Frequently Asked Questions about Helon H 12 EVO


What power does the Helon H 12 EVO Subwoofer offer?

The Helon H 12 EVO from Audio System delivers an impressive performance with 2x 1300/1100 Watts RMS, meaning it can consistently handle 1300 Watts on each of its two voice coil channels. In peak performance, this Subwoofer reaches a maximum power of 12500 Watts at 60 Hz, achieving a very high sound pressure level. For enthusiasts who love bass, this power provides exceptional low-frequency dynamics and presence across various music genres.

What are the dimensions of the Audio System Helon H 12 EVO?

The Helon H 12 EVO Subwoofer features a diameter of 12 inches or 300 mm, allowing it to produce sufficient bass volume even in more compact enclosures. The installation depth is 215 mm, enabling it to be installed in a variety of enclosure types. The mounting diameter is 290 mm, while the outer diameter measures 325 mm. These dimensions allow for flexible integration into many audio systems.

How is the Helon H 12 EVO constructed?

The Helon H 12 EVO Subwoofer offers a sophisticated construction with a flow-optimized cast basket that ensures stability and durability. It features a highly stable KPC paper cone that contributes to sound quality. The double-stitched foam surround allows for high flexibility and power handling. The woven 2-fold silver wires provide excellent electrical connectivity. A HEM magnet system ensures efficient magnetic flow, while the improved T-joke and pole-plate design optimize mechanical load capacity.

What impedance does the Helon H 12 EVO Subwoofer offer?

The Helon H 12 EVO is equipped with an impedance of 2x 2 Ohms, making it versatile in different amplifier setups. This configuration allows the Subwoofer to be operated flexibly in parallel or series connections, depending on the requirements for overall speaker impedance. With this dual impedance configuration, optimal performance and compatibility with a variety of amplifier systems can be achieved.

How does the ventilation system of the Helon H 12 EVO work?

The Helon H 12 EVO features a 33-fold ventilation system that ensures efficient cooling of the entire Subwoofer. This high-frequency ventilation is crucial for effectively dissipating heat from the internal components and the voice coil. Especially under high load, such as during gigs or in club applications, this system prevents heat buildup and heat loss, leading to higher performance and longevity of the Subwoofer.

What voice coil does the Helon H 12 EVO use?

The Helon H 12 EVO is equipped with a 3-inch flat wire dual voice coil, manufactured in the USA. This voice coil allows the Subwoofer to produce high power levels with low distortion. Flat wire provides greater efficiency because it allows more turns in the same area than round wire. This design improves heat dissipation while maximizing power handling and sound pressure level.

What is an SPL Woofer and how does the Helon H 12 EVO qualify as one?

An SPL Woofer (Sound Pressure Level) is designed to deliver maximum volume and sound pressure levels. The Helon H 12 EVO qualifies as an SPL Power-Subwoofer due to its impressive performance of 2x 1300/1100 Watts RMS and a peak power of 12500 Watts. This design enables it to meet the high demands of sound competitions where maximum volume at low frequencies is crucial. SPL enthusiasts will be particularly impressed by the dynamic bass.

How should the Helon H 12 EVO be installed in the vehicle?

When installing the Helon H 12 EVO in the vehicle, dimensions and installation depth are critical. With an installation depth of 215 mm, it is essential to ensure there is enough space. The installation diameter of 290 mm and an outer diameter of 325 mm require precise cutout size in the speaker enclosure. A stable mounting is necessary to minimize vibrations and resonances. The placement location should be carefully selected to achieve optimal bass resonances in the vehicle.

What materials characterize the diaphragm of the Helon H 12 EVO?

The diaphragm of the Helon H 12 EVO is made from an ultra-thin KPC paper diaphragm, specifically designed to provide advanced sound reproduction and high stability. This diaphragm is known for its ability to reproduce the moving air without deformation or unpleasant resonances. Additionally, the diaphragm is supported by a highly flexible and double-stitched foam surround. This combination ensures that the reproduction is precise yet powerful, making it perfect for SPL applications.

What is the advantage of the Carbon Dustcap on the Helon H 12 EVO?

The Pure Carbon Dustcap of the Helon H 12 EVO offers several advantages, including increased stability and improved acoustic properties. By using carbon as a material, the mass of the dustcap is minimized without compromising structural integrity, leading to faster response and reduced distortion. Furthermore, it ensures that maximum loads are evenly distributed across the diaphragm, contributing to the increased lifespan of the Subwoofer. These features make it particularly efficient in SPL setups.
