Synergy WFO 5.1D 7,000 Watt Monoblock Amplifier

The Synergy Audio WFO 5.1D is a 7,000-watt monoblock amplifier built for extreme bass in daily drivers or SPL-focused builds, leveraging high-end Korean design and rugged, thermally optimized construction.

• Power @ 1 Ohm: 7000W @ 14.4V. In real-world use, it delivers maximum current into a single-channel subwoofer load for high-output bass performance.
• Power @ 2 Ohm: 4500W @ 14.4V. Supports strong performance with a moderate load, useful for multi-coil subs or paired subs on a shared channel.
• Power @ 4 Ohm: 2100W @ 14.4V. Provides solid output into higher impedance subs while maintaining efficiency and stability.
• Power @ 1 Ohm (16V): 7600W @ 16V. Indicates headroom at elevated supply voltage for even more dynamic bass under ideal electrical conditions.
• Frequency Response: 12Hz–250Hz. Bass-focused range designed to reproduce low-end fundamentals and sub-bass content with clarity.
• Signal to Noise Ratio: >100dB. Low noise floor helps keep reverberant bass clean and free of audible circuitry hiss at high output.
• Damping Factor: >200. Contributes to tighter control of woofer motion and more precise bass definition at high excursion.
• Subsonic Filter: 10Hz–50Hz. Attenuates ultra-low content to protect subs and reduce unnecessary cone movement.
• Low Pass Filter: 35Hz–250Hz. limits upper bass frequencies to shape the subwoofer output and prevent muddiness from higher frequencies.
• Power & Ground Terminals: (2) 0 GA. Dual 0-gauge inputs for optimized power delivery and grounding in high-current installations.
• Working Voltage: 16V. Indicates operating voltage designed to support headroom in capable electrical systems.
• Power Transformers: Four. Multiple transformers provide robust power delivery and stability under demanding use.
• PCB: Heavy Duty 2oz printed circuit board with thick copper traces. Built to handle high currents with reliable signal paths and durability.
• Size: 620mm L x 239mm W x 69mm H. Large footprint reflects its high-power design and heat dissipation needs.
• Construction Features: Custom high-mass, thermally optimized aluminum heat sink casing; overbuilt power supplies; heavy duty double-sided through-hole PCB with thick copper traces; hand-soldered nickel-plated Tiffany RCA inputs/outputs; nickel-plated power/ground inputs (1/0 and 4 AWG) and 8 AWG speaker outputs; fully linkable/strappable (Mono-block); input sensitivity 8V–200mV; +18dB Remote Gain control; multi-way intelligent protection circuitry.

Benefits: In a true subwoofer–centric system, the WFO 5.1D powers a dedicated mono-channel pathway with substantial current capability, while the dual 0 AWG inputs and nickel-plated connectors support reliable, high-current wiring. The adjustable subsonic and low-pass filters let you tailor bass response to your enclosure and subs, and the thermally optimized heat sink plus four transformers keep performance consistent under aggressive duty. Its mono-block design and remote gain control give you precise, hands-on level management in a high-output install, making it a fit for daily-driven vehicles, demo builds, or SPL-focused setups.
