Frequent questions about AT-28a PRO

Welche Materialien werden im Kalottenhochtöner AT-28a PRO verwendet?

The AT-28a PRO dome tweeter from DD Audio features a 1.1" natural silk fiber dome that provides a clear and smooth sound. The voice coil is made of copper-coated aluminum ribbon wire, which offers excellent conductivity and low mass to facilitate quick movements. The voice coil former is made from a titanium alloy, enhancing durability and thermal resistance. This choice of materials ensures the ideal combination of sound quality and longevity, making this tweeter particularly suitable for demanding audio applications.

Wie ist der frequenzbereich des AT-28a PRO von DD Audio?

The frequency range of the AT-28a PRO from DD Audio extends from 3kHz to 25kHz. This wide frequency range allows for detailed and clear reproduction of high frequencies, which is particularly advantageous in complex audio environments. The tuned neodymium motor technology and the specially designed rear cavity with two chambers help ensure that the frequency response from the dome tweeter remains smooth and distortion-free. This makes the AT-28a PRO particularly suitable for Hi-Fi audio systems that aim for precise and comprehensive music reproduction.

Welche Impedanz hat der AT-28a PRO Hochtöner?

The dome tweeter AT-28a PRO has an impedance of 4 Ohms, making it compatible with most common amplifiers in automotive and home audio applications. The impedance affects how the speaker interacts with the amplifier, and a standard of 4 Ohms is widely used, allowing for easy integration into existing systems. Additionally, the specific impedance value ensures that the tweeter operates efficiently, resulting in a balanced and powerful sound that covers the entire frequency range.

Welche Leistungen kann der AT-28a PRO von DD Audio verarbeiten?

The AT-28a PRO from DD Audio has a maximum power handling of 125 watts and an RMS rating of 50 watts. These power values mean that the tweeter is capable of delivering impressive audio performance both in everyday use and at higher volumes. The maximum load indicates how much power the speaker can handle in the short term, while the RMS specification describes the continuous power that can be handled without damage. This ensures reliable and dynamic audio playback.

Wie beeinflusst die Neodym-Motor Technologie des AT-28a PRO die Leistung?

The neodymium motor technology of the AT-28a PRO ensures a very compact and powerful motor structure that provides efficient magnetic forces to precisely move the diaphragm. Neodymium is an extremely strong magnet that generates high magnetic fields at a lower volume, allowing for smaller and lighter designs. This improves the speaker's response speed, resulting in a clearer and cleaner sound image, ideal for the precise reproduction of higher frequency ranges, which ensures great clarity and richness of detail in audio playback.

Welche Besonderheit hat der rückseitige Hohlraum des DD Audio AT-28a PRO?

The rear cavity of the DD Audio AT-28a PRO is tuned to a two-chamber system, which helps to smooth the frequency response and minimize resonances. This special design allows for better control over the acoustic performance of the tweeter, as it optimally directs the air movements behind the dome. This results in improved sound quality with less distortion in the upper frequency range. Especially in high-quality audio playback, such tuning is crucial to ensure a precise and clear sound image with an uncolored bass range.

Wie werden die Verbindungen beim AT-28a PRO gesichert?

The connections on the AT-28a PRO from DD Audio are equipped with gold-plated screw terminals that ensure optimal conductivity and corrosion resistance. Gold plating is known for its excellent anti-oxidative properties, thus ensuring a permanently lossless signal transmission. Especially in demanding audio solutions, where connection stability is crucial, these high-quality terminals provide the assurance that there is no loss of power or disruption of the audio flow. Easy connection and long-term reliability make this solution particularly user-friendly and effective in use in complex systems.

Welche Einbaumaße hat der Hochtöner AT-28a PRO?

The AT-28a PRO tweeter from DD Audio has a mounting diameter of 40.6 mm and a mounting depth of 17 mm. These dimensions are particularly relevant when it comes to integrating the tweeter into existing speaker systems or vehicle setups. The shallow mounting depth offers flexibility, as it can be used in a variety of surfaces and aircraft. The reduced depth allows for easy installation even in tight spaces without compromising sound quality. Be sure to consider these dimensions when planning the installation to ensure the right fit.

Wie hoch ist der Wirkungsgrad des DD Audio AT-28a PRO?

The efficiency of the AT-28a PRO tweeter is 91.2 dB. This means that this speaker produces a considerable volume at a defined power level, making it particularly efficient in converting electrical energy into acoustic energy. A high efficiency is crucial for maximizing volume without the need for high power amplification. This is advantageous for audio systems, as it allows for clear and powerful sound even with low amplifier controls, which is essential for overall efficiency and recording quality.

Welche besonderen Designmerkmale hat der AT-28a PRO von DD Audio?

The AT-28a PRO from DD Audio is characterized by some special design features, such as the laser-engraved back panel, which is not only aesthetically pleasing but also provides a durable and unique surface. This engraving technique ensures a precise and sharp contour representation that highlights the premium quality of the tweeter. Together with the high-quality materials and sophisticated neodymium motor technology, this detail serves as further proof of the high-quality engineering and meticulous craftsmanship that has gone into every detail of the AT-28a PRO.

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!
