Sundown AudioX-8 v4

X8 v4 by Sundown Audio

The Sundown Audio X8 v.4 from the Xv4 series is another subwoofer model in the Xv.4 series, which uses Sundown Audio's "Ultra-High Excursion" suspension and frame designs. With the Sundown Audio X8 v4, Sundown Audio introduces a new platform featuring a massive, triple-stacked motor structure that allows for an extreme X-Max of a full 19mm in each direction. This motor drives a 2.5″ diameter CCAW coil wound on a thick aluminum former, delivering incredible excursion. In the v4 version, the coil has been upgraded to a new "black coil design" that dissipates significantly more heat than the coil in the Xv3 series.

The subwoofers in the Xv4 series are designed for the LOWEST possible frequencies in the smallest possible enclosure, while maintaining extremely low distortion.

Frequent questions about X8 v4

Was ist der maximale X-Max des Sundown Audio X8 v4?

The Sundown Audio X8 v4 offers an impressive X-Max of 19 mm per direction. This excursion is made possible by a triple-stacked motor structure that allows for enormous movement of the diaphragm. With this large X-Max, the subwoofer is capable of reproducing very low frequencies accurately and with minimal distortion. This contributes to providing an exceptional sound experience, especially in small enclosures. This is a significant advantage for audio enthusiasts who desire powerful and clear bass in their sound system.

Welche Leistung hat der X8 v4 Subwoofer?

The X8 v4 from Sundown Audio is equipped with an impressive RMS power handling of 1000 watts, with a maximum power handling that even reaches 2000 watts. This makes the subwoofer extremely powerful and allows it to deliver excellent sound quality even at high volumes. The high power is supported by the robust construction and efficient cooling system of the subwoofer, ensuring excellent heat dissipation even during intense use.

Welche Bauweise hat der X8 v4 Subwoofer von Sundown Audio?

The Sundown Audio X8 v4 is designed for 'Ultra-High Excursion' performance with a triple-stacked motor and a new Mega-Roll v4 surround. This construction helps the subwoofer reproduce unusually deep frequencies with minimal distortion. A 2.5-inch Copper-Clad-Aluminum-Wire (CCAW) voice coil on an aluminum coil form provides stability and heat-related performance efficiency. With the black voice coil offering improved heat dissipation, the subwoofer is well-equipped for high demands in the sound domain.

Welche Gehäuseempfehlungen gibt es für den X8 v4?

For the Sundown Audio X8 v4, a bass reflex enclosure with a volume between 21 and 28 liters is recommended, tuned to 32 Hz. Sealed enclosures are not recommended as they may restrict the dynamic capabilities of the subwoofer. With a recommended port area between 75 and 100 cm², the subwoofer can optimally reproduce its low frequency ranges in this type of enclosure. These specifications help to fully exploit the impressive bass capabilities of the subwoofer and enable a resonance-free sound experience.

Wie lauten die Thiele Small Parameter des X8 v4?

The Sundown Audio X8 v4 has various key features in its Thiele-Small parameters that affect its acoustic performance. For example, the D2 has a resonance frequency (FS) of 41.299 Hz and the D4 has one of 44.150 Hz. The equivalent volume (VAS) is 4.126 liters (D2) and 3.562 liters (D4). The total quality factor (Qts) is 0.356 for the D2 and 0.409 for the D4. These parameters describe the fundamental electrical and mechanical characteristics of the subwoofer, which are crucial for integration into various systems and enclosures.

Welche Einbauanforderungen hat der X8 v4?

The Sundown Audio X8 v4 requires a mounting depth of 17.78 cm and an outer diameter of 22.1 cm. The required cutout measures 18.7 cm in diameter. These specifications are crucial for the correct installation of the subwoofer to ensure that it fits into the intended enclosure and provides the best possible performance. When planning the enclosure design, care should be taken to ensure there is enough space for the subwoofer's movement to achieve optimal sound performance.

Wie beeinflussen die Impedanz-Optionen die Anwendung des X8 v4?

The Sundown Audio X8 v4 is available in impedance options D2 (2 Ohm) and D4 (4 Ohm). The choice between these variants determines how the subwoofer can be connected to an amplifier and what overall impedance the system can be tuned to. A lower resistance (D2) can often draw more power from the amplifier, but it must be ensured that the amplifier can operate with this impedance without overheating. The D4 allows for more flexible wiring of multiple subwoofers, which can be advantageous under certain conditions.

Welche Frequenzgänge unterstützt der X8 v4 Subwoofer?

The Sundown Audio X8 v4 was designed to deliver the lowest possible frequencies in a compact enclosure. With an enormous excursion of 19 mm and a powerful voice coil, the subwoofer is capable of reproducing extremely deep bass frequencies with remarkable clarity. It supports a frequency response that is particularly pronounced in the lower ranges, close to the recommended tuning frequency of 32 Hz. Thus, it is optimal for music lovers who appreciate rich bass.

Welche Vorteile bietet das neue schwarze Spulendesign des X8 v4?

The new black coil design of the Sundown Audio X8 v4 significantly improves heat dissipation compared to the previous series Xv3. This improved thermal efficiency allows the subwoofer to handle greater loads without the risk of overheating. This is particularly crucial for subwoofers that are expected to deliver high power over extended periods. Effective heat dissipation thus contributes to the longevity of the subwoofer and reduces sound distortion during intense use.

Mit welchen Automarken ist der X8 v4 Subwoofer kompatibel?

The Sundown Audio X8 v4 was developed without specific compatibility for automotive brands, but focuses on dimensions that fit many traditional and custom enclosure concepts. The mounting depth of 17.78 cm and an outer diameter of 22.1 cm must be considered to ensure that it fits in the vehicle where it is to be installed. The subwoofer fits in enclosures with the appropriate volume and placement strategy and is adaptable to most vehicles that allow the specified mounting dimensions.

Super guter Subwoofer

Super Subwoofer mit extrem tiefem Bass. Die Kabel sind dick und hochwertig verarbeitet. Es gibt nichts zu beanstanden. Absolut empfehlenswert.

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 .

X-10 v3 d2

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!
