SLD-10 von Sundown Audio Beschreibung

The Sundown Audio SLD series, which includes the SLD-10 10 inch shallow subwoofer, can be considered a "reboot" of the SD-2 line from 2011. The SD-2 was essentially a "shallow SA v1"—that is, it had the same cone, surround, and spider as the SA, but a shorter motor with a shorter coil. Starting with the 3rd generation (SD-3), the SD series took a different direction—more towards SQ and sealed enclosures (this also applies to the SD-4 series). Due to high demand, we launched the SLD series to bring back a highly abuse-tolerant "shallow" series that works well with open enclosures!

Similar to the current SD-4 series, we have used solid pole pieces, so the SLD can also be mounted directly on the rear enclosure wall to reduce the required net depth. Compared to the old SD-2, we have introduced numerous important upgrades: pole piece channels for reduced air noise and improved cooling, top plate "slots" for better cooling and less distortion, as well as a magnet ID shorting ring. Regarding long-term reliability, we have also screwed the tooth ring, assembled the motor with screws, screwed on the aluminum pole cap, and added "Mini-XL" lead wires to ensure flawless operation for many years.

Features

  • Xmax = 12 mm in one direction at 70% BL
  • Xmech is a hard limit of 25 mm in one direction (more than double Xmax is a very generous limit)

  • Ventilated, EMD-cut top plate design
  • Screwed motor construction for maximum durability and resistance to mechanical failures
  • ** This motor is screwed from the top, so the screws are not visible from the back as with some other models.
  • Magnet ID shorting ring

The resonance frequency (Fs) is 44.907 Hz for the SLD 10'' D2 model and 46.817 Hz for the D4 model. The electrical Q factor (Qes) is 0.452 for D2 and 0.547 for D4, while the mechanical Q factor (Qms) is 2.212 (D2) and 2.246 (D4). The total Q factor (Qts) is 0.376 for D2 and 0.440 for D4. Additionally, the compliance (Cms) is 85.883 uM/N for D2 and 70.979 uM/N for D4, and the moving mass (Mms) is 146.252 g for D2 and 162.818 g for D4.

Welche RMS-Leistung hat der Sundown Audio SLD-10 Subwoofer?

The Sundown Audio SLD-10 subwoofer has an RMS power of 600 watts. This performance is made possible by the use of a 2.5-inch black aluminum voice coil former, which ensures excellent heat dissipation. Additionally, it features high-temperature resistant voice coils made of 4-layer copper wire, designed for stable power delivery under demanding conditions. These features guarantee that the SLD-10 subwoofer delivers consistent and reliable performance over long periods, making it capable of meeting the high demands of music enthusiasts who desire powerful bass reproduction.

Wie lässt sich der Sundown Audio SLD-10 im Auto installieren?

The Sundown Audio SLD-10 can be easily installed in the car due to its flat design. It has a mounting depth of 12.4 cm and an outer diameter of 26.6 cm, making it flexible for various enclosure types. The cutout for installation should be 23.5 cm in diameter. The solid pole structure also allows for direct attachment to the enclosure wall to minimize space requirements. These construction features ensure that the subwoofer can be integrated into a wide range of installation environments without compromising sound quality.

Welche Gehäusearten sind für den Sundown Audio SLD-10 geeignet?

The Sundown Audio SLD-10 subwoofer is designed for use in various enclosure types to provide maximum flexibility. A sealed enclosure of about 14 liters is just as possible as a bass reflex enclosure with a volume of 28 liters. For the bass reflex enclosure, a recommended tuning of 35 Hz and a port area of 100 cm² are specified. These specifications ensure that the subwoofer is optimally utilized to produce precise and dynamic bass reproduction that excels both in the deep bass range and at high levels.

Welche besonderen Konstruktionsmerkmale weist der Sundown Audio SLD-10 auf?

The Sundown Audio SLD-10 is characterized by several innovative design features. Highlights include solid pole pieces with high-speed ventilation channels that improve cooling and reduce air noise. Additionally, the slots in the top plate contribute to less distortion and better cooling during operation. The bolted motor construction and screwed aluminum pole cap ensure the durability of the subwoofer. This design minimizes mechanical failures, allowing the SLD-10 to operate reliably even under adverse conditions. Especially if you enjoy listening to music at high volumes, you will benefit from these design upgrades.

Warum sind die Xmax und Xmech Werte des SLD-10 von Bedeutung?

The Xmax and Xmech values of the Sundown Audio SLD-10 are crucial for the performance of the subwoofer in operation. The Xmax value is 12 mm in one direction at 70% BL, which is important for full and distortion-free bass reproduction. Xmech represents a hard limit of 25 mm, more than double that of Xmax, allowing the subwoofer a generous tolerance under extreme loads. These values are indicators of how much the diaphragm can be moved from its rest position to achieve both high levels and not compromise structural integrity.

Welche Impedanz hat der Sundown Audio SLD-10?

The Sundown Audio SLD-10 subwoofer is offered in two impedance variants: as the SLD 10'' D2 with an impedance of 3.65 ohms and as the SLD 10'' D4 with 6.85 ohms. These variations allow the user to choose the subwoofer according to amplifier configuration and personal sound preferences. Impedance plays a crucial role in matching the subwoofer to the amplifier to ensure optimal power handling and sound quality. This allows for a perfect balance between power handling, heat generation, and efficiency for every application.

Welche Materialien werden für die Schwingspule des SLD-10 Subwoofers verwendet?

The voice coil of the Sundown Audio SLD-10 is made from high-quality material known for its thermal conductivity and mechanical load capacity. A 2.5-inch voice coil former made of black aluminum improves heat dissipation, while the 4-layer copper wire is manufactured for high temperature resistance. These materials ensure that the SLD-10 operates reliably even under high loads over an extended period. Additionally, the carefully selected materials reduce heat generation, which ensures efficient power transfer and flawless sound reproduction.

Inwiefern verbessert der Magnet ID Kurzschlussring die Leistung des SLD-10?

The magnet ID short-circuit ring in the Sundown Audio SLD-10 is a crucial component that enhances the performance and sound fidelity of the subwoofer. This short-circuit ring minimizes distortion due to inductive coupling and reduces thermal losses. This results in cleaner and more accurate bass reproduction. Furthermore, this ring optimizes the efficiency of the drive system by influencing the flow pattern in the magnetic circuit and protecting sensitive areas from overload. For the user, this means that the SLD-10 delivers consistent sound quality even at higher volumes and greater excursions.

Welche Vorteile bieten die Mini-XL Lamellenkabel des SLD-10?

The Mini-XL lamella cables of the Sundown Audio SLD-10 offer significant advantages in terms of load capacity and lifespan. These cables are sewn in and are designed to counteract fatigue and mechanical failure. Their robust construction ensures that the signal transfer between the individual components remains precise and reliable even under extreme conditions. Especially during intensive use or in sound systems that operate at high power for extended periods, the Mini-XL lamellas guarantee consistent performance without compromising sound quality. This not only improves the overall performance of the subwoofer but also helps to avoid costly repairs.
