Frequently Asked Questions about HGS-2521

What are the technical features of the Black Hydra HGS-2521?

The Black Hydra HGS-2521 Subwoofer combines a strong motor structure with a lightweight yet robust cellulose composite membrane. The powerful cast frame ensures extremely stable sound reproduction without unwanted vibrations. An important feature of the HGS-2521 is the black aluminum frame of the voice coil, which ensures optimized heat dissipation and effectively reduces thermal compression. The high-quality ferrite magnet guarantees consistent performance parameters. With an RMS power of 230 W and a maximum power of 450 W, the Subwoofer offers impressive performance in compact dimensions.

What are the dimensions of the HGS-2521 and where can it be installed?

The installation depth of the Black Hydra HGS-2521 is 135.7 mm, the outer diameter measures 255 mm, and the cutout size is 241.0 mm. Thanks to these compact dimensions, the Subwoofer is ideal for installation in classic and stealth acoustic enclosures, especially in limited space. Since the HGS-2521 operates in compact enclosures, it is well-suited for a variety of vehicle installations.

What are the performance specifications of the Black Hydra HGS-2521?

The Black Hydra HGS-2521 boasts impressive performance specifications: an RMS power of 230 watts ensures consistently high sound quality, while the maximum power consumption is 450 watts. The impedance is 4 ohms, making the Subwoofer an ideal complement for many amplifier configurations. With a sound pressure of 84.15 dB, the Subwoofer provides excellent music reproduction. The optimal amplifier power is between 300 and 600 watts.

How efficient is the heat dissipation of the HGS-2521?

The Black Hydra HGS-2521 utilizes a black aluminum frame for the voice coil, which not only provides a robust structure but also enhances heat dissipation. This aspect efficiently prevents thermal compression that can occur during prolonged use. Thus, the reliability of the Subwoofer is increased, making it ideal for longer listening sessions even at high volumes.

What is the membrane structure of the Black Hydra HGS-2521 made of?

The membrane of the Black Hydra HGS-2521 is made from a stiff cellulose composite. This structure offers an ideal balance between weight and stability, which in turn ensures excellent sound performance. The lightweight construction allows for quick and precise movement response, while the robustness minimizes distortion at varying volumes. Combined with the 2.00-inch voice coil, the membrane provides outstanding sound fidelity.

How does the HGS-2521 affect sound quality at high volumes?

The Black Hydra HGS-2521 was designed for linear diaphragm movement up to a stroke of 24 mm to achieve consistently clear sound reproduction at high volumes. The rubber surround and the centering spider complement the powerful motor to minimize distortion even under extreme operating conditions. Its excellent feature that prevents mechanical damage makes the HGS-2521 particularly robust and reliable for high volume playback.

How does the HGS-2521 fit into different acoustic enclosures?

The Black Hydra HGS-2521 is ideally suited for use in compact acoustic enclosures due to its design. Its ability to deliver optimal performance in stealth enclosures makes it perfect for installations where space is limited. Its installation depth of 135.7 mm and cutout diameter of 241.0 mm allow for flexible adaptation to various types of enclosures, while the total weight of 6.50 kg promotes easy handling.

What role does the ferrite magnet of the HGS-2521 play?

The Black Hydra HGS-2521 is equipped with a ferrite magnet that represents the highest quality class. This magnet is the heart of the motor system and ensures excellent stability and repeatability of the sound characteristics of the Subwoofer. The robust magnetic field directly affects the movement dynamics of the diaphragm and enables precise and powerful sound results. The magnet guarantees long-lasting performance of the Subwoofer due to its excellent quality.

Which technical parameters influence the sound reproduction of the HGS-2521?

Various technical parameters define the sound reproduction of the Black Hydra HGS-2521: The frequency response starts at Fs 30.78 Hz, while the Qts value of 0.31 indicates excellent efficiency. The BL value of 17.64 demonstrates the strength of the magnetic field acting on the voice coil. Furthermore, the Vas value of 23.00 L and the impedance of 4 Ohms contribute to the overall performance. These parameters are crucial to ensure precise and powerful audio output, making the Black Hydra HGS-2521 a powerful Subwoofer.

How does the rubber surround improve the performance of the HGS-2521?

The rubber surround of the Black Hydra HGS-2521 plays a central role in the performance of the Subwoofer. It allows for flexible yet controlled diaphragm movement, significantly minimizing resonances and distortions. Its composition enables stable sound reproduction even at high volumes, while simultaneously protecting the frame and components of the speaker from mechanical damage. The interaction between the rubber surround and motor structure maximizes both the sound performance and the lifespan of the Subwoofer.

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.
