without details we can't tell what innards those have - I made a one-sheet sealed rear chamber (~3 cubic foot) klam for 18" with baffle not much larger than the driver and it sounded pretty good, added a bit of reverb and subjective dynamics were improved vs direct radiator.z-transformation is supposely done by the aperture's variable leakage
wish k-builder Carl would give data to support his thoughts that longer k-chamber go lower and smoother - - -if they boil down to BP-like, then tuning the "front" real low would de-tune the passband.
