Frequent questions about Iridium GZIW 250


Welche Größe hat der Iridium GZIW 250 Subwoofer?

The Iridium GZIW 250 from Ground Zero has a diameter of 10 inches, which is exactly 25 cm. This size allows the subwoofer to move enough air and thus produce deep, powerful bass frequencies at high levels. With a mounting depth of only 129 mm, it fits into many conventional installation locations for 25 cm subwoofers, making installation easier. The combination of a compact format and its powerful sound reproduction makes it optimal for sound enthusiasts who value high-quality bass.

Was bedeutet die Klippel-Optimierung beim Iridium GZIW 250?

The Klippel optimization in the Iridium GZIW 250 is a technology for improving the electroacoustic parameters of the subwoofer. This method minimizes distortion and maximizes efficiency, meaning that the subwoofer can produce more sound volume at lower power. Especially at high volumes, Klippel optimization ensures that the sound remains undistorted and that the different frequencies are reproduced accurately. For music lovers who appreciate clear and powerful bass, this technology is particularly advantageous.

Welche Leistung bietet der Iridium GZIW 250?

The Iridium GZIW 250 subwoofer from Ground Zero offers an RMS power of 250 watts. This specification describes the continuous load capacity with which the subwoofer can be operated without damage or overheating. The power recommendation is between 200 and 300 watts, providing sufficient flexibility in selecting a suitable amplifier. With an efficiency of 87 dB, the subwoofer can generate strong bass waves even with low energy input, making it particularly efficient.

Wie beschaffen sind die Materialien des Iridium GZIW 250?

The Iridium GZIW 250 is equipped with a 3D HQPP membrane, known for its stiffness and lightweight construction. This membrane ensures precise bass reproduction. The long-stroke rubber surround allows for high excursions of the membrane while being very robust. A 50 mm copper voice coil is also used, which ensures high thermal resilience. The resonance-optimized steel basket additionally contributes to clear reproduction without unwanted vibrations. This choice of materials supports the high-quality sound reproduction for which the subwoofer was designed.

Welche Frequenzeigenschaften hat der Iridium GZIW 250?

The Iridium GZIW 250 has a resonance frequency of 27 Hz. This low frequency allows the subwoofer to produce particularly deep bass. The damping factor, or 'Qts', is 0.44, which is a good compromise between deep bass capability and speed. With an equivalent air volume (Vas) of 49.3 L, the subwoofer is capable of delivering its full performance in various sized enclosures. These parameters make it particularly flexible for integration into audio systems.

Wie groß ist die maximale Auslenkung des Iridium GZIW 250?

The maximum excursion (Xmax) of the Iridium GZIW 250 is 20 mm. This high excursion property allows the subwoofer to move the diaphragm further, thus producing more intense, deeper bass. This property is especially crucial at high volume levels to achieve clean and precise bass reproduction. The long-stroke rubber surround supports this excursion and ensures that the structure of the diaphragm remains stable even during intense movements. This is particularly appreciated during dynamic music playback.

Welche Einbautiefe hat der Iridium GZIW 250?

The Iridium GZIW 250 subwoofer has a mounting depth of 129 mm. This mounting depth allows for flexibility in placement in various vehicle models, which is particularly important for smooth installation. Thanks to its tailored design, the subwoofer can also be integrated into more compact enclosures without compromising sound performance. This is due to the efficient use of the available volume. This is a significant advantage in vehicles with limited space in the trunk or under the seats.

Was ist die Impedanz des Iridium GZIW 250?

The Iridium GZIW 250 has an impedance of 4 Ohms. This impedance is compatible with most commercially available amplifiers and ensures that the subwoofer can be optimally controlled. The specification of 4 Ohms means that the subwoofer has low electrical resistance when wired correctly, which increases efficiency and improves overall performance. Especially when used in car hi-fi systems, this is a crucial value for compatibility and the optimal performance of the speaker.

Wie wird der Iridium GZIW 250 installiert?

For the installation of the Iridium GZIW 250, note the installation depth of 129 mm and the diameter of 25 cm to ensure that there is enough space in the installation area. The resonance-free steel basket construction should be secured with stable screws to minimize vibrations. An adequate enclosure volume, based on the Vas of 49.3 L, supports efficient bass reproduction. For the electrical installation, a 4-ohm output on the amplifier is required. Ultimately, the correct placement is crucial for the sound, whether in the trunk or elsewhere in the vehicle.

Welche Nutzungsmöglichkeiten bietet die 50 mm Kupferschwingspule beim Iridium GZIW 250?

The 50 mm copper voice coil of the Iridium GZIW 250 ensures high thermal stability and allows the subwoofer to maintain consistent performance even at high volumes. This size of the voice coil helps to dissipate heat more efficiently, which is particularly important for protection against overheating during long music sessions. Additionally, a large copper voice coil improves dynamic sound fidelity by supporting greater movement of the diaphragm, resulting in more precise and powerful bass. This feature is ideal for tuning enthusiasts.
