yes - but as a conceptual sticking point - how does one size a Karlson's front chamber "volume" and when is there sufficient and low enough front resonant support? - besides the midrange "reverberation", are the 12" and larger coupler's providing damping of the important bass region overtones? - despite whatever resonances, a stock Karlson 12 with Eminence C12CX and APT50 sounds better on Garry Karr's bowed bass than my Klipschorns. Karlson had experimented with a one fold tapered line in his "Aural Optics" patent of 1955 but it was very short. A longer inverse K/transflex will model and work - possibly for "something" but there not much taper available in some skinny pipes with a single diagonal board.

Baronette are beautiful - I don't have to skill to cut them

whether deserving or not I attempt to keep Karlson somewhat visible ....
