Frequent questions about U-6.5SW v1

Wie hoch ist die Leistung des U-6.5SW v1 von Sundown Audio?

The U-6.5SW v1 subwoofer offers an RMS power of 400 watts, providing powerful and intense bass. This power comes from the dual voice coils, which are available in different ohm variants of 2 or 4 ohms, making it versatile. The combination of aluminum voice coil former and a high-temperature copper voice coil ensures efficient heat dissipation, which is crucial to ensure the expected power output and longevity.

Welche Eigenschaften hat der Gusskorb des U-6.5SW v1?

The U-6.5SW v1 from Sundown Audio features a highly durable cast basket designed for maximum stability and longevity. This is particularly important in applications that require high mechanical stress, such as those encountered with strong and deep bass. This cast basket supports the structural integrity of the subwoofer by minimizing resonances and allowing for a secure mounting. Such features contribute to improving sound quality by enhancing the precision and clarity of the bass output.

Wie beeinflusst der Aluminium-Schwingspulenformer die Leistung des U-6.5SW v1?

The aluminum voice coil former of the U-6.5SW v1 subwoofer plays a crucial role in heat dissipation. Thanks to the excellent thermal conductivity of aluminum, the temperature of the voice coil can be effectively lowered during operation. This protects the voice coil from overheating and allows for a consistent power output of 400 watts RMS. Additionally, the high thermal conductivity of the aluminum former improves the efficiency of the subwoofer, leading to an overall better sound performance.

Welche Frequenzparameter definiert den U-6.5SW v1 von Sundown Audio?

The U-6.5SW v1 subwoofer has specific frequency parameters that characterize its performance. With an FS value of 41.9533 Hz for the 2-ohm variant and 38.6925 Hz for the 4-ohm variant, it is optimally tuned to reproduce low frequencies. These parameters are crucial for the sound profile and ensure that the subwoofer is capable of effortlessly delivering rich and powerful bass, which particularly benefits music genres with deep bass emphasis.

Welche Vorteile bieten die doppelt vernähte Sicke des U-6.5SW v1?

The double-stitched edge of the U-6.5SW v1 ensures additional durability and stability of the membrane. This technique effectively prevents the membrane from warping or tearing under high loads, leading to consistent bass reproduction. With this construction, the subwoofer can handle more power by evenly distributing the mechanical stress. This is particularly advantageous for applications where the subwoofer is used intensively over longer periods, as it maintains its performance.

Wie sind die Doppelschwingspulen des U-6.5SW v1 konzipiert?

The dual voice coils of the U-6.5SW v1 subwoofer are available in 2 or 4 ohm variants, allowing for flexible adaptation to different amplifier circuits. This configuration optimizes the adjustment to the desired sound characteristics and enables the subwoofer to be used in various systems. In addition to the choice of resistance, the voice coils contribute to efficient power handling, which in turn reduces heat generation. The combination of these features ensures consistent and reliable performance under different operating conditions.

Wie kann der U-6.5SW v1 in einem Fahrzeug optimiert installiert werden?

For optimal installation in the vehicle, the U-6.5SW v1 is ideally designed for small enclosures with bass reflex openings. With an enclosure tuning that addresses the specifications of the subwoofer, such as VAS values of 2.9053 L (2 Ohm) and 3.7701 L (4 Ohm), a balanced resonance can be achieved. The dimensions of the enclosure should be adjusted to the required volume requirements and cooling channels to efficiently dissipate heat. These considerations support the full realization of bass performance and sound precision in the vehicle environment.

Welche Auswirkungen haben die Kühlkanäle auf die Leistung des U-6.5SW v1?

The integrated cooling channels in the upper plate of the U-6.5SW v1 significantly improve heat dissipation. This feature ensures that the operating temperature of the internal components, especially the voice coil, is maintained within a safe range. Ultimately contributing to consistent performance in heavily used scenarios. Additionally, the signal-to-noise ratio is optimized as there is less thermal compression. The cooling channels are therefore crucial factors that ensure the maximum performance and efficiency of the subwoofer, even under high load.

Welche technischen Eigenschaften unterstützen die Bassperformance des U-6.5SW v1?

The U-6.5SW v1 from Sundown Audio offers a bass performance that is optimized by various technical features. Its Thiele-Small parameters, such as the Qts value of 0.4937 for the 2-ohm version, are designed to promote expressive bass reproduction. An Le value of 4.0112 mH contributes to controlling the impedance in the high-frequency range, while an Xmax of 19mm allows for large diaphragm excursions without distortion. These aspects work together to produce deep, clear bass and are crucial for the performance of a subwoofer in this class.

Welche Vorteile bieten die praktischen Federklemmen des U-6.5SW v1?

The practical spring clips of the U-6.5SW v1 subwoofer allow for a quick and secure cable connection, simplifying installation and optimizing electrical conduction. These clips are designed for cables up to 4mm², ensuring a stable connection and minimizing signal loss. Especially in high-power applications, this can have a decisive impact on sound quality and performance. This type of clamp connection enhances the user experience, as it guarantees a repeatable and reliable connection that is easy and straightforward to handle, even with frequent reconfiguration.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
