SA18 v.2

Buy the Sundown Audio SA18 v.2 online at a great price and benefit from powerful highlights

The Sundown Audio SA18 v.2 delivers an impressive 1000 watts RMS of power at maximum power handling, combined with a premium motor design for reduced distortion. The 18-inch subwoofer features an aluminum Faraday ring that reduces induction distortion across its travel. Thanks to the robust 2.75-inch aluminum voice coil, which provides excellent heat dissipation, performance remains stable even under intensive use. The 19 mm linear excursion (Xmax) ensures deep, powerful bass, while the high-temperature copper voice coil withstands even the highest loads. With the Masori Lowest Price Guarantee, you can rest assured that you're always buying the SA18 v.2 at masori.de at the best price.

Xmax of 19 mm for impressive bass performance

The linear excursion (Xmax) of the Sundown Audio SA18 v.2 is 19 mm. This excursion, which maintains 70% of the BL force factor, ensures deep, distortion-free bass. In the car hi-fi world, an Xmax of 19 mm is above average and ensures the subwoofer remains clear and powerful even at higher volumes. A lower Xmax would limit the subwoofer's bass reproduction, while a higher value could allow for even more depth but also potentially expose it to mechanical problems.

Optimized RMS power of 1000 watts for powerful sounds

With a rated power of 1000 watts RMS, the Sundown Audio SA18 v.2 is optimally designed for loud and powerful bass reproduction. This high RMS power allows the subwoofer to operate safely and reliably even at high power levels. It is at the upper end of the range for car hi-fi subwoofers and ensures the delivery of even demanding audio signals without overloading or coil damage.

Selected D2 and D4 impedance for flexible installation

The Sundown Audio SA18 v.2 is available in D2 and D4 impedance versions. The dual 2-ohm (D2) and dual 4-ohm (D4) versions offer you flexible installation options to optimally match your amplifiers and achieve phenomenal bass. Selecting the wrong impedance can compromise the overall system's performance, as the amplifier-to-subwoofer ratio must be correctly balanced.

Subwoofer voice coil and cabinet construction sophisticated design

The 2.75-inch aluminum voice coil of the Sundown Audio SA18 v.2 boasts superior heat dissipation, allowing it to operate consistently even under high power demands. Aluminum, a high-quality conductor, prevents the subwoofer from overheating, even under demanding operating conditions. The choice of aluminum over other materials allows for higher continuous loads. With a sleek 18-inch design, the subwoofer fits seamlessly into a variety of vehicle speaker setups and excels both visually and acoustically.

Efficient induction prevention with aluminum Faraday ring

The Sundown Audio SA18 v.2 is equipped with an aluminum Faraday ring that minimizes magnetic induction distortion. The ring eliminates recurrent distortion in the center, resulting in a clear and powerful sound. Combined with the large magnetic gap height ratio, this design sets the subwoofer apart from many competitors and is a true highlight for sound enthusiasts who value precision.

Cabinet recommendations for perfect sound

The Sundown Audio SA18 v.2 achieves its full potential in a 127-liter bass reflex enclosure or a 99-liter sealed enclosure. These specific enclosure requirements ensure that the pressure and bass reflex are ideally matched, creating resonant sounds. A recommended 127-liter bass reflex enclosure optimizes bass reproduction, while the sealed enclosure ensures more precise sound quality. Miscalculating the volume could significantly compromise sound quality.

Thiele-Small parameters for acoustic fine-tuning

The T/S parameters make the difference: Vas of 114.234 liters at a D2 impedance and Vas of 106.964 liters at a D4 impedance provide insight into the effective operating volume. At the same time, the resonance frequency of 29.051 Hz (D2) and 31.868 Hz (D4) characterize the lowest frequency for the subwoofer's free vibration. Such precise parameters are essential for optimally matching the enclosure and listening environment, which further enhances the acoustic quality of the system.

Mechanical and electrical goods for a seamless balance

With Qms of 3.052 (D2) and 2.853 (D4) and Qes of 0.424 (D2) and 0.458 (D4), the Sundown Audio SA18 v.2 offers an excellent balance between mechanical and electrical losses. The Qts values ​​of 0.372 (D2) and 0.395 (D4) reflect the relative overall quality of the system, resulting in stable and powerful bass for a subwoofer of this class. Deviations from these values ​​may affect suitability for certain acoustic scenarios.

High force factor BL for precise control

A BL rating of 32.523 (D2) and 38.159 (D4) indicates the force factor of the Sundown Audio SA18 v.2. This ratio of magnetic force to voice coil movement demonstrates excellent control over the coil movement and ensures precise sound. A higher BL rating allows for greater pressure and more precise movement, but too high could result in compromised detail.

Integration of high-quality materials for best sound quality

The three-layer voice coil construction with high-temperature copper wire combines durability with high performance. Copper as a material ensures strong electrical conductivity, while the aluminum body structure provides rigidity. The design extends to the spring-loaded terminals to enhance sound fidelity and facilitates the subwoofer's full performance in daily use.
