Frequently Asked Questions about Helon HS 25 EVO 2

What are the special features of the Helon HS 25 EVO 2?

The Helon HS 25 EVO 2 from Audio System is a Dome Tweeter with a 25 mm textile diaphragm equipped with a neodymium magnet. Key technical features include ferrofluid cooling to enhance thermal resilience and flexible installation options thanks to its compact design. The included protective grilles and mounting brackets facilitate secure installation, while the impedance of 4 ohms and the resonance frequency Fs of 960 Hz ensure compatibility with various audio systems. The innovative design allows for a mounting depth of 16 mm with bracket and 21 mm without bracket including grille.

What are the dimensions of the Helon HS 25 EVO 2 Tweeter?

The Helon HS 25 EVO 2 offers variable dimensions specifically tailored for compatibility and installation in different environments. The outer diameter is 53.5 mm with bracket and 44 mm without bracket. The mounting depth is 16 mm with bracket and 21 mm without bracket with grille, depending on the use of the bracket and protective grille. The installation measurement is 47.5 mm with bracket and 44 mm without bracket. This flexibility makes it easier to install in original tweeter openings or to attach to the A-pillar.

For which applications is the Helon HS 25 EVO 2 ideally suited?

The Helon HS 25 EVO 2 is ideal for users who desire excellent high-frequency reproduction in their audio system. With a frequency range starting at 960 Hz, this tweeter is optimally suited for use in demanding car hi-fi systems, with ferrofluid cooling ensuring sustained performance at high sound pressure levels. The high flexibility in mounting depths and dimensions allows for integration into almost any vehicle or home installation. Especially in tight spaces behind the A-pillar or in narrow tweeter openings, the compact neodymium tweeter shows its strength.

How do I install the Helon HS 25 EVO 2 in my vehicle?

The installation of the Helon HS 25 EVO 2 requires careful attention to dimensions and installation options. First, you should choose the placement: either in original tweeter openings or with the supplied capsules at the A-pillar. Ensure there is enough space for the installation depth – 16 mm with holder or 21 mm without holder with grille. Use the cutout or the provided mounting material and secure the tweeter properly. Make sure the connection to your Audio System is made correctly and without risk of short circuit – the impedance is 4 Ohms.

What sound characteristics does the Helon HS 25 EVO 2 offer?

The Helon HS 25 EVO 2 delivers impressive sound precision, supported by the 25 mm fabric diaphragm and the powerful neodymium magnet. The technical design ensures clear and distortion-free reproduction of high frequencies, while the frequency range starting at 960 Hz allows for seamless integration into well-tuned car Hi-Fi systems. Users report a significant improvement in fine resolution in the high-frequency range, enhancing the stereo stage. The ferrofluid cooling also contributes to the consistency of this performance at higher volumes.

What materials are used in the Helon HS 25 EVO 2?

The Helon HS 25 EVO 2 relies on a high-quality selection of materials to ensure maximum performance. The 25 mm fabric diaphragm provides a lightweight yet rigid structure that ensures accurate sound reproduction. The use of a powerful neodymium magnet also guarantees high efficiency and enables the compact dimensions of the tweeter. Additionally, the included grille protects the sensitive components, while the ferrofluid cooling ensures long-term thermal stability. The materials significantly contribute to the quality and durability of the tweeter.

What advantages does ferrofluid cooling offer in the Helon HS 25 EVO 2?

The ferrofluid cooling in the Helon HS 25 EVO 2 plays a crucial role in thermal stability and enhances performance. It ensures that the voice coil is efficiently cooled, which counteracts overheating even at high volumes. This not only improves heat dissipation but also reduces power loss and prevents distortion at extreme levels. Particularly, if you enjoy listening to music loudly and want to maintain sound fidelity over extended periods, the ferrofluid cooling proves essential for the long-term functionality of the Tweeter.

How should the Helon HS 25 EVO 2 be positioned in the room?

When positioning the Helon HS 25 EVO 2 in the room, its compact and flexible design is a significant advantage. You can install it both behind original Tweeter openings and freestanding with the mounting brackets. Ensure that the positioning is as close to the listening position as possible to achieve the best sound radiation and a wide stereo stage. The protective grilles provide additional protection when the Tweeter is placed freely. The installation options allow you to mount the Tweeter easily on ceilings, walls, or in vehicle interiors.

Are there specific compatibility aspects for the Helon HS 25 EVO 2?

The Helon HS 25 EVO 2 is a universally applicable Tweeter and is explicitly not limited to specific car brands or models. However, you must ensure that the installation dimensions harmoniously integrate into the designated openings of your vehicle. With a standardized impedance of 4 ohms, this Tweeter is highly compatible with most commercially available amplifiers and Audio Systems. The adaptable dimensions of 53.5 mm outer diameter with bracket and 44 mm without bracket allow for installation even in tight spaces.

What frequency range does the Helon HS 25 EVO 2 cover?

The Helon HS 25 EVO 2 is specifically designed to cover a wide range of high frequencies, starting at a resonance frequency of 960 Hz. This technical specification allows the Tweeter to be seamlessly integrated into existing Audio Systems to create a cleaner and fuller soundstage. The precise tuning enables the extraction of all nuances and details typical for the high-frequency range, which is particularly beneficial when reproducing high-quality audio content. The wide frequency coverage ensures that no critical frequencies are lost, significantly enhancing music and sound quality.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.
