Product details
D-Series 12-inch DVC output
TS-D12D4 scales the D-Series formula to 12 inches with 600 W RMS / 2,000 W peak. Dual 4-ohm coils let you wire for common mono-amp loads without a second woofer.

Aramid IMPP and butyl surround
Aramid-fiber infused IMPP stiffens the cone for punchy, controlled bass, while the butyl surround supports long travel. Fs is 34 Hz with 13 mm Xmax across 20 Hz to 4.7 kHz at 78 dB.

1.0 cu. ft. boxes and 6-1/8-inch depth
Pioneer lists 1.0 cu. ft. for both sealed and ported starting points. Mounting depth is 6-1/8 inches. Confirm cavity space and feed the woofer near 600 W RMS.
