Frequently Asked Questions about E10 v.4

Welche Leistung hat der Sundown Audio E10 v.4?

The Sundown Audio E10 v.4 has an RMS power of 500 watts, making it ideal for high-performance audio applications in cars. Equipped with a 2.5-inch aluminum voice coil, it ensures efficient heat dissipation, which is essential for consistent power delivery. The subwoofer is capable of achieving enormous membrane excursions of up to 14 mm XMAX in each direction, a feature that is rather unusual in this price range. This gives the E10 v.4 an above-average robustness and sound quality. With an impedance option of either D2 or D4, the subwoofer can be flexibly integrated into various audio systems.

Welche Abmessungen hat der Sundown Audio E10 v.4 und wie beeinflusst das die Installation?

The Sundown Audio E10 v.4 has a depth of 14.28 cm, an outer diameter of 25.4 cm, and a cutout diameter of 22.8 cm. These dimensions must be considered when installing in a vehicle, as they determine whether the subwoofer fits in the designated installation space. To achieve the best sound quality, installation in a bass reflex enclosure with a recommended volume of 28 liters and a port area of 96 cm² is optimal. The recommended tuning for the enclosure is 35 Hz to accurately reproduce deep bass.

Welche Materialien werden im Sundown Audio E10 v.4 verwendet?

The Sundown Audio E10 v.4 uses high-quality materials to ensure robustness and durability. The voice coil is made of aluminum, which provides outstanding heat dissipation. The copper voice coil wire is 4-layered and high-temperature resistant, maximizing power handling. The centering spider is made from a poly-cotton blend, which offers more strength and stability, and is additionally glued and screwed to the frame. The frame itself is made of high-strength stamped steel, providing additional structural strength, especially at high volumes.

Welche besonderen Merkmale hat der Sundown Audio E10 v.4?

The Sundown Audio E10 v.4 is characterized by special features, such as the extremely high XMAX of 14 mm per direction, which ensures powerful bass. It has spring-loaded terminals that secure the connections and stitched 'Mini-XL' wires to strengthen solder joints and prevent failures due to fatigue. The motor ventilation system, adopted from the SA series, increases cooling performance, ensuring thermally stable operation. The use of durable materials ensures that the subwoofer maintains its optimized sound quality even under load.

Welche T/S-Parameter hat der Sundown Audio E10 v.4?

The Sundown Audio E10 v.4 has significant Thiele-Small parameters that characterize its performance. For the D2 model, for example, RE is 4.030 Ohms, FS is at 33.270 Hz, and VAS is 21.124 liters. Qes is at 0.525, Qms at 3.657, and Qts at 0.459, which allows for high sensitivity and precision in bass reproduction. The effective displacement field BL is at 16.392 NA and Mms is 167.587 grams, which describes the weight of the diaphragm along with moving parts. These parameters are crucial for acoustic calculations and cabinet tuning.

Welche Impedanzoptionen bietet der Sundown Audio E10 v.4?

The Sundown Audio E10 v.4 offers two impedance options to choose from: D2 and D4. The D2 model has a RE of 4.030 ohms, while the D4 model has a RE of 6.130 ohms. These different impedances allow for flexibility in configuring audio systems, especially when it comes to tuning the amplifiers. Depending on system requirements, the appropriate variant can be selected to ensure optimal performance output. By allowing the coils to be connected in parallel or series, different total impedances can be achieved for precise matching to the amplifier.

Welche Gehäusearten werden für den Sundown Audio E10 v.4 empfohlen?

The Sundown Audio E10 v.4 is specifically designed for bass reflex enclosures. A sealed enclosure is not recommended, as it would not allow for optimal bass reproduction. The suggested bass reflex enclosure has a volume of 28 liters to ensure the best possible performance and efficiency. Tuning to 35 Hz allows for deep bass waves and a precise sound image. The recommended port area is 96 cm² to optimize airflow at high power levels. These specifications ensure that the subwoofer can fully utilize its maximum sound capabilities.

Für welche Fahrzeugtypen eignet sich der Sundown Audio E10 v.4?

Although the Sundown Audio E10 v.4 was not exclusively designed for specific car brands or models, its installation dimensions can serve as a guideline. With an installation depth of 14.28 cm, an outer diameter of 25.4 cm, and an installation diameter of 22.8 cm, it is suitable for many standard enclosures and installation locations. Vehicles with sufficient trunk space provide ideal conditions for integrating the subwoofer along with its recommended bass reflex enclosure. Before installation, it is essential to check whether the available space meets the dimensions to achieve the best possible sound quality.

Wie stellt der Sundown Audio E10 v.4 die Wärmeableitung sicher?

The Sundown Audio E10 v.4 ensures efficient heat dissipation through a variety of technical features. The 2.5-inch aluminum voice coil is specifically designed for excellent thermal efficiency to minimize heat buildup. Additionally, the subwoofer is equipped with a motor ventilation system based on the proven SA series from Sundown Audio. This innovative cooling technology ensures that the operating temperature remains constant even under intense load. These features enable stable operation even at high continuous power and sustainably increase the lifespan of the subwoofer.

Warum ist die Zentrierspinne des Sundown Audio E10 v.4 besonders robust?

The spider of the Sundown Audio E10 v.4 is made from a special poly-cotton blend designed for high mechanical load capacity. This material choice provides not only stability but also a certain flexibility to effectively dampen vibrations. Another aspect is the double securing: the spider is both screwed and glued to the frame, which significantly increases the structural integrity during intense use. This construction detail is unusual in this price range and ensures the subwoofer's ability to function without performance loss over long periods.
