Frequently Asked Questions about ATC100S


How does the NBR nitrile rubber surround affect the sound quality of the Axton ATC100S?

The linear NBR nitrile rubber surround of the Axton ATC100S ensures excellent sound quality through precision and durability. The woofer/midrange speaker benefits from the resonance-free polypropylene diaphragm, which is stabilized by the NBR surround. This combination reduces unwanted vibrations and provides a clear sound. The choice of material for the surround also enhances dynamics and allows for more precise bass reproduction.

What advantages does the strontium ferrite magnet in the Axton ATC100S offer?

The strontium ferrite magnet in the Axton ATC100S provides effective power transfer and ensures high efficiency of the speaker system. In conjunction with the resonance-free diaphragm of the woofer/midrange speaker, improved clarity is achieved across the entire frequency range. The strong magnetic force enables both precise and dynamic music reproduction, especially in the bass frequencies, without compromising the sensitivity of 86 dB.

How does the neodymium magnet with ferrofluid cooling affect the performance of the tweeter in the Axton ATC100S?

The neodymium magnet with ferrofluid cooling enhances the performance of the 25 mm tweeter through optimized heat dissipation and increased driving force. This design reduces distortion and maintains high sound purity even at higher volume levels. At the same time, the mounted diffuser ensures precise spatial imaging and contributes to excellent sound quality. The cooling provided by ferrofluid supports the stability and longevity of the tweeter under continuous load.

What advantages does the polyimide carrier voice coil of the ATC100S offer?

The voice coil located on a polyimide carrier of the ATC100S provides high thermal stability and long-term durability. This material offers both mechanical strength and high resistance to temperature increases during intense use. As a result, sound precision is maintained even at a continuous high power input of 60 Wrms. The polyimide carrier structure minimizes distortion and supports clear and clean audio reproduction.

What installation requirements exist for installing the ATC100S speaker set?

The Axton ATC100S requires a mounting diameter of 93 mm and a mounting depth of 39 mm to ensure optimal fit. The robust construction and gold-plated connectors facilitate installation. Additionally, a mounting adapter for the tweeters is included, allowing for both surface and recessed installation. These flexible installation options ensure that the speaker set can be easily integrated into compact installation spaces.

How does the Crossover in the ATC100S support sound reproduction?

The space-saving 6 dB/octave in-line Crossover of the ATC100S supports sound reproduction through precise frequency separation and ensuring an optimal signal path to both the Midrange speakers and the Tweeter. This results in a balanced sound image. The level reduction allows for adjusting the Tweeter by -3 dB, thus tailoring the sound performance to individual needs or room acoustics without distorting the natural timbre.

What influence does the nominal impedance of the ATC100S have on speaker performance?

The nominal impedance of 4 Ohm of the Axton ATC100S positively influences speaker performance by supporting the current flow from the Amplifier. A lower resistance value allows for more efficient use of the supplied power, which directly translates into higher sound pressure and thus volume. This impedance is optimally designed for conventional amplifier systems, enabling harmonious collaboration between components without loss of power or overloading.

What role do the gold-plated connectors play in the Axton ATC100S Speaker Set?

The hard gold-plated, corrosion-resistant connectors of the Axton ATC100S ensure a stable and durable electrical connection. These connectors minimize resistance and prevent signal loss and interference by ensuring reliable signal transmission. Especially in more humid environments or with larger frequency fluctuations, these special connectors provide added value by significantly reducing the risk of contact corrosion.

How does the Axton ATC100S Speaker Set perform in the frequency spectrum?

The Axton ATC100S Speaker Set covers a frequency range from 90 Hz to 25 kHz, allowing for detailed reproduction of both low and high tones. This bandwidth ensures a comprehensive listening experience by reproducing all acoustic details. The precision in the low frequencies is complemented by the resonance-free polypropylene membrane, while the Tweeter, supported by the diffuser and neodymium magnet, reproduces the highest frequencies with clear brilliance.

What influence does the diffuser have on the Tweeter in the Axton ATC100S?

The diffuser in the 25 mm Tweeter of the Axton ATC100S plays a crucial role in enhancing spatial sound reproduction. Through its design, it directs the high frequencies to achieve an even sound distribution in the room. This leads to an optimal stereo stage and ensures that the listener enjoys a realistic and immersive sound experience, regardless of their position in the room. The integration of the diffuser thus elevates the sound quality of the entire set to a higher level.
