Frequent questions about Zeus ZST8D4

Welche Einbautiefe hat der HiFonics Zeus ZST-8D4 Subwoofer?

The HiFonics Zeus ZST-8D4 subwoofer is characterized by a very low installation depth of only 78 mm. This flat design allows for easy installation in vehicles where conventional subwoofers do not fit due to their depth. Especially in situations with limited space in the car, the ZST-8D4 offers an excellent solution to integrate powerful bass without the need for extensive modifications to the enclosure. However, this design requires the use of a special diaphragm material to ensure sound quality and stability.

Welche Impedanz hat der HiFonics Zeus ZST-8D4 Subwoofer?

The HiFonics Zeus ZST-8D4 is equipped with a dual 4 + 4 Ohm voice coil. This specification offers flexibility in wiring, as you can operate the subwoofer in different configurations to achieve the appropriate ohm rating for your amplifier. The 50 mm voice coil allows for high excursions of up to ±15 mm, resulting in deep and powerful bass output. This dual impedance is ideal for users who want to optimally adjust the performance of their audio system.

Welche Materialien werden für die Membran des Zeus ZST-8D4 verwendet?

The Zeus ZST-8D4 from HiFonics uses a membrane made of a fiberglass/carbon composite material. This material is extremely hard and ensures that at high excursions, the bass is reproduced clearly and without distortion. Conventional materials like paper or plastic would not be suitable for flat subwoofers, as they would negatively affect stability and sound quality. The fiberglass/carbon composite allows for the flat design to be realized without compromising performance.

Welche RMS-Leistung hat der HiFonics Zeus ZST-8D4?

The HiFonics Zeus ZST-8D4 subwoofer has an RMS power of 250 watts. This means that the subwoofer can be operated continuously at this power without any damage. At the same time, it offers a maximum power of 500 watts, which is designed for short peaks. This power capability makes the ZST-8D4 an excellent choice for users looking for powerful bass for their vehicle audio system. This enables impressive sound performance even at higher volumes.

Für welche Gehäusevolumen ist der HiFonics Zeus ZST-8D4 geeignet?

The HiFonics Zeus ZST-8D4 subwoofer unfolds its full potential in a sealed enclosure volume of 10 to 15 liters. Within this range, the subwoofer achieves optimized bass reproduction and sound quality. Alternatively, it can also be operated in a bass reflex tuning, which requires a slightly larger enclosure volume. This operating mode allows for even more powerful bass and is ideal for users who prefer a more intense bass reproduction and are willing to sacrifice a bit more space in the vehicle.

Welchen Durchmesser hat der HiFonics Zeus ZST-8D4 Subwoofer?

The HiFonics Zeus ZST-8D4 subwoofer has a diameter of 20 cm, which is approximately 8 inches. This size allows for an optimal balance between bass performance and installation possibilities in the vehicle. Thus, the subwoofer is a versatile option for various types of vehicles that must cope with limited installation space. Due to its compact dimensions, the ZST-8D4 is also suitable for use in vehicles where larger subwoofers cannot be installed.

Welche Frequenz hat der HiFonics Zeus ZST-8D4 Subwoofer?

The HiFonics Zeus ZST-8D4 subwoofer has a free air resonance frequency (Fs) of 40.7 Hz. This frequency indicates at which vibration the subwoofer reaches its natural resonance, resulting in a strong foundation of the lower frequencies. With a Qts value of 0.59 and a VAS of 10.1 liters, the ZST-8D4 is suitable for applications in smaller enclosures, while the frequency response promises deep bass. The combination of these parameters makes it ideal for car audio systems.

Welche Besonderheiten weist der Magnet des Zeus ZST-8D4 auf?

The magnet of the HiFonics Zeus ZST-8D4 is equipped with a double magnet of 2 x 20 ounces (2 x 0.56 kg). This construction effectively supports the voice coil, allows for high power output, and ensures precise reproduction of low frequencies. The blue magnet protector protects the magnet from external influences and mechanical damage. The size and strength of the magnet enable the subwoofer to produce impressive bass that provides dynamic sound even in demanding driving situations.

Welche Abmessungen hat der Stahlkorb des HiFonics Zeus ZST-8D4?

The steel basket of the HiFonics Zeus ZST-8D4 subwoofer is designed in a robust flat construction and has an outer diameter of 182 mm. This flat yet stable design not only allows for space-saving installation but also ensures a safer fit within the vehicle's architecture. Thanks to the high-quality steel basket, the diaphragm remains well stabilized even during intense bass playback, contributing to a consistently clear sound image. The dimensions are optimally adapted for tight installation conditions.

Wie wirkt sich die flache Bauweise des Zeus ZST-8D4 auf die Klangqualität aus?

The flat design of the HiFonics Zeus ZST-8D4 does not compromise sound quality, but allows for high bass excursions without distortion thanks to the fiberglass/carbon membrane. This choice of material compensates for the increasingly deeper cone shape and maintains acoustic integrity. Even under extreme sound conditions, the sound remains clear and dynamic. Especially if you enjoy listening to music loudly, the ZST-8D4 thus combines space-saving design with outstanding acoustic performance, making it ideal for installation in various types of vehicles.

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!
