Sundown U18 18 inch D4 ohm subwoofer 1500 watts rms Car Audio

This sub was installed for one day and was just too loud for my small car. The only visible wear is at the mounting holes. It is otherwise in like new condition The voice coils are dual 4 ohm. Jacob Fuller and the team spent over a year to design, engineer, and tool proprietary elements to ensure the U-Series stands up to the incredibly high expectations set by Sundown and their lineup. The U Series utilizes the same 1500 watt RMS Voice Coil as the entire X-V2 (10-18) series with a similar rear-vented motor design. The U Series is the most direct replacement in the Sundown line for the world famous Z-v. 3 series that was available from 2011 through 2016. The U varies from its similarly power-rated sibling, the X series, in that it does not use the Sundown new platform frame, spider, and surround technology. The U series is equipped with an extremely capable traditional suspension design which results in a punchier sound when compared to the new platform woofers. It also lends itself better to high-frequency SPL competition classes for the same reason. The list of "custom tooled" parts designed specifically for this sub is seemingly never-ending; including custom cone body, custom surround larger and thicker than the Z-v.

3 series, custom cast aluminum vent spacers, and a completely new cast aluminum surround bolt-on ring. Black Aluminum 3 voice coil former for superior heat dissipation. High Temperature Round-Wire CCAW voice coil with high-temp black adhesive. Spring loaded terminals accept up to 8 gauge.

Innovative high-velocity cast aluminum vented frame spacer ring. Cast Aluminum surround bolt-on rings. Optimized for small ported or bandpass enclosures. Linear X-Max by 70% BL : 30 mm one-way. Recommended Port Area: 64 in^2.
