Where the Sonesse 50 fits
The Sonesse 50 suits wide living room shades and groups of coupled shades across a window wall, the typical layout in Brickell, Sunny Isles and Fort Lauderdale beach condos. At Landmark Ranch Estates in Southwest Ranches we ran coupled rollers on Sonesse 50 motors in ceiling pockets, controlled from the home's keypads. For the quietest option in the same size class, compare the Sonesse ULTRA 50.
