For earth shattering bass you can’t beat this custom made 60-inch subwoofer which has the ability to produce SPL levels above 180 dB. This monster has ouput displacement comparable to 160+ ten-inch woofers! More after the jump.
“The motor is capable of producing 6,000+ pounds of linear force, which is necessary when considering the very large surface area and displacement volume required to produce high SPL levels.”
