Frequently Asked Questions about Signum SX840

What power does the Signum SX840 from ESX offer?

The Signum SX840 from ESX delivers remarkable performance with 300 watts RMS and a maximum power of 600 watts. This high power capability enables a powerful, deep bass that supports high-quality sound reproduction. The rated power ensures dynamic movement, while the Subwoofer reaches its maximum power under full load. Especially if you enjoy listening to music with intense bass, you will appreciate the advanced technology built into this Subwoofer. The thoughtful design ensures long-term stable performance.

What is the installation depth of the Signum SX840 Subwoofer?

The Signum SX840 Subwoofer has an installation depth of 114 mm. This relatively shallow installation depth allows for versatile installation in different vehicle types and enclosure styles without sacrificing bass performance. The compact design makes the Subwoofer ideal for tight spaces. The installation depth plays a crucial role in implementation in vehicles, especially if you are making your own audio configurations to achieve the best sound in your car.

What materials are used in the Signum SX840?

The Signum SX840 uses high-quality materials such as a sturdy aluminum basket and a single Nomex spider cone. The aluminum basket provides the necessary rigidity and stability to minimize vibrations, while the Nomex spider cone ensures additional durability. Together with a ventilated pole piece, the efficiency of the Subwoofer is maximized by dissipating heat during intense operating phases. This combination not only improves sound quality but also contributes to the longevity of the Subwoofer.

What impedance does the Signum SX840 from ESX have?

The Signum SX840 Subwoofer from ESX has an impedance of 4 Ω. This impedance is commonly found in many car audio components and ensures that the subwoofer is easily supported by a variety of amplifiers. With proper impedance matching, you can optimize the efficiency of power output and achieve clearer, distortion-free bass sound. When planning your car audio system, it is important to pay attention to this electrical specification.

What voice coil does the Signum SX840 use?

The Signum SX840 is equipped with a 50 mm long voice coil that has a winding height of 15 mm. This sizing allows for effective control of the diaphragm movement, enabling the subwoofer to produce precise bass without distortion. The voice coil is essential for sound quality as it translates the electromagnetic signal into mechanical movement. Using a long voice coil allows for a longer linear stroke, which is particularly beneficial in low-frequency ranges.

What role does the dual magnet play in the Signum SX840?

The Signum SX840 is equipped with a dual magnet of 2 x 1.3 kg. This dual magnet serves to provide the magnetic field for the voice coil and ensures higher efficiency of the subwoofer in converting electrical signals into acoustic energy. The magnet not only improves sensitivity and sound pressure level but also increases the subwoofer's load capacity. The combined magnet generates a stronger driving force, resulting in a more dynamic and louder bass.

What are the dimensions of the Signum SX840 Subwoofer?

The Signum SX840 Subwoofer has a diameter of 20 cm (8 inches) and a mounting diameter of 189 mm. This compact size allows for flexible installation in various enclosures and vehicle types. The precise measurements are crucial during installation to ensure a perfect fit and avoid resonances. The size of the subwoofer significantly influences the sound character, with the 20 cm being optimal for powerful bass without compromising playback quality. The dimensions facilitate adaptation to individual requirements.

How does the ventilated pole core improve the performance of the Signum SX840?

The ventilated pole core of the Signum SX840 significantly enhances heat dissipation by allowing cool air to circulate through the core center. This process reduces thermal stress on the voice coil, especially during intense use, preventing overheating and increasing reliability. Effective cooling is essential to minimize distortion and maintain consistent audio performance. Especially during long listening sessions, you benefit from the consistent sound quality achieved through the enhanced air circulation design.

Is the Signum SX840 suitable for specific car brands?

The Signum SX840 fits a variety of vehicle types due to its dimensions and a mounting depth of 114 mm. Although there are no specific brand model requirements in the description, the universal design allows this Subwoofer to be integrated into many common car enclosures, provided there is enough space. During installation, care must be taken to ensure that all electrical connections are made cleanly to achieve optimal performance. For the car audio enthusiast, the Subwoofer design offers a variety of installation options.

How does X-Max affect the sound quality of the Signum SX840?

The Signum SX840 has an X-Max of +/- 13 mm, which indicates the maximum linear excursion before the Subwoofer begins to distort. X-Max is crucial for reproducing particularly low frequencies, as it shows how far the diaphragm can move in both directions to produce deep bass notes. The larger the X-Max value, the more powerful and uncolored the bass can be produced. This specification ensures that the Subwoofer produces clear, distortion-free tones even at high volumes, which can significantly enhance your listening experience.

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.
