John Dong and Larry Ullman founded EA in 1981 to design speaker systems for audiophiles. Dissatisfied with the "state of the art" products available in the high-end audio market, John and Larry auditioned popular and critically praised speakers to determine the relationship between the physics of the design and the sound of the speakers. Data was compiled on hundreds of speaker systems. Every raw driver we could obtain was evaluated and the history of speaker design was thoroughly. We determined that theories advanced in the 30's, 40's, and 50's include the basis for impressive products if modern material and computerized instrumentation are used.

In 1995, Michael Tobias (MTD Basses) and Dan Lakin (Lakland Basses) proposed us two challenges. First, could we design and build a speaker system that would produce usable, high SPL (Sound Pressure Level) in a small, compact and easy to carry package. The second part of the challenge would revolutionize the world of bass amplification. Both Mike and Dan had players who loved their DI sound in the studio but had difficulty reproducing that sound in a live setting. They challenged us to make this high power, easy to carry speaker system match the DI sound that players loved in the studio, in a live setting.

EA has focused on the amplification of musical instruments, with three goals in mind: wide dynamic range, wide dispersion, and extended bass response to accurately replicate the full range of every instrument, including the fundamentals of the low E and B-strings on electric bass. Our Class D amplifiers have an honest power rating throughout the full bandwidth – meaning you’ll get true power throughout the entire audio spectrum, from 20-20KHz; input level control and metering; highly effectual and intuitive tone shaping controls; professional balanced outputs (with a Jensen transformer option for the Direct Input section); versatile parallel and series effects processing; rugged steel construction and more.
