Frequently Asked Questions about SN 12

What are the Thiele-Small parameters of the SN 12 from SUB19?

The Thiele-Small parameters of the SN 12 are crucial for its performance. The DC resistance Re is 4.17 Ohms, while the impedance at the self-resonance frequency Fs is 54.61 Ohms. The self-resonance frequency itself is 29.0 s^-1, an indicator of the fundamental frequency of the Subwoofer. The mechanical quality factor Qms is relatively high at 4.266, while the electrical quality factor Qes is 0.353. The total quality factor Qts is 0.326, which means that the SN 12 is optimized for its efficiency in bass reflex enclosures. These parameters help define the characteristic sound signature of the SN 12.

How does the SN 12 from SUB19 perform in different enclosures?

The SN 12 Subwoofer is ideal for various enclosure types due to its flexible mechanical properties, such as the large maximum displacement. In bass reflex enclosures, it demonstrates its high efficiency by optimally converting sound pressure. If you want to use enclosures of different sizes or shapes, you should consider the Thiele-Small parameters to achieve the best performance. The effective diaphragm area of 460.0 cm² supports greater air displacement, which is essential for maximizing performance from any enclosure design. Even in sealed enclosures, its displacement capability remains unaffected, highlighting its versatile applicability.

What distinguishes the TI-Frame of the SN 12 Subwoofer?

The TI-Frame of the SN 12 from SUB19 is a critical feature that provides the Subwoofer with its structural integrity. This frame is known for its stability and durability, which is particularly advantageous at high sound levels. Since the Subwoofer maintains its shape even under heavier loads, you can achieve high power levels without distortion. The construction of the TI-Frame also allows for precise movement of the diaphragm, significantly improving sound quality. If you have an audio setup that demands high durability, the TI-Frame is an indispensable element.

Where does the SN 12 Subwoofer from SUB19 show its impressive displacement?

The impressive maximum excursion of the SN 12 Subwoofer is one of its outstanding features. This capability minimizes the risk of the voice coil or spider hitting, which often happens at high volumes. Especially if you enjoy listening to music loudly, the excursion allows for deep and clear bass reproduction without distortion. This specification is particularly important for the longevity of the Subwoofer and ensures that no mechanical damage occurs even with intense use. The large excursion capability is thus a significant advantage for discerning audiophiles.

What role do the Thiele-Small parameters play in the bass reflex application of the SN 12?

In bass reflex applications, the Thiele-Small parameters of the SN 12 are particularly crucial. The electrical quality factor Qes of 0.353 and the total quality factor Qts of 0.326 are ideal for this application, as they promote efficient air movement through the port. The resonant frequency Fs of 29.0 s^-1 complements this by enabling deep, clean bass reproduction. Additionally, the high mechanical quality factor Qms of 4.266 ensures excellent mechanical control. All these factors contribute to the excellence that the SN 12 can demonstrate in various bass reflex designs.

What is special about the effective diaphragm area of the SN 12?

The effective diaphragm area of the SN 12 is 460.0 cm² and is an essential component of its performance. A larger diaphragm area means that more air can be moved, which provides powerful and deep bass. This specification is particularly important when you need high bass impact while maintaining clear sound reproduction. The area also contributes to the robustness of the system and helps maximize the load capacity in demanding listening situations. This keeps the Subwoofer stable even at high volumes, ensuring more consistent sound experiences.

How does the force factor Bl affect the performance of the SN 12 from SUB19?

The force factor Bl of the SN 12 is 29.70 Tm and plays a central role in the performance of the Subwoofer. It describes the strength of the magnetic field and the length of the wire in the magnetic field. A high Bl value like this allows the Subwoofer to operate more efficiently and precisely. This means the SN 12 can convert more power into sound pressure while providing controlled bass reproduction. With the high Bl value, the Subwoofer is particularly well-equipped to reproduce dynamic audio signals accurately and powerfully, which is advantageous for complex musical pieces.

How does the inductance of the coil Le affect the sound of the SN 12?

The inductance of the coil Le of the SN 12 is 7.161 mH and is crucial for the sound quality, especially in the high-frequency range. A higher inductance usually means that the Subwoofer can operate at lower frequencies, but it can also lead to some damping in the high frequencies. With the SN 12, the balanced inductance ensures that both low and mid tones can be reproduced clearly and in detail. This feature allows the SN 12 to work effectively in complex audio environments, and it is ideal when you are looking for the most complete sound fidelity in playback.

What are the dimensions of the SN 12 and how does this facilitate installation?

The SN 12 has a diaphragm area of 460.0 cm², making it compact enough for easy installation despite its power. Depending on the vehicle and enclosure type, it is important to measure the available space to optimally integrate the Subwoofer. Thanks to its dimensions and carefully selected components, the SN 12 can be flexibly used in various speaker concepts, whether in bass reflex or sealed enclosures. With a suitable installation location, the acoustic performance can be maximized, while the flexibility of the SN 12 offers many customization options for the ideal sound.

What is the efficiency of the SN 12 Subwoofer at 1 watt of power?

The efficiency of the SN 12 from SUB19 is 83.68 dB SPL at 1 W at a distance of 1 m. This value is an indicator of how efficiently the Subwoofer converts sound into sound pressure. A high efficiency like this is important because it means that the Subwoofer can produce loud and clear tones even at lower power levels. This is ideal for applications where amplifier potential is limited but strong bass reproduction is still needed. The efficiency helps ensure that the SN 12 performs excellently in any environment, from home theater to vehicle installation.
