given only on-axis response, which of these 2 midrange K-coupler to try?

assuming passive filters and no active EQ.

Where would you place the lower crossover points? There's very little xmax.

Karlson cabinets work well fullrange and w. coaxial, but I'd like to try a mid-K to hear if there's some advantage at high spl and complex music. It could help fill in the area between a one inch format K-tube and woofer.

I have both drivers.

Aperture bracing might be needed to limit modulation.

maybe they could use aperiodic venting - most likely would run a passive
crossover at first.
