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

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

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.
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.
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.

With the black voice coil offering improved heat dissipation, the subwoofer is well-equipped for high demands in the sound domain.
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.
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.
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.
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.
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.
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.
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.

Honest review

I have b2 rampage 8” v2 Carbon on 1000w at 2 ohm. It sounds great, plenty of power, shaking my car badly but after braking in for around 50-70 hours of playing loud. Before breaking in i was little disapointed. Sundown its on 1000w at 4 ohm. Its not even break in, very stiff and almost impossible to move it by hand. I already feel that x8 is more powerful, sounds really good, shaking car even more than b2 and it kicks you in chest :D dont know if my car will survive after break in. Im happier with x8. B2 is ok but x8 its better even freshly installed from box.
