A few people have contacted me for the crossover component values most recently. The woofer's crossover was reworked post break-in, as the slight peak @ 500Hz all but disappeared once the stiff suspension loosened up a bit. This allowed for a more conventional second order electrical low pass, with an added resistor to shape the bass circuit. Instead of using a single electrolytic cap, I opted for a sandwich of three caps adding up to the required value. This allowed me to combine two inexpensive electrolytic caps and a third poly cap for better sound. The combined wire gauges also approximated that of the 14 AWG Solen inductor used in the same circuit.
The Eikona needs only one 33 ohm resistor in series to perfectly level-match the woofer. No other components in the full-range driver's circuit. Don't skimp here. I find that using the Mundorf M-resist Supreme resistors are about as transparent as one can get. The combined drivers present a very friendly load to most amps, about 7.9 ohms.
