Its dual 4-ohm voice coil configuration provides flexible wiring options for a wide range of mono and multi-channel amplifiers, while the 2.5-inch aluminum bobbin voice coil ensures reliable power handling and long-term durability.
Earthquake’s patented TCT™ (Turbine Cooled Transducer) technology improves cooling efficiency, helping reduce heat build-up and distortion during high-output operation.
The DBXi-12D is equally capable in sealed, ported or bandpass enclosures, making it an excellent choice for daily drivers, SPL-focused systems and custom car audio installations.
