Each guest room at San Francisco Proper Hotel is outfitted with Vifa Helsinki wireless loudspeakers, handpicked by Kelly Wearstler. Each high-end Vifa speaker is a celebration of authentic sound, premium materials and technology–all brought to its fullest expression by a simple yet sophisticated Nordic design. A collaboration with Kvadrat, Europe’s leading manufacturer of design textiles, is one of the more important components to the look, feel and sound of the Vifa loudspeakers. The Helsinki speaker has a special-woven Kradrat textile cover, giving the product a warm, rough look and feel, without compromising the sound; the textiles have been designed to let sound pass through the threads in the best possible way. The solid aluminum frame is molded in one piece to avoid any assembly marks or frail spots. And the leather strap has been carefully selected and crafted by Swedish leather manufacturer Tärnsjö Garveri.
