The Subwoofer also features a dual magnet with a total weight of 2 x 24 oz., contributing to its high performance. This combination of features ensures that the Signum SXT8D2 operates efficiently in both low and maximum load ranges.

What are the Thiele-Small parameters of the Signum SXT8D2 Subwoofer?

The Thiele-Small parameters of the Signum SXT8D2 from ESX are crucial for understanding its performance in different enclosure types. The resonance frequency (Fs) is 34 Hz, indicating that this Subwoofer is optimized for bass reproduction in the low frequency range. The total quality factor (Qts) is 0.56, making it flexible for use in sealed and vented enclosures. The equivalent air volume (VAS) is 19 liters. These parameters assist in the precise design of enclosures for the Signum SXT8D2 to optimize bass performance and sound quality.

What are the dimensions of the Signum SXT8D2 Subwoofer?

The Signum SXT8D2 from ESX has a cutout diameter of 182 mm and a mounting depth of 123 mm, making it compatible with many standard enclosures. These dimensions are ideal for an 8-inch (20 cm) Subwoofer design that offers a good balance between ease of installation and performance. With a maximum cone excursion (X-Max) of +/- 19 mm, it can deliver impressive bass without reaching mechanical limits. The robust construction with a stable steel basket further supports easy and precise installation. These specifications ensure easy integration into various systems.

How does the vented pole core of the Signum SXT8D2 work?

The ventilated pole core of the Signum SXT8D2 Subwoofer from ESX plays a crucial role in cooling the voice coil during intense power phases. This ventilation quickly dissipates excessive heat, counteracting thermal stress and enhancing the longevity of the voice coil. This feature is particularly advantageous when the Subwoofer is operated near its maximum power limit. It minimizes distortion and ensures that audio playback remains clear and precise even at high levels. The integration of the ventilated pole core highlights the engineering behind this powerful audio component.

What makes the crafted paper membrane of the Signum SXT8D2 special?

The crafted paper membrane of the Signum SXT8D2 Subwoofer from ESX significantly contributes to sound quality and structural stability. This type of membrane is known for its excellent damping and low distortion, resulting in a clean, natural sound profile that excels particularly in the bass range. The lightweight construction of the paper membrane also improves sensitivity and dynamics while minimizing resonance characteristics. This ensures optimal response behavior for deep bass, which is especially beneficial for music genres with a strong bass character. The crafted structure increases mechanical stability, allowing the membrane to maintain its shape even at intense bass frequencies.

How does the Signum SXT8D2 perform in different enclosure types?

The Signum SXT8D2 Subwoofer from ESX finds excellent application in various enclosure types, particularly in sealed and vented designs. Thanks to the Thiele-Small parameters, especially the Qts value of 0.56, the Subwoofer is suitable for both smaller sealed enclosures that deliver precise bass and vented boxes that provide higher sound pressure. With a VAS of 19 liters, a well-planned enclosure can be volume-optimized to maximize bass performance. Particularly for sound-conscious installations in vehicles, the Signum SXT8D2 proves to be versatile and offers a balanced, powerful bass.

How does the 50 mm voice coil affect the sound quality of the Signum SXT8D2?

The 50 mm voice coil of the Signum SXT8D2 from ESX is a central element that significantly determines its sound quality. With a winding height of 27 mm, this voice coil allows for high mechanical load capacity and precise control of the diaphragm movement, leading to improved reproduction even with complex bass sequences. The larger winding surface increases heat dissipation, reducing distortion at high volume levels and ensuring consistent performance. This technical design contributes to the robust acoustic performance that is particularly attractive to enthusiasts of detailed and powerful bass.

What does the impedance of 2+2 Ω mean for the Signum SXT8D2?

The impedance of 2+2 Ω in the Signum SXT8D2 Subwoofer from ESX offers significant flexibility for integration into audio systems. This dual voice coil (DVC) configuration allows the subwoofer to be wired to different impedance values to achieve optimal compatibility with various amplifiers. For example, it can be operated in both a 1 Ω and a 4 Ω configuration, depending on the wiring of the coils. This facilitates adaptation to different amplifier powers and types, optimizing system performance through precise impedance tuning, resulting in more efficient operation and improved sound quality.

What role does the dual magnet play in the Signum SXT8D2?

The dual magnet of the Signum SXT8D2 from ESX, consisting of two 24 oz. (total weight 1.3 kg), is an essential component for the powerful bass reproduction of this subwoofer. This magnet configuration creates a strong magnetic field necessary to move the large voice coil with sufficient force. The increased magnetic strength enhances the subwoofer's response time and ensures precise and dynamic bass performance. This is particularly important for music genres that require fast and powerful bass reproduction. Thus, the dual magnet contributes to the high efficiency and clarity that characterize the Signum SXT8D2.

How compatible is the Signum SXT8D2 in a car?

The Signum SXT8D2 Subwoofer from ESX, with a mounting depth of 123 mm and a cutout diameter of 182 mm, is suitable for integration into numerous standard enclosures in vehicles. These compact dimensions allow for flexible installation in common enclosure types and vehicle models that accommodate 8-inch subwoofers. Proper enclosure construction is crucial for optimal performance, with the VAS value of 19 liters being taken into account. This enables the subwoofer to fit more easily into various audio systems, making it particularly attractive for car audio enthusiasts seeking powerful bass in their vehicles.

Top für den Preis !!!

Hören sich gut an!!! hätte ich nicht gedacht in der Preisklasse, vor allem der Pegel hab sie mit paar Axton Hochtönern verbaut und einem Kicker sub im Kofferraum und paar Rainbow Endstufen sauberer lauter klang bin sehr zufrieden mit dem Produkt. Langzeit noch keine Erfahrung da erst zwei Wochen verbaut

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
