    Frequently Asked Questions about Access 100AC

    What power does the Focal Access 100AC speaker provide?

    The Focal Access 100AC is a coaxial speaker with a nominal power of 40 Watts RMS and a maximum power of 80 Watts. These power specifications indicate that the speaker is ideally suited for moderate volume levels while maintaining its sound quality. With a sensitivity of 87.2 dB (2.83 V/1 m), you can ensure that the speaker operates efficiently and produces sufficient volume with low distortion. The nominal impedance of 4 Ohm means that the speaker works well in most car audio systems. Especially if you enjoy listening to music at high volumes, the Access 100AC offers an excellent sound balance.

    What technical specifications does the Focal Access 100AC have?

    The Access 100AC coaxial speaker features a range of specified technical parameters. For example, the voice coil diameter measures 25 mm and the height is 10 mm, ensuring stable and dynamic sound reproduction. The fiberglass diaphragm combined with a butyl suspension provides excellent sound characteristics and durability. The DC resistance (Re) is specified at 3.4 Ohm, while the flux density is at 0.9 T, contributing to high efficiency. The magnet measures 72 x 15 mm and weighs 160 g, supporting a total net weight of 0.6 kg. Crucial for bass reproduction is the linear excursion of ±2.5 mm.

    What Thiele/Small parameters does the Focal Access 100AC have?

    The Thiele/Small parameters of the Focal Access 100AC are crucial for characterizing its acoustic properties. The resonance frequency (Fs) is 110.12 Hz, which is relevant for the upper cutoff frequency of bass reproduction. Vas, which corresponds to the equivalent volume, measures 1.07 liters, while Qts, a measure of the coupling efficiency, is at 0.824. Qes and Qms, other parameter sets, are 0.96 and 5.82, representing electrical and mechanical losses, respectively. Additionally, Sd at 52.81 cm² and the mechanical resistance Rms at 0.912 kg/s are other important parameters that support overall performance. Les measures 5.13 mH and Res 20.67 Ohm, while Cms is 272 µm/N.

    How compatible is the Focal Access 100AC with vehicles?

    The Access 100AC coaxial speaker is built with an outer diameter of 4 inches (10 cm), allowing it to fit in many vehicles that have OEM mounting positions for speakers of this size. The installation should be checked to ensure there is enough space for the speaker with the height of the voice coil at 10 mm and the magnet measuring 72 x 15 mm. If you have a vehicle interior that is tight on space, it is advisable to check the exact dimensions. Make sure that the installation depth is compatible with the structural elements of your car and provides enough room to prevent distortion in sound reproduction.

    What materials are used in the Focal Access 100AC?

    The Focal Access 100AC uses high-quality materials that contribute to improved sound reproduction. The diaphragm is made of fiberglass, which provides considerable stiffness and low weight, thus reducing distortion. Additionally, a butyl surround encircles the diaphragm, ensuring both flexibility and durability for long-lasting performance. The magnet is sized at 72 x 15 mm and ensures an adequate flux density of 0.9 T, which provides consistent performance. Furthermore, the voice coil is designed with a diameter of 25 mm and a height of five millimeters to achieve a faster response to signals.

    How does the Focal Access 100AC perform in different acoustic environments?

    The performance of the Focal Access 100AC in various acoustic environments can be assessed based on its sensitivity, impedance, and Thiele/Small parameters. With a sensitivity of 87.2 dB (2.83 V/1 m), the speaker produces sufficient volume at low amplifier power. Thanks to the nominal impedance of 4 Ohm, it can be integrated flexibly into audio systems, ensuring a consistent sound without significant electrical strain. Fs and Vas are essential indicators for assessing low-frequency reproduction in acoustically sealed or reflective environments. The Qts of 0.824 and Sd of 52.81 cm² ensure a balance between ultra-bass resonance and mid to high acoustic levels.

    What sound characteristics does the Focal Access 100AC offer?

    With the Access 100AC, sound reproduction is outstanding in both presence and transparency. The fiberglass diaphragm allows for clear and precise identification of mids and highs, while the butyl surround adds more volume to the lows. The linear excursion of ±2.5 mm minimizes distortion and enables even the quietest sound passages to be reproduced with exact detail fidelity. The frequency response is influenced by the resonance frequency (Fs) at 110.12 Hz and the Thiele/Small parameters, particularly the Qts of 0.824. Thus, the speaker offers consistent sound quality across a wide spectrum without overemphasis, providing music lovers with a homogeneous and pleasant listening experience.

    How easy is the installation of the Focal Access 100AC in a car?

    The installation of the Focal Access 100AC is extremely straightforward due to its compactness and specific dimensions. With a diameter of 4 inches (10 cm), this speaker is ideal for standardized installation spaces in vehicles. It is important to check the space for the magnet, which measures 72 x 15 mm, and the voice coil with a diameter of 25 mm during installation. Ensure a stable mounting to minimize vibrations and unwanted frequencies. The drill holes must be selected to match the Speaker Set to ensure a secure installation. When properly installed, the Access 100AC provides a clean and powerful listening experience without complicated adjustments.

    What acoustic performance does the Focal Access 100AC show in the bass range?

    The bass range of the Focal Access 100AC benefits from its sophisticated technical specifications. The resonance frequency of 110.12 Hz, combined with the fiberglass-reinforced diaphragm and butyl suspension, allows for clear and powerful reproduction of low-frequency ranges. The Thiele/Small parameters, such as a Vas of 1.07 liters and a Qts of 0.824, contribute to optimized bass reproduction by integrating the physical conditions of the vehicle environment. On one hand, the linear excursion of ±2.5 mm ensures that the movement range for bass is ideally utilized, while on the other hand, the flux density of 0.9 T supports a uniform application of magnetic force. These specifications result in a nuanced, deep bass sound.

    How does the choice of diaphragm material affect the performance of the Focal Access 100AC?

    The choice of fiberglass diaphragm in the Focal Access 100AC influences the sound through more efficient vibration behavior and improved stability. Fiberglass offers the advantage of stiffness without additional weight compared to more traditional, heavier materials, which plays a central role in sound output without distortion. The elasticity of the butyl suspension contributes to damping unwanted vibrations and long-term stability. The voice coil with a diameter of 25 mm also contributes to fast impulse responses. This combination ensures precise and balanced sound reproduction across all frequency ranges, especially in the mid to high tones, without compromising performance.
