Duke at Audiokinesis has introduced a new speaker called the Cloud Chaser that looks well-suited and I understand its closer to $2500/pair. Duke always makes very competent, easy to drive speakers that perform well above their price points so this is one to watch or just go out and buy :)

Minor correction: Actually Duke's $2500/pair speaker is the "Rhythm Prism", with the "Cloud Chaser" being a $3900/pair bipolar model. I think it's the Rhythm Prisms that Ralph is thinking of, as they can be tuned to take advantage of boundary reinforcement. Credit to Audio Note for their innovative and inspirational work in corner loading of low-tuned rear-ported reflex boxes driven by low-damping-factor tube amps. Credit to Atma-Sphere for making Duke's speakers look good at audio shows.

Hey Duke, there is no way they could sound like that if the speaker didn't have what it takes!
