Sundown Audio SA18 v.2

Buy the Sundown Audio SA18 v.2 online and benefit from powerful highlights

The Sundown Audio SA18 v.2 offers you an impressive 1000 watts of RMS power at maximum power handling and combines this with a first-class motor design for less distortion. The 18-inch subwoofer is equipped with an aluminum Faraday ring that reduces induced distortion across the excursion. Thanks to the robust 2.75-inch aluminum voice coil, which offers excellent heat dissipation, the performance remains stable, even during intensive use. The linear excursion (Xmax) of 19 mm ensures deep, powerful bass, while the high-temperature copper voice coil can withstand even the highest loads. With the Masori lowest price guarantee, you can be sure that you are always buying the SA18 v.2 at the best price on masori.de.

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 retains 70% of the BL force factor, ensures deep and distortion-free bass. In the Carhifi world, an Xmax of 19 mm is above average and ensures that the subwoofer remains clear and powerful even at higher volumes. A lower Xmax would limit the subwoofer 's bass response, while a higher value could allow even more depth, but also potential mechanical problems.

Optimized RMS power of 1000 watts for powerful sounds

With a rated output of 1000 watts RMS, the Sundown Audio SA18 v.2 is optimally designed for loud and powerful bass reproduction. This high RMS output enables the subwoofer to work safely and reliably even at high power levels. It is in the upper range for Carhifi subwoofers and offers delivery of even the most demanding audio signals without clipping or damage to the coil.

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 give you flexible installation options to match your amplifiers and achieve phenomenal bass. Selecting the wrong impedance can affect the performance of the overall system as the amplifier to subwoofer ratio must be correctly balanced.

Sophisticated subwoofer voice coil and enclosure design

The 2.75-inch aluminum voice coil of the Sundown Audio SA18 v.2 scores with outstanding heat dissipation, which means it works consistently even under high power loads. Aluminum, a high quality conductor, prevents the subwoofer from overheating even under more demanding operating conditions. The choice of aluminum over other materials allows for a higher continuous load. With an elegant 18-inch design, the subwoofer fits seamlessly into a variety of vehicle speaker setups and shines both visually and acoustically.

Efficient induction avoidance with aluminum Faraday ring

The Sundown Audio SA18 v.2 is equipped with an aluminum Faraday ring that minimizes magnetic induction distortion. Midrange recurring distortion is eliminated by the ring, resulting in a clear and powerful sound. In combination with the large magnetic gap height ratio, this design sets the subwoofer apart from many of its competitors and is a real highlight for sound lovers who value precision.

Enclosure recommendations for the perfect sound

The Sundown Audio SA18 v.2 unfolds its full potential in a bass reflex cabinet with a volume of 127 liters or a closed cabinet with a volume of 99 liters. These specific cabinet requirements guarantee that the pressure and bass reflex are ideally matched and create resonant sounds. A recommendation of 127 liters in the bass reflex cabinet optimizes the bass reproduction, while the closed cabinet ensures a more precise sound quality. A miscalculation of the volume could significantly impair the 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 D4 offer insights into the effective operating volume. At the same time, the resonance frequency of 29.051 Hz (D2) and 31.868 Hz (D4) characterizes the lowest frequency for the free vibration of the subwoofer. Such precise parameters are essential for optimally matching enclosures and listening environments, which further enhances the acoustic quality of the system.

Mechanical and electrical goods for a seamless balance

With a Qms of 3.052 (D2) and 2.853 (D4) and a 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 value of 0.372 (D2) and 0.395 (D4) shows the relative overall quality of the system, which means stable and powerful bass for a subwoofer of this class. Deviations from these values could affect the 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 power factor of the Sundown Audio SA18 v.2. This level of magnetic force to voice coil movement shows excellent control over the coil movement and ensures accurate sound. A higher BL rating allows for greater pressure and more accurate movement, but too high could lead to compromises in detail.

Integration of high-quality materials for the best sound quality

The three-layer structure of the voice coil with high-temperature copper wire combines durability with high performance. Copper as a material ensures strong electrical conductivity, while the aluminum-supporting body structure provides strength. Towards the spring-loaded terminals, the design improves fidelity and facilitates the full power delivery of the subwoofer in everyday use.
