Frequently Asked Questions about Apocalypse DВ-3.5K 15"

How big is the Apocalypse DB-3.5K 15" Subwoofer?

The Apocalypse DB-3.5K 15" from Deaf Bonce has a diameter of 15 inches, which is 38 cm. This size is specifically designed for deep and powerful bass reproduction, suitable for systems that have high power requirements. The construction with a pressed paper cone combined with a robust aluminum basket structure ensures that the subwoofer delivers both pressure and precision. Size plays a crucial role, especially at frequencies in the range of 20 to 80 Hz, where the subwoofer performs optimally. As a bass enthusiast, you can expect impressive bass performance from this format.

What power does the Apocalypse DB-3.5K 15" Subwoofer offer?

The Apocalypse DB-3.5K 15" offers an impressive RMS power of 3,500 watts and a maximum power handling of 7,000 watts. These power specifications make it ideal for use in performance-oriented car audio systems that need to sound clear and precise even at high volumes. Thanks to the high-quality ferrite magnets and a robust voice coil with a diameter of 3 inches, clear and distortion-free playback is ensured even at the highest levels. Therefore, the subwoofer is particularly suitable for displays and showcases where maximum audio performance is a must.

What materials are used in the construction of the Apocalypse DB-3.5K 15"?

The subwoofer uses high-quality materials such as a pressed paper cone, known for its lightness, which, in combination with a foam surround material, provides high efficiency in bass reproduction. The aluminum basket ensures increased structural integrity, while the ferrite magnet provides strong drive. This combination of materials ensures that the subwoofer is both durable and powerful, which is particularly advantageous in high-performance environments like custom car audio installations. This choice of materials results in an overall system efficiency that provides an exceptional listening experience.

How does the maximum linear excursion affect the sound quality of the Apocalypse DB-3.5K 15"?

The maximum linear excursion of a Subwoofer is an important factor for sound quality. The Apocalypse DB-3.5K 15" has a maximum linear excursion (Xmax) of 25 mm, which means that the speaker cone can handle deep frequencies with high amplitude without distortion. Especially if you enjoy listening to music loudly, this excursion ensures that the bass remains powerful and precise, even at high volumes. This high Xmax value allows the Subwoofer to deliver dynamic and controlled bass reproduction, which is particularly important in environments where impactful and clear low tones are essential.

What Thiele-Small parameters does the Apocalypse DB-3.5K 15" D1 have?

For the DB-3.5K 15" D1 model with Dual 1 Ohm impedance, the Thiele-Small parameters are as follows: The impedance is 1 + 1 Ohm, the DC resistance (Re) is 0.7 + 0.7 Ohm. The sensitivity (SPL) of the Subwoofer is 87.6 dB, while the resonance frequency (Fs) is at 30 Hz. The equivalent volume (Vas) is 60.6 liters, and the total quality factor (Qts) is 0.51. Additionally, the Subwoofer has a drive factor (BL) of 18. These precise parameters are crucial for tuning and integration into professional car audio applications.

How do I install the Apocalypse DB-3.5K 15" correctly?

When installing the Apocalypse DB-3.5K 15", proper placement is crucial, especially to fully utilize the Subwoofer's performance. Due to its dimensions of 15 inches, it is important to ensure that there is enough space in the enclosure to avoid restricting the diaphragm movements. A stable anchoring is important to minimize vibrations and thus maximize sound quality. The aluminum basket of the Subwoofer allows for a lightweight and secure installation. Integration should ideally be done with a specific amplifier that meets the requirements of the RMS power of 3,500 watts.

What are the voice coil dimensions of the Apocalypse DB-3.5K 15"?

The Apocalypse DB-3.5K 15" features a voice coil with a diameter of 3 inches, allowing for efficient conversion of electrical energy into acoustic power. The voice coil is made of PIAL, a flat wire aluminum that is both lightweight and resistant to temperature changes. This combination leads to increased heat dissipation and minimizes distortion that could arise from thermal stress. The design of the voice coil allows for the efficient use of the RMS power of 3,500 watts, which is reflected in the powerful bass reproduction.

What frequency ranges does the Apocalypse DB-3.5K 15" cover?

The frequency range of the Apocalypse DB-3.5K 15" lies between 20 and 80 Hz. This frequency range is specifically designed for the reproduction of deep, powerful bass. This range is perfect for the needs of modern bass enthusiasts looking for a strong and precise bass. By using high-quality materials such as the pressed paper diaphragm in combination with the efficient ferrite magnet, accurate bass reproduction is ensured even at extremely low frequencies. The deep-reaching bass is ideal for car audio applications that aim for maximum volume and sound quality.

What role does the drive factor (BL) play in the Apocalypse DB-3.5K 15"?

The drive factor, indicated as BL, is a crucial parameter in the development of subwoofers like the Apocalypse DB-3.5K 15". In the case of the DB-3.5K 15" D1, the BL value is 18, while for the D2 model it is 25.6. The BL value is a measure of the electromagnetic driving force of the voice coil within the speaker system's magnetic field. A higher BL value means stronger control and more efficient conversion of electrical signals into mechanical movement. This affects the dynamics of sound reproduction, especially at low frequencies, and ensures a clear and powerful sound quality.

How important are the materials for the surrounds and diaphragms in the Apocalypse DB-3.5K 15"?

In the Apocalypse DB-3.5K 15", the choice of materials for the surrounds and diaphragms is of great importance for performance. The surrounds are made of foam, which is known for its flexibility and damping properties. These ensure that the diaphragm movements occur in a controlled manner and minimize resonances. The diaphragm itself is made of pressed paper, a material that is often used for custom subwoofers due to its lightness and stiffness. These properties guarantee that the subwoofer accurately reproduces the desired low frequencies while maintaining high energy efficiency.
