did you tilt the mini-K's portboard forwards about 10 degrees? one of my fave Karlson is the first K12 form 1955 - I had a blueprint but think my kid threw it out. Its the same size and tapers (42.5" radius) as later K12 but had a reversible perpendicular port board with lip on one side plus a 3-position wood bar on the rear panel to vary its lowpass choke action - - maybe this would scale to 10" giving high cutoff but a lot of punch (?) - - I need one in mahagony "Karlsonite" to make a pair
vent was a horizontal slot 15/16" high and full-width (minus ~1.5" for two pine cleats) it wculd sing on bowed bass despite no low bass
