dunno the condition of the compression driver nor which is in it - too much hassle tonight to pull the back. I should have pulled the glorious copper clad aluminum junk wire away from the K-tube so it could be better seen. - poked an X15 clone (~1966) K-tube - about 7.25 inches long into the front chamber's exit hole. There's a concentric sliced piece at the throat of this tube. I grabbed a generic textbook value Eminence 1K6 network and twisted some wires to the terminals its loaded with an EVM18B and has run two different spec Eminence 18s - all "listenable" (106 & 130 grams moving mass - Id guess the EV18 to be in the low 70s moving mass) There's a rear shelf / lowpass filter - the upper portion of the front chamber is curved, I've enjoyed opera, pop and rock on this crazy thing in years past HEAR HERE ON YOUTUBE Karlson Evangelist
