The Aluring 213/185/18 was designed as a mounting ring specifically for 8-inch mid-bass drivers and fits, for example, the ArcAudio ARC8. Its dimensions and drilling specifications are designed to ensure broad compatibility with similar speaker models, as the inner diameter of 185 mm corresponds to many common models. However, it is always important to ensure that the mounting holes and the rings fit perfectly to allow for secure and stable installation. The adaptability of this ring makes it useful for many different speaker systems.

Welche Materialien werden für den Aluring 213/185/18 verwendet?

The Aluring 213/185/18 is made of solid aluminum, which contributes to its durability and high quality. Aluminum is the ideal choice for this application area, as it is not only robust and stable but also lightweight. This means that the mounting ring is both easy to handle and resistant to the usual stresses during vehicle operation. The material also prevents corrosion, which is a significant advantage in the automotive sector, where moisture and temperature fluctuations can occur.

Was sind die Montagevorteile des Aluring 213/185/18 in Fahrzeugen?

The Aluring 213/185/18 offers a range of installation advantages due to its thoughtful dimensions and the use of aluminum. On one hand, the lightweight material ensures easy handling during installation, while on the other hand, the precise manufacturing guarantees a perfect fit, which is particularly beneficial in the vehicle door. Thanks to the different hole sizes, numerous installation options are supported, increasing compatibility with various speaker models. These features reduce vibrations and resonances, leading to improved sound quality.

Ist der Aluring 213/185/18 universell einsetzbar?

The outer diameter of 213 mm and the inner diameter of 185 mm ensure a precise fit for various speaker models. The universal applicability is also supported by the drill holes for M5 and M4 on a bolt circle of 197 mm, allowing for easy integration into a variety of door panels and audio systems. The design supports a stable speaker mounting.

With its precise design, it contributes to resonance-free playback.

Wie erfolgt die Installation des Aluring 213/185/18 in der Türverkleidung?

The installation of the Aluring 213/185/18 in the door panel is technically well thought out. First, the ring is laid out with the appropriate drill holes for M5 or M4 screws on the 197 mm bolt circle, to then be precisely screwed into the door or door panel. The height of 18 mm ensures that the speaker sits securely and is flush with the panel. This provides a clean appearance and prevents unwanted movements. Always use appropriate tools to avoid damaging the aluminum surface.

Welche Vorteile bietet der massive Aluminiumaufbau des Aluring 213/185/18?

The massive aluminum construction of the Aluring 213/185/18 offers significant advantages compared to other materials. Aluminum is not only lightweight but also extremely resistant to corrosion and vibrations. This ensures a secure hold of the speakers while minimizing the risk of sound distortion due to resonances or movements. Additionally, the solid design allows it to remain permanently stable even under high loads, which is particularly beneficial in the dynamic environment of a vehicle. This significantly extends the lifespan of the components.

Welche Lautsprechergröße ist optimal für den Aluring 213/185/18 geeignet?

The Aluring 213/185/18 is optimally suited for 8-inch, or 20 cm, speakers.

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!
