Sundown Audio X-10 v3 D1 10 Dual 1-Ohm 2000W RMS Subwoofer

The Sundown Audio 10" 2000W RMS Subwoofer, known as the X-10 V.3 D1, boasts an impressive array of features and specifications that make it a standout in the low-frequency/small ported box subwoofer category. Designed to become the new standard in this price range, the X V.3 series is a different kind of woofer due to its incredibly linear suspension.

The subwoofer's key features include a Xmax of 30mm one-way by 70%, an RMS Power of 2000 watts, a vented magnetic gap, an optimized high-velocity pole vent, and an innovative high-velocity vented frame spacer ring. The 3-inch voice coil is made of black aluminum for superior heat dissipation, and the high-temperature round-wire CCAW voice coil is secured with high-temp black adhesive.

The 18-inch model of the X V.3 series features an optional tooled Sundown Frame that uses a 4-layer flat wire/all-aluminum coil, which is approximately 30% longer. The subwoofer also boasts a large aluminum faraday ring, spring-loaded terminals, and stitched-on double-XL tinsel leads to prevent fatigue and failure.

The Mega-Roll v.2 Surround Technology and the high-strength, custom-tooled, and patented cast aluminum frame contribute to the optimized coil ventilation system, which is a key feature of the X V.3 series.

In terms of specifications, the subwoofer has a DC resistance (Re) of 3.80 Ω, a resonance frequency (Fs) of 38.2 Hz, an equivalent volume (Vas) of 9.0 L, an electrical Q factor (Qes) of 0.53, a mechanical Q factor (Qms) of 4.93, a total Q factor (Qts) of 0.48, a voice coil inductance (Le) of 2.56 mH, a force factor (BL) of 24.8 NA, a moving mass (including air load, Mms) of 356.4 g, and a suspension compliance (Cms) of 0.05 mm/N. The sensitivity is rated at 81.6 dB 1w / 1m.

The recommended enclosure for this subwoofer is a ported box with a volume of 1.50 cu. ft. and a displacement of 0.21 cu. ft. The recommended tuning is 32 Hz, and the recommended port area is 24 sq. in.

The X V.3 series is designed to provide the lowest level of bass extension possible while maintaining low levels of distortion. Unlike traditional woofers, the X series frequency response does not change much over its full excursion range, resulting in a consistent and flat response at any volume level. This makes the X V.3 series a true low-distortion, high-excursion bass transducer that is unlikely to disappoint music enthusiasts.
