The Niagara Platinum edition is designed to be used in esoteric HiFi systems, exceptional home cinema systems and larger acoustic spaces. Aptly named after Niagara Falls, the Waterfall Audio Niagara speaker does look like it’s in water and is spec’d at 500-watts of power — without clipping — and with an efficiency rating of 89dB (2.83V/1m). The Niagara Platinum’s enclosure of 10-millimeter safety glass stands 48 inches tall and weights 100 pounds a piece, and retails for $39,500/pair. Yes, $40,000 a pair.
