP F8.9-bit amplifier. This combination allows for the full functionality of the integrated DSP. The bass signal feed via the bass boost function and the parametric equalizer make it an ideal partner for the APS 10 S4S subwoofer, guaranteeing a precise and powerful sound performance that doesn't lose any dimension even at maximum power.
