Frequently asked questions about SA8 v.3

Welche Leistung bietet der Sundown Audio SA8 v.3?

The Sundown Audio SA8 v.3 subwoofer offers an RMS power of 500 watts. This performance is achieved by the addition of a larger, more powerful motor designed for the 2-inch voice coil. This is made of aluminum and ensures excellent heat dissipation under demanding conditions. This not only improves performance but also supports the sustainable stability of the system. High power meets durability, supported by a high-temperature copper voice coil wire that helps maximize performance in long-term operation. Thus, the SA8 v.3 is well-suited for demanding applications.

Welche Impedanzoptionen hat der SA8 v.3?

The Sundown Audio SA8 v.3 is available in two impedance variants: D2 and D4. D2 stands for a dual voice coil with 2 ohms, while D4 stands for a dual voice coil with 4 ohms. These variants allow you to adjust the subwoofer configuration to different amplifier loads and systems. With the available options, you can ensure that your system harmonizes optimally with the subwoofer to achieve the desired sound quality and performance, whether in sealed or bass reflex enclosures.

Was sind die Thiele-Small-Parameter des SA8 v.3?

The Thiele-Small parameters for the Sundown Audio SA8 v.3 are detailed and vary depending on the impedance version. For the SA8 v.3 with D2, they are as follows: Re(Ohms) = 3.36, FS(Hz) = 38.29, VAS(L) = 6.88, Qes = 0.324, Qms = 6.31, Qts = 0.309, Le(mH) = 2.08, BL(NA) = 18.94, Mms(Grams) = 144, and Cms(uM/N) = 120. For the D4 variant, they are: Re(Ohms) = 6.0, FS(Hz) = 40.0, VAS(L) = 7.17, Qes = 0.392, Qms = 4.31, Qts = 0.36, Le(mH) = 3.32, BL(NA) = 22.06, Mms(Grams) = 126.6, and Cms(uM/N) = 125. These parameters are essential for the design and fine-tuning of the enclosure construction.

Wie ist die lineare Auslenkung des Sundown Audio SA8 v.3?

The Sundown Audio SA8 v.3 offers a linear excursion (Xmax) of 16 mm. This excursion is crucial for reproducing deep bass frequencies with minimal distortion. The subwoofer is designed to allow an excursion of just over 32 mm x-mech. These specified scales of linear excursion contribute to the subwoofer's ability to produce impressively deep tones while maintaining clarity and precision at higher volumes. The powerful motor complements this excursion with a large magnet ID shorting ring, further minimizing distortion.

Wie sollte das Gehäuse für den SA8 v.3 gestaltet sein?

The Sundown Audio SA8 v.3 subwoofer is optimized for multiple enclosure types to achieve its performance to the fullest. For a sealed enclosure, a volume of 8.5 liters is recommended. If you want to build a bass reflex enclosure, the recommended volume is 18.4 liters, with tuning at 35 Hz. Pay attention to a port area of 58 cm² to maximize airflow and minimize distortion. These enclosure parameters are crucial to fully exploit the potential of the Sundown Audio SA8 v.3, which is particularly important in the low-frequency range.

Auf welche Abmessungen sollte ich bei der Installation des SA8 v.3 achten?

For a successful installation of the Sundown Audio SA8 v.3 subwoofer, the dimensions are crucial. The cutout diameter is 18.7 cm, while the outer diameter measures 21.3 cm. The depth is also significant at 16.8 cm. It is particularly important that you consider these dimensions when building or selecting a suitable enclosure, as they can affect the correct mounting and functionality of the subwoofer. Taking these measurements into account ensures that the SA8 v.3 is optimally installed and that the sound quality is not compromised.

Welche Rolle spielt der Faraday-Ring im SA8 v.3?

The Sundown Audio SA8 v.3 is equipped with a large magnet ID short-circuit ring, known as a Faraday ring. This ring plays a crucial role in reducing distortions caused by inductance and inductance fluctuations over the stroke. Together with the powerful motor and optimized voice coil, the Faraday ring helps the subwoofer produce a clean and precise sound. Reducing such distortions is particularly important when it comes to reproducing low frequencies and high volumes, where precision is essential.

Welche Materialien werden für den SA8 v.3 verwendet?

The Sundown Audio SA8 v.3 subwoofer uses high-quality materials that contribute to overall quality and durability. The black 2-inch voice coil former is made of aluminum, which provides excellent heat dissipation. The high-temperature copper voice coil wire is specially selected to ensure high thermal resilience. The aluminum Faraday ring effectively minimizes distortion. Furthermore, the device features spring-loaded terminals and a high-strength, patented aluminum die-cast frame. These materials are carefully chosen to ensure the performance and durability of the SA8 v.3, even under intense applications and over a long period.

Wie beeinflussen die T/S Parameter die Gehäusewahl für den SA8 v.3?

The Thiele-Small parameters of the Sundown Audio SA8 v.3, such as Qts, Vas, and Fs, play a significant role in determining the optimal enclosure size. The Qts values of 0.309 at D2 and 0.36 at D4 strongly influence the type of suitable enclosure, as a low Qts value typically indicates a preference for sealed enclosures, while a higher value is suitable for bass reflex enclosures. Vas indicates the equivalent volume of a rigid, sealed enclosure and is a crucial factor in enclosure design, with values of 6.88 L at D2 and 7.17 L at D4. The right enclosure selection ensures balanced bass reproduction.

Welche Vorteile bietet die Aluminium-Schwingspule des SA8 v.3?

The aluminum voice coil of the Sundown Audio SA8 v.3 offers outstanding advantages in terms of heat dissipation and weight. The choice of aluminum as a material allows for faster heat dissipation, which increases thermal resilience during high-performance operation, thereby improving the stability of the subwoofer. The lighter weight of the coil helps minimize inertia, which in turn enhances the responsiveness of the woofer to quick impulses. These characteristics support the reliable performance of the SA8 v.3 even in high-intensity applications by maximizing operational efficiency and longevity.
