Frequently Asked Questions about ASS-15


What performance does the ASS-15 Subwoofer from Audio System Italy offer?

The ASS-15 Subwoofer from Audio System Italy offers an impressive performance of 1000W RMS. This high RMS power allows the subwoofer to deliver powerful bass reproduction that is both deep and precise. The subwoofer is designed for enthusiasts who value powerful sound experiences. This performance can be combined with technical specifications such as Fo: 33.74 Hz, which also contributes to achieving stunning audio quality. The combination of a large voice coil diameter of 75 mm and a magnet diameter of 175 mm also contributes to this exceptional performance.

How are the sound characteristics of the ASS-15 Subwoofer influenced?

The sound characteristics of the ASS-15 Subwoofer are strongly influenced by its technical design. The subwoofer has a QMS of 8.756, indicating a high mechanical quality factor typical for resonance spectra. In conjunction with a QES of 0.825 and a QTS of 0.754, it is clear that this subwoofer is optimized for precise bass reproduction. These parameters, along with a paper cone and a carbon dust cap, drastically improve sound quality. Additionally, the careful construction with a ventilated air gap and a pole core bore optimizes heat dissipation, ensuring sound purity.

What are the dimensions of the ASS-15 and how does it fit in my car?

The ASS-15 Subwoofer has a mounting depth of 188 mm and an outer diameter of 390 mm. These dimensions are important when considering integrating it into your vehicle. Whether it fits in your car depends on the available space in the vehicle. Since the subwoofer has an ED of 346 mm, installation in some vehicles can be a challenge. Therefore, it is advisable to measure the installation space carefully before purchasing, especially in smaller trunks or in vehicles with specific installation requirements, to ensure optimal positioning.

What do the aluminum die-cast basket and the paper cone do in the ASS-15?

The aluminum die-cast basket and the paper diaphragm play crucial roles in the sound quality of the ASS-15 Subwoofer. The aluminum die-cast basket provides a stable and distortion-free environment, which is essential for achieving clear sound. It also has the advantage of minimizing vibrations due to its robustness. The paper diaphragm, on the other hand, is known for its ability to deliver sound detail fidelity. This combination of technologies ensures that the subwoofer produces clean and precise bass even at high volumes, ideal for music lovers seeking maximum sound performance.

What Thiele-Small parameters does the ASS-15 have and what do they mean?

The ASS-15 Subwoofer features specific Thiele-Small parameters that are critical for its performance. The QMS value of 8.756 represents the mechanical damping, which regulates vibrations. With a QES of 0.825, describing the electrical damping, and a QTS of 0.754, there is an excellent balance indicating a well-tuned subwoofer. The VAS value of 71.53L indicates the compliance of the diaphragm in an air spring, which affects the cabinet construction. These parameters are important if you want to ensure that the subwoofer achieves the best possible sound.

How does the Xmax of +/-15mm affect bass reproduction?

The Xmax value of +/-15mm in the ASS-15 Subwoofer plays a significant role in bass reproduction. This value indicates the maximum linear excursion of the diaphragm, meaning how far it can move in both directions to produce undistorted sound. A larger Xmax allows for deeper and cleaner bass reproduction, especially at high volumes. This is crucial for music genres that require deep, powerful bass, as it results in less distortion and overdriven tones. The generous excursion is thus a strength of the subwoofer in delivering exceptional bass lines.

What is the significance of the dual centering of the ASS-15?

The dual centering of the ASS-15 Subwoofer primarily aims to improve the mechanical stability and accuracy of the diaphragm movement. This technology ensures that the diaphragm remains controlled even at extreme volumes and that no lateral deviations occur. This means that the risks of distortion at high power output are reduced. This is particularly important for ensuring consistent, high-quality sound and extending the lifespan of the subwoofer. Therefore, the dual centering significantly contributes to the acoustic and mechanical performance of the subwoofer.

How does the SPL of 87.1 dB 1W/m affect the volume?

The SPL value of 87.1 dB 1W/m for the ASS-15 Subwoofer indicates the sound pressure level produced with 1 watt of power at a distance of one meter. This value is crucial for determining the efficiency of the subwoofer. Although it is not among the highest values in its category, it still shows that the subwoofer is capable of producing loud and clear audio outputs at moderate power. Especially if you enjoy listening to music at high volumes, a solid SPL value is important to ensure that there is little to no sound distortion even at higher levels. Thus, the subwoofer offers considerable performance with good efficiency.

What role does the stitched surround play in the ASS-15?

The stitched surround in the ASS-15 Subwoofer significantly contributes to durability and sound quality. A stitched surround increases the structural integrity of the diaphragm movement by ensuring that the surround remains firmly attached to the diaphragm and transmits sound cleanly. This is particularly important in subwoofers with high power, where strong diaphragm movements occur. Additionally, a well-constructed surround reduces the likelihood of unwanted noises that could impair sound quality. Thus, the surround helps ensure precise and stable sound reproduction, which is essential for demanding audio applications.

How does the pole core vent support the performance of the ASS-15?

The pole core vent of the ASS-15 Subwoofer is an essential aspect of the design to optimize performance. This vent helps dissipate the heat generated during operation more effectively, which enhances the performance and lifespan of the subwoofer. During intense use, the subwoofer can overheat, leading to distortion or damage. Thanks to the ventilation provided by the pole core vent, the temperature remains under control, even during heavy use. This is particularly advantageous when you use the subwoofer in an extremely demanding acoustic environment where it remains operational for extended periods.
