Kijanki ... add Paradigm to the list, at least their high end speakers. The company also makes its own drivers. That's a big reason why Paradigm can pack so much speaker into such a reasonably priced package.
Particularly noteworthy is their beryllium dome tweeter and cobalt/aluminum alloy cone midrange driver. Both drivers also use (i) ferro fluid to cool and stabilize the motors, and (ii) super neodynium (sp?) magnets to increase SPL and lower distortion.
