Introduction

Thank you for purchasing the Magma subwoofer – the world’s leading subwoofer in power, SPL and accuracy.

Back in 1995, Earthquake Sound Corporation led the industry in making the world’s true extra long stroke subwoofer by unleashing the Magma subwoofer line. The Magma introduces many innovations to the audiophile community, as follows:

•1st super wide edge surround to allow LONG EXCURSIONS

•1-1/4” spider mounting height to allow for 2.5” PEAK TO PEAK MECHANICAL EXCURSIONS

•Stacked magnet with huge bump back plate to create high excursion MOTOR

•Light-mass flat piston to REDUCE CONE DISTORTION while maintaining high speed

•6 back plate holes to create massive cooling in the gap

Upon its release, the Magma toppled DB drag records one by one like a bowling ball rolling through the lane. For over 12 years, the Magma reigns over the competitions in sound quality, power and accuracy. While Magma performance pushed the boundaries, the newly released Magma 15X ripped 'em apart.

Thank you,

Joseph Sahyoun, President
