The high-performance motor design of the SPK 12 is a key factor in its exceptional bass reproduction and efficiency. It allows for precise control of diaphragm movements, supported by the 3-layer high-temperature voice coil former. This construction results in increased thermal resilience and a reduction in mechanical losses. The dual damping system works hand in hand with the motor design to ensure clean, undistorted reproduction of low frequencies. This achieves an excellent balance between bass pressure and sound finesse, allowing the Subwoofer to sound great at both high and low volumes.

What does the Thiele-Small parameter mean for the SPK 12?

In Audiocontrol's SPK 12, the Thiele-Small parameters are of great importance to understand the acoustic behavior and performance of the Subwoofer. The mechanical Q factor (Qms) is 7.6824, the electrical Q factor (Qes) is 0.7362, and the total Q factor (Qts) is 0.6718. These values describe how the Subwoofer vibrates and where its strengths lie. The resonance frequency (Fs) is 37.3460 Hz, which provides insights into the tonal tuning. Its acoustic compliance volume (Vas) is calculated at 25.7006 L, ideal for tuned enclosures. These parameters are crucial for optimally integrating the Subwoofer into the audio environment.

What materials are used in the SPK 12 and why are they important?

The choice of materials in the Audiocontrol SPK 12 Subwoofer plays a significant role in sound performance and durability. The fiber matrix paper cone with mica coating minimizes distortion by optimizing stiffness and Damping. The 3-layer high-temperature voice coil former prevents overheating and enhances durability under high load. This combination of materials supports frequency-accurate reproduction, ensuring consistent, powerful bass notes. The removable Subwoofer Grille protects the diaphragm from external influences, thus maintaining performance over a long period. These robust materials are essential to ensure outstanding sound quality over time.

Are there any special installation instructions for the Audiocontrol SPK 12?

Yes, when installing the Audiocontrol SPK 12, there are some details to consider to ensure full sound quality. Due to the installation depth of 156 mm, it is important to create enough space in the enclosure or vehicle. The cutout diameter of 282 mm helps plan the precise integration. Using a suitable enclosure according to the recommended sizes is crucial to achieve efficient acoustic output. Additional mounting points should be used for secure installation, while the removable grille provides optimal protection for the Subwoofer diaphragm. This way, you ensure that no compromises are made regarding performance.
