This dual impedance enables the subwoofer to be connected either in series or parallel, depending on the amplifier's requirements and the specific vehicle installation. An impedance of 4+4 Ω provides an optimal balance between power and efficiency, ensuring that the QXS8D4 operates reliably in both lower-powered and higher-powered systems.

Wie tief ist die Einbautiefe des ESX Quantum QXS8D4 Subwoofers und welche Einbauöffnung ist erforderlich?

The ESX Quantum QXS8D4 subwoofer has a mounting depth of 78 mm, allowing for compact integration into various vehicle types. The required installation opening is 182 mm, enabling the subwoofer to be easily installed in most standard enclosures. These specific dimensions ensure that the QXS8D4 can be optimally placed without extensive modifications to the vehicle's enclosure being necessary. This allows for a simple and precise installation despite the robust construction of the subwoofer.

Welche Materialien werden bei der Membran des Quantum QXS8D4 verwendet und welche Vorteile bieten sie?

The membrane of the Quantum QXS8D4 subwoofer is made of fiberglass, which ensures high stability and minimal deformation at high power levels. Fiberglass materials provide excellent strength and flexibility, allowing the membrane to produce precise and distortion-free vibrations. This contributes to clear and powerful bass reproduction, even under intense operating conditions. The use of fiberglass in the membrane ensures that the QXS8D4 delivers consistent performance while remaining durable and resistant to the mechanical stresses of subwoofer operation.

Wie beeinflusst die 50 mm CCAW Schwingspule auf Glasfaser-Träger die Leistung des ESX Quantum QXS8D4?

The 50 mm CCAW (Copper-Clad Aluminum Wire) voice coil on a fiberglass carrier in the ESX Quantum QXS8D4 subwoofer enables efficient heat dissipation and a stable magnetic environment. This configuration reduces electrical resistance and increases the thermal capacity of the voice coil, allowing for higher power consumption without overheating. The fiberglass carrier provides additional strength and precision, ensuring that the voice coil delivers consistent and distortion-free performance at high frequencies. This significantly contributes to the excellent sound quality and durability of the QXS8D4.

Welche Vorteile bietet der 40 oz. Doppelmagnet-Antrieb des Quantum QXS8D4 Subwoofers?

The 40 oz. dual magnet drive in the Quantum QXS8D4 subwoofer offers increased magnetic force and improved linearity of movement. The dual magnet configuration exerts a more uniform force on the voice coil, resulting in more precise and powerful bass reproduction. This design minimizes distortion and enhances the efficiency of the subwoofer by allowing for a more stable and controlled vibration of the diaphragm. Especially under high power demands, the dual magnet drive ensures reliable performance and extends the lifespan of the subwoofer.

Welche technischen Merkmale unterstützen die hohe Klangqualität des Quantum QXS8D4 Subwoofers?

The Quantum QXS8D4 subwoofer is characterized by several technical features that contribute to high sound quality. These include the fiberglass membrane, which ensures minimal deformation and distortion, as well as the 50 mm CCAW voice coil on a fiberglass carrier, which provides efficient heat dissipation and stable magnetic fields. Additionally, the robust steel basket flat construction allows for precise resonance control and minimizes unwanted vibrations. The +/- 15 mm X-Max ensures a large excursion of the membrane, enabling deeper and more precise bass reproduction. This combination of features guarantees clear and powerful audio playback.

Wie flexibel ist der ESX Quantum QXS8D4 Subwoofer in verschiedenen Anwendungsszenarien?

The ESX Quantum QXS8D4 subwoofer offers high flexibility in various application scenarios due to its robust construction and versatile technical specifications. With a mounting depth of 78 mm and a cutout size of 182 mm, it fits into a variety of vehicle enclosures without requiring extensive modifications. The impedance of 4+4 Ω and the high power handling of 250/500 watts RMS/Max. allow for use in different audio setups, whether in compact vehicles or powerful audio systems. Additionally, the quality of the materials used, such as the fiberglass membrane and the dual magnet drive, ensures consistent performance under various operating conditions.

Welche Installationshinweise gibt es für den Quantum QXS8D4 bezüglich der Platzierung im Fahrzeug?

For the installation of the Quantum QXS8D4 subwoofer, it is advisable to ensure a stable and vibration-free placement in the vehicle. The installation depth of 78 mm and the cutout size of 182 mm should be considered when selecting the enclosure to ensure an optimal fit. The robust steel basket in flat design allows for flexible placement, whether in the trunk, under the seats, or in special subwoofer compartments. Correct alignment and fastening are essential to minimize resonance and unwanted vibrations, allowing the fiberglass membrane and the voice coil to operate efficiently.

Wie unterstützt die robuste Stahlkorb-Flachbauweise des QXS8D4 die Langlebigkeit und Leistung?

The robust steel basket flat construction of the QXS8D4 subwoofer significantly contributes to its durability and stable performance. A stable steel basket prevents deformation and structural weaknesses under high loads, maintaining the integrity of the subwoofer even during intense bass performances. This construction minimizes vibrations and resonances, leading to clearer and more precise sound reproduction. Additionally, the solid steel basket provides a secure hold for internal components such as the dual-magnet drive and the fiberglass membrane, which increases the overall lifespan of the QXS8D4 and ensures reliable performance over long periods.

Welche Bedeutung hat der +/- 15 mm X-Max für die Performance des Quantum QXS8D4 Subwoofers?

The +/- 15 mm X-Max of the Quantum QXS8D4 subwoofer indicates the maximum linear displacement of the diaphragm and is a crucial factor for bass performance. A high X-Max value means that the diaphragm can move further, allowing for deeper and more powerful bass frequencies. With the QXS8D4, this X-Max ensures precise control over diaphragm movements, even at high volumes and demanding applications. This reduces distortion and provides a clearer reproduction of low frequencies, allowing the subwoofer to achieve impressive depth and dynamics in sound reproduction.

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!
