The later K55V and K55M drivers do not have this problem. These early drivers simply have a rough frequency response in the 4000 - 6000 Hz area. The claim is that the early K55V drivers (those with push-pin connections) will not reach the 6000 Hz crossover. It has been suggested that the squawker to tweeter crossover should be changed from 6000 down to 4000 Hz. Energy wisely used for a specific purpose, in this case, to give your amplifier a constant load, is NOT wasted power! The swamping resistor is a win-win situation in all respects. This is undesirable because it does bad things to your amp and to the filters in the network. With a transformer alone, as with the Klipsch network designs, the impedance seen by the amp rises to reduce current, and therefor the power, drawn form the amp instead. No matter if the midrange is attenuated with an L-pad, a transformer alone or a transformer and swamping resistor the efficiency will measure the same with 2.8V applied! You have intentionally adjusted it to be so by attenuating the midrange to match the woofer! A swamping resistor or a resistive L-pad absorbs the extra efficiency of the midrange that you don't need. The midrange is always attenuated to match the woofer, which determines the efficiency. To the idiots who insist that the 'swamping resistor' used in ALK network circuits to set the midrange level absorb power reducing the efficiency of the speaker, consider this: A loudspeaker's efficiency is defined as the loudness in dB sound pressure level at 1 meter from the speaker when 1W of power is applied.
