PW12D2 - Echo Pro 12 Inch Subwoofer - 1,400 Watts Power Dual 2 OHM Voice Coil, 2.5" Black-coated 4 Layer High Temperature Voice Coil, Competition Grade Impp Cone

The PW12D2 is a dual 2-ohm, 12-inch subwoofer built for sustained high-output performance in demanding installs. At 700W RMS and 1400W peak, it delivers authoritative low-end reproduction from 25 Hz to 400 Hz without thermal compromise. The dual voice coil configuration gives installers flexible wiring options for 1-ohm or 4-ohm final impedance loads.

• 4-layer high-temperature copper voice coil — 2.5" (63.5mm) diameter construction rated for extended high-power operation without thermal degradation.
• High-flux ferrite motor — 108 oz. magnet assembly drives precise, controlled bass response across the full frequency range.
• IMPP cone material — Injection-molded polypropylene cone balances rigidity and mass for accurate low-frequency pistonic motion.
• Polycarbonate spider suspension — Unique material choice improves linearity and durability compared to standard woven fabric spiders.
• Advanced airflow cooling system — Engineered venting keeps the voice coil and motor assembly cooler under sustained load.
• 700W RMS / 1400W peak power handling — Matches a wide range of mono amplifiers in the 500–1000W RMS class.
