Frequent questions about Ultra 80-GRILL

Was zeichnet das Ultra 80-GRILL von Ground Zero in Bezug auf Design und Material aus?

The Ultra 80-GRILL was developed by the manufacturer Ground Zero with an impressive high-gloss polished surface that not only looks great but also convinces with its robust workmanship. Especially if you place great value on an appealing look in your vehicle, this protective grille can set a real highlight. The combination of the specially designed GZ-Design Hexagon NRG grille and the corresponding aluminum mounting ring ensures optimal stability. This provides you with a durable cover that offers ultimate protection for your midrange speakers in the car hi-fi sector. Aluminum is particularly known for its lightweight yet very resilient structure – ideal if you are looking for performance and durability in one product. You can find more information about the manufacturer Ground Zero in our brand overview, where we also reveal further details about the speaker series.

Wie beeinflusst das GZ-Design Hexagon NRG den Schutz des Lautsprechers?

The GZ-Design Hexagon NRG grid is a specially designed honeycomb structure that provides your speaker system with exceptionally high stability. The hexagonal shape evenly distributes the force acting on the grid, which is particularly advantageous in the case of shocks or vibrations. This way, your midrange speaker, such as the GZ ULTRA M-80 or similar models, is always well protected. Even when you are on uneven roads or like to turn up your music loud, you don't have to worry about damage. Furthermore, the open structure allows for excellent air circulation, which enhances sound performance. This grid thus combines safety and sound quality – an ideal solution if you aim for maximum performance in the car audio sector. Also, check out our technical guide on Ground Zero to learn more about its other functionalities.

Passt das Ultra 80-GRILL auch in Fahrzeuge von BMW, Audi, Mercedes oder VW?

The Ultra 80-GRILL is designed to fit many common vehicles, including popular brands like BMW, Audi, Mercedes, or VW. However, it is crucial in this context to ensure that the required installation dimensions match those of your vehicle. With an outer diameter of 105 mm, an installation diameter of 100 mm, and an installation depth of 7 mm, you have a clear reference for the fit accuracy. Additionally, the Ultra 80-GRILL features a speaker hole circle of 86 mm with four mounting points, which often works in European vehicles. If you want to find out if the grille fits perfectly in your model, you should quickly measure your existing space conditions. For further questions regarding vehicle compatibility, it is worth taking a look at our installation instructions or the Ground Zero product overviews.

Wie installiere ich das Ultra 80-GRILL am besten in meinem Fahrzeug?

For the installation of the Ultra 80-GRILL, it's best to have a few hand tools on hand, such as a small screwdriver or Allen key, depending on the screws provided. First, you should measure exactly where your midrange speaker or speaker system is located. The specified dimensions will help you – 100 mm installation diameter, 105 mm outer diameter, and a speaker hole circle of 86 mm for four fastenings. In the next step, place the included aluminum mounting ring on the speaker before you put on the protective grille. You should ensure that all drill holes align perfectly so that no vibrations occur later. Finally, secure everything tightly with the screws until nothing can move. Especially if you often listen to loud music, the perfect fit of the grille is important to keep your midrange speaker protected in the long term. If you have any uncertainties, our step-by-step guide in the Ground Zero installation section will assist you.

Eignet sich das Ultra 80-GRILL auch für Car Audio Hochtöner oder High-End-Auto-Hochtöner?

Although the Ultra 80-GRILL was primarily designed for midrange speakers like the GZ ULTRA M-80, it can also be used for car audio tweeters in certain cases. However, it heavily depends on the dimensions of your tweeter chassis. If you have a high-end car tweeter in mind that fits as closely as possible to the 100 mm installation diameter and the 86 mm bolt circle, you can install the grill without any issues. Thanks to the aluminum mounting ring and robust design, the Ultra 80-GRILL reliably protects your speaker from mechanical impact. However, make sure that the grill does not obstruct the optimal radiation angle of your tweeter. If you want to be sure, you can find more information on the combination of grills and tweeter systems in our Ground Zero technology FAQ.

Wie trägt die Verarbeitung der Aluminium-Montageringe zur Stabilität bei?

Aluminum is known for its excellent ratio of low weight to high load capacity. You benefit from this with the Ultra 80-GRILL. The included aluminum mounting ring ensures that the grid remains securely fixed to the speaker even under stronger vibrations and shocks. Especially if you like to go on tours and perhaps fire bass-heavy tracks through your midrange drivers, a stable construction is essential. The manufacturing from aluminum also prevents the material from corroding quickly. This way, the mounting ring structure remains intact over a long period and provides reliable support. You can find more information about the different material advantages in our guide to Ground Zero speaker accessories, where fine metal craftsmanship is the focus.

Welche Rolle spielen die genauen Abmessungen bei der Montage des Ultra 80-GRILL?

The exact dimensions are often the be-all and end-all when installing a speaker grill. In the case of the Ultra 80-GRILL from Ground Zero, you have an outer diameter of 105 mm, an installation diameter of 100 mm, an installation depth of 7 mm, and a speaker hole circle of 86 mm (4x). These measurements allow for precise mounting, ensuring that the grill sits firmly and does not create disturbing resonances. Especially if you value the best possible sound, everything should be positioned with millimeter precision. By adhering to the specified dimensions, you ensure that the aluminum mounting ring can be positioned correctly and that the protective function is fully provided. In our installation tips on the topic of Ground Zero speaker grills, we explain in detail how to measure and adjust.

Wie kann das Ultra 80-GRILL die Klangqualität verbessern?

At first glance, one might think that a speaker grille is just a protection that prevents damage. In fact, the Ultra 80-GRILL can influence sound quality by regulating the radiation of your speaker cleanly. The GZ-Design Hexagon NRG structure creates a good balance between protection and air circulation. This reduces disturbing vibrations, allowing your midrange driver (for example, GZ ULTRA M-80) to operate more freely. Additionally, the solid construction of the mounting ring prevents unwanted vibrations from transferring to the speaker system. Even at high volumes or strong bass, your system remains stable. If you want to learn more about the technical background of ring radiator tweeters and midrange drivers, we recommend taking a look at our Ground Zero product guide, where we discuss frequency transitions and their optimization.

Warum ist der Hochglanz-Look nicht nur optisch ansprechend, sondern auch praktisch?

The high-gloss polished surface of the Ultra 80-GRILL not only looks elegant but also offers practical advantages in everyday life. On one hand, high gloss is generally relatively easy to clean, allowing you to quickly remove small dirt with a cloth. On the other hand, the polished surface reflects light in a way that creates a certain shine effect even in darker vehicle environments. Especially if you want to enhance the visual appeal of your vehicle's interior, the grill fits perfectly. Additionally, a smooth surface provides less surface area for dust or dirt particles, making maintenance even easier. If you want to learn more about design updates for your car audio system, you can find numerous ideas for the overall impression of your interior in our Ground Zero styling section.

Für wen lohnt sich das Ultra 80-GRILL besonders?

You love enjoying your favorite songs in the car with the best sound quality and want to optimally protect your valuable speakers? Then the Ultra 80-GRILL is a sensible addition for you. Especially if you often listen to loud music and value crisp mids, you will appreciate the combination of robust GZ-Design Hexagon NRG and high-quality aluminum mounting ring. Even if you enjoy tinkering and customizing your vehicle step by step, this grill system can add a new stylistic nuance. Additionally, it is designed for various Ground Zero midrange speakers, giving you some flexibility for future speaker upgrades.

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!
