Welche Größe hat der DD Audio Redline SL 712 und wie beeinflusst das seine Leistung?

The DD Audio Redline SL 712 is a 12-inch flat subwoofer, which is approximately 30 cm. This compact size allows for flexible placement, especially in limited spaces, while still delivering strong bass. With an outer diameter of 12 5/8 inches and a cutout diameter of 11 3/16 inches, it fits well into many common enclosures. Its mounting depth of 4 1/8 inches emphasizes the flat design, enabling easy integration into your audio system without compromising on bass performance.

Wie ist die Impedanz des Redline SL 712 konfiguriert?

The Redline SL 712 subwoofer from DD Audio features a dual voice coil impedance configuration that can be used as either D2 or D4. This versatility allows you to choose the appropriate setting based on your amplifier's requirements to achieve either maximum power or higher efficiency. Whether you need a low or a higher impedance, this subwoofer provides you with the flexibility that best suits your specific audio system for optimal sound performance and system compatibility.

Welche installativen Vorteile bietet der DD Audio Redline SL 712 in Bezug auf die Gehäuseanforderungen?

The Redline SL 712 is ideal for ventilated enclosures or enclosures of multiple orders, giving it great versatility in installation. Thanks to its special EROM edging, it is securely fixed in the enclosure and ensures reliable bass reproduction. The compact mounting depth of 4 1/8 inches allows for integration into a variety of installation situations, even in tight spaces. The enclosure should be tuned to the Vas measurement of 32.507 liters to achieve the best acoustic performance and optimally showcase the powerful sound.

Wie beeinflussen die Thiele-Small-Parameter die Leistung des Redline SL 712?

The Thiele-Small parameters of the Redline SL 712, such as Fs (39.03 Hz), QMS (4.556), QES (0.548), and QTS (0.489), are crucial for determining the acoustic properties of the subwoofer. These parameters influence how the subwoofer responds to frequencies and which types of enclosures are best suited. A high QMS indicates good control of the mechanical parts, while QES describes the electrical damping factor. These values assist in optimizing the enclosure for balanced bass reproduction, especially in the lower frequency range, and contribute to the overall performance of the system.

Welche Tipps zur Installation des Redline SL 712 kann ich verwenden?

When installing the Redline SL 712, attention should be paid to the correct dimensions: a mounting diameter of 11 3/16 inches and a mounting depth of 4 1/8 inches are required. Placing it in a ventilated enclosure optimizes bass reproduction, and the enclosure type should be matched to the Vas measurement of 32.507 liters. For optimal performance, the connection cables must be correctly connected, and the impedance configuration (D2 or D4) must be observed. A secure attachment at the installation site prevents vibrations and ensures consistent, powerful bass reproduction.

Kann der Redline SL 712 mit verschiedenen Automarken kompatibel sein?

The Redline SL 712 from DD Audio fits well in many vehicles due to its compact dimensions, especially the installation diameter of 11 3/16 inches and a mounting depth of 4 1/8 inches. Its flexibility allows for adaptation to a variety of car brands by using a enclosure that meets the required specifications. Before installation, it is advisable to measure the available space in the trunk or under the seats to ensure that the subwoofer fits properly without compromising acoustic performance.

Wie beeinflusst die EROM-Einfassung des Redline SL 712 die Basseffizienz?

The special EROM surround of the Redline SL 712 plays a crucial role in increasing bass efficiency. It not only securely holds the subwoofer in the enclosure but also ensures an even distribution of pressure conditions on the cone. This reduces mechanical stress and improves the reproduction of low frequencies. This surround also allows for greater cone excursion, further enhancing low-frequency performance without compromising sound quality, thus providing a more dynamic and clearer bass reproduction.

Welche Rolle spielt die Schwingspule beim Redline SL 712 Subwoofer?

The Redline SL 712 is equipped with a powerful 3-inch voice coil, which plays a crucial role in controlling the subwoofer. This component is essential for converting electrical signals into mechanical movements that drive the cone. A larger voice coil, like that in the SL 712, allows for higher thermal loads and improves performance, while simultaneously optimizing heat dissipation. For you as a user, this means that the subwoofer delivers consistent and distortion-free sound quality even at high volumes.

Wie schwer ist der DD Audio Redline SL 712 Subwoofer und welche Implikationen hat sein Gewicht?

Weighing 9.5 kg, the Redline SL 712 subwoofer features a solid construction designed for durability and stability. The weight contributes to vibration damping and minimizes unwanted resonances that could affect sound quality. When installing, the weight should be taken into account to ensure that existing mounts can hold the subwoofer securely. The stable construction of the SL 712 enhances its ability to deliver powerful, deep frequencies without sound distortion, even at high volumes.

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!
