DD Audio 712g-D4
The new DD Audio 700 “G” revision includes major upgrades to the motor: longer coils, thicker top plate with a deeper gap, and an increased 280 oz magnet assembly. The 712g-D4 is the 12-inch dual 4-ohm model and extends Xmax to 30 mm each direction – longer coils enable longer strokes, pushing more air in each cycle for high-impact, low-frequency response, while the thicker top plate adds thermal mass and the deeper gap keeps the coil under control.
Key Features
- 3″ CCA Hi-Temp Voice Coil: Longer coil for extended stroke, dual 4-ohm configuration
- Triple Stack Magnet Motor, 280 oz: Motor force to control the extended stroke and 2000 W RMS
