Frequently Asked Questions about PNW 275


What are the performance specifications of the Audiocontrol PNW 275 midrange speaker?

The Audiocontrol PNW 275 midrange speaker offers an RMS power handling of 75 watts and a maximum power handling of 150 watts, making it ideal for a variety of applications where medium power is required. With an impedance of 3 ohms, it is compatible with most common amplifiers and audio systems. Its complex, FEA-optimized motor with high efficiency ensures that it makes optimal use of the available power and achieves outstanding sound reproduction. Especially if you enjoy listening to music at high volumes and desire clear playback even at loud levels, this midrange speaker is an excellent choice.

What is the frequency response of the Audiocontrol PNW 275 midrange speaker?

The frequency response of the Audiocontrol PNW 275 ranges from 100 Hz to 20 kHz. This provides an impressive bandwidth for reproducing midrange frequencies that are crucial for clear and detailed sound. The operating frequency range is from 200 Hz to 4 kHz, which means it is excellent for applications requiring precise reproduction of vocal-heavy material. The crossover frequency of 250 Hz and the slope of -6 dB per octave allow for sharp separation and clean overlaps with other speakers in a complete sound system.

What are the dimensions of the Audiocontrol PNW 275 midrange speaker?

The overall dimensions of the Audiocontrol PNW 275 are 95 mm, with the overall diameter (without grille) measuring 72 mm. The cutout diameter is 67 mm, which is important when planning the installation. The mounting depth of 35 mm should be noted to ensure compatibility with the installation location. A mounting height of 1.5 mm (without grille) allows for a fairly flat installation. When the grille is used, the installation height increases to 12.4 mm. These are important sizes for installation in various speaker systems or vehicles.

How does the Audiocontrol PNW 275 ensure efficient heat dissipation?

The Audiocontrol PNW 275 midrange driver is equipped with a black anodized voice coil former that allows for excellent heat dissipation. This feature is crucial for operation at high volumes or during prolonged use, as it minimizes the risk of overheating the components. The voice coil former not only significantly contributes to the longevity of the speaker but also helps maintain audio quality consistently at a high level by efficiently dissipating heat from the voice coil.

What materials are used in the Audiocontrol PNW 275 midrange driver for sound quality?

The PNW 275 midrange driver uses a paper fiber matrix with a mica coating for the cone, resulting in optimized sound reproduction. The mica coating improves internal damping and resonance, allowing for detailed and vibrant midrange reproduction. Additionally, the transparent dust cap made of thermopolymer provides the highest sound fidelity by protecting the cone from dust while keeping the sound radiation uncolored. This combination of materials is crucial for the speaker's ability to reproduce sounds with high quality and precision.

What role does the FEA-calculated motor play in the PNW 275 midrange driver?

The PNW 275 from Audiocontrol is equipped with a complex, FEA-calculated motor that enables high efficiency. FEA stands for Finite Element Analysis, an advanced method for modeling and optimizing electric motors and structural components. This calculation ensures that the motor operates not only powerfully but also efficiently, leading to improved performance and sound reproduction. This is particularly important for detail fidelity when reproducing complex audio tracks and ensures an optimized listening experience.

What does the impedance of 3 ohms mean for the Audiocontrol PNW 275?

The impedance of 3 ohms in the Audiocontrol PNW 275 midrange driver offers a low electrical load, which in practice means it can efficiently draw more power from an amplifier. This allows for louder playback performance with less energy loss compared to speakers with higher impedance. Choosing an amplifier that can operate stably at 3 ohms is crucial to maximizing sound quality while protecting the amplifier from overload. A 3-ohm speaker realizes its full potential in compatible audio systems.

What measures guarantee the structural strength of the Audiocontrol PNW 275?

The PNW 275 from Audiocontrol offers additional structural strength through its edge-reinforced steel frame. This construction not only secures the stability of the midrange driver but also eliminates unwanted vibrations that could affect sound quality. Especially in mobile applications, such as in vehicles, a robust design is crucial to withstand mechanical stresses. This construction ensures reliability and sound fidelity, even under demanding conditions, such as heavy bass or on unpaved roads.

How easy is the installation of the Audiocontrol PNW 275 in the vehicle?

Thanks to the compact overall dimensions of 95 mm and a cutout diameter of 67 mm, the Audiocontrol PNW 275 can be easily installed in most vehicles. The installation depth of 35 mm ensures that it can be installed with minimal modifications in standard speaker cutouts. Supplied high-quality mounting materials simplify the installation. When planning, it is essential to consider the specific dimensions to ensure that the midrange driver fits into the intended enclosure, with the maximum mounting height (without grille) being 1.5 mm.

Why is the linear surround important for the PNW 275 midrange driver?

The linear surround of the PNW 275 midrange driver plays a crucial role in precise cone movement. This feature ensures that the cone vibrates evenly, reducing distortion in sound reproduction. Especially when reproducing complex musical passages, this precision is essential to maintain the details in the audio material. The linear surround also contributes to the longevity of the speaker by absorbing mechanical stress more effectively, ensuring consistent performance over a longer period.
