This is a Special Order item.

The Supernova MKVI Series epitomizes the state-of-the-art in subwoofer design. The MKVI series is uncompromised performance and superior technology coupled with the world's most refined low frequency  response. The MKVI defines a new standard  in a class of its own. The selection of subwoofers is vast, but at the top Supernova MKVI reigns in solitude.

With more patented technologies and test awards than any other subwoofer, the MKVI continues the legacy of the legendary MKV series. MKVI differs from its predecessor with the introduction of the revolutionary IQ600 class J amplifier and full DSP with phase and time control. Patented technologies such as Class J amplifier technology, Overdrive, ODL, SLAPS, DBXI and Magma X define MKVIs groundbreaking performance. If you dream of uncompromising LFE performance with superb dynamics and effectiveness-, combined with quick and precise articulation, the MKVI is the obvious choice.  The MKVI can effortlessly produce the lower octaves in a high-end stereo setup or add explosive LFE effects in large surround sound systems.

MKVI's brute force springs from the newly developed IQ600 class J amplifier. The patented Class J technology manifests a quantum leap in amplifier technology. The revolutionary aspect of Class J is its ability to combine a high efficiency of 99% with extraordinary bass control. Class J is an evolution on PWM technology that combines advanced multi-level feedback with an intelligent controller. It modulates the supply voltage and output switching frequency in real time based on the frequency and amplitude content of the input signal. This added level of intelligence to the amplifier offers several obvious advantages such as increased thermal headroom through the amplifier's optimum energy use, dramatically improved bass response and dynamic power capabilities.

SLAPS technology is a key player in translating the IQ600 amplifier's high power into dominating LFE. SLAPS is a patented system that dramatically increases subwoofer efficiency and capability for ultra low frequency reproduction. SLAPS stands for Symmetrically Loaded Audio Passive System. As the name indicates, SLAPS is built symmetrically which distinguishes it from traditional passive devices. SLAPS integrates identical components in its suspension and design ensuring the unit is moving identically in both directions. The revolutionary efficiency and performance are the result of the pneumatic coupling between SLAPS and the active driver DBXI/MagmaX. SLAPS overcomes the limitations known from conventional closed and ported designs that prevent radical excursion and deep response. The unique design allows the active driver compression-free movement resulting in deep, dynamic and hard-hitting bass response.  

The  MAGMA driver in MKVI12 effectively converts electrical energy into physical movement. The mechanical construction is 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 voicecoil former, this exponentially increases the surface contact of the cooling air. The result is a 3 db increase in sound output at rated power compared to the same transducer without TCT.
