- EXTREME KOREAN-BUILT POWER: The Synergy Mobile Audio WFO 2.1D mono Class D amplifier is designed and manufactured in Korea using premium components, overbuilt power supplies, and heavy copper circuitry for extreme output and long-term reliability.
- MASSIVE REAL-WORLD RMS OUTPUT: Delivers up to 2800W RMS at 1 ohm @ 14.4V and 3200W RMS at 16V, making it ideal for high-power subwoofer systems, demo vehicles, and SPL competition builds that demand sustained current delivery.
- BUILT FOR DAILY DRIVERS & COMPETITION SYSTEMS: Stable at 1 ohm, with a wide operating voltage range of 8V–16V, the WFO 2.1D performs consistently in daily-driven vehicles, ground-pounding demo builds, and high-voltage competition systems.
- PRECISION BASS CONTROL & TUNING: Features adjustable subsonic (10Hz–50Hz) and low-pass (35Hz–250Hz) filters, high damping factor (>200), and low noise floor (>100dB S/N) for tight, controlled bass reproduction.
- OVERBUILT CONSTRUCTION & CONNECTIONS: Equipped with 0-gauge power and ground terminals, nickel-plated 8-gauge speaker outputs, hand-soldered Tiffany RCA inputs, multiple power transformers, and a high-mass aluminum heat sink for superior thermal management.
