The housing depth of 29.7 mm facilitates installation in tighter spaces, as found in many modern cars. Installation is further eased by the weight-saving design of only 0.39 kg, meaning that no compromises in weight need to be made when placing it in hard-to-reach areas.

Wie wird der SPL Show ST 25A Neo.2 in bestehenden Audiosystemen integriert?

When integrating the SPL Show ST 25A Neo.2 from Hertz into an existing audio system, the specific connection requirements should be observed. The tweeter is designed for easy connection and features high-current screw terminals that allow for quick and secure installation. Adequate high-pass filtering at 5 kHz - 12 dB/octave must be set up to fully exploit the performance potential and to avoid distortion at high frequencies. The 4-ohm impedance should also be taken into account when connecting to amplifiers or crossovers.

Wie beeinflusst die FEM-Optimierung den Klang des SPL Show ST 25A Neo.2?

The FEM optimization (Finite Element Method) of the SPL Show ST 25A Neo.2 by Hertz significantly improves sound quality. Through FEM analysis, acoustic deformations in the design of the phase plug and the loading horn are minimized, contributing to the maximization of sound efficiency. This optimization ensures a directed sound wave that reduces the scattering of unwanted frequencies. This results in a clearer, more focused sound image, which plays a crucial role especially at high volumes and in acoustically challenging environments.

Was sind die Vorzüge der Aluminiummembran im SPL Show ST 25A Neo.2?

The SPL Show ST 25A Neo.2 from Hertz benefits from a high-quality aluminum diaphragm. This allows for extreme smoothness and yet strength, resulting in excellent sound pressure. Aluminum has been chosen for its efficiency in sound reproduction at high stability, which means you get thermal resistance that counteracts unwanted distortions at high levels. In addition to acoustic performance, the aluminum diaphragm also contributes to the overall durability of the tweeter, especially in outdoor applications due to the impregnation and anti-UV treatment of the housing.

Welche Bedeutung hat die CCAR-Schwingspule im SPL Show ST 25A Neo.2?

The CCAR voice coil (Copper Clad Aluminium Ribbon) in the SPL Show ST 25A Neo.2 by Hertz is central to its thermal and mechanical performance. By using a copper coating on aluminum, the coil can handle high power loads while remaining lightweight, optimizing overall performance. This combination also allows for excellent heat dissipation, crucial for operation at high volumes over extended periods without the risk of thermal failure. The voice coil also offers flexibility, as it can be easily replaced with spare parts if needed.

Massive 4 inch voice coil!

Massive 4 inch voice coil and ton of power handling, great venting around voice coil, also this vega series has black voice coils. Price/value ratio is very high with vega series.

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 .

X-10 v3 d2

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.
