PW10D2 - Echo Pro 10 Inch Subwoofer - 1,200 Watts Power Dual 2 OHM Voice Coil, 2.5" Black-coated 4 Layer High Temperature Voice Coil, Competition Grade Impp Cone

The PW10D2 is a dual 2-ohm, 10-inch subwoofer built to handle sustained high-output use without thermal compromise. With 600W RMS and a 4-layer high-temperature copper voice coil, it's engineered for setups that demand consistent low-end performance over extended sessions. The wide frequency response of 29–400 Hz gives it versatility across both deep sub-bass and midbass territory.

• 4-Layer High-Temperature Copper Voice Coil: Sustains peak performance during extended high-power operation without heat-related degradation.
• High-Flux Ferrite Motor: 108 oz magnet structure delivers strong, controlled bass reproduction across the full low-frequency range.
• Polycarbonate Spider Suspension: Purpose-designed for improved responsiveness and consistent excursion control under load.
• Advanced Airflow Cooling System: Actively manages thermal buildup to support long-duration playback at high power levels.
• IMPP Cone Construction: Injection-molded polypropylene cone balances rigidity and low mass for accurate bass response.
• Dual 2-Ohm Configuration: Wires to 1 ohm (parallel) or 4 ohms (series), offering flexibility for a wide range of amplifier setups.
