About Earthquake Sound
Earthquake Sound Corporation is headquartered in Hayward, California. It was founded in 1984 by Joseph J. Sahyoun, an aerospace engineer, built its name in car audio, and moved into home audio in 1997. This page covers the home and commercial range.
Its patented SLAPS passive radiator, the Symmetrically Loaded Audio Passive System, uses two identical suspensions so the passive cone moves the same amount of air in either direction. Earthquake says this gives louder bass without more amplifier power.
Morion Automation is the authorised distributor in India.
Home and commercial rooms, indoors and out.
Subwoofers, bass shakers, in-wall and outdoor speakers, amplifiers, and a 70V/100V line for restaurants, retail and hospitality.

Quick answers
Who makes Earthquake Sound, and where is it designed?
Earthquake Sound Corporation, headquartered in Hayward, California, and founded in 1984 by Joseph J. Sahyoun. Its product plates say designed in the USA.
Why can't I hear the deepest notes on my laptop or phone?
Small speakers cannot move enough air at very low frequencies. The page turns the bass in each clip into movement, so you can see what a small speaker cannot play. Only a subwoofer or a bass shaker reproduces the lowest notes.
What is a bass shaker?
A tactile transducer. It is fixed to a seat or platform and moves it with the low frequencies, so you feel film effects without raising the volume. The Q10B covers 5 to 40 Hz and the MQB-1 15 to 50 Hz. Both need an amplifier.
Does this page cover car audio?
No. It covers the home and commercial range only.
What are the bass lines on this page?
Thirty-second excerpts of commercial recordings. The bass range shown for each is measured from the excerpt. They were not recorded through an Earthquake product and do not show what any product sounds like.
