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.

PRECISION ENGINEERING
- With a BL product over 28 T·m and a linear, reinforced suspension system, the TCX-15 D1 maintains cone alignment and output at high levels of power and excursion. The 8-layer coil construction maximizes heat dissipation and current handling under extreme loads, while the carbon fiber cone delivers responsive, distortion-free performance.
- Ideal for both aggressive daily builds and professional demo applications, this D1 configuration gives you flexibility for low impedance amp wiring and full system optimization.
