Down4sound TCX 15-Inch Dual Voice Coil Subwoofer – 2700W RMS

Description

The DOWN4SOUND TCX 15” Subwoofer D1 is designed to take bass performance to the next level. Whether you’re pushing limits in the lanes or slamming the streets in a daily setup, this 2700W RMS sub is built to hit hard, stay cool, and deliver clean low-frequency output every time.

At the core of the TCX-15 is a 3-inch 8-layer flat aluminum voice coil, a carbon fiber cone, and a 5-stack Y35 ferrite motor. Together, this combination delivers extreme excursion, superior coil cooling, and high-pressure output — without compromise.
