Frequent questions about K2 Power SUB25KXS

Wie hoch ist die Nennleistung des Focal K2 Power SUB25KXS?

The rated power of the Focal K2 Power SUB25KXS is 350W RMS. This means that the subwoofer is capable of continuously providing a power output of 350 watts. This is particularly important to ensure consistent and reliable sound reproduction, especially if you like to listen to music at high volumes. The maximum power is 700 watts, which covers short-term power outputs to reproduce sudden sound peaks without distortion. With a sensitivity of 84.5dB (2.83/1m), the subwoofer optimizes sound output even at low amplifier power.

Was ist die Membran des K2 Power SUB25KXS und woraus besteht sie?

The membrane of the K2 Power SUB25KXS is made from a K2 sandwich material. This construction leads to a lightweight yet robust structure, which is essential for responsive and precise sound reproduction. The use of different materials in the sandwich construction ensures an excellent balance between stiffness and minimal mass. Additionally, the butyl surround contributes to flexibility and durability, which is particularly advantageous under high power demands. This combination allows for detailed audio representation across a wide frequency spectrum.

Welche Rolle spielt der Schwingspulendurchmesser beim K2 Power SUB25KXS?

The voice coil diameter of the K2 Power SUB25KXS is 45mm (1 3/4"), which contributes to the increase in thermal load capacity. A larger voice coil can dissipate more heat, which is advantageous under high load. Additionally, it supports control over the diaphragm movement, leading to better sound precision. The nominal impedance of 4Ω allows for flexible combinations with various amplifiers, which is highly appreciated in sound engineering. The even drive of the diaphragm results in clean sound reproduction, significantly enhancing the listening experience.

Welcher Parameter zeigt die Tieffrequenzfähigkeit des K2 Power SUB25KXS an?

The low-frequency capability of the K2 Power SUB25KXS is determined by the Fs parameter, which is at 35Hz. A low Fs value indicates that the subwoofer can effectively reproduce low frequencies. Another indicator is the F-3 value at 36Hz, which describes the frequency at which the sound pressure drops by 3dB. Together with the Vas value of 18L and a Qts of 0.8, this results in a subwoofer that offers immense bass qualities, especially in small enclosures. Combined, this produces powerful and clean bass at surprisingly low frequencies.

Was bedeutet der Qts-Wert beim Focal K2 Power SUB25KXS?

The Qts value of a speaker, in the case of the K2 Power SUB25KXS, is 0.8, and is crucial for describing the overall quality of a subwoofer. A Qts of 0.8 typically indicates a design that is suitable for both sealed and bass reflex systems. Combined with a Qes of 0.97 and a Qms of 5, it results in the subwoofer offering flexible installation options and performing well in both compact and larger enclosures. The interplay of these parameters allows for precise tuning to achieve the desired characteristics of bass reproduction.

Welche Aspekte sind bei der Installation des K2 Power SUB25KXS im Auto zu beachten?

When installing the K2 Power SUB25KXS in the car, it is important to pay attention to the dimensions as well as the volume requirements of the chosen enclosure. The subwoofer has a Vas value of 18L, indicating that it can be used in a relatively small enclosure. This is advantageous, especially in situations with limited space, as is often the case in cars. Furthermore, you should ensure that the nominal impedance of 4Ω is compatible with the rest of the system through the integration. The diaphragm movement and radiators must have enough space to optimally utilize the required 14mm Xmax.

Welche Faktoren beeinflussen die maximalen Schwingbewegungen des SUB25KXS?

The maximum oscillation movements of the SUB25KXS are determined by the Xmax value of 14mm. This technical parameter defines how far the diaphragm can be controlled in the linear range before distortion occurs. Additionally, the stiffness of the diaphragm and the surround are significant, as these components are directly related to the oscillation capability. The combined effect of the voice coil with a diameter of 45mm and a Bl value of 11.5 N/A also plays an important role in controlling the diaphragm movement to ensure precise audio reproduction.

Wie beeinflusst die Empfindlichkeit die Leistung des K2 Power SUB25KXS?

The sensitivity of the K2 Power SUB25KXS is 84.5dB (2.83/1m). This specification describes how much sound pressure the subwoofer can produce from one watt of electrical power. Higher sensitivity values mean that less amplifier power is needed to achieve high volume levels. This is particularly relevant when you are operating an audio system with limited amplifier power. The combination of sensitivity with the 350W RMS nominal power optimizes bass reproduction, as powerful and clear bass can be produced even with low amplifier power. This makes the subwoofer ideal for efficient audio systems.

Warum ist die Butyl-Sicke im Focal K2 Power SUB25KXS von Vorteil?

The use of a butyl surround in the Focal K2 Power SUB25KXS is advantageous because it offers high resistance to environmental influences, such as UV radiation and temperature changes, which is particularly important in vehicles. Butyl is also known for its flexibility and durability, leading to exceptional membrane movement capability. Especially in high-performance audio components, the efficiency of the surround materials plays a crucial role. It supports the membrane's ability to vibrate without interference, ensuring accurate and powerful bass reproduction.

Welche Bedeutung hat der Sd-Wert beim K2 Power SUB25KXS und wie beeinflusst er den Klang?

The Sd value, sound radiation area, is 327cm² for the K2 Power SUB25KXS. This parameter is crucial for determining the efficiency with which a subwoofer radiates the generated sound pressure into the room. Larger Sd values typically allow for higher volume levels, as more air is moved with the same diaphragm excursion. A high Sd value combined with an optimal Xmax of 14mm enables this woofer to reproduce deep frequencies evenly and without distortion at high sound pressure levels. This way, you benefit from powerful and rumble-free bass sounds at any volume.

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!
