Frequently Asked Questions about Helon AX 165-4 EVO 2


What technical features define the Helon AX 165-4 EVO 2?

The Helon AX 165-4 EVO 2 features a 6.5" FKP diaphragm mounted in a die-cast Euronorm chassis. The Nomex spider provides additional stability and precision to the mid-bass driver. A 4-layer 38 mm voice coil ensures efficient heat dissipation and optimal performance. With an impedance of 4 Ohms and a power range of 220/150 Watts, it is ideal for high levels. The outer diameter of the speaker is 166 mm, the installation depth is 71 mm, and the cut-out size is 146 mm.

What is the power capacity of the Helon AX 165-4 EVO 2?

The Helon AX 165-4 EVO 2 delivers a peak power of 220 Watts and an RMS power of 150 Watts. These power specifications allow for a dynamic and powerful sound, particularly excelling at high volumes and low frequency ranges. The 4-layer 38 mm voice coil supports heat dissipation, contributing to increased power stability. Especially if you enjoy listening to music loudly, this configuration ensures clear and distortion-free playback, even under intense use.

How does the die-cast Euronorm chassis affect performance?

The significant die-cast Euronorm chassis of the Helon AX 165-4 EVO 2 not only provides mechanical stability but also reduces resonances that could affect the sound. It creates a robust foundation that perfectly supports the FKP diaphragm and the Nomex spider. This combination prevents distortion and ensures consistent sound quality across the entire frequency spectrum. Particularly in the area of EXTREME KICKBASS that this speaker produces, the role of the chassis is crucial for maintaining sound integrity at high levels.

What functions does the FKP diaphragm serve?

The FKP diaphragm used in the Helon AX 165-4 EVO 2 is crucial for sound generation and distribution. Its material and design are intended to provide both strength and lightness, ensuring reactive and dynamic sound reproduction. This allows even the finest audio nuances to be represented clearly and precisely. In combination with the Nomex spider and the 4-layer voice coil, the diaphragm enables the characteristic powerful level and the ability to reproduce kickbass that distinguishes the speaker.

What are the impedance and power requirements of the Helon AX 165-4 EVO 2?

With an impedance of 4 ohms, the Helon AX 165-4 EVO 2 is suitable for various amplifier systems that match this impedance. Additionally, it has a power capacity of 220 watts peak and 150 watts RMS, making it ideal for powerful sound reproduction. Existing systems should meet or exceed these specifications to ensure optimal sound quality. When installing, it is worthwhile to compare the impedance with the fixed resistance of the rest of the system to ensure maximum efficiency and avoid sound loss.

What dimensions should I consider when installing the Helon AX 165-4 EVO 2?

The outer diameter of the Helon AX 165-4 EVO 2 is 166 mm, while the installation measurement has a diameter of 146 mm. The installation depth is 71 mm, ensuring that the speaker fits into various types of vehicle installations. These dimensions are crucial to ensure that the speaker sits correctly and securely without putting unnecessary pressure on the installation structure. When planning and implementing the installation, these data should be carefully considered to prevent potential interference or loss of sound quality.

What role does the Nomex spider play in the Helon AX 165-4 EVO 2?

The Nomex spider in the Helon AX 165-4 EVO 2 serves to support and center the diaphragm and voice coil in their movement. Nomex, known for its heat resistance and elasticity, allows for precise control and damping of diaphragm movements, enhancing the sound precision of the speaker. This achieves a coherent and consistent sound development, especially at high output levels and EXTREME KICKBASS applications. This structure also increases the lifespan of the speaker, as mechanical stresses are evenly distributed.

How does the voice coil affect the sound reproduction of the Helon AX 165-4 EVO 2?

The 4-layer 38 mm voice coil of the Helon AX 165-4 EVO 2 is responsible for converting electrical signals into mechanical movement that drives the diaphragm. Its multilayer construction allows for more efficient heat dissipation and prevents thermal compression, which is crucial for continuous performance at high volumes. This optimization results in lower distortion and more transparent sound reproduction across the entire performance spectrum. Especially when reproducing high levels, its resistance to temperature fluctuations and mechanical stress is advantageous.

Is the Helon AX 165-4 EVO 2 compatible with my vehicle?

To ensure the compatibility of the Helon AX 165-4 EVO 2 with your vehicle, check the installation dimensions: outer diameter is 166 mm, installation size is 146 mm, and installation depth is 71 mm. These parameters should match the existing speaker cutouts in your vehicle. If your vehicle provides enough space, installation is effectively possible. Make sure that neither cables nor other vehicle elements are obstructed by the mid-bass driver. Accurately measuring these distances is important to ensure a perfect fit and smooth installation.

How does the choice of materials contribute to the performance of the Helon AX 165-4 EVO 2?

The choice of materials for the Helon AX 165-4 EVO 2 has been deliberately made to ensure outstanding sound performance. The FKP diaphragm provides precise sound reproduction due to its lightweight yet rigid structure. The Nomex spider enhances durability and stability, while the die-cast Euronorm chassis ensures resonance-free operation. These materials, combined with the multilayer voice coil, ensure high efficiency and reliability, especially when reproducing EXTREME KICKBASS. Each component is carefully selected to optimize audio reproduction and meet high acoustic demands.
