RW10D4 - Echo Series 10 Inch Subwoofer - 500 Watts Power Dual 4 OHM Voice Coil, 2" Black-coated 4 Layer High Temperature Voice Coil, Competition Grade Pressed Paper Cone

The RW10D4 is a 10-inch dual 4-ohm subwoofer built for daily use where efficiency and long-term reliability matter. Its single slug ferrite motor and high-temperature 2-inch copper voice coil handle sustained high output without thermal rolloff. Punchy low-end response and a wide enclosure compatibility make it a practical choice for a range of daily driver builds.

• Dual 4-ohm voice coil — wires to 2-ohm or 8-ohm final impedance for flexible amplifier matching
• 250W RMS / 500W peak — rated for extended play at peak levels without thermal failure
• 2-inch (50.8mm) high-temperature copper voice coil — handles heat buildup during prolonged use
• 36 oz. single slug ferrite motor — strong, consistent magnetic field for efficient power conversion
• Pressed pulp cone with cotton fibers — balances rigidity and damping for accurate transient response
• Advanced cooling structural design — promotes airflow through the motor assembly to reduce operating temperature
• 34 Hz – 400 Hz frequency response — reaches into the low bass range while remaining responsive across the midbass region
