Introducing the SUNDOWN AUDIO SD-4 SERIES 12" 600W DVC 4 OHM NEO CAR AUDIO SUBWOOFER NEO SD4. This premier sealed box subwoofer is the successor to the SD-3, offering exceptional depth and mechanical cushion.
The SD-4 series is designed to fit into applications with depth restrictions, making it the ideal choice for tight spaces. Unlike other woofers, the SD-4 does not require room for air venting behind the motor as it lacks a pole vent. This allows the motor to be flush against the back wall of the enclosure.
Featuring an all-new foam "W" shape surround, the SD-4 requires minimal space in front of the woofer gasket. This results in an effective total depth requirement that is around 2 inches less than most traditional woofers of equal depth. The SD-4 series also upgrades to NEO motors, reducing angled depth requirements substantially.
Not only does the SD-4 series offer a low mounting depth and small box requirements, it also delivers world-class sound quality. With its under-hung motor topology, the voice coil remains constant over the center portion of stroke, resulting in a flat BL curve. The newly tooled spider and "W" surround design work together to create a flat "center" compliance curve, making the SD-4 significantly more mechanically rugged than previous generations.
