Dynamic speakers

Other than Klipsch and I guess the unaffordable Avantgarde, what other recent high efficiency speakers designs are out there?

I have enjoyed the refined sound of KEF for some time now, but I switched back to Klipsch for that dynamics...
tannoy would be another to consider
Had a Horn Speaker from South Korea - Kochel 300 - some years go. 99 dB, horn midrange, slot horn tweeter. That one was exceptional in speed and holographic reproduction.
