The dual 2-ohm voice coil offers flexible wiring configurations to match your amplifier, while the rear-threaded magnet system allows bolting to the enclosure back wall to reduce cabinet resonance. This DIY-friendly package includes a protective grille, trim ring, and gold-plated terminal for a complete installation solution.
