Frequently Asked Questions about ASS6


How does the neodymium magnet in the ASS6 improve sound quality?

The neodymium magnet in Audio System Italy's ASS6 significantly enhances sound quality due to its high density and strength, allowing for more efficient power transfer to the voice coil. This results in more precise movement of the carbon fiber diaphragm, delivering fine sound details and increased dynamics. Neodymium is more compact than conventional magnets, enabling powerful sound performance without unnecessary mass despite a net weight of 1.38 kg. Thus, the ASS6 is capable of reproducing a wider range of frequencies with an excellent efficiency of SPL 87 dB, allowing you to enjoy music in clear and pure form.

What advantages does the carbon fiber diaphragm material of the ASS6 offer?

The carbon fiber diaphragm material in Audio System Italy's ASS6 provides lightness while maintaining stability, minimizing distortion and enabling precise sound reproduction. The resin filling further enhances this stability, ensuring that the speaker remains distortion-free even at high volumes. This combination ensures that the resonance frequency of 68 Hz is utilized efficiently. Especially if you enjoy listening to music loudly, this material allows for clear audio output without losses, while optimally balancing the radiation mass load of 14.6 g and making the sound appear natural and spatial.

How does the DC resistance Re of 3.60 affect the sound of the ASS6?

A DC resistance (Re) of 3.60 Ohms in Audio System Italy's ASS6 allows for effective control of the voice coil, enhancing sound fidelity. This resistance level ensures stable performance across the entire frequency range from 60Hz to 4.5kHz. The Re value ensures that energy is distributed evenly, leading to consistent audio quality at various volume levels. This stable current control, along with the voice coil inductance of Le 0.25 mH, enables detailed sound reproduction without losses in dynamic music pieces, which is particularly beneficial in demanding audio applications.

What frequencies can the ASS6 speaker reproduce?

The Audio System Italy ASS6 is designed for a frequency range of 60Hz to 4.5kHz, making it ideal for reproducing midrange and low frequencies. The frequency roll-off is recommended up to a high pass of 4.5kHz to achieve optimal sound balance. The speaker follows the natural physiological perception of the human ear and can thus support a wide range of music genres. This is particularly beneficial for music lovers who prefer genres with pronounced mid and low frequencies while still wanting to maintain clear, distortion-free tones in their audio content.

What does the motor strength BI of 4.9 mean for the ASS6?

The motor strength BI of 4.9 in the Audio System Italy ASS6 describes the ability of the speaker motor to efficiently move the diaphragm, which improves the overall sensitivity and acoustic performance of the speaker. A higher motor strength means that the speaker is capable of transferring more power from the voice coil to the diaphragm, resulting in precise and powerful sound quality. This characteristic is crucial for the dynamic reproduction of audio content. Combined with the Qms of 6.64, it guarantees demanding playback, which is particularly advantageous for complex musical pieces and dynamic jumps within a song.

What are the dimensions for installing the ASS6?

The Audio System Italy ASS6 speaker has a size of 6.5 inches (16.5 cm) and a voice coil with a diameter of 25.5 mm, making it compatible with a variety of vehicle installation sizes, provided there is enough space. During installation, it is important to ensure that there is enough room for the maximum linear excursion of Xmax 6.2 mm to avoid collisions with the vehicle trim. Additionally, the cone area of 138.9 cm² should be considered to ensure optimal sound distribution. Paying attention to these dimensions guarantees a hassle-free integration into your audio system for perfect sound performance.

What role does the SPL efficiency of 87 dB play in sound reproduction?

An SPL efficiency of 87 dB in the Audio System Italy ASS6 speaker means that the speaker can produce a sound pressure of 87 decibels at a power input of 1 watt from a distance of 1 meter. This indicates that the speaker is capable of playing efficiently loud without requiring a large power input. Such efficiency is beneficial when you want to enjoy music in your vehicle or in a home audio system, as it requires less power consumption for high volume, thus providing a more efficient use of audio power. Combined with the overall impedance level of 4 Ohm, this is enhanced.

What Thiele-Small parameters are specified for the ASS6 speaker?

The Thiele-Small parameters for the Audio System Italy ASS6 are: Qms of 6.64, indicating the mechanical quality; Qts of 0.81 defines the overall quality of the system, ideal for various enclosure applications. The resonance frequency Fs is 68 Hz, indicating the lowest frequency for efficient sound production. The compliance volume Vas of 14.5 liters shows the amount of air that is in equilibrium at this Fs, while the Mms of 14.6 g and the maximum linear excursion Xmax of 6.2 mm define the potential measure of movement within the specified system. These parameters are crucial components that accurately specify performance and sound characteristics.

How does the RMS power of 200W affect the performance of the ASS6?

The RMS power of 200W in the Audio System Italy ASS6 allows the speaker to continuously handle this power, ensuring stable and reliable operation. This capability is particularly important for playing the full range of music dynamically and without sound distortion, even at high volumes. Along with the rated power/hi-pass of 150Hz and a robust construction, the ASS6 offers excellent audio quality and durability in various audio applications. For the listener, this means that even with intensive use, you can enjoy your music in high-quality sound without worrying about overdriving the speaker.

What advantages does the Konex centering device offer during playback?

The Konex centering device in the Audio System Italy ASS6 stabilizes the voice coil during sound reproduction, supporting the accuracy of the diaphragm movement and preventing distortion at high excursions. This device significantly contributes to the outstanding dynamic capabilities of the speaker by minimizing harmonic distortion and maintaining performance evenly across the entire frequency spectrum. Beneficial for listeners who enjoy detailed music, as the precise centering of the voice coil through Konex technology ensures that musical nuances are reproduced accurately, leading to a clear and natural listening experience.
