RW10D2 - Echo Series 10 Inch Subwoofer - 500 Watts Power Dual 2 OHM Voice Coil, 2" Black-coated 4 Layer High Temperature Voice Coil, Competition Grade Pressed Paper Cone

The RW10D2 is a 10-inch dual 2-ohm subwoofer built for daily use where efficiency and reliability matter as much as output. Rated at 250 watts RMS with a peak of 500 watts, it handles extended high-output sessions without thermal rolloff, thanks to a high-temperature 2-inch copper voice coil and an advanced cooling structure. The pressed pulp cone with cotton fibers and high-roll foam surround give it the flexibility to reach down to 34 Hz while staying responsive across the range.

• 250W RMS / 500W Peak — capable of sustained output without thermal stress
• High-temperature 2-inch copper voice coil — handles extended play at peak levels safely
• 36 oz. ferrite magnet motor — single slug design for focused, consistent magnetic drive
• Pressed pulp cone with cotton fibers — balances low-frequency extension with transient response
• High-roll foam surround — maximizes excursion for deeper, more accurate bass
• Advanced cooling structure — optimizes airflow to sustain performance under load
• 34 Hz – 500 Hz frequency response — versatile range suited to a wide variety of enclosure types
