Frequent questions about SPL Show ST 25K Neo.2

Welche Materialien werden im SPL Show ST 25K Neo.2 von Hertz verwendet?

The SPL Show ST 25K Neo.2 from Hertz uses high-quality materials for optimal performance and durability. The diaphragm is made of aluminum, which is lightweight yet resilient, ensuring maximum sound pressure. The Neodymium N38 H magnet, known for its strong magnetic performance at minimal weight, drives the FEM-optimized tweeter. This combination of materials and design allows for high acoustic efficiency, while the metal grille provides additional protection. Additionally, there is a special waterproof and anti-UV treatment that protects the tweeter from discoloration and weather effects.

Wie beeinflusst der FEM-optimierte Phase-Plug die Leistung des SPL Show ST 25K Neo.2?

The FEM-optimized phase plug of the SPL Show ST 25K Neo.2 plays a central role in the sound performance. Through computer-aided design using Finite Element Method, optimal sound distribution is ensured, leading to a more homogeneous frequency response and more precise sound transmission. This optimization allows the tweeter to operate efficiently across its entire operating range from 3kHz to 20kHz, ensuring high sound accuracy even at high volumes. The phase plug designed in this way significantly contributes to the extraordinary acoustic clarity of the SPL Show ST 25K Neo.2.

Welche Frequenzbereiche deckt der Hertz SPL Show ST 25K Neo.2 ab?

The SPL Show ST 25K Neo.2 from Hertz is designed to cover a wide range of high frequencies. With a working range of 3kHz to 20kHz, it offers excellent performance for the reproduction of high frequencies, which is important for the precision and clarity of the crucial upper sound ranges in audio playback. This wide frequency band is particularly beneficial for users who value crystal-clear highs. Thanks to the neodymium motor and the specialized horn structure, the tweeter can reproduce these frequencies evenly and efficiently, resulting in improved sound quality.

Wie erfolgt die Installation des SPL Show ST 25K Neo.2 in einem Auto?

The installation of the SPL Show ST 25K Neo.2 in a vehicle is quite simple due to its compact dimensions of A: 57 mm, B: 43.5 mm, C: 55.5 mm, and D: 29.7 mm. These dimensions allow for a flexible installation position, ideally choosing a spot in the surface area with good sound propagation and visibility. Inline crossover filtering is supported, which ensures that the tweeter sounds within its optimal frequency range. It is important to position and connect the tweeter in such a way that its full power can be utilized without interference.

Welche Art von Magnet wird im SPL Show ST 25K Neo.2 verwendet?

In the SPL Show ST 25K Neo.2 by Hertz, a Neodymium N38 H magnet is used, known for its exceptional strength and efficiency. This type of magnet is particularly powerful, as it delivers significantly more magnetic energy than conventional ferrite magnets of the same size. This allows for a compact design while maintaining outstanding acoustic performance. The Neodymium magnet also contributes to the weight reduction of the tweeter, positively affecting installation and sound quality. This choice of magnet material achieves a high level of dynamics and precision.

Welche Belastbarkeit hat der Hertz SPL Show ST 25K Neo.2 und wie wird mit hoher Belastung umgegangen?

The SPL Show ST 25K Neo.2 from Hertz has a power handling capacity of 100 Watts Peak, with a recommended high-pass filtering at 5 kHz - 12 dB per octave. This design ensures that only suitable frequencies reach the tweeter, thereby avoiding distortion and damage. This is supported by the CCAR voice coil, which provides thermal and mechanical resilience, significantly reducing the risk of overheating. This combination ensures that the ST 25K Neo.2 can be operated reliably at high volumes without loss of sound quality.

Welche Rolle spielt die Anti-UV- und Wasserdichte-Beschichtung am SPL Show ST 25K Neo.2?

The anti-UV and waterproof coating of the SPL Show ST 25K Neo.2 is crucial for its suitability for outdoor use. This protective layer not only prevents water ingress but also damage from UV radiation, which can lead to fading or material fatigue. Especially for installations in open vehicles or during outdoor operations, protection against weather influences is essential. These treatments ensure the longevity of the tweeter and the reliability of its performance, regardless of the environmental conditions.

Kann der SPL Show ST 25K Neo.2 mit verschiedenen Autosystemen kompatibel sein?

The SPL Show ST 25K Neo.2 offers universal compatibility for many car sound systems due to its impedance of 4 ohms and compact design. Although no specific car brands are mentioned in the description, the provided flexibility allows it to harmonize with a variety of different systems, especially when precise tuning of the crossovers is performed. This makes it particularly valued by tuning professionals who aim for acoustic optimization of their vehicle speakers to achieve the highest sound precision and audio performance.

Wie beeinflussen die Thiele Small Parameter die Leistung des SPL Show ST 25K Neo.2?

The Thiele-Small parameters of the SPL Show ST 25K Neo.2, including Re: 2.9 Ohm, Fs: 3900 Hz, Le: 0.03 mH, and Bl: 2.05 T*m, provide insights into the electrical and mechanical performance of the tweeter. Re represents the DC resistance, affecting power loss due to heating and power efficiency, while Fs indicates the resonance frequency, which is crucial for the design of the enclosure volume. Le measures the voice coil inductance, important for high-frequency adjustments, while Bl describes the drive of the speaker cone, essential for motion accuracy. Together, they significantly determine the sound characteristic.

Welchen Einfluss hat die CCAR-Schwingspule auf die Leistung des SPL Show ST 25K Neo.2?

The CCAR voice coil in the SPL Show ST 25K Neo.2 plays a central role in the safe handling of high power levels. Thanks to its special construction of copper-wound aluminum strips, it achieves excellent thermal conductivity and mechanical stability. This special design allows it to handle high power levels without overheating the moving parts, while also providing high power recovery. Additionally, the CCAR voice coil improves the reliability of the digital signal at high volumes, which is crucial for distortion-free audio playback for music lovers at high volumes.

Massive MiniMonster!

What a Minimonster, 18Liter ported box,tuned to 32hz and plays very loud and even good on lows. Even when i'm underpowering and only giving 350-400watts max. I really love this 6,5 monster, also the aluminium basket is very strong and solid and has great venting for the voice coil. Having rubber surround and carbon fiber cone just makes this even more indestructible

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.
