Speaker 揚聲器 / Earthquakesound / MK VII 15

Earthquake's Supernova MK VII subwoofer is the product of meticulous engineering, detailed craftsmanship, and passion for performance, all geared to please the audiophile in every one of us.


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. This results in a harder audible impact that adds a drive to the sound normally experienced only at live concerts. This combined with superb articulation, nuances and details are reproduced by the MKVI, but overlooked by traditional subwoofers.
