Frequent questions about Signum SX840

Welche Leistung bietet der Signum SX840 von ESX?

The Signum SX840 from ESX delivers remarkable performance with 300 watts RMS and a maximum power of 600 watts. This high power capability enables a powerful, deep bass that supports high-quality sound reproduction. The rated power ensures a dynamic stroke, while the subwoofer unleashes its maximum power at full load. Especially if you enjoy listening to music with intense bass, you will appreciate the advanced technology built into this subwoofer. The thoughtful design ensures a long-term stable performance.

Wie tief ist die Einbautiefe des Signum SX840 Subwoofers?

The Signum SX840 subwoofer has a mounting depth of 114 mm. This relatively shallow mounting depth allows for versatile installation in different vehicle types and enclosure types, without having to compromise on bass performance. Due to its compact design, the subwoofer is ideal for tight spaces. The mounting depth plays a crucial role in implementation in vehicles, especially when you are making your own audio configurations to achieve the best sound in your car.

Welche Materialien werden im Signum SX840 verwendet?

The Signum SX840 uses high-quality materials such as a sturdy aluminum basket and a single Nomex spider core. The aluminum basket provides the necessary rigidity and stability to minimize vibrations, while the Nomex spider core ensures additional durability. Together with a ventilated pole core, the efficiency of the subwoofer is maximized by being able to dissipate heat during intense operating phases. This combination not only enhances sound quality but also contributes to the longevity of the subwoofer.

Welche Impedanz hat der Signum SX840 von ESX?

The Signum SX840 subwoofer from ESX has an impedance of 4 Ω. This impedance is commonly found in many car hi-fi components and ensures that the subwoofer can be easily supported by a variety of amplifiers. With proper impedance matching, you can optimize the efficiency of power output and achieve a clearer, distortion-free bass sound. When planning your car audio system, it is important to pay attention to this electrical specification.

Welche Schwingspule verwendet der Signum SX840?

The Signum SX840 is equipped with a 50 mm long voice coil that has a winding height of 15 mm. This dimensioning allows for effective control of the diaphragm movement, enabling the subwoofer to produce precise bass without distortion. The voice coil is essential for sound quality, as it translates the electromagnetic signal into mechanical movement. The use of a long voice coil allows for a longer linear stroke, which is particularly beneficial in low frequency ranges.

Welche Rolle spielt der Doppelmagnet im Signum SX840?

The Signum SX840 is equipped with a double magnet of 2 x 1.3 kg. This double magnet serves to provide the magnetic field for the voice coil and ensures higher efficiency of the subwoofer in converting electrical signals into acoustic energy. The magnet not only improves sensitivity and sound pressure level but also increases the load capacity of the subwoofer. The combined magnet generates a stronger driving force, resulting in a more dynamic and louder bass.

Welche Abmessungen hat der Signum SX840 Subwoofer?

The Signum SX840 subwoofer has a diameter of 20 cm (8 inches) and a mounting diameter of 189 mm. This compact size allows for flexible installation in a variety of enclosures and vehicle types. The precise measurements are crucial during installation to ensure a perfect fit and avoid resonances. The subwoofer size significantly influences the sound character, with the 20 cm being optimal for powerful bass without compromising playback quality. The dimensions facilitate adaptation to individual requirements.

Wie verbessert der belüftete Polkern die Leistung des Signum SX840?

The ventilated pole core of the Signum SX840 significantly contributes to improving heat dissipation by allowing cool air to circulate through the core center. This process reduces thermal stress on the voice coil, especially during intense use, preventing overheating and increasing reliability. Effective cooling is essential to minimize distortion and maintain consistent audio performance. Especially during long listening sessions, you benefit from the consistent sound quality achieved through the enhanced air circulation design.

Ist der Signum SX840 für bestimmte Fahrzeugmarken geeignet?

The Signum SX840 fits into a variety of vehicle types due to its dimensions and installation depth of 114 mm. Although there are no specific brand model requirements in the description, the universal design allows this subwoofer to be integrated into many common car enclosures, provided there is enough space. During installation, care must be taken to ensure that all electrical connections are made cleanly to achieve optimal performance. Especially for the car audio enthusiast, the subwoofer design offers a wide range of installation options.

Wie beeinflusst X-Max die Klangqualität des Signum SX840?

The Signum SX840 has an X-Max of +/- 13 mm, which indicates the maximum linear excursion before the subwoofer begins to distort. X-Max is crucial for the reproduction of particularly low frequencies, as it shows how far the diaphragm can move in both directions to produce deep bass notes. The larger the X-Max value, the more powerful and uncolored the bass can be produced. This specification ensures that the subwoofer produces clear, distortion-free sounds even at high volumes, which can significantly enhance your listening experience.

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!
