SA Classic 10 inch by Sundown Audio Description

During the development of the SA Series, which includes the Sundown Audio SA Classic 10 Inch Subwoofer, Sundown Audio started with an FEA-optimized motor and coil design that allows for a 19 mm verified one-way Klippel excursion and just over 33 mm x-mech. This motor and coil construction was then combined with an extremely robust dual-layer Nomex spider with fully bonded "XL" leads (84 strands), a competition-grade SPL paper cone, and a strong foam surround. The motor also features a large magnet ID shorting ring (Faraday ring) to reduce distortion from inductance and inductance variation over the stroke.

Features

  • Xmax = 19mm one-way at 70% BL
  • RMS Power = 750-Watt
  • Vented magnet gap
  • Optimized high-speed pole venting
  • Innovative vented high-speed frame spacer ring
  • 2.5 inch black aluminum voice coil former for excellent heat dissipation
  • High-temperature copper voice coil wire
  • Large aluminum Faraday ring (Magnet ID)
  • Spring-loaded terminal posts
  • Sewn "XL" tinsel leads to prevent fatigue and failure
  • High-strength cast aluminum frame
  • Optimized for small sealed and bandpass enclosures
  • These features together create the optimized coil ventilation system.

Frequently Asked Questions about SA Classic 10 inch

Was zeichnet den Sundown Audio SA Classic 10 Subwoofer besonders aus?

The Sundown Audio SA Classic 10" subwoofer stands out with its FEA-optimized motor and coil design, allowing for a one-way Klippel excursion of 19 mm and an X-Mech of over 33 mm. The subwoofer combines an extremely robust double-layer Nomex spider, equipped with fully bonded XL wires (84 wires) and a competition-grade SPL paper cone. The strong motor with a large magnet ID short-circuit ring (Faraday ring) minimizes distortion due to inductance and fluctuations in travel. Additionally, the high-speed frame spacer provides excellent ventilation for the magnetic gap.

Welche RMS-Leistung bietet der SA Classic 10 Subwoofer?

The Sundown Audio SA Classic 10" subwoofer has an impressive RMS power of 750 watts. This performance is ensured by a combination of a ventilated magnetic gap and an optimized high-speed pole ventilation system. The 2.5" voice coil former made of black aluminum additionally contributes to excellent heat dissipation and ensures reliable performance even in intense applications. These design features combined lead to consistent power delivery and optimized coil ventilation, making the subwoofer ideal for demanding applications.

Wie groß sollte das Gehäuse für den Sundown SA Classic 10 sein?

For the Sundown Audio SA Classic 10" subwoofer, a sealed enclosure volume of 14 liters is recommended, while a bass reflex enclosure volume of 28 liters is ideal. The subwoofer is also designed for a recommended tuning of 35Hz. These enclosure volumes ensure optimal sound reproduction and bass performance. When installing, it is also important to consider the recommended connection areas in the enclosure, which are at 100cm². This information helps to minimize vibrations and unwanted resonances, leading to clearer and more precise bass reproduction.

Welche technischen Daten hat der SA Classic 10 Subwoofer?

The Sundown Audio SA Classic 10" has various technical specifications: The D2 version has a Re (Ohm) of 4.29, an Fs (Hz) of 35.4, and a VAS (L) of 10.13. The Qes is also at 0.52, Qms at 5.41, and Qts at 0.48. The sensitivity measures 81.0 dB @ 1w/1m. In the D4 model, some values change slightly: Re (Ohm) is 7.08, Fs (Hz) is 36.6, and VAS (L) is 10.66, Qes 0.54, Qms 5.30, Qts 0.49, and the sensitivity is 81.6 dB. These parameters directly influence the sound characteristics and performance of the subwoofer.

Welche besonderen Materialien werden beim Sundown Audio SA Classic 10 verwendet?

The Sundown Audio SA Classic 10" relies on special materials for maximum performance. This includes a double-layer Nomex spider with 84 fully bonded XL wires, which ensures high flexibility and durability. The voice coil is made of high-temperature copper wire and is wound around a 2.5" voice coil former made of black aluminum, known for its excellent heat dissipation. Furthermore, the subwoofer features a competition-grade SPL paper cone and a durable foam surround, which together ensure a robust and high-quality construction, equipping the subwoofer for extreme SPL use.

Warum ist die Belüftung beim SA Classic 10 entscheidend?

The ventilation in the Sundown Audio SA Classic 10" is crucial for ensuring consistent performance and longevity. This includes the ventilated magnet gap as well as the optimized high-speed pole ventilation system, which reduces the temperature of the voice coils. The ventilated high-speed frame spacer also contributes to efficient cooling, thus preventing thermal overload even at high volumes. These advanced cooling features are particularly beneficial for minimizing distortion across the stroke and maintaining consistent acoustic performance.

Ist der SA Classic 10 kompatibel mit gängigen Automarken?

Wie tragen die Thiele-Small-Parameter zur Leistung des SA Classic 10 bei?

The Thiele-Small parameters of the Sundown Audio SA Classic 10" provide essential information about the behavior of the subwoofer under various conditions. Values such as Qts of 0.48 and 0.49 for the D2 and D4 models respectively are indicators of efficiency and suitability for enclosures. Re (Ohm), Bl (NA) of 20.40 and 24.82, as well as other parameters, determine how well the subwoofer converts electrical power into acoustic energy. These parameters assist in the proper selection of enclosures and tuning of the subwoofer for optimally adjusted bass response behavior.

Wie sollte der Sundown Audio SA Classic 10 montiert werden?

The installation of the Sundown Audio SA Classic 10" requires careful planning regarding placement and enclosure selection. With a recommended bass reflex enclosure volume of 28 liters and a tuning of 35Hz, it is important to design or select the enclosure to meet these parameters. The depth of the subwoofer is 15.3cm, the outer diameter is 26.6cm, and the cutout is 23.5cm, allowing for adaptation to most standard enclosures.
