From the page... "A dipole bass system has a "figure of eight" response pattern, which is entirely different to the "spherical" response pattern of your typical "monopole" subwoofer. The system's output is most powerful directly in front and behind the baffle, and decreases to zero at the sides, where the front and rear waveforms cancel each other. This response characteristic is said to be one of the major advantages of a dipole bass system, as the restricted dispersion results in fewer boundary reflections, which in turn is supposed to result in a smoother in-room response." Note - I haven't built one of these things yet, so I can't confirm this particular advantage isn't just hypothetical. Brian
