Equipped with a 30 mm CCA voice coil, it ensures efficient conversion of electrical energy into sound pressure. The fiber-reinforced paper cone provides optimal stiffness and reduces distortion, while the resonance-optimized steel basket ensures structural stability and low self-resonance. The speaker features a ferrite magnet, which provides strong magnetic attraction and contributes to performance.

What frequencies can the GZCM 8.0XSPL reproduce?

The GZCM 8.0XSPL midrange driver from Ground Zero is capable of covering an impressive frequency range from 120 Hz to 11 kHz. This bandwidth allows the speaker to reproduce both low and mid frequencies with outstanding clarity, making it an ideal choice for a variety of audio applications. With an efficiency rating of 95 dB, the speaker can operate loudly and efficiently even with low power input. The resonance frequency is at 81 Hz, providing efficient reproduction particularly in the low-frequency range.

Is the GZCM 8.0XSPL weather-resistant?

Yes, the GZCM 8.0XSPL is both UV-resistant and water-repellent, making it well-suited for outdoor applications or humid environments. The fiber-reinforced paper cone is specially treated to withstand harmful environmental influences such as sun and rain. These robust features make the speaker suitable for use in various climatic conditions without compromising sound quality or durability. This makes it the ideal companion for outdoor events or installations in vehicles that are frequently exposed to the elements.

What is the installation depth of the GZCM 8.0XSPL?

The installation depth of the GZCM 8.0XSPL midrange speaker is 84 mm. This should be taken into account when planning installation projects to ensure there is enough space for a proper installation. The specific installation depth allows for a variety of installation applications, whether in vehicles or stationary audio systems. The speaker also requires an installation diameter of 182 mm, which ensures stable mounting and a perfect fit. Especially with modern vehicle designs, it is important to pay close attention to the installation dimensions to ensure seamless integration.

What role does the ferrite magnet play in the GZCM 8.0XSPL?

The ferrite magnet in the GZCM 8.0XSPL is crucial for the speaker's performance. Ferrite magnets are known for their high magnetic strength and heat resistance, which, combined with the 30 mm CCA voice coil, guarantees high efficiency and powerful sound reproduction. The use of ferrite achieves a stable and lasting magnetic field strength, which focuses on precise sound reproduction and minimal distortion. Especially in high-performance applications, the choice of this magnet material is advantageous as it is robust and offers cost-effective performance.

What is the efficiency of the GZCM 8.0XSPL?

The efficiency of the GZCM 8.0XSPL is 95 dB. This means that the speaker is efficiently able to convert electrical energy into acoustic energy without significant power loss. A high efficiency like this is particularly beneficial in situations where available power is limited or high volume is desired with low energy input. The effective efficiency contributes to clear and assertive sound reproduction, making the speaker suitable for demanding applications where power and precision are paramount.

Is the GZCM 8.0XSPL compatible with my vehicle?

The compatibility of the GZCM 8.0XSPL with a vehicle primarily depends on the installation dimensions. With a diameter of 200 mm, an installation diameter of 182 mm, and an installation depth of 84 mm, the speaker is designed to fit into many standard speaker enclosures. However, it is important to check the dimensions of the existing speaker openings to ensure that a proper fit is possible. In custom installation projects, it may be necessary to modify existing openings or use appropriate installation adapters.

What materials are used in the GZCM 8.0XSPL?

The GZCM 8.0XSPL uses a range of high-quality materials for its construction. It features a fiber-reinforced paper diaphragm that is stiff enough to minimize distortion without losing flexibility. The resonance-optimized steel basket ensures structural integrity, while the 30 mm CCA voice coil provides efficient energy transfer. Additionally, a paper dust cap selectively dampens certain frequencies and refines the sound. This choice of materials supports the speaker's ability to deliver clear and reliable performance even under high load.

Why is the paper diaphragm of the GZCM 8.0XSPL water-resistant?

The paper diaphragm of the GZCM 8.0XSPL is specially reinforced and treated to be water-resistant, preparing the speaker for use in various environments. This treatment protects the diaphragm from moisture ingress, which could weaken the material and affect sound quality. The impregnation of the diaphragm also ensures durability and resilience against environmental influences, which is particularly important for audio applications outdoors or in moisture-prone areas. These features make the speaker particularly versatile in application and protect against premature wear.

How is the GZCM 8.0XSPL classified in terms of sound quality?

The GZCM 8.0XSPL from Ground Zero offers impressive sound quality thanks to its sophisticated technical specifications. The 30 mm CCA voice coil and the resonance-optimized steel basket contribute to precise sound reproduction, while the fiber-reinforced and water-resistant paper diaphragm ensures clear, undistorted midrange and effectively handles harmonics. With a power handling capacity of up to 420 watts, the speaker remains stable even at high volumes. This is supported by a high efficiency of 95 dB, ensuring that the GZCM 8.0XSPL reliably maintains its sound quality even under demanding conditions.
