ME-640 -  Absolutely the most power and quality for your money . The Earthquake ME-640 subwoofer plate amp  is the  leader in power, quality and price. No amplifier in its class offers more power and more features than ME-640.

Designed, developed and rationally produced at Earthquakes own factory. This
ensures  high performance, overbuild construction and a sensational low price. Here, quality is not gobbled up by 10 middlemen.

The amplifier is built around Earthquakes  Evolved Class D amplifier technology. It uses an efficient and low frequency optimized PWM switching output -  resulting in  exceptional powerful control over even large and heavy woofers. The amplifier is equipped with 6 high ampere discrete transistors for high and continuous current. No cheap monolith output modules here.

The oversized Evolved Class D amplifier has an efficiency of 90% which means that the amplifier does not get hot even with hard and continuous operation. This unique class D design distinguishes itself with high performance and superb bass control. Even the most complex source material is reproduced with precision.

The power supply is based on Earthquakes Triple Triangle Constant Power Transfer Technology. It is an advanced industrial switch mode power supply technology, inherited from Earthquakes military power supplies. It guarantees constant high performance even with heavy loads, all with minimal power loss and heat generation.
