SA Classic 10"

Features and purchase incentives of the Sundown Audio SA Classic 10

The Sundown Audio SA Classic 10 subwoofer combines technical sophistication and performance—ideal for buy, buy online, or buy cheap at masori.de. With Masori's lowest price guarantee, you always secure the best price. This subwoofer offers a remarkable 750 watts RMS of power and is FEA-optimized. A vented magnet system ensures lower distortion. The 2.5 aluminum voice coil maximizes heat dissipation and withstands high temperatures—perfect for demanding applications in compact, sealed, or bandpass enclosures.

One-way excursion and maximum Xmax of the subwoofer

With a verified single-sided Xmax of 19 mm and an X-Mech of over 33 mm, the Sundown Audio subwoofer ensures excellent deep bass reproduction. This excursion means the subwoofer achieves exceptional depth and clarity without compromising sound precision. A larger Xmax would have allowed for even deeper bass reproduction, but could have increased the risk of distortion. This optimal combination makes the SA Classic 10 ideal for rhythmic and dynamic music styles.

Optimized motor and coil design with ventilation system

The FEA-optimized motor and coil design features a sophisticated ventilation concept that provides effective cooling for the voice coil. This minimizes temperature problems even under prolonged use, ensuring increased longevity. Without ventilation, the design would have been more likely to cause overheating, which could severely impact performance. The high-performance magnet ID shorting ring also contributes significantly to minimizing distortion.

SPL paper cone and foam surround of the SA Classic 10

The competition-grade SPL paper cone is robust and delivers a rich, unadulterated sound. Combined with the thick foam surround, the subwoofer not only offers durability but also efficiency in sound conversion. A weaker cone would reduce the subwoofer's power handling and impair the sound image. At the same time, the foam surround allows for flexible movement, which is essential for high-quality sound.

Nomex spider with XL strands for improved performance and reliability

The double-layer Nomex spider, comprising 84 XL strands, offers extreme robustness and reliability with maximum performance. This design minimizes the risk of failure due to strand breakage and contributes to the uniform vibration of the diaphragm. A simpler spider structure would increase the risk of mechanical wear. High-frequency processing ensures stable audio-electrical impedance.

Case recommendations for maximum audio performance

For optimal performance, we recommend a 14-liter sealed enclosure and a 28-liter bass-reflex enclosure tuned to 35 Hz. These specifications ensure that the subwoofer handles frequencies efficiently and makes the most of its environment. A smaller enclosure would not effectively reproduce the resonant frequencies, while an overly large enclosure could overly diffuse the bass. These recommendations are tailored for optimal sound reproduction.

Dimensions of the Sundown Audio subwoofer for flexible installation

With an outer diameter of 26.6 cm and a depth of 15.3 cm, the subwoofer can be flexibly integrated into the vehicle's surroundings. A 23.5 cm cutout allows for a precise fit. These compact dimensions are ideal for a variety of installation positions without requiring a lot of space. A larger model could pose installation challenges, while a smaller subwoofer would not do justice to the sound volume.

Thiele-Small parameters of the 10 D2 for detailed sound analysis

The RE of 4.29 ohms, Qts of 0.48, and sensitivity of 81 dB ensure high sonic transparency, while a BL of 20.40 NA ensures excellent electrical-to-mechanical power conversion. These parameters are essential for fine-tuning the system. A higher Qts value would indicate a less muffled sound, while a lower sensitivity would reduce the subwoofer's efficiency.

Spring-loaded terminals for secure connections

The spring-loaded terminals ensure a secure and stable connection, which is essential for uninterrupted audio flow. A poor connection would result in signal loss, which could directly impact sound quality. These high-quality terminals are specifically designed for high-performance applications to provide the user with absolute reliability.

Faraday ring to reduce electromechanical distortion

A large integrated aluminum Faraday ring actively controls inductance distortion, resulting in clearer sound reproduction. Without this ring, an undesirable change in the sound characteristics could occur, especially at high volumes. Such measures are essential to ensure consistent sound quality.
