Down4Sound TCX 10" 2700W RMS Subwoofer DVC

The DOWN4SOUND TCX 10” Subwoofer D2 delivers serious power in a compact package. Engineered for tight-space builds, daily drivers, or high-output demo setups, the TCX-10 features a 2700W RMS rating, oversized motor structure, and a 3-inch 8-layer flat aluminum voice coil for exceptional thermal handling.

A carbon fiber cone and stitched high-roll surround allow deep excursion without distortion, while the 5-stack Y35 motor and extensive venting ensure the sub stays cool under pressure. Designed for maximum performance in minimum space, the TCX-10 D2 is small, smart, and savage.
