from 3 to 5.5 ohms. This means that the power amplifier will need to be able to drive a 3 ohm load (we make amplifiers like that). On the plus side, the amplifier sees a relatively flat impedance, and much less of the reactance of the crossover and loudspeaker drivers.

After developing the initial versions of this crossover, we spent the next two years refining the details of the sound with our five in- house listeners and their individual environments. We established the closest “average” desired response, and created adjustments in mid-bass, midrange, and high end to accommodate a modest range of room characteristics and taste. The final circuit contains only the finest components – polypropylene capacitors from Kimber and Solen, Mills resistors, and high current Erse inductors, all mounted on thick heavily plated circuit boards. The wire is the same used in the output stages in Pass amplifiers.
