    Frequently Asked Questions about PNW 57

    What advantages does the edge-reinforced steel frame of the Audiocontrol PNW 57 coaxial system offer?

    The edge-reinforced steel frame of the Audiocontrol PNW 57 coaxial system provides additional structural strength due to its robust construction. This feature is particularly important as it improves the stability of the system under various operating conditions and minimizes vibrations that could affect sound quality. The steel frame also contributes to the durability of the speaker, as it withstands mechanical stress. In combination with other materials, the steel frame ensures that the chassis optimally supports the precise movements of the cone, which is crucial for accurate sound reproduction. This way, the acoustic performance remains stable over long periods.

    How does the black anodized voice coil former affect the performance of the PNW 57?

    The black anodized voice coil former of the PNW 57 primarily ensures excellent heat dissipation, which is crucial for preventing thermal stress on the voice coil. The anodized coating also increases corrosion resistance, thereby improving the durability of the components. Effective heat dissipation is particularly important to avoid performance losses at high volumes, as overheating can lead to a deterioration of electrical properties. Thus, the voice coil former ensures consistently high acoustic reproduction quality, even when the speakers are operated at high levels for extended periods.

    What frequency ranges are covered by the PNW 57 and how is the crossover frequency of the system determined?

    The Audiocontrol PNW 57 covers a frequency range from 75 Hz to 20 kHz, allowing for a wide spectrum from deep bass to high tones. The crossover frequency set by the Crossover is at 5250 Hz. This XO frequency ensures that signals are efficiently divided between the midrange and tweeters, achieving harmonious sound reproduction. The filter type of the system is a Butterworth HP, known for providing a smooth frequency response with a slope of -6 dB per octave, resulting in minimal phase shifts in the crossover region.

    What are the dimensions of the Audiocontrol PNW 57 and what should be considered during installation in a car?

    The dimensions of the Audiocontrol PNW 57 are 140.6 x 221.9 mm in overall diameter, while the cutout diameter is 118 x 177 mm. The installation depth is 57 mm and the height is 5.6 mm, which can be suitable for many vehicle models. When installing in the car, it is especially important to measure the installation space in the door area accurately to ensure that there is enough room. Due to the motor diameter of 106 mm, it is also advisable to check the distance to other components to avoid any unwanted contact points.

    What is special about the linear double roll surround of the PNW 57?

    The linear double roll surround of the Audiocontrol PNW 57 is designed to precisely control the movement of the cone, which is crucial for distortion-free sound reproduction. This type of surround ensures that the cone moves without irregularities even at high volumes, significantly improving bass reproduction. The use of two roll surrounds provides better control of the diaphragm, which is particularly advantageous under high loads on the speaker. Additionally, the linear double roll surround helps maintain sound quality even after intense use, making the speaker overall more durable.

    How does the FEA-calculated motor contribute to the efficiency of the PNW 57?

    The FEA-calculated motor of the Audiocontrol PNW 57 has been optimized using Finite Element Analysis to ensure maximum efficiency in converting electrical to mechanical energy. This calculation ensures that the magnetic field is evenly distributed, increasing the speaker's drive power and improving efficiency. The efficient FEA motor plays a crucial role in achieving rich and accurate sound reproduction by precisely controlling the movements of the cone. This precision also leads to lower distortion and higher sound pressure, which is particularly beneficial if you enjoy listening to music at high volumes.

    What materials were used for the cone of the PNW 57 and why?

    For the cone of the Audiocontrol PNW 57, a stiff polyglimmer-coated material was chosen to achieve optimal sound reproduction. Polyglimmer increases the stiffness of the cone, helping to minimize vibrations and reduce resonances. These properties are essential to ensure precise and distortion-free audio reproduction. The coating also improves the durability of the material, allowing the speaker to remain faithful to its sound performance without interference over long periods. Thus, the choice of material significantly contributes to a clear and defined sound image, regardless of the volume.

    What functions does the rear-damped hybrid silk dome tweeter fulfill?

    The rear-damped hybrid silk dome tweeter of the Audiocontrol PNW 57 extends the system's frequency response and ensures detailed reproduction of high tones. The damping on the back minimizes unwanted resonances and distortions, resulting in a smooth and clear sound. This feature is particularly important for accurately reproducing highs without making the sound harsh. The tweeter harmonizes optimally with the midrange driver through the concentric point source design, which expands the soundstage. This creates a seamless transition between frequency ranges, providing an authentic listening experience.

    How does the concentric point source design improve the sound of the PNW 57?

    The concentric point source design of the Audiocontrol PNW 57 ensures seamless integration of the sound sources from the midrange and tweeter. This arrangement allows all frequencies to be emitted from a single point in space, making the sound image appear more natural and coherent. The even distribution of sound waves leads to improved directivity and a more consistent frequency response even outside the main axis of the speaker. This design choice helps minimize phase issues and optimizes the listening experience throughout the room. Especially if you value authentic reproduction, you will benefit from this thoughtful design approach.

    What is the technical significance of the XO frequency of 5250 Hz in the Audiocontrol PNW 57?

    The XO frequency of 5250 Hz in the Audiocontrol PNW 57 refers to the point at which the crossover separates the signal between the midrange and tweeter. A precisely defined frequency ensures seamless sound delivery between the drivers, minimizing distortions in the transition area. This tuning is crucial for sound harmony, as it allows the two sound sources to sound like a coherent unit. In developing the crossover, the Butterworth filter type was chosen, which provides a smooth filter characteristic with -6 dB per octave to make the sonic transitions as unobtrusive as possible.
