Frequently Asked Questions about SW8-BMW


What power specifications does the SW8-BMW Subwoofer offer?

The Four Connect SW8-BMW Subwoofer has a power handling capacity of 100 Watts RMS and 180 Watts Max. With an impedance of 2 Ohms and a sensitivity of 88 dB, it delivers powerful bass reproduction. The 2″ copper voice coil allows for precise sound transmission, while the coated paper cone combined with the Nomex spider ensures stability and durability. Additionally, it uses a powerful neodymium magnet that optimizes the magnetic field. The technical parameters, such as Fs of 68.5 Hz and Qts of 0.97, are perfectly tuned to efficiently amplify low frequencies.

Which vehicles are compatible with the SW8-BMW Subwoofer?

The SW8-BMW Subwoofer from Four Connect is designed for numerous BMW models. These include the BMW 1 Series E81, E82, E87, E88, F20, F21, F40; 2 Series F22, F23, F44, F45, F46, F87; 3 Series E90, E91, E92, E93, F30, F31, F34, F80, G20, G21, G28, G80; 4 Series F32, F33, F36, F82, F83, G22, G23; 5 Series E60, E61, F07, F10, F11, G30, G31; 6 Series E63, E64, F06, F12, F13, G32; 7 Series E65, E66, F01, F02, G11, G12 as well as various X and MINI models like X1, X2, X3, X4, X5, X6 and R60, R61, F56, F55, F54, F57, F60. However, installation is specifically intended for models without Top HiFi systems.

Can the SW8-BMW Subwoofer be integrated into a Harman/Kardon type HiFi system?

The SW8-BMW Subwoofer is not suitable for BMW Top HiFi systems like Harman/Kardon or similar systems with codes S688A, S677A, and S752A. This is due to these systems' inability to handle a 2-Ohm load. However, it is compatible with HiFi packages S676A and S674A as well as with base packages without OEM amplifiers. The subwoofer particularly shines in vehicles without additional amplifiers, as these typically can efficiently drive low-impedance systems without overloading the amplifier.

How does the parameter Fs affect the sound of the SW8-BMW Subwoofer?

The parameter Fs, also known as resonance frequency, is 68.5 Hz for the SW8-BMW Subwoofer. This value indicates the frequency at which the subwoofer operates most efficiently and directly affects bass reproduction. A low Fs value suggests good bass capability, meaning that this subwoofer can deliver powerful and deep bass, especially in closed and compact enclosure applications. If you prefer music genres with intense bass, the Fs value ensures that the SW8-BMW optimally amplifies these frequencies.

What does the Qts of the SW8-BMW Subwoofer mean for its performance?

The Qts value of the SW8-BMW is 0.97 and describes the overall quality of the speaker in terms of its damping and resonance. Such a Qts level indicates a system that can be used in both closed and vented enclosures. For this subwoofer, the high Qts provides a wide range of bass that impresses in both closed enclosures and larger environments. Especially if you enjoy listening to loud music, the Qts value supports a balanced and powerful reproduction of low frequencies.

What role does the 2" copper voice coil play in the SW8-BMW Subwoofer?

The 2" copper voice coil of the SW8-BMW Subwoofer is crucial for the precise and effective conversion of electrical signals into mechanical movement. Copper is chosen as the material because it has excellent conductivity, minimizing energy consumption during signal transmission. This property optimizes fidelity, especially for low-frequency signals, and ensures consistent performance even under heavy load. With this technical design, the SW8-BMW provides clear and accurate bass reproduction at any volume.

What influence does the neodymium magnet have on the SW8-BMW Subwoofer?

The neodymium magnet of the SW8-BMW Subwoofer plays a central role in the efficiency and performance of the speaker. Neodymium is one of the strongest magnetic materials and allows for a more compact design of the speaker while increasing magnetic strength. This property improves the control of the speaker, which is particularly advantageous for the precise transmission of bass signals while maintaining low weight and space requirements. In practical installation situations, this means that the subwoofer can be mounted in tight spaces despite its robust performance.

How do Vas values affect the sound of the SW8-BMW Subwoofer?

With a Vas value of 17.3 liters, the SW8-BMW Subwoofer effectively describes the equivalent volume of air that is compressed at a certain frequency. The Vas value gives you an indication of how the speaker interacts with a cabinet. Higher Vas values suggest that the speaker performs better in larger enclosures, but can also produce solid bass in more compact installations. This balance between enclosure volume and sound depth ensures that you don't have to compromise on bass reproduction despite limited installation space.

What installation guidelines are there for the SW8-BMW Subwoofer?

The installation of the SW8-BMW Subwoofer from Four Connect is specifically designed for the spare part compartment under the front seats of BMW vehicles. It is important to ensure that the speaker is securely mounted to minimize unwanted vibrations and optimize sound quality. A secure fit not only ensures better sound performance but also reduces potential wear. Make sure that all electrical connections are properly and securely connected to ensure optimal use of the 2" copper voice coil and the neodymium magnet. Pay attention to the correct polarity to avoid phase shifts.

What are the advantages of the coated paper diaphragm of the SW8-BMW Subwoofer?

The coated paper diaphragm of the SW8-BMW Subwoofer offers an ideal mix of strength and lightness, supporting detailed and nuanced sound reproduction. Compared to other materials, paper balances robustness and flexibility, meaning that the subwoofer can reproduce complex bass lines with precision and without distortion. The special coating also makes the diaphragm more resistant to environmental influences, ensuring durability and stability. This property is particularly advantageous in BMW vehicles, where the subwoofer may be exposed to higher temperatures and humidity.
