Introducing the Pro-X Series

Pro-X is the line of high sensitivity wide-band professional woofers from Earthquake
Sound. Built with the accumulative knowledge and expertise gained from
manufacturing industry defining woofers for 30 years. Pro-X is proof positive that the
combination of high performance and superior value is possible!

ForFor years it’s been our analysis that the pro woofer market has a huge split between
performance and value. The leading brands build $1500+ starship woofers and an
almost unending slough of no-name brands flood the market with cheap, but
essentially worthless woofers. We offer Pro-X as the meaningful solution. Providing
near enterprise level performance at less than a third of the cost.

Building the Pro-X

Typically when designing a statement
product its an exercise in the use of exotic
materials and blatant disregard for the cost
as a way of infusing exclusivity into the
product.

WithWith Pro-X the goal was just the opposite -
chip away all non-essentials and unearth the
raw essence of performance. During this
process we developed several technologies
and design attributes that would come to be
essential for the final product.

CAUTION: Earthquake's Pro-X woofers are capable of generating high sound
pressure levels. You should exercise caution when operating our woofers and
amplifiers. Long term exposures to high levels of sound pressure will cause
permanent hearing damage. Sound pressure levels exceeding 85dB can be
dangerous with constant exposure. Earthquake Sound Corporation does not
assume liability for damages resulting from the direct use of or other Earthquake
products, and urges users to play sound systems at moderate listening levels for
everyday use.everyday use.
