Eeathquake Sound Information

Have you ever heard the expression, “It’s not rocket science”? Well for the Earthquake Sound Corporation it was exactly that. Founded in 1984 by Aerospace Engineer Joseph J. Sahyoun, Earthquake Sound exploded into the car audio industry revolutionizing the way sound was interpreted. Earthquake’s vision was to create a sound that is not only clean but also powerful and loud without losing quality. With his engineering background Mr. Sahyoun was able to push the boundaries of technology to establish subwoofers that he himself could live with. From that point on Earthquake Sound has been a leading car audio company and has expanded into the home audio, and other audio solution fields. Earthquake Sound has been awarded numerous Design and Engineering Awards for over a few decades now and their founder has been granted many design patents by the USPO. Earthquake Sound products are of highest quality, performance, and affordability. They are able to export products to over 50 countries, making them a very well known and trusted name.

Earthquake Sound entered the car audio industry and made a name for themselves in car subwoofers, and nothing could be more true to their name than their HoLeeS series subwoofers. These subwoofers offer unsurpassed bass and quality, and are equipped with amazing technologies and patents. There is no denying that this is the essence of Earthquake Sound. Other well known and equally amazing series of subwoofers include the award winning Subzero series, SWS (for shallow mount use), and Tremor-X to name a few. All of these series of subwoofers offer quality bass reproduction for any situation and any application. Getting better sound reproduction from your high and mid frequencies is equally important to Earthquake Sound. Their VTEK, Focus, and TNT series of speakers all provide different levels of sound reproduction, from smoother sounding speakers to speakers that are equipped for better higher frequency reproduction. Any of the Earthquake Sound speakers will provide you with a fuller and wider sound spectrum, making your car audio system sound the way it was meant to sound. When it comes to sound Earthquake Sound offers numerous series to satisfy any car audio enthusiast.

Subwoofers and speakers are nothing without proper power and Earthquake has amplifiers to meet any power needs. From their high-rated Power House series to their high-level TNT series, Earthquake amplifiers offer clean, efficient power, with minimal distortion and features that allow complete control of your sound reproduction. Much like their subwoofers, their amplifiers feature award winning designs and recognized patents and technologies that really set Earthquake Sound as a prestigious car audio company with knowledge for quality and a thirst for revolutionary and industry standard setting products.

No car audio company is complete without the option of accessories. With amplifier installation kits, and equalizers, Earthquake Sound is able to offer any need for any installation. Earthquake Sound continues to improve their products and is always looking for the next best thing that will change the car audio industry. Their products will offer a sound that can’t be matched and once you’re hooked, you're hooked for life.
