DBXi-12D
DBXi-12D showcases the use and adaptation of extremely advanced technology. DBXi simplifies the choice for serious bass enthusiasts. Deciding whether the subwoofer should be an SPL or SQL design is no longer necessary. DBXi provides high SPL while remaining fast, accurate, and musical. Innovative technology and a revolutionary machining process are key elements of the DBXi design. This enables us to produce a subwoofer capable of thunderous deep bass with speed, precision, and articulation.

MAGMA-12X
Upon its release, Earthquake’s MAGMA-X drivers toppled DB drag records one by one like a bowling ball rolling through the lane. The MAGMA-12X effectively converts electrical energy into physical movement with a mechanical construction of superior quality, evident in the almost absurd over-building of all components.
This is further enhanced by adding TCT (Turbine Cooled Transducer) technology. TCT is a patented earthquake-exclusive technology that implements a fixed turbine vane impeller in the magnet gap. It forces the drawn-in air to rotate in a vortex pattern against the aluminum voice coil, exponentially increasing the surface contact of the cooling air. The result is a 3db increase in sound output at rated power compared to the same transducer without TCT.
The intelligent MAGMA-X design with an overbuilt motor system results in a device that is always electrically controlled by the amplifier. The strong reactive electromagnetic coupling ensures the woofer remains compression-free and will not dampen itself mechanically. The high edge surround combined with the super spider allows for huge excursion. The driver’s electrically controlled and mechanically unhampered movement results in a transient response with previously unheard-of dynamic capability.
