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.
