RW12D2 - Echo Series 12 Inch Subwoofer - 600 Watts Power Dual 2 OHM Voice Coil, 2" Black-coated 4 Layer High Temperature Voice Coil, Competition Grade Pressed Paper Cone

The RW12D2 is a 12-inch dual 2-ohm subwoofer built for daily use, handling 300 watts RMS with a 600-watt peak rating. Its single slug ferrite magnet motor and advanced cooling structure keep performance stable during extended high-output sessions. This is a driver engineered for efficiency and reliability without sacrificing low-end reach down to 33 Hz.

• High-temperature 2-inch copper voice coil handles sustained power without thermal breakdown during long listening sessions.
• 40 oz. single slug ferrite magnet motor delivers consistent, punchy output across a wide range of enclosure types.
• Pressed pulp cone with cotton fibers balances rigidity and flex for accurate transient response and low-frequency extension.
• High roll foam surround allows deep excursion while keeping cone movement controlled and predictable.
• Advanced cooling structural design manages heat buildup to maintain output at peak levels over time.
• 33 Hz – 350 Hz frequency response suits both ported and sealed enclosures across a range of music genres.
• Dual 2-ohm configuration gives flexibility to wire at 1 or 4 ohms to match your amplifier's stable load.
