@sns , no they don't. You are mistaking venue depth for 3 dimensional imaging. I have spent hours with K horns set up perfectly using early Krell amplification. These speakers as they are, are incapable of relaying the third dimension. This is a common misunderstanding many listeners have because they have never heard a system image correctly. I was an audiophile for almost 20 years before I heard a system that imaged the third dimension and it was not my system. I was flabbergasted. I spent another 10 years trying to get my system to image the same way and to understand what the requirements for proper imaging were. They all center on the speakers and the room. For multiway speakers the crossover, group delays and phasing are major issues. The K horns major fault is that it has three different group delays. The difference at the woofer/midrange crossover which use to be at 500 Hz and is now at 350 Hz is huge. Lowering the crossover may have helped a bit but I would be stunned if it resolved the problem entirely. That crossover is right at middle C.
