The "Victoria EVO and Iguasçu EVO are slim, pure-glass towers standing 40 inches high but just 10 inches wide. The Victoria EVO, a three-way/four-driver design, includes Waterfall's proprietary, downfiring, 8.5-inch passive woofer, the Iguasçu (34 inches tall by 10 inches wide) employs identical drivers (including the passive woofer) in a two-way/three-driver arrangement. Both models use a key Waterfall technology: the Acoustic Damping Tube (ADT), which performs near-total damping of mid- and low-frequency 'back-wave' artifacts, and precise damping control of midrange reflections, allowing the speakers to produce superbly accurate, high-end performance within their effectively undamped glass enclosures."

The speakers will be available by March 2008, with the Victoria Evo retailing for $5,400/pair and the Iguasçu Evo $3,900/pair.
