PW10D4 - Echo Pro 10 Inch Subwoofer - 1,200 Watts Power Dual 4 OHM Voice Coil, 2.5" Black-coated 4 Layer High Temperature Voice Coil, Competition Grade Impp Cone

The PW10D4 is a 10-inch dual 4-ohm subwoofer built for sustained high-output performance in demanding car audio setups. Its 4-layer high-temperature copper voice coil and advanced airflow cooling system allow it to run at peak power for extended listening sessions without thermal rollback. At 600W RMS with a 1200W peak, it delivers authoritative low-end response from 29 Hz up through 400 Hz.

• 4-Layer High-Temperature Copper Voice Coil: Handles sustained power with reduced heat buildup, rated for long-duration high-output use.
• High-Flux Ferrite Motor: Provides strong magnetic drive for accurate, forceful bass reproduction across the full frequency range.
• IMPP Cone Construction: Injection-molded polypropylene cone offers stiffness and light weight for improved transient response.
• Polycarbonate Spider Suspension: Custom-designed for consistent excursion control and enhanced mechanical responsiveness.
• Integrated Airflow Cooling System: Actively manages heat during high-excursion operation to protect voice coil integrity.
