I'm looking at the speakers with, what, hinged side panels?
Found
something:
"Introducing the BafFLEX by HFC. Prototype open baffle design with flexible side panels allowing you to load your room differently. NO crossover - all drivers running full range. Ribbon tweeter has a Duelend cap on it. Front panel is bronze with a Ceracoat covering. The flexible side panels are ceracoated aluminum and decoupled from the front panel with a unique hinging system. Resonance control footers are Audio Points by Star Sound. Of course, our patented acoustic lens, magnetic cabling, wave guides and magnetic binding posts are all in effect."
