The first speaker I reviewed for Stereophile was the Alon IV by Acarian Systems, designed by Carl Marchisotto . I remember it as being a very good-sounding speaker, with outstanding bass, and the dipole midrange giving it an “open” sound. Through the years, for business reasons, the speaker brandname has changed (Nola is Alon spelled backwards), and the company is now called Accent Speaker Technology, but the speakers are still designed by Carl, and his wife, Marilyn, is the company’s wife president. Carl’s more expensive speakers still use the dipole midrange arrangement, but in the more affordable line he has turned to the more common unipolar approach, albeit with his own variations, like separate porting of bass drivers. The latest such speaker, introduced at the 2011 CES, is the Contender ($3400/pair), and it sound like. . .well. . .a real contender.
