Summary: Designer’s concept
The Continuum 3 is a result of five years of directed research into the most difficult

by 20 years of groundbreaking research—verifying others’ findings, developing and
testing new theories and measurement techniques, and recording and listening to
music. The Continuum 3 is the result of over 30 years of my life. It raises the bar of every
aspect of performance that’s too long been considered “the standard” in our culture. It’s
time for a change. I’m gratified to have developed a product that’s a true advance of the

art of loudspeaker design. I invite you to challenge all that I’ve learned with any music or
soundtrack, of any quality, at any loudness. In most any room—from nearly any
system—you’ll immediately find yourself truly there with the artists, and life will be
enriched beyond imagination. Hear it all. All you have to do is listen.
