Frequently Asked Questions about AS650

What cone material is used in the AS650 and why is it advantageous?

The AS650 uses synthetic metal as the cone material. This material is characterized by an excellent balance between strength and weight, contributing to improved sound behavior. Synthetic metal minimizes distortion and increases the precision of sound reproduction, especially in the mid frequencies. Additionally, it offers greater durability compared to conventional materials like paper or plastic. This material choice makes the AS650 ideal for HiFi solutions that require both a rich sound profile and longevity, especially in demanding applications such as mobile or stationary audio systems.

What impedance does the AS650 have and what impact does that have on audio playback?

The AS650 speaker has a DCR impedance of 4.0 Ω. A low impedance, like that of the AS650, means it requires less power from the Amplifier to achieve a certain volume level. This can lead to more efficient operation with less strain on the Amplifier. When pairing with Amplifiers, it is important that the Amplifier supports this impedance to ensure optimal sound quality. A four-ohm impedance is widely used in the automotive sector and offers a good compromise between sound quality and efficiency, especially when the speaker is used in vehicles with varying acoustic conditions.

What is the maximum power handling of the AS650 and what does that mean for its application?

The AS650 speaker has a maximum power handling of 40 W. This means that the speaker can be operated at maximum volume without distortion or damage, provided it is paired with an Amplifier that delivers this power. This design is particularly suitable for medium-sized automotive or home sound systems, where high volumes are not operated continuously. The relatively moderate power handling allows the speaker to be used in systems that do not have large power reserves without sacrificing sound quality.

What frequencies does the AS650 speaker cover and how does that affect sound quality?

The frequency range of the AS650 extends from 60 Hz to 6000 Hz. This range covers most essential frequencies important for clear and detailed music reproduction. Low frequencies starting from 60 Hz provide a solid bass presence, while mid frequencies up to 6000 Hz accurately reproduce the human voice. The comparatively limited upper frequency range suggests that this speaker is particularly suitable for applications where a strong and clear reproduction of musical mid-tones is required, making it ideal for speech and acoustic music genres.

How sensitive is the AS650 speaker and what does that mean for volume?

The AS650 has a sensitivity of 88 dB at 1 W/1 M. This sensitivity means that the speaker produces a volume of 88 decibels at a distance of one meter with one watt of input power. A higher sensitivity like that of the AS650 results in a higher volume at lower power input, which is particularly useful in energy-efficient applications. This can be crucial in vehicles to ensure high volume and a more intense sound experience without significant energy consumption from the amplifier.

Can the AS650 speaker be easily integrated into a car?

With a mounting depth of 64 mm and a cutout diameter of 143 mm, the AS650 is designed for easy integration into many common vehicle types. These dimensions fit standard mounts in many vehicle doors and are ideal for custom installations where space is a critical factor. However, compatibility with the specific vehicle model should always be checked for a perfect fit. Its compact design allows for seamless installation even in tight mounting openings without the need for major modifications to the vehicle trim.

What do the Thiele-Small parameters Qms, Qes, and Qts indicate about the AS650?

The Thiele-Small parameters provide information about the mechanical and electrical properties of the AS650 speaker. The Qms value of 3.08 describes the mechanical damping and indicates good control over the mechanical resonance point. The Qes value of 0.73 shows the electrical damping and is typical for speakers optimized for efficiency at low power consumption. The Qts value of 0.59 is a compromise value that expresses the overall quality and is ideal for applications where a balanced relationship between bass reproduction and efficiency is desired.

How heavy is the AS650 and what advantages does its weight bring?

The AS650 is remarkably light, weighing only 0.93 kg. This low weight significantly eases installation and means less strain on mounting surfaces, such as door panels in vehicles. A lighter construction can also contribute to improved sound characteristics, as it allows for more precise control of diaphragm movement. In mobile applications, a lower speaker weight reduces the overall consumption of the vehicle, which can lead to more efficient driving. At the same time, the material's inherent robustness ensures durability that conventional materials often do not provide.

How do I properly install the AS650 to achieve the best sound quality?

A correct installation of the AS650 is crucial for its acoustic potential. The installation location should be as stable as possible to minimize vibrations. Use the designated mounting screws to securely and flushly attach the speaker. Ensure that the frequency spectrum is optimally utilized by not blocking the speaker with obstacles that could affect the driver. The electrical connections should be clean and tight to avoid power losses. If possible, check the phase alignment of the speakers to minimize interference in the sound image, and use appropriate sealing elements if necessary to optimize the sound characteristics.

What is the frequency range of the AS650 ideal for?

The AS650 offers a frequency range of 60 Hz to 6000 Hz, ideal for applications where precise mid to high frequencies are required. This bandwidth is excellent for reproducing voices and instruments in the mid-frequency range. When used in home speaker systems or in vehicles, this speaker provides clear audio output, ensuring optimal presence in the midrange, especially for acoustic music or film playback. This speaker is ideal for users who prefer a natural sound without excessive use of equalizers or sound processors that artificially adjust the frequencies.
