Frequently Asked Questions about Apocalypse DВ-5.5K 15"

What materials are used in the Apocalypse DB-5.5K 15"?

The Apocalypse DB-5.5K 15" from Deaf Bonce is made from various high-quality materials. The diaphragm is constructed from a carbon composite sandwich, which provides excellent stiffness and low weight. The surround is made of foam, offering optimal flexibility. The aluminum basket provides stability, and the use of a ferrite magnet ensures strong magnetic performance. This combination results in a durable and performance-oriented design that is ideal for demanding audio applications.

How much wattage does the Apocalypse DB-5.5K 15" subwoofer deliver?

The Apocalypse DB-5.5K 15" from Deaf Bonce features impressive performance capabilities. The RMS power is 5,500 watts, meaning this subwoofer provides sufficient continuous power for most application scenarios. The maximum power, or MAX Power, reaches 11,000 watts, which is particularly important in extreme situations like competitions. These power ratings allow the subwoofer to remain clear and precise even during the loudest bass sequences without causing distortion.

What technical specifications characterize the frequency range of the Deaf Bonce Apocalypse DB-5.5K 15"?

The frequency range of the Apocalypse DB-5.5K 15" from Deaf Bonce is between 20 to 80 Hz. This range allows the subwoofer to accurately reproduce deep bass tones, providing a complete and intense sound experience. Especially when playing bass-intensive music genres, the subwoofer can fully showcase its strengths. The maximum linear excursion (Xmax) is specified at 22.5 mm, which allows for strong diaphragm displacement without sound distortion. The specific data is tailored to ensure deep and full-bodied bass reproduction.

What are the Thiele-Small parameters for the Apocalypse DB-5.5K 15"?

The Apocalypse DB-5.5K 15" comes in two versions with different Thiele-Small parameters. The D1 version (Dual 1 Ohm) offers an impedance of 1 + 1 Ohm, a resonance frequency (Fs) of 30 Hz, and a drive factor (BL) of 26. The D2 (Dual 2 Ohm) variant has an impedance of 2 + 2 Ohm, a resonance frequency of 31 Hz, and a drive factor of 33.8. Both variants have a DC resistance (Re) of 0.7 + 0.7 Ohm respectively 1.4 + 1.4 Ohm. These parameters are crucial for fine-tuning the Subwoofer in different enclosures and acoustic environments.

How is the voice coil of the Deaf Bonce Apocalypse DB-5.5K 15" designed?

The voice coil of the Apocalypse DB-5.5K 15" from Deaf Bonce has a diameter of 4.5 inches, which is above average for Subwoofers of this size. The voice coil wire is made of PIAL, a flat wire aluminum known for its excellent conductivity and low mass. This design allows for excellent heat distribution, increasing the longevity of the Subwoofer and enabling strong bass output without overheating. The large voice coil also provides higher power handling and more precise control over the diaphragm movement.

What impedances does the Apocalypse DB-5.5K 15" Subwoofer offer?

The Apocalypse DB-5.5K 15" Subwoofer from Deaf Bonce is available in two impedance options: Dual 1 Ohm (D1) and Dual 2 Ohm (D2). In the D1 model, the impedance is at 1 + 1 Ohm, while the D2 variant offers 2 + 2 Ohm. This means that the Subwoofer can be wired in different configurations for amplifiers to achieve optimal performance. The adaptability regarding impedance is crucial for integration into existing audio systems and allows for flexible adjustment to different amplifier outputs.

What are the dimensions of the Apocalypse DB-5.5K 15" and how does that affect compatibility with vehicles?

The Apocalypse DB-5.5K 15" from Deaf Bonce has a size of 15 inches (38 cm). This specific dimension should be considered when planning the installation in the vehicle. Especially in vehicles with smaller trunks, the space requirement can pose a challenge. It is important to check the installation situation in the vehicle, as the entire installation space for enclosures and possible amplifier arrangements must be taken into account. Due to the size of the Subwoofer, sufficient space for diaphragm excursion is required to avoid sound distortion.

What does the maximum linear excursion (Xmax) of the Deaf Bonce Apocalypse DB-5.5K 15" mean?

The maximum linear excursion (Xmax) of the Apocalypse DB-5.5K 15" is 22.5 mm. This value indicates how far the diaphragm of the Subwoofer can move in one direction from its rest position without causing distortion. A larger Xmax value means that the Subwoofer can deliver deep bass with high pressure without compromising sound quality. The Xmax value is particularly important when the Subwoofer is operated at high volume, as it significantly contributes to the clarity and precision of bass reproduction.

How does the aluminum basket affect the performance of the Deaf Bonce Apocalypse DB-5.5K 15"?

The aluminum basket of the Apocalypse DB-5.5K 15" offers several advantages regarding the performance of the Subwoofer. Aluminum is a lightweight yet sturdy material that contributes to the overall rigidity of the construction. This reinforcement minimizes vibrations that occur during operation, leading to precise movement of the diaphragm. Additionally, aluminum promotes efficient heat dissipation, helping to avoid overheating and ensuring the reliability of the Subwoofer under high power demands. This results in cleaner bass reproduction, even at maximum volume.

What distinguishes the ferrite magnet of the Apocalypse DB-5.5K 15"?

The Apocalypse DB-5.5K 15" from Deaf Bonce uses a ferrite magnet known for its strength and durability. Ferrite magnets are ideal for Subwoofers as they provide a constant magnetic flux density necessary to drive the diaphragm evenly. They are efficient in converting electrical energy into mechanical energy, resulting in powerful and precise bass output. These specific characteristics make ferrite magnets particularly suitable for applications where reliability and continuous performance are important, as is the case with high-performance Subwoofers.
