Crossover design has normally nothing to do with bass extension. The
bottom end of a passive loudspeaker's response is left to roll off
naturally, the frequency at which it does so is a function of driver
and cabinet.

IIUC Some loudspeakers use a large capacitor in series with the LF unit to
alter the low frequency behaviour and interaction with the cabinet effects.
I think KEF did this with various speakers, but I don't know how widespread
the practice may be.
