Frequently Asked Questions about SPL Show ST 35K Neo


What performance features does the SPL Show ST 35K Neo Tweeter offer?

The Hertz SPL Show ST 35K Neo Tweeter impresses with its powerful Neodym-N38 H magnet, providing an impressive maximum load capacity of 120 watts (peak). It is optimized for a frequency response of 2 kHz to 20 kHz and features high efficiency with a sound pressure level of 109 dB. The ultra-light aluminum diaphragm contributes to maximizing the sound pressure level, while the FEM-optimized phase plugs and horn ensure excellent thermal and mechanical capabilities. Additionally, the use of a CCAR voice coil enhances performance.

How does the neodymium material of the SPL Show ST 35K Neo contribute to performance?

The Hertz SPL Show ST 35K Neo uses a Neodym-N38 H magnet in its construction. Neodymium is known for its strong magnetic force in a compact size, allowing the Tweeter to deliver impressive performance even at a small size. This property is particularly important for producing high volumes and detailed sound reproduction. Furthermore, the neodymium material improves thermal performance, as the magnets operate more efficiently and generate less heat.

What distinguishes the design of the driver and horn in the SPL Show ST 35K Neo?

In the Hertz SPL Show ST 35K Neo, the driver and horn design have been optimized using the finite element method (FEM). This method allows for precise prediction and adjustment of vibroacoustic properties, leading to an optimized phase response and improved sound quality. The thoughtful design maximizes sound pressure, enhances the directivity of the Tweeter, and ensures consistent sound dispersion. This is ideal for use in demanding audio applications where precision is essential.

How does the aluminum diaphragm contribute to the sound quality of the SPL Show ST 35K Neo?

The aluminum diaphragm of the SPL Show ST 35K Neo by Hertz is ultra-lightweight and optimized for maximum efficiency, resulting in a high sound pressure level. Aluminum provides an ideal combination of stiffness and low weight, minimizing resonances and enabling precise sound reproduction in the high frequencies. This reduces distortion and ensures clear, brilliant highs. Especially if you enjoy listening to music at high volumes, you will benefit from the clear and detailed reproduction of this design.

What measures for heat dissipation does the SPL Show ST 35K Neo offer?

The SPL Show ST 35K Neo is equipped with an aluminum back cover that ensures efficient heat dissipation. This design reduces the thermal stress on the components and prolongs the lifespan of the tweeter by preventing overheating. The choice of aluminum helps to quickly dissipate the generated heat, ensuring stable sound reproduction even under maximum load. This is particularly important during longer listening sessions or at high volume.

What crossover is used in the SPL Show ST 35K Neo?

In the 'Kit' version of the SPL Show ST 35K Neo by Hertz, an inline crossover filter is integrated. This high-pass filter operates at a coefficient of 4 kHz with a slope of 12 dB per octave. This configuration ensures that the tweeter only receives the frequencies intended for it, minimizing distortion and optimizing sound quality. A well-designed crossover filter is crucial for maximizing the performance and longevity of the tweeter.

What are the dimensions of the SPL Show ST 35K Neo and how do they affect installation?

The SPL Show ST 35K Neo tweeter has a compact size with the dimensions: diameter 46 mm, total height 69 mm, depth 65.7 mm, and mounting flange 33.3 mm. These measurements allow for flexible installation in various vehicle models. Its compact design enables the tweeter to be positioned in tighter installation spaces, making it a versatile choice for modifications and upgrades to existing audio systems without overwhelming the available space.

What is the compatibility of the SPL Show ST 35K Neo with common car brands?

The SPL Show ST 35K Neo from Hertz can be integrated into many car systems due to its versatile dimensions. With a mounting flange of 33.3 mm and a shallow installation depth, this tweeter can be installed in numerous vehicle brands and models. Although no specific car brand is mentioned in the product description, it can be flexibly used in most audio applications, allowing for adjustments to specific car configurations.

How is thermal and mechanical stability ensured in the SPL Show ST 35K Neo?

The SPL Show ST 35K Neo uses a CCAR voice coil that provides outstanding thermal and mechanical stability. The copper-clad aluminum tube construction of this voice coil contributes to efficient heat distribution and increased load capacity under practical conditions. The neodymium magnet also helps reduce heat buildup, leading to better performance and longevity of the tweeter overall. These technical details make it ideal for demanding audio applications.

What additional features does the 'Kit' version of the SPL Show ST 35K Neo offer?

The 'Kit' version of the SPL Show ST 35K Neo from Hertz offers additional features such as a metal grille that protects the tweeter from physical damage and contributes to the aesthetic integration into the car's interior design. The included inline crossover significantly improves sound separation, while the anti-UV treatment extends material durability for outdoor use. These extra features enhance the versatility of the tweeter, making it both robust and optimal for outdoor applications.
