Frequent questions about Ultra T-30

Was zeichnet den Ultra T-30 Kalotten-Hochtöner von Ground Zero besonders aus?

The Ultra T-30 dome tweeter from Ground Zero impresses with its extraordinarily precise sound reproduction and high-quality craftsmanship. Especially if you enjoy listening to music at high volumes, you will benefit from the wide frequency range of 1000 Hz to 26 kHz, which captures many fine details. Another important factor is the top-notch combination of ventilated voice coil and lightweight CCA diaphragm. This ensures high efficiency and low distortion – even at demanding volume levels. The CNC-milled aluminum housing not only looks elegant but also supports special acoustic damping. This allows sound to be evenly distributed, and you experience a clear, natural sound image. Additionally, the Ultra T-30 is selected in pairs and delivered in a stylish wooden packaging, so you can be sure to always receive consistent technical parameters.

Welche Rolle spielt der belüftete Spulenträger für die Klangqualität?

The ventilated voice coil former in the Ultra T-30 tweeter is responsible for effectively dissipating heat and minimizing unwanted vibrations. When you turn it up a bit more vigorously, the voice coil can heat up quickly. The ventilation immediately dissipates this heat, resulting in a cooler overall system and reduced distortion. At the same time, the technical parameters remain stable, ensuring you a consistently crystal-clear high-frequency range. This ventilation makes the tweeter extremely robust and also contributes to a longer lifespan of your car audio tweeter. The superior construction of Ground Zero with the ventilated voice coil former demonstrates the emphasis on detail and durability, allowing you to enjoy your favorite music in the best possible sound quality.

Wie wird die hohe Effizienz der CCA-Schwingspule im Ultra T-30 erreicht?

The special CCA (Copper Clad Aluminium) voice coil is a real highlight of the Ultra T-30. To provide you with high efficiency, copper is combined with aluminum – resulting in an extremely lightweight yet conductive material. When the tweeter from Ground Zero is driven, this voice coil reacts much faster and more precisely, as less mass needs to be set in motion. Especially if you appreciate detailed highs and a vibrant upper harmonic range, you will feel this advantage. Additionally, the ventilated coil former ensures that the voice coil exhibits a consistent resonance behavior even under high loads. This leads to a high-resolution sound image, where even fine nuances in your music are perfectly represented.

Warum spielt das CNC-gefräste Aluminium-Gehäuse eine so wichtige Rolle?

The CNC-milled aluminum housing of the Ultra T-30 not only serves an aesthetic purpose but also plays a central role in sound quality. Thanks to the precise CNC manufacturing, you can be sure that every contour fits perfectly and that there are no sharp edges that could cause disturbing reflections. Aluminum is also a stable and lightweight material, which helps reduce unwanted resonances. Additionally, the housing supports the integrated pressure distribution, as it dampens vibrations in combination with the special acoustic damping. This allows for clear high-frequency reproduction without disturbing background noise. When you listen to music with many fine details, these features create a particularly pure sound image and give your favorite pieces the necessary brilliance.

Welche Vorteile bietet der integrierte Diffusor im Ultra T-30 Hochtöner?

The integrated diffuser in the high-end car tweeter Ultra T-30 from Ground Zero helps you distribute sound evenly. This prevents sound waves from building up at certain points in the enclosure, causing distortions or peaks. Instead, the diffuser elements ensure that the high frequencies are evenly distributed throughout the vehicle, so that all frequencies reach your ear clearly. Especially when you listen to different music genres – whether rock, pop, or classical – you will notice the gain in clarity and spaciousness. The combination of the diffuser and the special GZ design sound guide optimizes the radiation characteristics, providing you with a very natural listening experience. This way, details play back much more transparently without having to deal with overly emphasized highs.

Ist der Ultra T-30 Kalotten-Hochtöner mit gängigen europäischen Automarken wie BMW, Audi, Mercedes oder VW kompatibel?

The Ultra T-30 dome tweeter can usually be easily integrated into many European vehicle models, as it has a mounting diameter of 60 mm and a mounting depth of 41 mm. This is a common size that can fit in numerous doors or A-pillars. However, if you are wondering whether your specific model has enough space, it is always worth checking the exact installation dimensions of your vehicle. Ground Zero places great importance on flexible application possibilities, which is why the frame is designed to ensure that the tweeter finds a secure hold in many car interiors. With early planning, you can optimally position the Ultra T-30 in most cases to fully exploit its acoustic potential.

Wie beeinflusst die GZ-Design Schallführung den Frequenzgang von 1000 Hz bis 26 kHz?

The specially designed GZ-Design sound guide in the ring radiator tweeter Ultra T-30 ensures that you get a constant radiation angle across the entire frequency spectrum. Technically, it works by reducing reflections and refractions through the shape of the sound guide, directing the sound precisely forward. For you, this means precise reproduction without cancellations or disturbing resonances. Especially in the range from about 1000 Hz up to 26 kHz, the highs remain very linear, giving the sound an open, detail-oriented character. This way, you can hear clean cymbals, delicate vocals, and brilliant guitar solos even in complex musical passages. The result: a natural soundstage that allows you to immerse yourself deeper into your favorite songs.

Was bringt Dir die dokumentierte technische Abschlussprüfung beim Ultra T-30?

For every pair of Ultra T-30, Ground Zero conducts a documented technical final inspection to ensure that you receive only tweeters with precisely tuned parameters. This process ensures, for example, that the frequency responses and impedance values of both models are identical, and that you have a perfectly selected set. Especially if you want a particularly homogeneous stereo sound in your car, you benefit from the fact that the left and right sides are precisely matched. Furthermore, you gain assurance about the reliability and performance of those components that are crucial for a brilliant listening experience across many music genres. The result is a tweeter system that not only sounds great but also consistently performs sustainably.

Warum ist die Resonanzfrequenz von 500 Hz für Dich relevant?

A resonance frequency of 500 Hz means that the membrane of the Ultra T-30 has its own resonance at this point. This is a relatively low value for a car audio tweeter and requires a particularly sophisticated design. Although the nominal frequency response only starts at 1000 Hz, this low resonance helps ensure that the tweeter has fundamentally fewer distortions in its operating range. If you like to listen loudly or prefer musical material with many dynamic fluctuations, the low resonance frequency ensures that no unpleasant peaks or distortions creep in. In practical application, you can integrate this tweeter more flexibly into your system, giving your music more liveliness and clarity.

Für welche Einsatzbereiche eignet sich der Ultra T-30 High-End-Hochtöner besonders gut?

The Ultra T-30 high-end tweeter from Ground Zero is extremely versatile and caters to a wide range of applications. It is perfect for music lovers who value the finest details and desire an authentic stage representation. Whether it's rock, jazz, or electro-heavy tracks – thanks to its frequency response up to 26 kHz, you can hear airy highs clearly and cleanly. Furthermore, this high-end car tweeter impresses with its robust construction featuring a CNC-machined aluminum housing and a ventilated voice coil, providing you with lasting reliability. The Ultra T-30 also showcases its strengths in demanding installations with creative mounting layouts, as its lightweight design and documentation of technical parameters support precise tuning.

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!
