Frequently Asked Questions about Zeus ZST8D4

What is the installation depth of the HiFonics Zeus ZST-8D4 Subwoofer?

The HiFonics Zeus ZST-8D4 Subwoofer features a very shallow 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 limited space within the car, the ZST-8D4 offers an excellent solution to integrate powerful bass without extensive modifications to the enclosure. However, this design requires the use of a special diaphragm material to ensure sound quality and stability.

What impedance does the HiFonics Zeus ZST-8D4 Subwoofer have?

The HiFonics Zeus ZST-8D4 is equipped with a dual 4 + 4 Ohm voice coil. This specification provides flexibility in wiring, allowing you to operate the subwoofer in different configurations to achieve the appropriate impedance 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.

What materials are used for the diaphragm of the Zeus ZST-8D4?

The Zeus ZST-8D4 from HiFonics uses a diaphragm made of a fiberglass/carbon composite material. This material is extremely rigid and ensures that the bass is reproduced clearly and without distortion at high excursions. 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 without compromising performance.

What is the RMS power of the HiFonics Zeus ZST-8D4?

The HiFonics Zeus ZST-8D4 Subwoofer has an RMS power of 250 watts. This means that the subwoofer can be continuously operated at this power without damage. At the same time, it offers a maximum power of 500 watts, which is designed for short peaks. This 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.

What enclosure volume is the HiFonics Zeus ZST-8D4 suitable for?

The HiFonics Zeus ZST-8D4 Subwoofer reaches 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.

What diameter does the HiFonics Zeus ZST-8D4 Subwoofer have?

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 vehicle types 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.

What frequency does the HiFonics Zeus ZST-8D4 Subwoofer have?

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.

What features does the magnet of the Zeus ZST-8D4 have?

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 the lower 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.

What are the dimensions of the steel basket of the 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 reproduction, contributing to a consistently clear sound. The dimensions are optimally adapted for tight installation conditions.

How does the flat design of the Zeus ZST-8D4 affect sound quality?

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 diaphragm. This material choice compensates for the deepening 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 combines space-saving design with outstanding acoustic performance, making it ideal for installation in different vehicle types.
