Patrick has correctly described the set-up of a bi-amped active Keilidh, and the issue is what happens if you add a third LK 100, with the result that each side of each amp is only driving one driver. In a bi-amped set-up, each side of the treble amp only drives one driver, but each side of the mid-bass amp is driving two drivers.
Marc, the improvement that you are hearing could well be the result of adding a better amp into the mix, rather than as a result of tri-amping. Certainly, in discussions with the dealer, he felt that I would be better off buying two new LK-85s and new active cards, but this was far more expensive and in any event he hadn't heard an LK 100 tri-amp set-up.
To recap, my Keilidhs are bi-amped, tri-wired and active, and the question arose when I saw that there may still be a set of active Keilidh cards for sale on this site, as well as several LK 100s. Many thanks.
