Here's a few more to add to your list.
Brentworth Sound Lab. I like this companie's thinking. This sure resembles the design theory behind my current speakers.
Royal Devices loudspeakers This company doesn't use crossovers on the woofers of their speakers. They look great..I wonder if they sound as good as they look.
Audio Note Loudspeakers. Looks like very simple crossovers to none at all used in these speakers.
RL acoustique
Carfrae Horn speakers
