Down4Sound TCX 15” Subwoofer – Dual 1Ω (2700W RMS)
The Down4Sound TCX 15” D1 is built to crush — tuned for deep, controlled bass and engineered to handle brutal power daily. It features a 3-inch 8-layer flat aluminum voice coil, carbon fiber cone, and stitched surround supported by a triple-spider suspension for maximum stability under pressure.
Powered by a 5-stack Y35 ferrite motor and full venting throughout the motor and backplate, this sub stays cool and consistent no matter how hard you push it. Designed for both demo beasts and clean daily setups, the TCX 15” is a powerhouse you can trust.
Key Features:
-
Massive 5-stack Y35 ferrite motor for unmatched magnetic force
-
3" 8-layer flat aluminum voice coil for superior power handling
-
Carbon fiber cone and stitched surround for clean, tight bass
-
Triple-spider suspension system for precise cone alignment
-
Fully vented motor and backplate for thermal stability
-
Extended pole piece for deep, controlled excursion
Specifications:
-

-
Sensitivity: 84.9 dB
-

Precision Engineering:
With a BL rating of 20.164 T·m and Fs of 28.94 Hz, the TCX 15” D1 is designed to hit hard while staying musical and controlled. The 8-layer coil maximizes heat dissipation and power efficiency, while the triple-spider design keeps cone movement perfectly linear.
Summary:
The TCX 15” D1 delivers the deep, violent lows every basshead craves — without sacrificing control or reliability. Built for daily abuse and demo-level output, it’s the sub that keeps pounding when others tap out.
